<p>what do u think the curve is gonna be. e.g. how many to get wrong to get an 800</p>
<p>wait I thought that was a cylinder with the cut in half. ?!? Please tell me I’m thinking of another question.</p>
<p>volume is cut in half, not the height</p>
<p>This question:</p>
<p>Also what was the answer to this questions :
F(x) = ax^3 + bx^2
(i) it has two distinct roots
(ii) it is greater than one
(iii) its range is all real numbers or something like that… </p>
<p>a or b could easily by i, since the only restriction was that neither was 0, so I don’t think III would be correct. I said only I.</p>
<p>@armavirumquecan0
All cubic functions (and F(x) is cubic since a is not 0) approach -infinity in one direction an +infinity in the other (depending on whether a is + or -), so the range is all reals.</p>
<p>This thread has 218 posts but I’ve counted, and we’ve only discussed 8 questions!
- F(x)=ax^3+bx^2 ANS: range is all reals and two distinct zeros (I and III only)
- F(a+1)=-1, F(a)=0,… ANS: -1
- Mean = 74, standard deviation =2 ANS: above the 99th percentile
- Lowest score dropped; 95 on last test ANS: mean (I only)
- Number of times the populations the same ANS: 6
- Cone volume ANS:14.3
- Lowest value of 3+cosA ANS: 3.71
- Number of zeros of f(x)*g(x) ANS: 2, 3, or 4</p>
<p>what did people get for the arithmatic series through (3n+2)?</p>
<p>Btw answer to that 95 added q should me mean and standard deviation both.</p>
<p>Mean cannot change without so changingz</p>
<p>@adi2915
No. Standard deviation could go up or down. See post #150</p>
<p>do we get different test forms?? is that we get different test id’s?</p>
<p>@armavirumquecan0
I can’t remember, but I’ll try it again, if you remind me of the details I’ve forgotten. What I seem to remember was that the first term was 1, the common difference was 3 and you were supposed to find the sum of the first ? terms.</p>
<p>Assuming that I got every single one which we’ve discussed here wrong, (unlikely, I just don’t remember my answers), my score still isn’t that bad.</p>
<p>wait guys stop talking about the test. collegeboard will cancel your scores. ):</p>
<h1>1 was 25/64 or something</h1>
<p>For the one with sinx=.5 and cosx=.5 answer was 150
And for the one with the log pr^2 or something it was 11</p>
<p>@michael2013
I think it was actually 64/25.</p>
<p>@kingsaste
I got 150 degrees, too, for which one cannot be the sum
and 11 for the log one</p>
<p>answer to that sequence thing was 2^16
tan(x) is odd
z = 0 is the set of pts equidistant (0,0,5) and (0,0,-5)
For the time at 60 mph it was (240-80t)/60 = 4 -(4/3)t
Lemme see if i remember more problems…</p>
<p>also 11 for the one about (6n plus or -1) is prime, because 65 is not prime</p>
<p>@kingaste: ditto on those answers
@melzid: oh yeah i remember, youre right</p>
