how come ny state has released the chem curve so fast, yet this is taken for ever, it really killing me

June 17, 2010 am30 11:50 am 11:50 am

You’re absolutely right, Paul.

I thought that the curve was supposed to be a reflection of what students needed — it was supposed to come out after all the exams were graded, and be so made as to accomodate the majority of students.

Yet, NYS put out the Chem conversion chart fifteen minutes after the end of the exam and the English part II chart while the exam was STILL in progress!!

I don’t know WHAT’s going on with Trig, but I do know that a lot of students failed it, so the state is probably working hard to determine what percentage of students to accomodate: should the curve be 45, or 40, or 35?

The state does not want EVERYONE to fail, but at the same time it doesn’t want to anger teachers with an especially low cut-off (like 30, which is what it did for Algebra in June 2008 — and which upset a lot of teachers b/c that’s just ridiculous).

Another reason why this is taking so long is b/c this year marks the 1st administratiuon of the AlgII/Trig Regents: logically, it takes longer to come up with a conversion chart that the State never came up with before.

I think that the cut-off will be around 40 because this exam was never given before, so the students did not have anything to study off of (no previous exams, no idea what exactly would be covered…).

Good luck!

June 17, 2010 pm30 12:07 pm 12:07 pm

my teacher said there would be a log equation, regression,completing the square, factor by goruping and none of that was on there.. my guess is that nys is seeing what an apporiate curve is so that most of the kids pass, or they enjoy messing with us

June 17, 2010 pm30 12:11 pm 12:11 pm

First of all, no one knew what would be on the Regents exam b/c this was the 1st administration — the 1st of its kind.

Regressions are purely calculator work.

There was a log question, just in the mult. c., not the long-response.

There are so many Qs that they can ask (34 or 37, I think it was).

And, yes, a lot of people did terribly, so NYS is weighing its options.

It is not the case that NYS is “messing with” you; the teachers are just as nervous.

lET’S FACE IT: 1st test, it’s kind of hard to determine what the cut-off should be.

Let’s just be patient and hope for the best.

June 17, 2010 pm30 12:12 pm 12:12 pm

There are ONLy so many Qs that they can ask.

June 21, 2010 pm30 9:01 pm 9:01 pm

I’m 17 (just turned) and I took the “last” math b regents last June. It was incredibly easy, I got a 93 and I took just one practice test and did little additional study. I don’t consider myself an exceptional student at math at all, so I don’t see why so many kids are failing a regents thats suppose to be easier!! This is all so ridiculous, Teachers need to learn how to teach their kids, kids need to learn basic study habits. Also, I read that there were few questions with “Artificial information” or something. T_T if they cant understand “Artificial information” they must not have basic comprehension skills.

June 17, 2010 pm30 12:17 pm 12:17 pm

are you a math teacher

June 17, 2010 pm30 12:24 pm 12:24 pm

No, Paul, I am not a math teacher — just a student who knows the system very, very well.

• July 2, 2010 pm31 1:02 pm 1:02 pm

I think the old system of just taking the Regents tests without any curves whatsoever were best. You didn’t have to wait so long to find out what you got and the scoring meant something. They’re not hard to pass, or do well in, for that matter. The only requirement is that the student studies the material.
Now they give you the use of a graphing calculator, a whole reference sheet with formulas, and then curve the test. I think it’s pathetic how many kids get into high school without knowing enough basic math (such as fractions, multiplication and division, and order of operations). Then, because they don’t have a good grounding in math, they don’t do well in the upper classes of math and “need to” have a conversion chart put in place so that the students pass.

June 17, 2010 am30 11:59 am 11:59 am

That test was kinda hard

June 17, 2010 pm30 12:18 pm 12:18 pm

for the question in the long response where it was sinx=sin2x
the answers were: 0, 60, 180 and 300

If i did guess and check and i only got one answer (60) do u think ill get any credit if so how much.

June 17, 2010 pm30 12:24 pm 12:24 pm

If it was a 4-pt. Q and you showed your work, you would definietly get credit (1 or 2 pts.).

(BTW, you mistyped the Q — it was 2sin(theta)cos(theta) = sin(theta); but I know exactly which one you are referring to.

You won’t get all points (obviously), and depending on how much work you did, it’ll be 1 or 2 (3 isn’t likely, esp. b/c I don’t know what you mean by “guess and check”).

