Dec 2012 - Math II Discussion

<p>That’s the one about cards, the answer 35</p>

<p>yea ik but where in the question did it say not including 10 and n</p>

<p>It said there are 24 numbers BETWEEN 10 and n. Which means there should be 24 numbers NOT INCLUDING 10 and n.</p>

<p>11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34…sigh thats a mean trick</p>

<p>in that 1/n^2 + 1, was n= 10 or n= 9?</p>

<p>It was 10.
1/82 = 0.0122
1/101 = 0.0099</p>

<p>if n=9, we’re .0022 away from being exactly .01
if n=10, we’re only .0001 away…</p>

<p>guys the question asked Y AS A FUNCTION OF X… NOT X AS A FUNCTION OF Y… so it couldn’t be II and III.</p>

<p>wasn’t it I, II, and III? because none of them had two of the same x values that go to different y values</p>

<p>(I) has 2 different values of y for x=0</p>

<p>how did i not see that ?? ahhhhhhhhhhhhhhhhhhh i remember specifically looking for that ***</p>

<p>Can anyone explain to me the circle and plane question?</p>

<p>for the 1/ n^2 + 1 question , was 9 choice C or 10 choice C i jst remember putting C</p>

<p>How did you guys manage to get by so fast? I was so stressed and had to leave the last 11 question omitted!? I did not use that much time on every question. So I omitted 13 (!) total, and properly missed 3-6, so I am not getting my hopes up for this one. </p>

<p>But - how do you manage to get all 50 questions?</p>

<p>^Same question. I couldn’t even solve 40!</p>

<p>There’s ways of solving most of the questions on your calculator. You just have to recognize what you need to do very quickly. Practice, basically.</p>

<p>Would you guys say this test was difficult, average, or easy? I hope the curve is nice :(</p>

<p>me too.
i went in thinking it would be a sure 800.
i omitted two but felt good about the rest.
then i realized that i made three careless errors and one i thought was right was wrong.
so im right on the cusp</p>

<p>Ahh, I didn’t go in thinking it would be an 800, I was so nervous, I thought I was going to throw up, I have trouble keeping my cool before tests, It didn’t help that there was a kid there who is really good at math, and got 2 790s on math 2. I’m glad I used barons and timed my tests, they made the real test seem really easy.</p>

<p>I finished with 15 minutes left over… So I just double checked the ones I was unsure of. I’m pretty sure I got an 800 with 2 wrong, 0 omitted. And if you guys have problems with time issues, practice is the only answer. Practice, practice, practice! And don’t spend your time on Barrons Math 2 UNLESS you are bad at math. If you are decent, PR is fine. Also happy nothing hard on series/sequences because I forgot most of them.</p>

<p>what number was the circle and the plane question?</p>
