<p>stop changing the subject!!! i agree with grojos –> if anyone remembers any part of the question then we can put everything together and solve it. i personally remember that Choice II stated that plane Q was parallel to both planes M and N. and the question said that planes M and N intersected line R. that is what i am 100% sure about.</p>
<p>ill use abc for simplicity</p>
<p>Question 50:
If planes A, B, and C exist in space with lines x, y, and z and line x intersects planes A and B but not C, which of the following could be true?</p>
<p>Now lets confirm answer choices and rule stuff out</p>
<p>Answer choice III said that plane Q was parallel to either M or N but not both. <~ I’m pretty positive. </p>
<p>BTW guys do you think it’d be okay if i accidentally used the second page of the answer sheet to do my math 2 subject test instead of the 1st page (the page with the cursive disclaimer)? I only took 1 subject test so would the machine like not read it or soemthing…</p>
<p>@xAlex452 Right, choice III said its parallel to either of them. I can confirm for 110% that the answer for that question was I and III. II did not work because it was impossible. Also, did anyone else have a hard time with the two stat problems? Those were the only 2 i omitted, but besides that, I think I answered everything else correctly. Im hopping for an 800 
:)!!!</p>
<p>if Q was parallel to either plane, then it would have intersected line r right?</p>
<p>man, I give up on comparing answers.</p>
<p>Also, for the 2k+1 question, I believe the answer is the one with 15 in it. This is so because the statement said that the equation produces a prime number for every integer (k), and since 15 is not a prime number, it has to be the answer.</p>
<p>what was the answer to the one which a bunch of variables and asking which one would divide the result by two?</p>
<p>did it say the planes intersected AT the lines or if the lines were separate?</p>
<p>@gmarch89 I think the answer to that one was two statements, the two that didn’t include divide c by 2.</p>
<p>I think it was AT the lines . . .</p>
<p>For the 2k+1 (were k is an int.) yields a prime question - - - -
wouldn’t a counterexample be that 2 is prime?</p>
<p>@Education so that would be divide e by 2 and multiply f by 2 or something like that?</p>
<p>so far compiled:
“For the prime number one, I put the “2 is a prime number”” shouldn’t it be 2(7) +1 = 15, which is not a prime be right?
180 n^k question was 30
0.32 for lake county
F(x) = g(x)(x-2) +r was f(2)

Double of one root in the equation x^2 - 24x + c (c was 128 I think) -> 16 (the answer), other root was 8

Last question is III and I</p>
<p>@Ivycraze for the prime question that’s what I thought at first too but if you read the question it says which disproves the fact that a prime can be written as 2x +1. 2(7) +1 = 15 simply demonstrates that you can write a composite as 2x+1. It doesn’t prove that a prime CANNOT.</p>
<p>On the other hand, 2 is a prime disproves that fact because 2 cannot be written as 2x+1 (because x is then 1/2, which is not an integer)</p>
<p>What’s quadratic regression? I’m not good with my calculator so I just guessed 5.2.</p>
<p>For the root question, was it x^2+24x+c or x^2-24x+c cause I answered -8 when I got roots, -8 and -16</p>
<p>What is this even mean. f(x) = g(x)(x-2) + r
I had guessed f(0) cause I thought that r would just be the constant value of a polynomial. But now, rereading the problem, I think it’s f(2) cause then all the g(x)(x-2) would become 0.</p>
<p>Thanks.</p>
<p>^I got -8 too. Everyone else seems to be getting 16, though. We’re probably wrong.</p>
<p>And for the last problem, the answer was I and III. I’m sure. We already went over this earlier in the thread.</p>
<p>For quadratic regression, I just used STAT feature and got 4.9 for the root
For f(x) = g(x)(x-2) + r, f(2) = r (like you said.)
Oh, the root question was x^2 - 24x + c</p>
<p>To clarify…the question near the end…i think it was number 48…sin2x>sinx is wrong??</p>
<p>the root question was x^2-24x+c and I thought it would be (x-8)(x-16) factored. 8 wasn’t an answer, so 16 had to be the answer
also, any curve predictions? 43, 44, or 45 for 800?</p>