June 17, 2010 pm30 12:26 pm 12:26 pm

He typed it correctly, it was sin(2 theta) = sin(theta), but you had to substitue using the identity to yield, 2 sin theta cos theta = sin theta. In any case, if he got only 1 solution out of 4, he will probably get 1/4 points.

June 17, 2010 pm30 12:31 pm 12:31 pm

My fault, you’re right; he’s right.

but i don’t agree about the pts.

If you do all the substituting work, and jsut forget that you need ALL the values of x, do you really think that that is worth just a single point?

Clearly, if you sub and get to 60 degrees, you know what you’re doing.

June 17, 2010 pm30 12:36 pm 12:36 pm

I don’t know how plugging in random values, shows what you are doing. But based on what Porgey, said I think you should get 1/4, or at most 2/4, but high unlikely, so I’ll think of 25% credit for that question.

June 17, 2010 pm30 12:32 pm 12:32 pm

ill use x instead of theta since theres no theta key on my keyboard lol

But you are incorrect the original question stated sin2x=sinx….once you looked at the reference table you could see that sin2x=2sinxcosx. Thus you can state that 2sinxcosx=sinx

By the “guess and check method” i mean instead of solving it algebracially i just plugged in in values for “x” and since 60 worked i put it as my answer not knowing at the time that there were 3 other values that could have worked
According to the the speaker you could use the guess and check method as long as you took 3 guesses.
This is why im wondering if ill get credit for work and since i had 1/4 of the total answer im trying to figure out if I will at the least get one point

June 17, 2010 pm30 12:38 pm 12:38 pm

My fault, you did type everything correctly.

Guess and check does not mean that you check only the right answer and it works.

You have to do it three separate times (and make it not work 2 of those times).

So if you did that, I think that you will definietly get 2 or 3 pts.

Why couldn’t you solve it the normal way, though?

Good luck! We’re all praying for a low cut-off score (well, except for Noel, who probably got a 100 and doesn’t even need to see the chart…).

June 20, 2010 pm30 3:20 pm 3:20 pm

You would get 0 with a guess and check answer of 60

June 17, 2010 pm30 12:21 pm 12:21 pm

number 20 is that a secant graph

thanks

June 17, 2010 pm30 12:28 pm 12:28 pm

Noel, can you please send me the link of where you copied these from?

Did you copy just the long-answer questions, or the m.c. as well?

P.S. We all know that you got an 88!! Congrats; are you just as brlliant in your other subjects?

P.S.S. I am vying for valedictorian, so I just love chatting with smart people.

PSSS IT’s good to see that you’re back.

June 17, 2010 pm30 12:29 pm 12:29 pm

I based the m/c off what I put on my answer sheet, and the ones I didn’t remember, I worked out myself. The short answer I got from another post on this blog “Last minute tips”, and I got all these answers for short answers, and know how to get them, so I’m sure they all right for short answers. The m/c I think are all right, however I might have made an error or two transferring.

June 17, 2010 pm30 12:38 pm 12:38 pm

June 17, 2010 pm30 12:39 pm 12:39 pm

I don’t, I just posted the answers I got, and think are right, for m/c. For the short answers I’m confident they are all right.

June 17, 2010 pm30 12:40 pm 12:40 pm

First of all, call up the school to see if you can get your raw score (or get your parents to do it).

Second of all, Brooklyn Studio put the raw scores (see nylearns.org/pcuoccio if you want to see how many people flunked).

Best of luck to all,
Mike

June 17, 2010 pm30 2:05 pm 2:05 pm

Umm for m/c number and 21 i had a question. For number 21 wouldn’t the more negative the number the more it would show a negative correlation?

June 17, 2010 pm30 6:28 pm 6:28 pm

You’re correct, however the correlation coefficient cannot be lower than -1 or higher than 1, making -.89 the correct answer. (I’m assuming you chose -1.07?)

June 17, 2010 pm30 3:37 pm 3:37 pm

Is there anywhere where I can find the geometry regents answers from todays test?

June 17, 2010 pm30 12:38 pm 12:38 pm

bro i hope ur right cause most of my asnwer match ur thank you, i was so worried but u kinda of cheered me up

June 17, 2010 pm30 12:41 pm 12:41 pm

Starting at which number were the questions worth four points?Was it 36 or after that? Thanks

June 17, 2010 pm30 12:44 pm 12:44 pm

1 – 27 = 2 points each
28-35 = 2 points each
36-38 = 4 points each
39 = 6 points

Add them up: 2(27) + 2(8) + 4(3) + 6 = 88
Which is maximum 88 raw score.

