As the NYS regents examinations are coming close, students are putting in their final preparations, including me. I’m taking Global History Chemistry and Geometry, Tuesday, wednesday and Thursday, respectively. Any quick ideas? words of encouragement?
And for those of us who don’t have regents its finals. HELP! I’ve been studying for hours!!!! What about kodesh subjects such as chumash, halacha, etc.?
The accompanying table shows the average salary of baseball players starting in 1996. Using the data in the table, state the linear regression equation with the coefficients rounded to the nearest hundredth.
Number of Years Since 1990 Average Salary (thousands of dollars)
6 1263
7 1472
8 1516
9 1864
10 2067
11 2378
State the exponential regression equation with the coefficient and base rounded to the nearest hundredth.
Use your written regression equations, by how much does the exponential model exceed the average salary in 2010 predicted by the linear model, to the nearest thousand dollars?
I have typed the numbers into my calculator, and followed all the proper instructions for finding the linear regression equation, yet I am still getting the wrong answer. The answer should be y=204.61x+7.82, yet my answer is y=220.228x-111.942. As you can expect, my other answers are wrong too.
I also tried to do that example, and i got the same answer as you….
i think the book may be wrong.
GOOD LUCK
Heh… I do all my regression analysis work on computers these days.
Back when I took the regents, I had to chisel the answers onto stone tablets.

mathhelp:
I just did the calculations as well, and I got the exact same answer as you did. Are you sure that one is not correct?
Otherwise, I don’t know.
Good luck!
Note that the salaries are written in THOUSANDS, you have to add three zeroes at the end when entering it….even so my decimal is three places off I’m not sure why that is though

actual regents can be found if you google (subject) _____ nys regent
good luckkk
Oh, woops I read your post wrong – I got the right answer the first time I did it but then the second time when I put it into thousands I got it wrong – and now I got it wrong again
Boy am i glad im done and over my regents! Quick tip-by multiple choice and youre really stumped don’t choose any answer that has “always” or “never”- they are usually wrong. If its a math example don’t choose the highest/lowest number. Take a stab at the in betweens. Hatzlacha rabbah!
To add to what blinky said, if on the multiple choice you’re stumped and the past few questions were all a/b’s then chances are it will be c or d.
blinky, so interesting about that, I’ve usually found that in cases where they give an “all of the above/none of the above” option, that was the correct one.
Hatzlacha Rabbah to all regent takers! Remember you just need to pass and aside from the fact that there is usually (not always) a good curve, there is a certain amount your marker can do for you. Dont worry, say a Perek of Tehillim before you start and you’ll be good to go.
The Wolf, I knew you were old but not THAT OLD!!!
Why do yeshivos even allow kids to take regents. you dont need them to graduate high school. You can get a nonregents diploma without them. The regents are such bittul torah.
Mosherose? Just wondering…the CR is gemara or mishnayis? I’m just imagining that if ur on here then it must be Torah…
“the CR is gemara or mishnayis?”
Neither. But since most of the topics are torah-related its not too far from learning. But anyway I learn all day and my rosh yeshiva agreed with me that I dont have to spend every minute learning at night if Im busy with it during the day and if wwill affect my learning during the day.
The Wolf, I knew you were old but not THAT OLD!!!
Heh. It cost my high school $48.75 to mail my diploma to me… because it was on a stone tablet. 🙂

