<p>can someone explain to me why the 3 circle ones answer is 4/7 instead of 6/7</p>
<p>Please: Does anybody know if the answer was C to the question with the surface area, it had 5x,2x,3x.</p>
<p>@ brian because i spent 3 whole minutes and plugged in all the answer choices and 6/7 is the only that worked</p>
<p>it was 6/7
The question about the wrapped chocolates was ambiguous. The question never explicitly states that there are other types of candy in the package, or if wrapped chocolates can be classified as in the wrapped mix and in the chocolate mix.</p>
<p>If 70 candies were chocolate and 20 were wrapped and there are 0 wrapped chocolates as the answer supposedly is…</p>
<p>then the bag simply consists of
70 chocolates and 20 nonwrapped candies…where are the other 10 candies?</p>
<p>Essentially</p>
<p>70% of 100 candies are chocolate.
20% are wrapped candies (could include chocolate)</p>
<p>20 candies are wrapped
70 candies are chocolate (whether wrapped or unwrapped is unknown)
if the answer for wrapped chocolate is 0
then there exists no inclusion within the venn diagrams…and both are independent.
so all you have are 20 wrapped candies (nonchocolate) and 70 unwrapped chocolates which don’t add to 100</p>
<p>I got the damn 666 thing wrong i included 1000 fuhhh…and for the chocolates…I just thought the question was ambiguous and up for interpretation…and shiould be removed.</p>
<p>^ i put 667 too, i have faith in it though </p>
<p>and i also put 10 for the wrapped chocolates</p>
<p>holy **** i got 667 too…wth?thot 1000 is included</p>
<p>if 1 grid wrong is 800 possible?</p>
<p>@fightin</p>
<p>how can u have faith in 667? hoping it really didnt say LESS THAN? lol</p>
<p>precisely LOL</p>
<p>Did anybody email collegeboard about the distance to line l question? I think I got the answer right (4), but if collegeboard voids it, what happens to the curve? What if they take that question away but you already got it right? Do you get any benefit, or only those who got it wrong?</p>
<p>FIRST OFF, IT’S BEEN ESTABLISHED: 0 WRAPPED CHOCOLATES BECAUSE THERE IS A POSSIBILITY OF NO OVERLAP BETWEEN 20% AND 70%. ALSO IT IS 666 BECAUSE 1000 IS NOT INCLUDED IN THE COUNTING PROCESS. (It clearly states: How many numbers are NOT a multiple of 3 that are LESS THAN 1000?)</p>
<p>SECOND, THE ANSWER TO THE PROBLEM WITH 3 CIRCLES EQUALING PI IS 4/7. WATCH:
BY PLUGGING IN YOU WILL GET:
[(4/7)^2 * PI] + [(4/14)^2 * PI] + [(4/21)^2 * PI] = (441/441) * PI = 1 * PI = PI!
<strong><em>^</em></strong><strong><em>^</em></strong><strong><em>^</em></strong>__
<em>1ST CIRCLE</em>__<strong><em>2ND CIRCLE</em></strong><strong>3RD CIRCLE_
1 * RADIUS</strong><strong><em>1/2 * RADIUS</em></strong><em>1/3 * RADIUS</em></p>
<p>
</p>
<p>That’s not true. The answer is 6/7. Here’s why 4/7 doesn’t work.</p>
<p>(4/7)^2 = .3265
(4/14)^2 = .0816
(4/21)^2 = .0363</p>
<p>.3265 + .0816 + .0363 = .4804</p>
<p>6/7, on the other hand, works.</p>
<p>(6/7)^2 = .7347
(6/14)^2 = .1837
(6/21)^2 = .0816</p>
<p>.7347 + .1837 + .0816 = 1</p>
<p>1*pi = pi.</p>
<p>the one with the surface area i put 62x^2</p>
<p>Are we sure that the triangular prism volume (200sqt3=answer) problem is non-experiemntal?</p>
<p>Ok - I put 6/7, good to know I am not stupid…</p>
<p>However I did miss 2… I didn’t know how to so the 1000/3 problem and for some reason I said that the length of a equilateral triangle is also its height…</p>
<p>oh well, what is the best score you can get missing 2?</p>
<p>what was the question with the remainder 2?</p>
<p>briangt: you could possibly get 770, but most likely 760.</p>
<p>Did everyone get the triangular prism volume (200sqt3=answer) problem? Anybody here not remember it?</p>
<p>what was The problem with the remainder 2?</p>
<p>Yes the answer was 200rt3. And i think i got that one that’s 6/7. I just didnt care to test out the numbers here. But on the test i did. And if 6/7 was C i got it. What i was thinking of was the distance the guy walked downhill and that was 4/7. But umm, ya you guys get it.</p>