June 17, 2010 pm30 12:47 pm 12:47 pm

What do you think a 70 in raw score would be worth?

June 17, 2010 pm30 12:50 pm 12:50 pm

If I had to guess 85 – 88.

June 17, 2010 pm30 1:03 pm 1:03 pm

a 70% if that is what you are saying would be a 62/88….not a 85/88

June 17, 2010 pm30 1:05 pm 1:05 pm

She asked for Raw score 70 equaling what % of a grade, not the other way around. And besides, she can’t even know her % grade because a conversation chart isn’t even out yet.

June 17, 2010 pm30 1:06 pm 1:06 pm

Nvm I was wrong, I re read it yes your right, sorry, it would probably be worth 55-60.

June 17, 2010 pm30 1:14 pm 1:14 pm

Im starting to question if u go an 88 on that test raw score wise, it seems like u cant do a simple proportion from ninth grade.

..

June 17, 2010 pm30 12:48 pm 12:48 pm

wow alot of ppl failed on that website with the raw scores

June 17, 2010 pm30 12:59 pm 12:59 pm

i like what the teacher said
“Congrats to those who cheated and passed, i am proud!!”
lmfao

June 17, 2010 pm30 12:59 pm 12:59 pm

for #7, does order matter when placing the cameras into box a?

June 17, 2010 pm30 1:02 pm 1:02 pm

Number 7 I wasn’t sure actually between 20 C 3 or 20 P 3, however I don’t think order matters, so it’s 20 C 3. (Choice 3) I later asked a couple of my friends, and they proved to me both through just thinking about it, to mathematical formula why it’s a combination. So the answer is (3) and order doesn’t matter.

June 19, 2010 pm30 8:33 pm 8:33 pm

Its 20 C 3 because even if you put camera 1, then 2, then 3 in a box, its the same grouping of cameras as if you put camera 2, then 3, then 1 in that box, so order doesn’t matter.

June 17, 2010 pm30 1:10 pm 1:10 pm

Should we go up to New York State and demand the conversion chart.

June 17, 2010 pm30 3:53 pm 3:53 pm

Given how poorly everyone did (well, not everyoen but this IS aMERICA where we talk about the majority), I think it is best to get on the good side of the board of regents.

Be patient; they’re trying to figure out just how low the cut-off should go (without angering the teachers like theyd id w/ algebra in ’08 by making the cut-off a 30).

This test was out of 88, so feel free to speculate and analyze; but patience is a great virtue.

We took the test, but the real test — it seems — is that of our patience.

Best of luck to all.

June 17, 2010 pm30 3:56 pm 3:56 pm

The conversion chart is NOT based on any proportion.

It’s not like 70 out of 88 is equal to x out of 100.

Generally speaking, it’s possible for the Board of Regents to curve up or down (meaning that 1x could be a 98) or a 30 could be a 66.

you are mistaken, Boris.

June 17, 2010 pm30 5:04 pm 5:04 pm

how is boris per say “mistaken” he simply made a humorous comment….

June 17, 2010 pm30 1:12 pm 1:12 pm

does anyone have an idea of what a 79/88 would convert to?

June 17, 2010 pm30 1:18 pm 1:18 pm

its a 90% raw score wise you simply divide (79/88) im kinda scared that some of you kids cant do math lol. We still dont know the scaled score because the bastards up in albany wont give us a converstion chart at the moment lol

June 17, 2010 pm30 1:49 pm 1:49 pm

i know it converts to 90%. im talking about what the raw score would convert to bc i think it could range from a 90 to 93 so i was asking for an opinion…

June 18, 2010 pm30 1:05 pm 1:05 pm

I’m in the same boat as you; 79/88 should translate anywhere from a 90-92 in terms of a scaled score.

June 17, 2010 pm30 1:38 pm 1:38 pm

a 70 in raw score would for sure not be a 60 anything. jd2718 posted in a different post earlier that a 90 would be anything from 70-78 points out of 88. so even if it wouldn’t be a 90 it wouldn’t be a 60 for sure. please explain your logic?!

June 17, 2010 pm30 1:46 pm 1:46 pm

ok first of all you werent very clear (70 what?? jellybeans)
a 70 percent
a 70 out of 88
in what terms are u talking

June 17, 2010 pm30 4:01 pm 4:01 pm

Porgey, you are mistaken.

the person is saying if her raw score is equal to 70…

What do you think the phrase “raw score” means?

