Dec 2012 - Math II Discussion

<p>^ Good point :smiley: thanks! I was a little worried since the math 2 test has a huge curve and a lot of people will have an 800, but I’m sure it won’t make much of a difference to them.</p>

<p>I said the cards question was 35 not 34 :/</p>

<p>@upsilon picking 34 results in card choices of 35-50, which would be 16 choices + 9 cards before the 10= 25 choices for NOT being between 10 and 34, ie, 23 choices between 10 and 34. Also you can double-check by actually writing the numbers 10 through 34 down, taking away 10 and 34, resulting in 23 choices between them.</p>

<p>it was 35, i even counted it out on my fingers, lol</p>

<p>I dont remember the question but I was pretty sure about 34</p>

<p>Parabola and square, if d is (2.3,0) what is the area of the square? (Graph)</p>

<p>area was about 50 (49.266)</p>

<p>@killer lol thats what i did too at first</p>

<p>well it wasn’t a square, it was a rectangle. I plotted the graph and then calculated the value of f(2.3) which equals 10.71. then I multiplied 10.71 by 4.6 (2 times 2.3) which equals 49.27</p>

<p>^ 49.27 is correct.</p>

<p>So for the card question:</p>

<p>A man picks two cards from a deck with 50 numerical cards; the first is 10 and the second we must guess. The probably of him picking a card between 10 and the unknown number is 1/2.</p>

<p>He is already holding two cards, consequently, there are 48 cards left. If half of those are between 10 and the unknown, the difference between 10 and the unknown is 24. </p>

<p>10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35</p>

<p>There are 24 numbers between and not including 10 and 35. Unfortunately, I did not put that as my answer.</p>

<p>you are right, answer is 35. So the only chance of me getting an 800 is that the curve contemplates 43 and having the rest right… I dont feel so confident</p>

<p>4 or 5 wrong would still be an 800 right?</p>

<p>3/5? does that answer ring a bell?</p>

<p>Why are you guys even posting answers here? Don’t worry. Just by asking questions here, your chance for an 800 is that more slim. Chillax.</p>

<p>If I answered everything, how many can I miss for an 800?</p>

<p>@crystalma, it varies from test to test, but generally you can miss 6. I think the consensus was that this test was easy, so 5 is a possibility.</p>

<p>Didn’t answer the one about the plane, and it seems like I got the interquartile range one (just saw IQR and answered 50%, dangit) wrong. Realistically hoping for 800.</p>

<p>The one about “Which is a function?” was definitely II and III. If all of the f(x) values are 1/2, then it passes the vertical line test and the equation could be something like y = f(x) = 1/2 + 0x.</p>

<p>Lately, an 800 is a raw score of 43. So 5 wrong, with the penalty for guessing added on, would give you a raw score of 44.</p>

<p>Why was the cos2x + cosx 3.125?</p>

<p>Anyone remember the problem that asked for the volume of the cone in terms of the height?
I can’t remember any answers choices…</p>

<p>There was someone at my test center who got 2 790s on math II, just wanted to get that perfect score :D. But for me the test was easy, I skipped 2, and according to this thread none wrong so far, looking good :)</p>
