<p>the question about 2 die, one with 1,1,2,2,2,2 and something else, the probability of getting 1 and 2 or 2 and 1..</p>
<p>the heart beats per minute (i put down 60) </p>
<p>i said the function graph was the one above the x axis, turning up (A)</p>
<p>what do you guys think the curve will be?</p>
<p>it's not 1/2x-2.. it was something else with 1 as the coeffient of x.</p>
<p>i almost got tricked by that period problem. its A, not E.</p>
<p>stupidestofthesmart I agree with you. I took it as well in June and I think this time was easier. Anyway I am not sure if it is not because I was better prepared. And as not hard as it was I still omitted 4 and mistook one- for sure! And if i have done some other mistakes (whcih undoubtedly I have with all my carelessness) I`m ruined! :(</p>
<p>Reading all those makes me feel like freaking out. I just prefer to wait the score without thinking of the test any more.</p>
<p>The period problem was 120 right?</p>
<p>Road runner... why?
1) 1/2 x-2, why not that
2)That period problem.. what was the trick? There was only one that did not have 2 in front of the X, I think that was A</p>
<p>i got 60 for it</p>
<p>no, it was 60. and this test is too easy to be true.</p>
<p>Yeah aberine im just going to wait. Many careless errors, all I can do at this point is hope.</p>
<p>The period was was definitely A because it had a different x coefficient than the others.</p>
<p>How do you solve the heartbeats problem?</p>
<p>I see where you're going with this. Did you say P=1-.6<em>.4=.76? Because I think it was supposed to be: P=(1-.6)</em>(1-.4)=.24</p>
<p>no. it explicitly said it was independent, in which case you must add them both and subtract .6x.4</p>
<p>Fellows,</p>
<p>The finding f(x) problem, the answer was (x/2) -1</p>
<p>I hope I'm allowed to discuss this, if not, please don't punish me:
Here's why:</p>
<p>g(x) = 4x</p>
<p>f(g(x)) = 2x-1</p>
<p>Thus,</p>
<p>(4x)/2 -1 yields 2x-1.</p>
<p>Vwalla.</p>
<p>really the period was 120 :) <em>HAPPY!</em></p>
<p>on the function problem you just needed to plug in and you would find that only one worked.</p>
<p>there was one lim problem though that bugged me ....... what equals limes of infinity?????? 0 or infinity?</p>
<p>what did you guys get on the problem about pumpkins? did you say d/dx(x^2-4) is 2x or 4?</p>
<p>my test didn`t have a problem about pumpkins unless it was #50 #47 or #48 i omitted those in the rush!</p>
<p>What pumpkin problem? And I didn't use derivatives for any problem either.</p>
<p>And for the infinity/infinity limit, I just used L'Hopital's rule. I don't know how to solve that limit with algebra.</p>
<p>do u remember the question asking what does that expression (literal translation from bulgarian-not sure of the term) approach as x approaches infinity?</p>
<p>the limit one is 2.</p>
<p>what did you guys get on the absolute value, and it asked how many solutions one? i got none. cuz i plug that in calculator, there is no intersection.</p>
<p>No solutions because you have 2 absolute value expressions, and the one on the right is made negative, so there's no way they could ever be equal (left is always positive, right is always negative)</p>