It means out of 88 (which is the maximum # of pts that one could have earned on this particular Regents) An 88 is a 100, so the person is asking you to speculate what a 70 will be when it is converted when the Board of Regents finally releases the conversion chart.

Juries have taken less time to convict people and send them to the electric chair than this Board of Regents i s taking to finally allay our fears and tell us whether we passed; I suppose it’s all for the best, though: they’re trying to decide just how low the cut-off should go.

June 17, 2010 pm30 5:07 pm 5:07 pm

ok you need to calm down

June 17, 2010 pm30 1:39 pm 1:39 pm

and i was saying if my raw score= to 70 what would the converted score, in your opinion be

June 17, 2010 pm30 1:50 pm 1:50 pm

thats an 80 if you divide (70/88) i think that would be like an 83-85 converted and whatever this jd guy says is probably wrong he is giving such a vast range hes saying that anywhere from 70-78 raw points would be a 90. being that 70/88=80% i highly doubt u would get a 10 point increase with the curve since your at the point where the curve isnt so big anymore
-took ap statistics

June 17, 2010 pm30 2:10 pm 2:10 pm

can someone explain number 24

June 17, 2010 pm30 2:17 pm 2:17 pm

To answer your first question, 21) is (2) because r is defined such that |r| </ 1, where +/- 1 would symbolize strongest, but going higher than that doesn't make sense.

24) Let theta = x
cos^2x – cos 2x
cos^2x – (2cos^2x – 1)
cos^2x – 2cos^2x + 1
-cos^2 x + 1

From sin^2x + cos^2x = 1
subtract cos^2x both sides

sin^2x = -cos^2x + 1

Thus answer is (1) sin^2 (theta)

June 17, 2010 pm30 2:28 pm 2:28 pm

he didn’t say it would be 70-78 points- he said it could be anywhere in that range, as seen from past curves. so Jami could be right and so can you and maybe its somewhere in the middle of you both- I’d say it would be an 85.
She said “What do you think a 70 in raw score would be worth” that sounds clear to me, Porgey. So why are you saying, “70 what?? jellybeans” if she said in the first question- raw score.
Sigh. Now i see why they say book smart doesn’t mean street smart :) some people have no tact. Okay, so you didn’t understand her question- no one said you have to answer it, and don’t cover your mistake by saying she wasn’t clear.

June 17, 2010 pm30 2:40 pm 2:40 pm

according to past math conversion charts:
int. alg. jan 09- 77=90 and 68=85
geometry june 09- a 77 raw= 90 and 71=85
geometry aug 09- 76=90 and 68=85
geometry jan 10- 77=90 and 70=85

the first number is raw=real according to those conversion charts. These should give a good idea of what a 90 and 85 would be in raw score points. So, although your 70 would NOT be a 60, it would be most probably 87

June 17, 2010 pm30 4:05 pm 4:05 pm

Nice try, AS.

But this is the 1st administration of the algii/trig regents, and you can NEVER, EVER use PAST conversion charts; it’s different every time.

Nice try, though.

June 17, 2010 pm30 3:31 pm 3:31 pm

Will there be the geometry regents up on this website ever?

June 17, 2010 pm30 3:59 pm 3:59 pm

for 33 can u have put the answer sin -60? which is the same thing as -3 radical 4

June 17, 2010 pm30 5:09 pm 5:09 pm

it was -rad3/2 but im pretty sure it asked for exact value so i dont think -sin60 would be valid, but since you know what ur doing youll only get like 1 point off for it

June 17, 2010 pm30 5:00 pm 5:00 pm

you can too base it on that somewhat. The curve doesn’t really help the higher scores by much, and this would be a good gauge

June 17, 2010 pm30 5:16 pm 5:16 pm

JMAP had this scoring sheet uploaded.. By “Math B 2010” are they referring to Algerbra 2/ Trig?

June 17, 2010 pm30 5:27 pm 5:27 pm

Sorry Max, That’s the conversion chart for the Math B regents. It was given for the last time on Tuesday. Algebra II/Trig probably won’t be posted until rating day on Thursday, June 24th.

June 17, 2010 pm30 5:23 pm 5:23 pm

what do you think a 74/88 would be worth?

June 17, 2010 pm30 6:07 pm 6:07 pm

i love how the geometry conversion chart has already been posted which was only finished about three hours ago -_-

June 17, 2010 pm30 7:48 pm 7:48 pm

That’s because this is not the first Geometry Regents. Last year it took a week or so to post the Geometry conversion since that was the first administration of the exam.

