November 2012 SAT Math Level II Discussion

<p>Some answers I got:
1-cos theta
Abs(sec x)
7280</p>

<p>Could someone verify this?</p>

<p>YES I GOT ALL 3 lol</p>

<p>7280 was the 12 something, take 4 , and then 1</p>

<p>probability?</p>

<p>I can verify 1-cos theta and Abs(sec x) <— this was #50 I think :)</p>

<p>I can’t remember the last one</p>

<p>how did you guys get 4/9 for #49? was there a not I missed in the question somewhere? it was independent events both happening, was it not?</p>

<p>how bout #1… was 1 i think?
it was the hole… i got confused at first</p>

<p>Yea I got .1 or something. It was 1.1,1.1,1.3,1.3,1.3</p>

<p>o yeah its .1 nvm just checked my calc</p>

<p>you add 2kg to them all so 3.1, 3.1, 3.3, 3.3
still the same as 1.1, 1.1, 1.3, 1.3</p>

<p>1 wrong so far… still good for an 800 HOPEFULLY!</p>

<p>@IHateYouVergil It asked you what was the probability that ONLY if phone call was made in local or not locally. It was given 1/3 and 2/3 each. Both of them happening is 2/9. Both of them NOT happening is 2/9.</p>

<p>What did u guys get for this question
(6 triangle 4) (+) (5 triangle 3) = 2.5</p>

<p>i think triangle was / and + was *</p>

<p>x=x^2+bx+c</p>

<p>anyone?</p>

<p>What did you guys get for the height when it involved the sphere/cone and the volume was 1000?</p>

<p>@grape i put 2 not surue though</p>

<p>i just did like x^2+3x-x+2</p>

<p>random numbers for b and c</p>

<p>yea I agree</p>

<p>(6/4) + (5/3) = 2.5</p>

<p>What was y approaching as x approaches 3/2?
I put increasing infinitely</p>

<p>and then for the 3 numbers are consecutive… they can be divisible by</p>

<p>I. 2
II. 3
III. 4</p>

<p>i believe thats what it was and even though it might be wrong i believe i got I,II, and III</p>

<p>@GrapeIsGreat - same CHOICE E
i took AP calc Bc … love limits :)</p>

<p>I got I and II. 1x2x3 can’t be divided by 4.</p>

<p>Increasing without bounds were the exact words I believe</p>

<p>I said infinity @Grape</p>

<p>@olaolaolaola - o man i didnt catch that -.- F … did it say what MUST be true?</p>
