<p>yes, 321 million and yes, it was -12. I had to switch around the sign for the x-y or y-x or whatever it was into the other thing, making 6 negative and making x+y a negative number as well.</p>
<p>what’s the answer to the senior/junior probability question? </p>
<p>And what’s the curve usually?</p>
<p>they gave (x^2-y^2)=72 which is (x-y)*(x+y)=72 since -(x-y)=(y-x)=6 you get 6(x+y)=-72(since you multiply both sides by -1) then divide -72 by 6 and the answer is (x+y)=-12</p>
<p>@ocean ambition
it was like a complex plane q and geometric sequence i beleive
i don’t remembt the specifics aside from the fact that you multiply the previous term by “i” to get to the next
oh and it was asking for the 99th term believe and ure given the 10th term i think
and i ende dup with -2-2i</p>
<p>The boxplot question was basically asking for the definition of a boxplot. The answer was 50% and I’m totally sure.</p>
<p>Ricky, it’s gone. :[ Sorry.</p>
<p>oh its ok thanks anyways 
but u think u got -2-2i right?</p>
<p>it said y-x=6?!
noooooooo =((((</p>
<p>it was like a0=i(n-1)
a9 was -2-i? or something along that sort and you had to find the 100th term or 99th</p>
<p>This may be a dumb question, but when do they post scores online?</p>
<p>june 25th i belivee</p>
<p>for 49, the box and wisker plot, anybody remember if the answer was c? i dont remember what numberical value was, anybody know?</p>
<p>for the exponential population growth question, how the hell was the rate 1.0092? it said it was growing by .92… god so stupid, that doesnt even test math skills, its just confusing</p>
<p>Same day as the other SATs, June 26</p>
<p>it was 1.0092 cause 1 includes the original number. 0.92 was the percent.</p>
<p>Guys I didn’t do any math for the boxplot question (49) but I can tell you that in a boxplot the “box” represents the interquartile range, which is from the 25th percentile to the 75th percentile, making the correct answer 50%.</p>
<p>Rickymatsui for the last question I got 2 - i… it gave you that the 9th term was -2 + i and that each term after was i times the previous term… this makes the 97th term the same as the 9th term (multiplying by i 4 times brings you back to the original number) and then multiplying by i 2 more times (the same as multiplying by -1) makes the answer 2 - i.</p>
<p>wasnt it the 10th term? not the 9th? :(</p>
<p>
No, you need to know the formula.
(initial)*(1+growth rate)^term</p>

<p>There was a question that I think I left blank (which was stupid) that said a painter was painting the walls and ceiling of a room and provided the 3 dimensions and asked how much area he would be painting. I found the surface area of the room, which was an answer, but since he wasn’t painting the floor I subtracted the area of the floor from the surface are and what I got wasn’t an answer :/.</p>