June 17, 2010 pm30 7:11 pm 7:11 pm

for the standard deviation question would i get any credit for putting 7.5 instead of 7.4?

June 17, 2010 pm30 7:49 pm 7:49 pm

Probably 1/2 Credit. (Was that the Sample Standard Deviation Value?)

June 17, 2010 pm30 8:20 pm 8:20 pm

Yeah Noel i dont think that all ur multiply choice answers r right….id say like about 5 r wrong…try rechecking ur answer for #6,dude!

June 17, 2010 pm30 8:26 pm 8:26 pm

sqrt (-300) =
sqrt(-1)sqrt(100)sqrt(3)
sqrt(-1) = i
sqrt(100) = 10
yielding 10i sqrt(3)
Which is choice (3) , I think the others are right also, which other ones did you have a conflict with?

June 17, 2010 pm30 8:22 pm 8:22 pm

I actually believe they are all right, comparing them to mine and others’. 6 he did right

June 17, 2010 pm30 8:26 pm 8:26 pm

i dont think soo…caz my math teacher allowed the kids at my school to see the actual answer booklet as soon as we finished the test….n i got #6 right…n i didnt get the answer he did! =P

June 17, 2010 pm30 8:28 pm 8:28 pm

What do you think the answer for 6 is then??
sqrt (-300) = 10i sqrt(3), choice (3), I don’t see how it can be something else. And what other ones were different?

June 17, 2010 pm30 8:45 pm 8:45 pm

That is correct. It’s the same answer I got. What could you have gotten? Noel’s work was correct, it’s squrt(-1 * 100 * 3) (-1 * 100 * 3 = -300), giving 10i squrt(3). Unless someone made a mistake on the answer key, in which case a lot of people are going to be very angry when they get their scores. (I might end up getting one wrong because of a scantron error, I’m not sure if people look over the MC after it’s graded by the scantron machine. But it wasn’t 6, it was 11, in which I missed the negative sign in the exponent the first time I did the problem.)

June 17, 2010 pm30 8:26 pm 8:26 pm

…but i will say that all his short answers r correct tho!

June 17, 2010 pm30 8:31 pm 8:31 pm

I think the others are right too… unless you can offer some strong mathematical proof against them.

June 17, 2010 pm30 8:36 pm 8:36 pm

well another one that was different for #25 u put 1 but i put 4?

June 17, 2010 pm30 8:41 pm 8:41 pm

It’s an arithmetic series.
The first term is 1
and it goes 1 + 3 + 5 + 7 + 9 + …. + 39

The formula would be
Tn = T1 + ( n – 1) d
T n = (1) + (n-1)2
Tn = 1 + 2n – 2
Tn = 2n – 1
or 2k – 1 as they said it, so that leaves us with choice 1 and 4
Now it’s choice 1, because the top number represents how far it goes.

To find where 39 is,

39 = 1 + (n – 1) 2
38 = 2n – 2
40 = 2n
n = 20

Thus 39 is the 20th term

So the answer is choice (1)

June 17, 2010 pm30 8:47 pm 8:47 pm

Again, Noel is correct. That’s what I got for number 25, and it looks correct on analysis.

June 17, 2010 pm30 9:00 pm 9:00 pm

it was so freakin east
but i need to no the answers!

Boys and Girls!

Do I need to remind you to play nice? Apparently yes.

I’m temporarily closing commenting, while I write a note with some rules, and delete the unnecessary (and unuseful) bickering and snickering and name-calling and insulting.

When I open back up (in an hour or so), please, comment on the exam. On the problems. On the test writers.

But not on each other, right?

Thanks!

June 18, 2010 am30 12:24 am 12:24 am

hey can u post up the list of the short answers too pleez

June 18, 2010 am30 12:25 am 12:25 am

…sorry i should be more specific…i mean the original short answer questions!

• June 18, 2010 am30 12:30 am 12:30 am

They are a pain to type, and only one per page, so I’m not taking pix.

If JMAP doesn’t post them tomorrow, I’ll retype them.

Hey i no the conversion charts arent out yet…but if someone had to take an educated guys…what do u think a 66/88 on this regents would be!….as a scaled score!!!

June 18, 2010 am30 12:38 am 12:38 am

83

• June 18, 2010 am30 12:49 am 12:49 am

If passing is 49 and mastery is 73 (admittedly, those guesses are on the tough side), 66 would yield a 79.

