<p>did you have the area surface of the blocks question as well? if so, is it on the 9th section?</p>
<p>caddyshack233: That was definitely experimental. I said this on a previous post. The difficulty level on that section spiked through the roof comparatively. I compared notes with a friend after test and he didnt have it.</p>
<p>I did that section and checked my work to make sure i had them all right just in case though. You really never know on a test and it can come back to haunt you.</p>
<p>i dont remember seeing anything about concentric circles... explain it in more detail please, and if i didnt have it then that one is probably your experimental.</p>
<p>ok...someone please answer me on this... I think my math experimental was the section in which the last question somehow involved leap years... do you guys agree? anyone else have this?</p>
<p>I had nothing with leap years.</p>
<p>Dont remember any question regarding leap years</p>
<p>Taffy it was like 10 concentric circles one inside another. The smallest in terms of area is 1/2 the next smallest and so on. Question was which circle had twice the radius as the smallest. Pretty easy since it logically cant not be the next one. It might fool some ppl but heck it was toward the end of the test so it has to be a little tricky. Basically it is the third smallest because radius is squared. Im 100% sure that section was experimental.</p>
<p>lixuelai, are you talking about the section 6 where the 3 small sqaures are in the circle of area (2Pi)? (the same section had a question about numbers being "powered up" or something when n + r =7t or something to that extent? I asked my friend who had a CR experimental and he also had this section</p>
<p>yup, i definitely didnt have that section. leap years and concentric circles, no thanks.</p>
<p>okay, so there were TWO experimental sections???? I had 4 math sections but had nothing with the "conocentric" circle thingy or whatever...."ahh...the best thing we can do is wait until it comes out on the cb website later this week. Unless we'd like to keep speculating about which one is the experimental. I think it was section 6....but thats just my hunch. anyone else think so?" CB tells which one was exp... or are you saying we could tell by our score :-D</p>
<p>i think the problem is that everyone remembers different problems in different sections. I thought my experimental was section 6 but then i noticed everyone talking about the 15 Mean + 20 = New mean 19; therefore, i guesss that wasn't the experimental. I didn't have anythign about cocentric circles or leap years.</p>
<p>which sections were these problems in?:</p>
<p>2 parabolas f(x) and g(x) and g(x)s vertex was at (0,-1)??</p>
<p>and</p>
<p>a#b was like biggest factor of a times biggest of b.</p>
<p>and </p>
<p>the dice probability question</p>
<p>i didn't have that section. i had a section (6) where: 1) they had lines, one of which intersects the vertex of a parabols and they want you to find another point on the line. 2) They say that a term is "powered up" (or somehting along those lines) if n + r = 7t , 3) They mean was 15, after adding 20, the new mean was 19 4) There were 3 small squares evenly disperesed around a circle. Anyone else have these? Are they experimental?</p>

<p>d3!ty, they are all what i got, does anyone else have them? they are in section 6, i think</p>
<p>JimShaw, i mean concentric circles. I dont call squares circles :)</p>
<p>d3!ty, for the percentage of the kids with more than two siblings i dont remember getting that answer.</p>
<p>There was like 5 kids who got 1 siblings, 6 kids who had 2, 5 kids who had 3, 3 kids who had 4 and 1 kid who had like 5. Which is 20 total. I dont see how 65% works because 5+3+1 = 9. 9/20 =45%</p>
<p>I put 45% as well. However, I'm positive that the question read 2 or more siblings and there were 5 kids who had 0, 6 who had 1, 5 who had 2, 3 who had 3 and 1 that had 4. and 5+3+1=9 9/20=45% also</p>
<p>oh yeah lol, srry just off by a bit but still the same :)</p>
<p>couldnt really remember it but i do remember i got 45% so i kind of worked backwards.</p>
<p>Btw there is no way to get 65%. 65% of 20 total is 13 which is impossible to get one way or another.</p>
<p>Hmm I'm pretty sure I got that one right, maybe I'm mixing my numbers up. Because I KNOW I got 9 as the sum.</p>
<p>hehe it happens. Confused another problem with it probably. Scared me for a sec though :) Anyone else want to confirm answer is 45%?</p>
<p>well if you got 9 as the sum then im 100% sure it is 45% since the first 3 is 5,6,5. 5+6+9 = 20</p>
