<p>lololol. kids the next Terence Tao apparently.</p>

322

<p>Lololololol. Dat reaction doe.</p>

323

<p>this is humanities: <a href=“http://fakeplus.com/pictures/jpg/math-genius-is-offended_20120402143437.jpg[/url]”>http://fakeplus.com/pictures/jpg/math-genius-is-offended_20120402143437.jpg&lt;/a&gt;
lmao</p>

324

<p>On an unrelated note, that girl tho. Whooeee.</p>

325

<p>Wait was 58 d?</p>

326

<p>@sillyup (concerning the curve) I don’t think the curve will be that difficult. Maybe for 33-36, but I doubt the difficulty after that. I’ve gotten 23s on practice tests I’ve missed 24 questions on. </p>

<p>Gah the math test is worrying me. I circle the questions I’m not for sure of along the way, and I had like 7 circled. Hopefully the curve is nice. Just with guessing on those 7 should give me 1 or 2 correct answers by probability. -5 hmmmmm</p>

328

<p>Lol if 58 was d then i got a 36 i believe</p>

329

<p>Anyway, I never received a definitive answer on whether (v/lw)-d, which is the correct answer for #59 the dirt digging problem, was answer choice E… Because I got that answer and marked down E. Because I remember specifically that answer choice B had (v+d)/lw and answer choice C had (v-d)/lw, both of which are wrong answers. And I remember there being an answer choice (D) in between the correct one and those two. Can anybody else confirm this?</p>

330

<p>^Answer choice D was (v/lw)-d</p>

331

<p>was the answer to one of the probability questions 1/3 N</p>

332

<p>yea elizabeth</p>

333

<p>^ That’s what I put, but I don’t remember exactly what the question said. If it was asking JUST for probability, it would’ve been the answer with only 1/3. However, I thought I remember it asking for a QUANTITY assuming there were “N” students… which mean’s you’d have to include the N variable. Not sure though… depends on what the question wanted.</p>

334

<p>trust mehh, it was 1/3n</p>

335

<p>It was asking for a quantity.</p>

336

<p>

</p>

<p>I also got 1/3n</p>

337

<p>i might have made a silly error but for the rational one i got 48 +18 sqrt3 because after you simplified the rational to 3 rad3 wasnt there a 6 you had to multiply by?</p>

338

<p>What was the question to the probably question with an answer of 1/3n? I just don’t remember it and want to make sure that I got it right.</p>

339

<p>I got 48 + 9 sqrt3. Because sqrt 27 simplifies to 3 sqrt3 then you multiply that by 1/2 of the base (1/2 of 6). That equals 48 + 9 sqrt3</p>

340

<p>@Patton370 you are 100% right I got that too. 3srt3 times half of the base (6) = 9srt3 +48.</p>