You can play this at home. Enter the following points in your calculator: (0,0), (pass,65), (mastery, 85), (88,100) and then perform a cubic regression. That’s how the state sets the scale.

If passing is 47 and mastery is 70, 66 gives an 82.

If passing is 44, but mastery is 74, (low pass, high mastery), 79.

June 19, 2010 pm30 12:53 pm 12:53 pm

Where would you predict they set the mastery? I understand you can’t be really accurate, but that’s what’s going to destroy my score. Changing the passing doesn’t really help me at all, because my raw score is somewhere between 74 and 80 and I need at least a 90 or my parents will kill me…

June 19, 2010 pm30 1:28 pm 1:28 pm

Do you think it would be feasible if they set them it as low as 64/65, considering that the mastery value for the June 2010 Math B’s (from looking at the conversion chart) seems to have been 70 and considering the fact that that exam has been administered for years now?

June 18, 2010 am30 12:44 am 12:44 am

thanx!

June 18, 2010 pm30 1:03 pm 1:03 pm

My teacher told me that I got 79/88 raw score, which should translate from anywhere from a 90-92 in actual score.
Yes, I’m so proud of myself.

June 18, 2010 pm30 2:37 pm 2:37 pm

Noel, are you saying that you got an 83? If so I am sincerely sorry. I know what its like to think that I did incredible on something only to find out that I just did great. Nice job, Nate. Mike, what is your raw score? By the way, Porgey, it’s “per se”. I’m not trying to put you down or be a jerk. I’m just letting you know for future reference. Also, to those who have been saying mean thins about Albany: Taking one’s time does not make one a bad or mean person.

June 18, 2010 pm30 2:38 pm 2:38 pm

My bad, Noel. I didn’t see the other post. I know what you meant now. Have you found out for sure what your raw score is?

June 18, 2010 pm30 2:57 pm 2:57 pm

Why is it a cubic regression?

• June 18, 2010 pm30 3:01 pm 3:01 pm

Because a cubic can be fit exactly to four points (ie, I can make it work without regression… but if you use the calculator, r = 1, a perfect fit)

Is that a good reason? Absolutely not. They could use three line segments.

In fact, if you look at the Geometry conversion chart, 71 is 85 and 86 is 100, but the scores do not go up one point at the time. Bizarrely stupid, don’t you think?

I just don’t think Albany is good enough to make tests.

jd

June 18, 2010 pm30 3:09 pm 3:09 pm

Thanks for the explanation.
I don’t see a need for a curve at all.

June 18, 2010 pm30 6:32 pm 6:32 pm

“I just don’t think Albany is good enough to make tests.”
I want to quote this somewhere. (outside this comment)

I definitely agree. I had been worried about this test, but I seem to have done well on the M.C. The World History regents was a joke, and the chem regents ended up being harder than I expected. (From past tests. This year’s regents in chem had around 10 questions with traps that I saw) The A2/T fall sampler didn’t have that much correlation with that actual test, and although it wasn’t hard (for me), that was only because I was worried so much about it. (I even made a study sheet on the computer, which I almost never do. (a collection of useful facts that weren’t on the ref. sheet. (which I’d be glad to share if anyone wants it. It’s still on my computer.)))

June 18, 2010 pm30 7:08 pm 7:08 pm

Anon, I would like to see your study sheet.

I have created a temporary e-mail address — anonymoussir16@yahoo.com — so please send it there as soon as you can.

Thanks so much, and good luck.

P.S. There were certain formulas that were not given on the ref. sheet, and i found several sources off of which to study them. I’ll be glad to share them with you if you want, but in a private forum.

Also, note to the maker of this blog: Please delete this comment, b/c I do not want anyone spamming me. I am sharing my e-mail address b/c I realize that the only way to read formulas is in MS Word; keyboard characters alone do not allow one to read mathematical formulas.

• June 18, 2010 pm30 10:39 pm 10:39 pm

Do you mind sending it hear? it is my name at gmaik dot com, with an obvious typo

jd2718

June 19, 2010 am30 12:12 am 12:12 am

I sent both. It took some frustration because Gmail seems to have an attachment problem, but I managed to get both emails sent without an error. (Mike’s took 3 tries, and JD’s managed to cut my internet connection, forcing me to reboot once.)

If anyone else wants it, I’ll upload it to my website instead of sending an attachment, and email you the link.

