Nov. '09 - SAT Math Level 2

<p>I agree, i got like 99.999…</p>

<p>ax^3 + bx^2 question, was it option E or something</p>

<p>percentile was above 99.
Pretty sure… you use the 68-95-99 rule</p>

<p>Should have been choices I and III, so that might be right.</p>

<p>ugh i think i got -1… i think i circled wrong chioice because i had like 20 secs left when looking over the paper and i changed my answer choice, can anyone remember if it was E for I and III?</p>

<p>do u remember what choice one said?</p>

<p>what were I and III? I don’t really remember the answer choices</p>

<p>answer 1, i know silly lol :stuck_out_tongue: was 2^3/5 then there was the center of ellipse at (-2, 5) or (2,-5) something, then there was a question where the angle was like 29.3 or something, last 1 i got 99+, second last i got none, for the tangent question i got 3.14, umm cant remember many others</p>

<p>the second to last question was about the triangle.
I am pretty sure the answer was infinite.</p>

<p>The I and III question was the one with of x=2 and x=/2 for some equation.</p>

<p>Yeah, I got infinite too.</p>

<p>What was the answer to the trapezoid problem. It was question #19, with one side equal to 8, where you had to find the height.</p>

<p>weird, for that one i got only 2, because I was if x=/2 then some equation is not equal to eight, this is false because minus 2 worked, and then for II it was the converse, if a statement is false its converse it right, then III didnt work either for me. And as much as i remember the wording for the triangle one was how many noncongruent triangles can be formed, but since a<bsina there was no triangle possible, doesnt matter if its congruent or incongruent, no triangles could be formed at all.</p>

<p>it was like 8*tan 42 if im not wrong, in that one they gave the base length for no reason</p>

<p>DMOC’S OFFICIAL MATH II SAT REPORT!!!</p>

<ol>
<li>I got “no triangles” for the question concerning how many triangles could be made.</li>
<li>I got “Above 99th percentile” for the standard deviation question.</li>
<li>I skipped the “what’s the center of this ellipse” question. Only one I skipped. :(</li>
<li>For the question that had “which is the greatest value: cos 67, sin 67, etc. I chose the last choice.” Sec67.</li>
<li>For this question:</li>
</ol>

<p>I. If x^2+4 = 8 , then x=2
II. If x^2+4=/=8, then x=/=2
III. If x=/=2 then x^2+4=/=8 </p>

<p>It’s II only.</p>

<p>My only question concerning the test is … what the heck is the answer to the question that asked “if the average of this set is x^3, what is x?” Seems easy at first but I must be missing something here.</p>

<p>DMOC, I think the answer was 3.14 or something like that</p>

<p>It said no triangles could be formed that are congruent. But there is an infinite amount of non-congruent triangles. But i’m not sure because if it does not exist, it might not be able to have a non congruent or a congruent. lol, whatever. I don’t know, I think that’s a very ambiguous question. And I tested the situations for the I and III problem or whatever, and I got it to work out. But I don’t know. Those multiple answer questions are tricky sometimes.</p>

<p>That wasn’t one of the answer choices.</p>

<p>It was</p>

<p>A: -21.blablabla
B: 1.20
C: 1.23
D: 1.71
E: 1.74</p>

<p>I think I got 1.20 for the x^3 average question.</p>

<p>I think it was something like (7.5 + x)/(5 or some other number) = x^3. Rearranged it and graphed it and got x=1.2ish.</p>

<p>For the cos67, sin67 one I think I put 1/cos67 but I can’t remember too well…</p>

<p>It was pretty easy, you add (x+ all the values)/5=x^3, and solve for x using a graph, i got like 1.20. and the cos(67) one was the last one, it was E. sec(67).</p>
