October 2011 - Math Level II

<p>The test wasn’t too hard, so the 800 curve will probably be 44-50, I think.<br>
I skipped 4, but I probably got 2 or 3 wrong as well.</p>

<p>@snigmgad99</p>

<p>Correct, that’s what I got too.</p>

<p>Hey, a ‘general question’ here.
Lets say youre trying to find the roots of:</p>

<h2>(x-3)(x+2)</h2>

<p>(x+2)
So can you cancel out the (x+2) terms or would that eliminate a root? Does this example apply to many situations?</p>

<p>Also, I felt the test wasn’t very hard, it was just a bit time consuming for me. Especially the question of sum > 5 from set of 0-9. I couldnt take the time to do that one.</p>

<p>i had it split b/w .8 and .9 and couldn’t think of how to solve it…until i got home. </p>

<p>haha and it took about 30 seconds. .9; im ticked i put .8</p>

<p>but yeah, there were a few i didn’t have the chance to do</p>

<p>Do you remember the absolute value questioN?</p>

<p>something like abs(3x + …)…</p>

<p>what did you guys put as the answer?</p>

<p>also, did you put I only for the -2 and 3 roots?</p>

<p>finally, did you say that 3x-4 = 0 or, it can equal 17??</p>

<p>^same. i felt some of the radian questions were a little different than past released tests. do you remember the answer choices for the sum >5 one?</p>

<p>edit: also curious on the absolute value one</p>

<p>same i just skipped because it would’ve taken too long</p>

<p>absolute value question = no zeroes/no solution. just graph them.</p>

<p>i said 17…</p>

<p>@lacamotif</p>

<p>1st question - it was 3 values
next q -yes
last q - it was 17</p>

<p>sum >5 question:</p>

<p>A) .9
B) .8
C)
D)
E)</p>

<p>shouldn’t have even considered C-E because all <.5</p>

<p>can anyone explain how to get 17? and i just did the probability question and got .79…so i woulda said B.</p>

<p>edit: wow that probability one didnt take too long to do -.-</p>

<p>46,48 and 49 were very time consuming. At least for me.</p>

<p>So what do you think where will skipping 3 and (just to be safe) 3 wrong land me?</p>

<p>Abs question, no solution.
4x-3=0 question, 17.</p>

<p>What did people get for the period question: f(x) = -1/2 for odd integers and = 1/2 for even integers?</p>

<p>It looked like a -sin curve, but I thought the period would be between 2 and 3, so I just wrote no period because it wasnt any of the answer choices.</p>

<p>^ I put in no period. Since the curve moves like (0,0) and then changes to a period between +1/2 and -1/2 which would normally have a period but I thought an anomaly will be the (0,0) point.</p>

<p>are allowed to be discussing?</p>

<p>@tizil, sorry what? I don’t really understand.</p>

<p>NspiredOne, embargo is lifted on discussion: <a href=“http://talk.collegeconfidential.com/sat-subject-tests-preparation/425654-important-embargo-sat-tests-discussions-may-2010-a.html[/url]”>http://talk.collegeconfidential.com/sat-subject-tests-preparation/425654-important-embargo-sat-tests-discussions-may-2010-a.html&lt;/a&gt;&lt;/p&gt;

<p>@tizil: isnt 0 even though?</p>

<p>I don’t think we can discuss specific questions yet-- just wait a few more hours guys!</p>

<p>I hope the curve is generous this time. I skipped five questions and ran out of time D:</p>

<p>0 is an even integer. That would make the graph periodic, no?</p>