The sheet saved me a few points on the regents, and although I might have missed some things, and it is basically a compilation of random facts that I forgot or thought I would forget otherwise, but it helped remind me of things I did once then forgot. (such as completing the square)

PS: I’m not the same person as AnOn or as anon student. (I think both were used to distinguish from me.)

June 18, 2010 pm30 10:00 pm 10:00 pm

For number 17, are you sure it’s 1 and not 3?

June 18, 2010 pm30 10:08 pm 10:08 pm

Yes, it’s 1. Check the point (0,0) in the equation, and it works.

And to Mike, I sent it to you. I’m sorry about the 3 emails, but I got an error message on the first and second time, so I sent it a third time. Gmail apparently hates .jpg files.
And there is no reply button on your comment, so I’m replying to the next comment I saw.

June 18, 2010 pm30 10:45 pm 10:45 pm

can anyone post the integratd algebra regents answers or questions?

June 19, 2010 am30 11:29 am 11:29 am

My teacher said I got a 80 on this !! I am so happy!!

June 19, 2010 pm30 12:12 pm 12:12 pm

how bout algebra

June 19, 2010 pm30 8:44 pm 8:44 pm

For number 18, I chose 1, which you chose, but there has been a lot of talk among my friends about 6 working in the check, having it come to be:

I said it didn’t work, how bout you?

June 19, 2010 pm30 9:00 pm 9:00 pm

No.

6 has to be rejected as an extraneous solution.

I know what you’re trying to say, that radical 9 CAN be -3, but — in this case — it doesn’t work that way.

June 19, 2010 pm30 8:46 pm 8:46 pm

For the short answer question where it wanted the probability to the thousandth place, do you think I’ll lose points for answering 16.729% ?

June 19, 2010 pm30 8:47 pm 8:47 pm

For the question that asked for the probability to the nearest thousandth, do you think I’ll lose credit for writing 16.729% ?

June 19, 2010 pm30 10:52 pm 10:52 pm

@Anonymous, I don’t think you should lose points for 16.729% because it is considered a probability rounded to the nearest thousandth. I’m a teacher and a number of students put that as an answer and the math department agreed to give students full credit for that response.

June 20, 2010 pm30 3:34 pm 3:34 pm

you will lose 1 pt unless your teacher grades the exam loosly. which is what we must all keep in mind. Proability should be expressed as a decimal, but if your teacher allowed you to usae % during the year they may allow it on the regents.

June 19, 2010 pm30 10:52 pm 10:52 pm

@Anonymous, I don’t think you should lose points for 16.729% because it is considered a probability rounded to the nearest thousandth. I’m a teacher and a number of students put that as an answer and the math department agreed to give students full credit for that resp

June 20, 2010 pm30 2:11 pm 2:11 pm

Lets say I recieved a 37 raw score, wouldn’t I have a shot at passing because the first Math B regents raw score to pass was a 37? Also they are similar in test, I am probably mistaken but someone please let me know if I’m right.

June 20, 2010 pm30 8:02 pm 8:02 pm

yes you have a shot for 2 reasons…first that may very well be the cut off for passing, you can never really tell what the state is going to do. second, lets say the cut is 40, your teachers have to regrade any exam that is above 60% scaled to see if they can find it points to get to a 65. if they graded a couple of your problems tougher, they may be able to squeak a few more points out of the test.

June 20, 2010 pm30 3:13 pm 3:13 pm

Isn’t number 19, 3, because when u plug in radical 9 it gives u positve or negative 3 and thats why 6 works as well?

June 20, 2010 pm30 3:34 pm 3:34 pm

i mean # 18

June 20, 2010 pm30 3:41 pm 3:41 pm

the correct choice is 1. you cannot solve the problem that way. check it by graphing both equations into your calculator.

• June 20, 2010 pm30 4:13 pm 4:13 pm

Rule of thumb: When the radical is printed on the page in front of you, it means the principal square root (positive value) only. When you are doing work, and add your own radical symbol, then you need to consider both values (you are really asking the question, when I square what number will I get the thing in front of me).

So solve for x: $x^2 = 100$, x could be 10 or -10, but
Find the value of $\sqrt{100}$, that’s just 10.

June 20, 2010 pm30 7:41 pm 7:41 pm

Hey if the cut off score is gonna be in the 3o’s like some people are predicting then wouldnt something in the high 60’s be a 90!….not the 80’s!!!

