<p>I got that too, juventus. What was the 3D xyz box one?</p>
<p>Can someone explain the probability one? I'm sure I misread it bc I was panicking</p>
<p>I think I did okay on math...we'll see. Bio, though, my favorite subject - >_>. </p>
<p>If I come out with relatively bad scores (from what I wanted), but take them again in June, will colleges (Yale, Stanford, UCLA, UCB) look at the lower scores...will it affect admissions, I mean?</p>
<p>I know some of these schools superscore them, but does that go for subject tests as well?</p>
<p>I had -.577. It ended up being tan 2pi/3</p>
<p>there was no +.577. there was only -.577.</p>
<p>the red/blue probability?
they gave you the probabilities for red. You just find the probability of blue, and multiply them. ex. red: 2/3, so blue: 1/3. red: 3/8, so blue 5/8 + multiply. I believe..</p>
<p>the answer to that one ^^ is 5/24.</p>
<p>Hes talking about the probablity of the xy coordiantes being a spot 1 or less from the origin. It was near the end of the test.</p>
<p>No the -1<x<1 probability</p>
<p>The UC's don't care so much. For Stanford and Yale, don't score below a 700 on math 2C... it just looks bad. Even if you take it for a second time and get higher.</p>
<p>The -1 and 1 probability one is like this:
I figured that all the points on the circumference would have a value of 2<em>pi</em>r, or, when you plug in 1 for r, 2pi. Then all the points INSIDE the circle will have the value of the area, which is pi*r^2, or, when you plug in 1, pi. so... pi (or random points picked INSIDE the circle) / 2pi (random points on the edge of the circle) is 1/2... that's poorly explained, but does the logic seem good to anyon?</p>
<p>the answer was 5/24</p>
<p>I got 5/24 for the probability one. It was choice (a). I remember being skeptical because it was too easy. Oh, well. It was right.</p>
<p>But couldnt points be selected that were outside the circle, but inside the 2 x 2 square also?</p>
<p><em>thinks about it</em> wow. that was REALLY dumb of me. <em>gets scared for rest of test</em></p>
<p>well, it's the same concept. perimeter/area.</p>
<p>how did yall get -.577?</p>
<h1>49 with xy=20 and x+y=20 was 1/2 right?</h1>
<p>and the sum of first 225 terms = 113?</p>
<p>So the answer should have been... 8/4... was 2 a choice?</p>
<p>i got the sum of 225 to be 226...
and i got 1/2 for #49</p>
<p>I got 113. That one was from the formula.</p>
