October 2010 Math SAT Thread

<p>And btw was 1/108 choice ‘A’? Or choice ‘B’?</p>

<p>^a…</p>

<p>

I don’t believe that’s accepted :frowning: (pretty sure)</p>

<p>^yes it is accepted. It’s on the CB website. You can look for it :)</p>

<p>@jlewis i don’t think that’s acceptable</p>

<p>Btw, are you talking about the fraction 15/9?</p>

<p>@jlewis, you are allowed to not simplify a fraction in your answer as long as it is the correct fraction.</p>

<p>@dhs, -1 will probably be a 780 or 790.</p>

<p>Was the second grid-in experimental?</p>

<p>phew, thanks guys. just double checked it on the CB website. it said it doesn’t have to be simplified as long as it fits in the blanks.</p>

<p>@user2134 - yeah, I forgot to simplify it down to 5/3</p>

<p>math really needs a final list with total number of answers possible anybody with the time to do this?</p>

<p>i feel like ppl r posting things that werent on my SAT</p>

<p>Did anyone get grid-in math experimental? Was it the second one (section four)?</p>

<p>^Yeah it was the second one.</p>

<p>^Thanks! 10</p>

<p>so the experimental was the section that asked for the number of miles required for a girl to catch up to a friend that was running 3mph and 7 ahead, right?</p>

<p>^yes 10char</p>

<p>that dice question’s answer is 1/54
1/216 (6 6 6 ) this is the probability of getting sum of 18; since,all numbers are same, order is not counted as a different)</p>

<p>3/216 ( 6 6 5 , 6 5 6 , 5 6 6 ) this is probability of getting sum of 17; order do matters!</p>

<p>1/216+3/216=4/216=1/54</p>

<p>6 6 5 has 3 different variants(two 6 are same);
665 656 566
if it was 6 4 3 ( all different numbers) ,then it has 3!=3<em>2</em>1=6 different variants.
643 634
463 436
346 364</p>

<p>Hey, does anyone remember the problem : t = x + 2 t = y - 6, and asks relation. In that question, they specify t, x, y to be an integer, which means they could be negative. Taking that into consideration, none of the answers match. In the end i chose the relation x<y x=“”>y, whichever one came by solving as if they were postive. Did anyone have the same problem.</y></p>

<p>Just to bump it up, here’s the list that was on page 55. It’s still missing some… I didn’t change it at all. </p>

<p>Total: 45/54</p>

<p>Fill-Ins: 10/10
15 paperback
1.2 = radius
290 - locker question
24 combinations
6000 computers difference
5/3 = 3x
10<x<14 obtuse triangle
m = 2
1080 average
8 = least value for which one function is greater than other</p>

<p>Multiple Choice: 35/44
equation is 2x+1 when f(x)=2x
x^2 > 3/5 * y^2 (E)
PR = 8
3a = 20
f(v) - f(t)
x + z = 7
|xy| = 1
y = x/ root 3
119 is the green
july had 8000 less
paralell lines was I and II only
4500 dollars
4 for height of cylinder
15 perimeter of triangle
10 = area of the 5 rectangles
1 is width of box
8sqrt2 distance of diaganol
x/root 3 for slope of line of 30-60-90 triangle
x<y (E) for the t,x,y question
18 - bacteria curved scatterplot
8 - 6x + px = 14x
12 - area of 5-5-6 triangle
3a-20
11-4x-y
5 - pentagon of toothpicks
27 people for survey
three - a/b
x was 45 degrees
(-3,3) - ax^2 - 9
2k = (1+x)(2+4x)
wx = greatest product
1.2 eng quart = 1 brit quart
2(5x-8)
other point y=3 if slope is 0
20 is possible value for 0<x<y<6 when x*y</p>

<p>Could someone tell me what PR=8 refers to?</p>

<p>Also, did anyone else get a question that said, if b=1/a, what does 1-a/1-b equal? If so, was the answer -1/b?</p>

<p>Oh, and is there a possible chance of 1 wrong being an 800, considering how tricky the dice question was?</p>

<p>kartuppuluri: I had that one; I put y>x since 8 must be added to x to get y. Since noone is discussing it, it might have been on the experimental.</p>
