<p>does anyone recall the exact method of finding the # of students in the lab?</p>

<p>the answer was 48, though i forgot how i found it.</p>

462

<p>@daem0n: you could be right too, both of our answers were there…cuz each answer differed only by 8 >:(</p>

<p>@dj04x7: yeah same test, do you think the first or second writing was exp ? or is there no way to tell…lol</p>

463

<p>DOES ANYBODY REMEMBER THE QUESTION <a href=“http://www.skwirk.com/content/upload/images/Primary/NSW/year_4/maths/3d_space/tp1/ch2/tp1ch2_image8.jpg[/url]”>http://www.skwirk.com/content/upload/images/Primary/NSW/year_4/maths/3d_space/tp1/ch2/tp1ch2_image8.jpg&lt;/a&gt;&lt;/p&gt;

<p>and the side length of the square was 6,
did it ask for the perimeter when it FOLDED up
or when it was just plain in sight?</p>

464

<p>Yep i was wrong ■■■.</p>

465

<p>

</p>

<p>In plain sight.</p>

<p>EDIT: I hope.</p>

466

<p>can someone please answer me? there were 2 20 Q sections. which one do u guys think was experimental</p>

467

<p>Does anyone renmember what number question aws the 72 boxes one?</p>

<p>Please helpp!!!</p>

468

<p>Okay Daem0n then did you have the math section with the x/100 at the end and the parabola? Or no?</p>

469

<p>aw man, perimeter of the whole thing woulda been to complicated, i suppose, and i attempted to do that , and now i think it was in plain sight …</p>

470

<p>ill try to prove that im rite using simple #s.</p>

<p>okay so assume period one had 4, per 2 had 5, lunch had 2 and 3 had 3.
since every1 at lunch were at 2 other periods, we can simplify by taking out 2 each from periods one and two to symbolize the fact that the 2 ppl in lunch both went to periods 1+2 as well. thus the new result will b 2 in per 1, 3 in per 2, 2 in lunch, and 3 in 3. thats 2+3+2+3 which is 10. thats TOTAL which is 4+5+2+3 (14)-2L which is (4)</p>

<p>edit: LOL this took to long to write… well incase any of u want to see the proof</p>

471

<p>Umm, perimeter of the whole thing would have just been perimeter in plain sight+perimeter of square base.</p>

<p>But I’m 99% sure it’s plain sight. Can I get a confirmation on this?</p>

472

<p>@blue: yup! what was the answer for that? i did 20+(x/100)^10</p>

473

<p>anyone get 44% for one of them about history in math section? and 4 root 2 for AD(?) that was not shown in the diagram</p>

474

<p>can someone please answer me? there were 2 20 Q sections. which one do u guys think was experimental</p>

475

<p>Can anybody confirm the plain sight/folded up perimeter?</p>

<p>

</p>

<p>Which sections were those (i.e. what were the numbers)?</p>

476

<p>@ daemon and pooh, both of ur questions were on my list of answers btu here it is again
so far:</p>

<p>3x + 4y = 40 answer-> 5.7?
(9,10) was the y= a(x-5)^2 + b
x+y-z is -50
reflected over y = 4 is 5
potatoes 1/4
4 digit =18
9:10
50-50, answer</p>

477

<p>poooh i got 44. @ 314 sections 2 4 and 8 i believe</p>

478

<p>@evilpanda: thanks!! hmm just one question for anyone with my test… Median with x was x=2 or x=5? I put x=5</p>

479

<p>

</p>

<p>2 and 4 are either 20 (all MC) or 18 (MC+grid-in) question sections. 8 is a 16 question MC section.</p>

<p>Honestly, there’s no way to tell which of 2 and 4 was experimental.</p>

480

<p>almost positive 2. :confused: sry lol</p>