why are high school kids posting on this site?
I didn’t know that we have to show i.d. when we sign up
“blinky, so interesting about that, I’ve usually found that in cases where they give an “all of the above/none of the above” option, that was the correct one.”
Kapusta-i ddn’t say that. i was trying to say that any answer that is final such as always, never… are usually incorrect as there are always exceptions to the rule. I do agree with you that none/all the aboves are pretty much correct.
For all those of you who are flipping out that there are HS kids on here-that’s why you should watch what you say. Not only that, anyone (and you never know who) could read your post even if they’re not a cr member. Now, when signing up it never said that you have to be over any age.
i did. was it just me or was it extremely hard?? i did all the regents from the past 3 years and none of them even compared to this. how about you?? i cant wait to see what my geometry one will look like…
blinky: gotcha! thanks for clarifying. 🙂
To add my two cents on the age thing (and I’m probably gonna regret this later) but I dont really think its fair for anyone to make rules for other people, especially so if they dont even know each other. As someone recently out of high school, the CR is not all that bad.
(yes, mods, you can give yourself a pat on the back now)
yea even my teacher said multiple choice this year was nuts… anyway no amount of practice or help will make me understand any form of math. i have been practicing like crazy the past few weeks but i still dont feel prepared for the geometry regent. and my math teachers are anything but good… sigh
be confident, the geometry regent is not that bad if you know your stuff.
did anybody take the trig regent today?
do you think it was easy or hard?
i found it to be hard.
Yea thanks, but what if you DONT know your geometry stuff? am i doomed? my regent is on thursday and i do not feel prepared even though i studied for weeks. and ive heard that its supposed to be difficult. what do i do???
I took trig it was pretty easy. The probability question with the mens club and the vests is the only thing I for sure got wrong, I wrote my answer as a fraction instead of a decimal like they wanted.
With the correlation coeficient what was the answer – I wrote -.89 cuz I don’t think that you can go over 1 or less than -1.
Anyone remember what they got for the area of the paralellogram I know that I wrote 603 square feet
….and my friend is convincing me that it’s wrong
toomuch00, these are my observations of the Geometry regent. (Anyone is free to argue with me.)
1) Teachers spend 1/2 the year or more on proofs. Proofs is usually about 6 points on the regent – one multiple choice question and a long answer question.
2) Many of the multiple choice questions are based on information that is taught in grades 7 – 9.
3) Often (at least once per regent), one question provides the students with the necessary information to answer a different question.
4) The rubric is quite rediculous. (Though it’s not as bad as the Algebra 1 rubric.) You can get less than 50% correct and still pass the regent.
5) The best way to study is by doing regent questions. You have another 24 hours or so – so get to work! Do the sample tests and old regents. Use your Barron’s book (I’m assuming you bought one) and jmap.org. No matter what the results are, at the end of the day you want to know that you tried your best.
Good luck!
im glad when i took my 9th and 10th regents they where really easy i guess i got away with it;)
you must get a 65 or higher on five Regents Exams: Integrated Algebra (or Math A), Global History and Geography, U.S. History and Government, Comprehensive English, and any one science regents. To receive an Advanced Regents Diploma, you must also pass an additional Regents science exam, (Earth Science, Chemistry, or Physics), an additional math exam (Geometry, Algebra 2/ Trigonometry, or Math B), and a foreign language exam.
simcha man: what is a “rubric”? is that like a curve?
yes the rubic is the curve, and some time all you need to pass is about 30-40% raw score.
toomuch00, here’s a link that might help you. http://jmap.org/JMAP/RegentsExamsandQuestions/3-AdobePDFs/OriginalExams/Geometry/0110ExamGE.pdf
It’s this past January 2010 Geometry regent with the answers and the rubric. After completing the practice regent, add up your points – this is your RAW SCORE (the highest possible is an 86). The look at the rubric on the last page. Find your RAW SCORE in the white column and check the corresponding shaded cell for your SCALED SCORE. The scaled score is the only score that will show on your report card and transcript.
Good luck!
If not for regents, I would have actually had to do some work in high school. For example, I had failing grades in chemistry throughout the year (I’m talking 30s), then I learned the material in about 3 weeks of bathroom and spare time reading and got 95 on regents and passed the course. (anti-semite still gave me only a 65 on report card). Similar story with math 3.
Really, it makes me wonder whether with the right teachers I could have come out of high school with a college graduate’s knowledge of all the major maths and sciences.
Mathhelp,
I know it is too late to help, but I also got y=220.228x-111.942.
I have both a B.A. and and M.S. in Applied Mathematics and a Ph.D. in Biostatistics. This despite the fact that my only “B” in a math course between grades seven and twelve was in a probability and statistics course. Critical thinking is far more important than remembering formulas in statistics; in fact I don’t remember most of the basic statistics formulas and I am now a full Professor of Biostatistics at a major medical school! (And I have no idea why they are teaching exponential regression in high school; it is something usually taught to graduate students.)
Thanks to everyone who replied. The general consensus seemed to be that the book was wrong, so I didn’t worry about it on the regent. In the end, however, there weren’t any linear regression questions on the regent.
R.L., the area of the parallelogram was 604 feet squared.
I have another question, this time in US History. I guess my user name is no longer appropriate.
Many opponents of the new deal programs claimed that these programs violated the American tradition of?
(1) welfare capitalism
(2) governmental regulations of business
(3) collective bargaining
(4) individual responsibility
The correct answer is 4, verified a number of times. But why isn’t the answer 1? Can someone please explain to me the reasoning behind this answer?
Thank you.

Instead of giving you the answer, I’m going to encourage you to think it through.
What is welfare capitilism? And why do you think it conflicts or aligns with the policies of the New Deal?
The Wolf
Wolf, that’s precisely what I am uncertain about!
Well, spell it out here. What do you think welfare capitalism is? What was the New Deal? Then analyze. I’ll help you along…
