<p>yeah. i belived the average proportion wsa .25 or something close to that number.</p>
<p>man, i did everything right, but for some reason i remember putting B for that question..i hope i didnt get it wrong.</p>
<p>Anyone know how to do the problem with f(-1)=1 where there is symmetry or a reflection across the line x=3 then it asked for f(-7).</p>
<p>isn't that still 1?</p>
<p>the answer is negative one</p>
<p>its symmetric to x=3
both x=-1 and x=7 (it asked for f(7) not f(-7)) are 4 units away from this symmetrical line</p>
<p>thus their results should be identical...right?</p>
<p>i put 7....</p>
<p>I agree with azn4eyes00 because x equals 3 is horizontal so symmetric should be vertical, shouldn't it? So y would always be negative one.</p>
<p>azn4, I'm not sure whether it was -1 or 1 but mine was identical from the question as well.</p>
<p>gahh. i dont know why i put myself through the stress of going over all the answers. all of a sudden i dont feel i did so well lol
:/</p>
<p>i got something 12 for the probability question as well.
because couldn't you have reversed 2 and 3 and make it 3 and 2 as well?</p>
<p>and i thought it was easier than what i imagined.. but i didn't get to finish all questions since i spent some long time on the questions that i didn't want to make stupid mistakes on lol.</p>
<p>same here some-dude</p>
<p>me neither I just can't wait until I see the scores. especially this one. I heard some engineering schools won't even look at students without 800 on mathII. And I am so freaking out.</p>
<p>fivewinks, i believe the question said that the 3 always precedes the 2 (or 2 precedes the 3), but not both.</p>
<p>therefore i think the answer was just 6...
..i hope.</p>
<p>fivewinks: It said that 2 was immediately followed by 3, so you treat "23" as one digit.
Wait, can we return to the last question? Did you guys get .932?!
Also, the one with the p^2<em>q^5</em>r^something, wasn't it B? Because that was the least one where you could just cancel out the denominator/divisor and you would just get the pqr multiplied together which is an integer? I'm confused.</p>
<p>um X=3 is verticle?</p>
<p>what about the triangle with the sides 5,6, and 7? i think i got something like 112... or something...</p>
<p>do you remmeber that question??</p>
<p>heyli: yeah, x=3 was vertical.</p>
<p>goodatlife, use law of cosines and you should have gotten 78 degrees</p>
<p>right, therefore, the line symmetric to X=3 should be Y=some number, in this case = -1 and its horizontal. so shouldnt the anwser of f(7) still be -1? because X=-1 and X=7 are on the same line.</p>
<p>Does any remember other questions?</p>
<p>I remember the first one which was really easy....it was .037...rigght?</p>
