Official December SAT II Math 2 Thread

<p>wait, you guys sure we can talk about the answers?</p>

<p>Hopefully you'd still be in the 700+ range, but I'm not entirely sure. Hmm, so about the weird operations question.. Eh?</p>

<p>It went a hell of a lot better than the last time. I left 4 blank, and I think I got all the rest right, though I probably missed like 1 or 2. Hopefully I'll just get an 800, or extremely close to it.</p>

<p>How did you do that problem with the books and the standard deviations? I thought it was just .1 * 4 books * 4 packages = 1.6 lb, but that wasn't one of the choices.</p>

<p>what was the answer for 6n^2 / 3n not equal to 2n.</p>

<p>That standard dev. is just .1
It doesn't change when you add to all of them equally.</p>

<p>Unlike the mean, the standard deviation does not get affected by a constant increase in all values.</p>

<p>WOOHOO FOR AP STAT!</p>

<p>was the last question (tan..blah) c?
ㅣsecl was it?</p>

<p>i thought it was harder then the practice tests I took. I left like 6 blank and was rushed fro tiem so i think I screwed up on a bunch</p>

<p>IS the SAT2 college board book curve accurate?</p>

<p>Yes, the last question was abs(sec x)</p>

<p>And for the horizontal parabola I got x = -t2 - 1 and y = t, which was choice E.</p>

<p>I think I totally screwed up... over 10 blank, a few wrong... that's what I get for having a lame teacher for 4 months during math III last year... and probably not studying very well.. hah :/</p>

<p>yeay~ easy for the last one.</p>

<p>and for the probabity questions.</p>

<p>that lab question, was it xCy times yCz ? (C,D)? not sure</p>

<p>and the long distance question, was it just multiplication? (9/2)?</p>

<p>Yeah it was 16C4 * 4C1 which was 7280</p>

<p>What was the long distance question?</p>

<p>there were 3 probabilites, and 1 vector, 3D, standard dev.</p>

<p>is that normal? anyone know?</p>

<p>Yeah thank GOD I reviewed standard deviation on the car ride there. Otherwise I would've been so confused.</p>

<p>There were no sequence/series questions! Boo!</p>

<p>theoneo/ you know that probaility question about someone making call either long-distance or local? and asking what is prob. that he's gonna make long and local call?</p>

<p>It couldn't have been 1/3 x 2/3 = 2/9.</p>

<p>That is WAYYYYY too simple for the second to LAST question.</p>

<p>I put 4/9...because then, I wouldn't have left like six blank in a row (the last six) lol. I wish it's right because I left 14 blank and if I even get a few wrong, there goes the score..under 700.</p>

<p>Ohhh yeah I got 2/9, too.</p>

<p>Eddieee/ maybe that was the trick. making you to think that it's too easy for the second to last question. kk maybe not</p>

<p>"There is a 2/3 chance an incoming call is Local.
A 1/3 chance that it is international.
If two calls are independent events, what is the probability of getting a local and international call?"
2/9, 4/9, 1/2, 5/9, 1</p>

<p>I think those were the choices. (I may have mixed up the assigning of 1/3 and 2/3 to local/int'l, but it's still 1/3 and 2/3 and it won't matter). </p>

<p>Come on you CC MATH FOLKS!</p>
