<p>um depends maybe march</p>
<p>then u might get 210? i dunno. i dont think it matters that much</p>
<p>come on you didnt miss every question/////</p>
<p>you can't expect to get a very good score on math if you missed 3+. math always gets the worst curve cuz everyone gets 800</p>
<p>I got 32 for the beads question. What did everyone else get? Also, what was the question about professors? I do not remember that question.</p>
<p>20 for that</p>
<p>20 for beads</p>
<p>wat was the beads question btw? i dont remember.</p>
<p>The beads question was something like this:
You have a jar with wooden, red glass, and green glass beads. There are 4x as many total glass beads as there are wooden ones. The probability that you pick a red glass bead is 3x more likely than picking a green glass bead. How many beads are in the jar?</p>
<p>So if you have 12 red beads, you have 4 green beads. That gives you 16 total glass beads, and 4 wooden beads (1/4 of 16), so 20 beads total.</p>
<p>--
Also, for the problem that was like "if x is an odd integer, what is the smallest odd integer greater than x", everyone got "x+2", right? The question just seemed so easy that I'm doubting myself.</p>
<p>its 20 beads</p>
<p>thanks mike10123. i got the beads question right then. and for the odd integer one, i got x+2 too.</p>
<p>Ehh, people are probably sick of me for this question by now, but can someone workout the x^2=4y^2 and x=2y+1. I can't see how it is 1/2 because:</p>
<p>(1/2)^2=4y^2
1/4 = 4y^2
1/16=y^2, ergo y=1/4</p>
<p>Then if you plug it back in,
X=2y+1
1/2 = 2(1/4)+1
1/2 = 3/2, which doesn't work.</p>
<p>y is negative 1/4.</p>
<p>(2y+1)^2=4y^2=(2y)^2
(2y+1) can't =(2y)
so (2y+1)= -(2y)
asking for x</p>
<p>Now that cat's out of the hat on this test:
4k/3 was from
2^n + 2^(n+1) = k
2^(n+2) in terms of k?</p>
<p>to 8.....8

can someone explain the 52.......... boundary squares.....</p>
<p>It was like a box has n rows with n boxes in each row and k boxes around the border...what is k
[/quote]
</p>
<p>on the square board n x n
in the boundery: take away 4 corner squares, there 4(n-2) left, so altogther k=4(n-2)+4, gotta be a multiple of 4. only 52 fits.</p>
<p>blah123 sez in#90
[quote]
n^2 - (not in boundary)^2 = k</p>
<p>14^2 - 12^2 = 52
[/quote]
k=n^2 - (n-2)^2= 4n - 4 ----------> same thing.</p>
