<p>why is it 7? im really confused.</p>

<p>18 (milk ) + 23 ( candy ) + 19 (newspaper)</p>

<p>11 bought only milk
16 bought only candy
12 bought only newspaper</p>

<p>wait. i dont think these were the numbers. can someone explain?</p>

422

<p>What was the exact wording of the question overrated?</p>

423

<p>um I think I first did 60-18=42 since 18 waas the # ppl who bought milk and ppl who bought milk bought nothing else, so that’s out of the picture. then they gave us 26 and 23 i think? ( i forgot sorry) but i used the formula (# who bought A) + (# who bought B) - x = 42 and my answer was like -x=-7…which is x=7</p>

<p>26+23 - x = 42
x=7</p>

424

<p>And also I think for one of the elements it said that those people who bought that item did not buy any other item.</p>

425

<p>60-18 = 42</p>

<p>26+23= 49</p>

<p>49-42 = 7</p>

426

<p>72 different book combos…</p>

<p>wht qustion is that?</p>

427

<p>@dguptaa: i think it was like 6 comic books and 12 biography books…how many diff combinations if each combination has 1 comic book/1 biography book</p>

428

<p>Pooh or daem0n did one of you NOT have math experimental? If so can you tell me what your math sections were?</p>

429

<p>UHH overrated. i believe the answer is 7 because there are 67 items bought and 60 people total. and ur #s were correct. 18,23,19 bought. the 18 only bought the milk. x # of ppl bought a both from the 19 and the 23. since x is counted twice basically u subtract x from the total and that has to equal the 60 total. so 18+x+(19-x)+(23-x)=60 x=7</p>

430

<p>for the sphere Q, this is y i think da answer is root 2 </p>

431

<p>4 wrong, 1 grid in 2 omit score???</p>

432

<p>@blue: i think my experiemental was writing not math. anyways i had a math section that began with a line that had a total length of 18… um something about 2 pie charts that shows women/men’s interest in music (jazz, other, etc). something about a sphere in cube with volume 8. one math section had a last problem about 20 million in 1990 and 24 million in 1994…sry don’t really rmeember, maybe if you told me yours</p>

433

<p>futuresuccess, uhhh u do know that a circle doesnt reach the corner of a square right?..its physically impossible, it curves around the corner</p>

434

<p>Hey
Err…i’m not sure which sections I had</p>

<p>I had the griot question as an experimental (I believe)</p>

<p>I also had the sphere inside a cube of area 8
A circle inside an equalitaral triangle inside a larger triangle (75 pi)</p>

<p>What were some questions on a math experimental?</p>

<p>@future, i agree with evil panda, a circle of radius root 2 cannot fit
cube of area 8 = cube with side lengths of 2 (2^3=8)
therefore, diameter=2, r=1</p>

435

<p>futuresucces: Thats not a diameter. If you look there is a space between the cube and the corner.</p>

436

<p>4 wrong (1 grid in) 2 omit, score???</p>

437

<p>^680 probably</p>

438

<p>does anyone remember What number the 72 books one was?</p>

<p>And what letter choice was 72?</p>

439

<p>Okay Dam0n let me help. How many math sections did you have? 3 or 4? If you had 4 you had an experimental math. If you had three you did not get an experimental math. Also, griots was NOT experimental just so you know.</p>

440

<p>@dugptaa: 72 was 12*6 or something for books; i have no clue what number/letter it was
@flcollege: that would be impossible…where would those two legs of 1 come from?</p>

<p>QUESTION:
ax^2+bx+c=1
x^2+bx+c=-5
@x=-1</p>

<p>solving for a, a is 7 right?</p>

<p>@blue: i believe it was 3. I had a passage about mehndi, writing (HEATH), farming, and robots and whole bunch of nonsense. (c/p from another thread), so i think it was experimental cr, not math</p>
