October 2009 SAT II - Math Level 2

<p>what was the prime number question! was the answer choice E?</p>

<p>^ It was 8; not sure what letter that corresponded with.</p>

<p>okay well i guessed and checked and got 3.8.</p>

<p>And I can’t believe i forgot the 1 + tanx^2 = secx^2 identity! All those trig classes gone to waste!</p>

<p>nvm i got it wrong.</p>

<p>what would the possible score be for 5 omitted and 1 wrong?</p>

<p>im hoping 800… todays test was a little hard…</p>

<p>the wording of that profit questions where the answer was 30% made NO sense, but I still guess 30%. @monstor344, if you ever forget an identity just remember sin^2 + cos^2 = 1, and you can derive the others by either dividing by sin^2 or cos^2. </p>

<p>hope i got 800 and never have to take that again…</p>

<p>was question 47 e?</p>

<p>do you remember the question and what e was?</p>

<p>I kind of lost all my answers in my head for Math 2 after Chem… all I remember was that the Cone one was 4.8.</p>

<p>According to the Blue Book:</p>

<p>-6: 800
-7: 790
-8: 780
-9: 770
-10: 760</p>

<p>I’m so stupid, I skipped the 30% profit question because I didn’t get the wording, but now it seems so easy. And if I’d realized that the 0.8 question was a unit circle, it would’ve made life so much easier.</p>

<p>^ I guessed 30%. The other choices were illogical, unless I read the question wrong.</p>

<p>Hey…do you guys remember the question where it asks what is the biggest value of x in which f(x) = 5…and all the possible x values plugged in…none equalled 5… exactly
also did anyone write down 5.6 as the biggest zero</p>

<p>did ANYONE get the “n number of judges” question? </p>

<p>that just made no sense to me…I understand the principle of the mean, and I understood all those types of questions in the practice tests. thats the only one i omitted</p>

<p>The biggest zero one was like 2 something? Was there even a choice for 5?</p>

<p>I put 5 judges because whatever the non-integer score * 5 was an integer.</p>

<p>That reminds me, was the “Which of the following, for x > 2, is NEVER an integer:” x / (x-1)</p>

<p>It was 5 judges, you could plug an check. The only ones that worked were 5 and 15.</p>

<p>mrcool: It was 5 judges. If one of the scores was 5.4, try to get that average with n = 3 judges (5 + 5 + 6) / 3 = 5.3333 so it can’t be three judges. Try five judges (n = 5), and I randomly picked the values (5 + 5 + 5 + 6 + 6) / 5 = 5.4. Same goes for an average score of 6.0</p>

<p>I think we’re talking about different questions…
there was this equation like x to the 4…and it asked for the largest zero…my calculator was between 5.5 and 5.6…but i didn’t have time to see which one it was close to…to the nearest tenth…</p>

<p>The super long x^4… equation had a zero at whatever the largest answer choice was, I think. It was 2 point something. solve function ftw</p>
