<p>yeah def. said least.... loved that question... so deceptively simple</p>

<p>Is it bad if I get 770 first time and get 800 on the second test?</p>

<p>I'm still considering canceling my score..</p>

<p>If I need to cancel it.. what should I do?</p>

<p>Plz answer me >-<</p>

<p>Mr. Evil
I am sure that the answer is the one with the CUbe
plus, i would just like to share the criterion for 800
A. 8 omit
B. 6 wrong
C. 4 omit 3 wrong</p>

<p>RED SOX
what did you guys get for the standard deviation problem and the problem where you had to find the distance between the origin and the closest point to the origin on the circle???</p>

<p>so for the first question
the answer is that RANGE and STand DEVIATION are same</p>

<p>and for the second question, you had to subtract the radius of the circle from the distance between the center and the origin, so the answer was 9 positive</p>

<p>THE ANSWER IS B for number 50</p>

<p>the answer to that question f(100) is 1</p>

<p>is the farris wheeel with like complicated cosine equation and asking something involving the number 30 ?</p>

<p>if thats true the answer is 7. something, which is choice A</p>

<p>cocentric circle
the answer is 5571</p>

<p>((4/3)pi(11)^3)-((4/3)pi(1)^3))</p>

<p>Distance between origin and point on circle:
Take coordinates of circle's center ((x+h)^2+(y+k)^2, where h,k are coordinates of circle's center) and plug into distance formula to find distance b/t origin and center of circle. The circle equation was =to 16, meaning radius was 4. So subtract 4 from the distance found earlier to get the answer.</p>

<p>jishuca, it's not bad to get a perfect the second time...if u still want to cancel, go to the website and there should be a way or call up collegeboard</p>

<p>no sense in cancelling unless you'd get less than 700.</p>

<p>anybody else get f(100) = 2?</p>

<p>Once more.... proof that f(100) equals 1. The pattern repeated itself over a 7 space period. I started with 4. Then i added 91, which is divisable by 7. Which means at 95, the pattern was at the same spot as four. Then i went along 5 spaces and the y was at 1. Considering everyones saying it... and ive done it over like 3 times in my head... its 1. Case closed.</p>

<p>i got f(100) = 3 :P</p>

<p>Yeah, I got f(100)=3 too.:) Haha I can't believe how people overcomplicated this problem and did some divisibility shiz and said that the answer was 1 or 2. Sad really...the function crossed the y-axis at 3 and it repeats every 20 like any curve so f(100) would be 3.</p>

<p>Yeah... that would be true if it repeated every 20.... sadly it repeated every 7. It went 0, 1, 1, 3, 1, 0. I really dont see why your arguing if you dont remember the problem. At x=0 the y value was 3. Recognizing that fact we know that at x=98 y equals 3. Now we just move to the right two spots. Voila 1.</p>

<p>what did u guys get for the question involving the use of sin law?
like given angle A and C, find the length of AC or something</p>

<p>^ sorry timeless, don't remember that problem</p>

<p>but about the period problem, i'm pretty sure the answer was 1.. but i guess we'll see when scores come out. anyone gonna order the score report?</p>

<p>what is the score report?</p>

<p>The score report is free. You can access it online and CB will also mail you the same copy. The score report shows your raw score, the numbers of right, wrong, and omitted questions, and other basic information.</p>
