<p>yup~jansat i got the same ans as u for the abs value problem~</p>
<p>i got 599
the question asked for the maximum point
so i just took the derivative of the equation to get like -9.8x=-107
got x and then plugged that back into the original equation to get 599</p>
<p>jansat, I got that too.
Miao123, I think it was E. 2 is a prime number. I’m not sure</p>
<p>Sporty posted a good question in another thread, “can anybody tell me what they got for the question with the Roman numerals…
I. cos 2theta is greater than sin theta
II. sin 2 theta is less than…
III. tan theta is greater than sin theta.”
I was wondering about this one too.</p>
<p>I’m also wondering about the quadratic regression problem… if anyone is new to this thread and knows the answer to it, please share</p>
<p>jansat, i got the same
miao, i put 2 is a prime number.</p>
<p>gildedmushroom & mrdoodle65, yay i got 2 is a prime # too~
gildedmushroom do u happen to still have the lists of #s for the quadratic regression prob?</p>
<p>the answer to the roman numerals one you guys just mentioned is only II and III</p>
<p>i think you got the numerals messed up
I sin theta is greater than sin 2 theta, which it isn’t at all points from 0 to pi over two
II i forgot but it was right, trust me
III yeahh tan theta seems to always be larger than sin theta</p>
<p>i just got III for that</p>
<p>i got teo is prime also, does anyone remember the number question that was, the letter to that was E right?</p>
<p>and heres the list
0 1 2 3 4
1.5 22 32 34 20</p>
<p>Miao. the numbers for the regression problem were I think:
0, 1.5
1, 22
2, 32
3, 34
4, 20
credit goes to mrdoodle for remembering though… ahah
and I don’t remember what I put for that Roman numerals question with the 2theta and everything…</p>
<p>I know this is a stretch, but does anyone remember what #38 was? It was the only one I skipped and I forgot what the problem was…</p>
<p>Edit; Yeah jansat, the answer to the prime number question was E. 2 is a prime number</p>
<p>If you got 599 as well, then his equation is probably wrong. The choices were all between 1 and 6.</p>
<p>i got 5.2 for the quadratic regression</p>
<p>sry gildedmushroom, i don’t remember what that was.</p>
<p>but does anybody know if the scores can be curved so that our scores come out to be higher than the ones listed in the official collegeboard book.</p>
<p>b/c i’m thinking of cancelling my score since i already got over 700 and was striving for 800 but i don’t think that’s possible with 5skip and 3 wrong so far…</p>
<p>I got just three for the roman numeral one where like tan=-tan or something</p>
<p>What about the one divisible by 180…I think I got 30 for that one</p>
<p>@tuezmoi</p>
<p>^how did you get that</p>
<p>Yes, tuezmoi, I love you. I did too. Did you guess or did you work it out on a calculator or something?</p>
<p>i guessed rofl</p>
<p>the divisible by 180 one asked what number raised by the integer k would be divisble by 180</p>
<p>if you just plug all that stuff into the calculator</p>
<p>30 ^ 2 = 900 which is clearly divisible by 180</p>
<p>i think 599 is the answer to the physics question? that was E right, the highest point?</p>
<p>for the regression one… was 4.9 one of the answers? because i’m pretty sure that’s what i got</p>