June 20, 2010 pm30 7:58 pm 7:58 pm

the curve doesn’t help the higher scores very much, they have to develope the curve for both passing and mastery. if your in the high 60’s great job, but until the 24th when the conversion chart is released anything anyone tells you is a guess.

June 20, 2010 pm30 8:53 pm 8:53 pm

Just out of pure interest and curiosity, I ran a few points in a cubic regression on my calculator and came up with a conversion chart. I set 40/88 as a 65 and 67/88 as an 85. Might be a bit low, but considering the difficulty of the exam, I think it’s fair. (R = Raw Score, S = Scaled Score) Have fun. :P

Also, please note that this is NOT the real conversion chart. This was just for fun.

June 21, 2010 am30 10:17 am 10:17 am

For the asymptote question…what did it mean by write the equation?

June 21, 2010 am30 10:22 am 10:22 am

y = 0.

The equation of the asymptote, the line that gets closer and closer to the x-axis but never touches it.

Ever hesr of, “write the equation of this line given its slope and y-intercept”?

y = mx+b

Well, that’s an equation.

In this case, they asked for the equation of the asymptote. I think that what threw off you (and most students) is not knowing the meaning of “asymptote”; if you knew what it was, you would probably have no problem writing the equation.

Best of luck on the conversion chart,
Mike

June 21, 2010 pm30 6:21 pm 6:21 pm

for #37, how are we supposed to find the four solutions?

sinx=sin2x

i only got two, 60 and 360. i can see how 0 and 180 make sense, but how can you show that algebraically? and how many points out of 4 do you think i’ll get???

June 22, 2010 am30 1:13 am 1:13 am

First, 360 doesn’t work, since it was in the interval of greater than or equal to 0, but only less than (and not equal to) 360.

Second, when you have Sin X = 0 and CosX=1/2, you don’t need to show anything else. It’s assumed that you know that when SinX = 0, X =0 and 180, and when CosX = 1/2 X = 60 AND 300.
If you’re wondering why X=300, it’s because 60 is just the reference angle. Cosine is positive in the first and fourth quadrants, and 300 is in the fourth quadrant. (360-60 (ref angle) = 300)
If two angles have the same reference angle, then the absolute value of Cos, Sin, and Tan are equal.
In comparison, in the second quadrant, Cosine is negative, so where the reference angle is 60 (120), cosine equals -1/2. (note the negative sign.)

I aced the Alg2/Trig regents because my teacher told the class to have their parents buy and use the Westsea Publishing NYS regents review workbook for Al2-Trig for homework every day.

http://www.westseapublishing.com

check it out. Uae it for summer school.

June 23, 2010 pm30 2:51 pm 2:51 pm

i got a 72 out of 88.( which is an 81.8 so 82) what do you guys think are the chances of that being curved to an 85 ?

June 23, 2010 pm30 3:13 pm 3:13 pm

Nicci—You’ll probably score between an 85 and an 88 depending on the curve. It comes out tomorrow; you can check online!

Good luck!

June 23, 2010 pm30 3:28 pm 3:28 pm

i hope its a good curvee. and thankss! (:

June 23, 2010 pm30 4:26 pm 4:26 pm

you may end up from anywhere from 80-90 if it’s a really good curve (hoping…)

June 23, 2010 pm30 10:11 pm 10:11 pm

i was so thankful that the test was actually not as hard as i expected. supposedly a lot of people failed but imagine it was actually way more difficult. oh godd!

June 24, 2010 am30 10:41 am 10:41 am

omg! the curve is insanee! 91% thank you NYS (:

June 24, 2010 pm30 12:14 pm 12:14 pm

the conversion chart is up, its amazing, im 100% sure i got a 99

June 24, 2010 pm30 3:57 pm 3:57 pm

I got a 98….the curve was sick. If it was like the chemistry curve, i would’ve gotten like a 93

June 24, 2010 pm30 5:59 pm 5:59 pm

When i say the curve i was like….dammmmnnnnn……this thing is awesome!

June 24, 2010 pm30 6:00 pm 6:00 pm

yea this is like the first time that NYS has actually helped the kids who have gotten higher grades

but i’m sure there are a lot of people who were hoping for passing to be at a much more accessible raw score than 46

i mean for this year’s integrated algebra the passing raw score was 30 out of 87 so people who scored lower on this test are probably not very happy

but i’m fine with it cause i got a 97% with an 81 raw score

June 24, 2010 pm30 11:40 pm 11:40 pm

Woot!woot!…i got a 86% on the alg.2/trig regents!!!
