<p>.64 for number 49? Number 46 was choice E.</p>
<p>4 O and 1 W, WHAT IS THAT GUYS>??? please.</p>
<p>probably an 800</p>
<p>For the one with 5^xy<1, xy<0 was the answer unless I am mistaken.</p>
<p>that’s what i got too</p>
<p>hey man, do you know what no. 45 problem was???
by the knight’s list</p>
<p>Can anyone explain the f(x+1)= x * f(x) ?</p>
<p>The dice one annoyed me so much that I after i solved it because I left it blank</p>
<p>2 die, 112222
122222,</p>
<p>and it asks probabiltiy of having a 1 AND a 2, so the chance of having different numbers.
So i solved for chance of having same numbers,</p>
<p>which is 2/6 * 1/6 for the ones
and 4/6*5/6 for twos</p>
<p>2/36 + 20/36, wich is 22/36, so chance of having different numbers is 14/36, which is 7/18.</p>
<p>was that an answer choice?</p>
<p>and they also gave me k^2 + 4k = 3t</p>
<p>i put zero… what are the 2 answers if right side was zzero?</p>
<p>thanks for the solution whatisthis. ^^</p>
<p>and 14/36 was an answer choice.</p>
<p>Would anyone please tell me what the different distance was?</p>
<p>PLEASE solution please.
Q:
Someone goes 35 m/h, and other 40m/h
distance is 20.</p>
<p>how do you solve this?
This is how I did.
(20/40) X 60 = 30 minutes
(20/35) X 60 = 34.2857 minutes</p>
<p>I thought the difference was 4.28
Is this right? no?
ARE THE NUMBERS RIGHT? DUDE I AM PANIKING</p>
<p>Your 14/36 answer is correct. f(x+1)=x*f(x) was tricky.</p>
<p>They gave you f(1) = 1. That means f(2) = f(1+1)=1<em>f(1)=1.
f(3) = f(2+1) = 2</em>f(2) = 2<em>1 = 2
f(4) = f(3+1) = 3</em>f(3) = 3<em>2 = 6
f(5) = f(4+1) = 4</em>f(4) = 4*6 = 24 <–answer</p>
<p>For that last problem, there’s an answer explanation floating around this thread somewhere. . . . Looking at the earlier pages.</p>
<p>Koharvard, I think you read the problem wrong. One of the speeds was 30 mph, I think, not 40.</p>
<p>hey, what do you think is 7 omit, maybe 1 or 2 wrong</p>
<p>Kean is right, it was 30 and 35.</p>
<p>And I did solve that f(x+1) question later as well. I was in a rush and made a mistake</p>
<p>4w and 5 omit? is that like a 780?
I retook it after a 770. ■■■.</p>
<p>whatisthis, the two solutions for k^2+4k=3(0) are k=0 and k=-4. The answer was -4/3.</p>
<p>Thank you 240000. I’m sad now.</p>
<p>do you guys think it was harder than usual? like 43 is 800?</p>
<p>yeah it was alot harder than the ones in the blue book …</p>
<p>so how much would about 10-12 omitted be? point wise? my goal is 700+? is that possible… unless there is a huge curve??(i think a 680 would work also, but nothing less than a 670)
so 10-12 omitted and say 1-6 wrong?</p>
<p>i am really hoping the curve is HUGEEE…math is my best subject (besides science) and i dont know it didnt feel right… i studied so hard, but i focused more on solids and all… i knew the rest but there were some tricky ones… I hate (HATE) probability… just so damn annoyingg lol</p>
<p>also i just read somewhere that
if the test was hard then the curve is 7 points
and easy is 4/5?
idk if thats true, but based on what i have read here, i think it was fairly hard?? i hope so… omitted 10-12 so im nervous…</p>
<p>yeah i felt it was a little bit harder compared to the practice tests.</p>
<p>2nd part of the test was definitely harder</p>
<p>yeah i’m really hoping for 43—800</p>
