<p>What ellipse? I didn’t have an ellipse</p>
<p>i think for ellipse i got a=2 and b=4/(root 3). matrix one i got 0 but did not know how to do it. i omitted the weird standard deviation one.
not sure if i got the f(-7) right but i got -1
ommitted a couple others that i didn’t have time to do. crap this test got exponentially harder by the end</p>
<p>Me too! Didn’t even recognize half of those words. And knowing my teacher was so behind I taught myself like atomic, nuclear, quantum and theory of relativity and nothing I studied was on there. It was an awful test</p>
<p>Oh yeah I got b=4/rt3
I didn’t know what standard deviation was. And I had to teach myself probability.</p>
<p>Agree with almost all of these except the circle one “tan 120” being -sqrt3. I put that but isn’t it in a circle not an xy axis so would it just be positive bc there is not like a negative distance from an origin?</p>
<p>Guys, what did you think of the test? Me, I thought it was a lot easier than the one from January but the last five questions still seemed almost impossible. I had to omit six questions and I probably got a few that I answered wrong. What do you guys think the cutoff point for 800 would be? Higher or lower than the one from sparknotes?</p>
<p>Also, for the question that asked what the matrix [[a,b][c,d]] was if the set of equations had multiple solutions, what was the answer? I chose 0…</p>
<p>Oh and what was the answer to the standard deviation question? Was that 0 as well?</p>
<p>48m^3, for the volume of rectangl</p>
<p>I never saw normal distribution and onto functions questions in barrons where did they even come from</p>
<p>^Faizanel I thought for the onto function one just pick the one with the range R right? Which means a y=x-1 or something?</p>
<p>Who else thought that this test was super hard? I did both of collegeboard’s Math 2 tests prior to this test for practice, and both were MUCH MUCH easier. </p>
<p>@promotional, yes that is what I got as well.</p>
<p>What did you guys get for the matrix/determinant question?
The question went like…ax + by = 2 and cx + dy = 3 has infinitely many solutions. What is the determinant of ( a b c d) ?</p>
<p>I put -1 …</p>
<p>Hopefully the curve will be nice. Reading through this thread it looks like I got 2 questions wrong for sure. </p>
<p>For the exponential question where it asked you to find the two months where the population (of bacteria?) was maximum, did everyone else get February and August?</p>
<p>Do you guys remember 1/27 for anything?</p>
<p>Std deviation from the mean was 0. Easiest question on test if you’ve had stats. Also, matrix/determinant one was 0</p>
<p>They weren’t any more difficult than Barron’s review books in my opinion</p>
<p>omitted 4, missed at least 2. ugh</p>
<p>Hey What did you guys get </p>
<p>the volume for the prism? Is that like 18m^3??</p>
<p>Also, the sin theta = a sin(2theta) = ?</p>
<p>@jansatomg i got whatever the highest number was (E)… do you remember the lengths?</p>
<p>^omgitsvicki I remember h=9m… but not the others…</p>
<p>^ are you sure its h=9m… i remember one being m and one being 3h i think…</p>
<p>Omitted 3 and 1 wrong so far. Praying. And for the rectangle I got 36rt^3 and for the ellipse I am positive that a is 2 and b was sqrtrt3/4</p>
