<p>This is a hypothetical question:</p>
<p>Suppose all the math sections on my SAT were a total of 10 questions.
I skip 5 of the 10 questions.
I do the 5 questions that I did correct.
Is my score still a 100% or is it graded 5/10 ?</p>
<p>Amit Max: it's 5/10. It seems a common misconception when people hear the deduction rule is that it's deducted from the full score, when in fact it's deducted from your score.</p>
<p>Basically, If you answer 9 out of 10 and get them all correct, your score is 9. If you answer 10 out of 10 and one is wrong, your score is 8.75.</p>
<p>how bout this one if F(x + y) = F(x) + F(y)
and a = b, which of these is true</p>
<p>I. F(a+b) = 2F(a)</p>
<p>II. F(a + b) = [F(a)]squared</p>
<p>III. F(b) + F(b) = F(2a)</p>
<p>is it just I or I and III?</p>
<p>I & III</p>
<p>f(b) + f(b) = f(b+b) (reversed the rule) = f(a+a) = f (2a)</p>

<p>***For the inverse proportion one, isn't x = ky, so x2 = (y^2)k, then (1 / x2) = (1 / y2).. i put (1 / y2) for the answer.</p>
<hr>
<p>it was y^2, x = 1/y</p>
<hr>
<p>The circle problem they gave you the radius, so I ended up getting 6pi for my answer. I got it down to 5pi and 6pi or w/e the answers were, then I got the area of the two small semi circles and it had to be greater than 5pi and less than 7pi, 6pi . Originally I got it down that it had to be less than 7pi, but there were two that worked 5pi and 6pi... so just get other parts of the circle and see what they come out to then it has to be greater than so and so.</p>
<hr>
<p>yes, 6pi was correct</p>
<hr>
<p>The Teddy Roosevelt question was already correct, so I put A. They tried to trick you with answer D or whatever it was, but they had ", also and" I believe.</p>
<hr>
<p>yeah i got A as well, that was an annoying question for sure</p>
<hr>
<p>There was that octagon question which asked how many triangles form inside the octagon. Each angle had to be 45 degrees, because it said all the sides and angles were equal so 360/8 = 45. I just said there were 8 triangles in the octagon, I hope that was right (basically a basketball figure).</p>
<hr>
<p>they asked you to draw diagonals from one vertex and then count the resulting triangles (answer was 6)</p>
<hr>
<p>There was one problem, I think it was either 14 or 16, which was REALLY easy addition, the 1+1+1+1+2 problem I think. I may have gotten this wrong, but I still filled in whatever I thought was right. It just seemed odd this question came up.</p>
<hr>
<p>yeah that question was really random. testing our addition skills i guess...</p>
<hr>
<p>The problem with the series of numbers multiplied by -2, I skipped, can I get an explanation for this? It was -2, 8,... and I forgot the rest of the series.</p>
<hr>
<p>basically, the first 6 numbers were less than 100, and then of the remaining 44, half were negative and therefore less than 100. 22+6=28</p>
<p>damn, im -3 so far</p>
<p>Do you guys know if there was sa Math Experimental Section. I had two math sections in a row and could have sworn I took an extra math 25 min section. I heard it isn't the one with the finding of the yin yang shapes/circles.</p>
<p>arent there 3 math ones anyway?</p>
<p>What was the answer to the one where it gave you F(x) and asked you about G(x). It said G(x) = F(3X+1) and asked for G(2). Wouldn't that just shift the graph one to the left and make it 0 or was it F(3(2)+1) = F(7) and whatever the value was at F(7)?</p>
<p>Elliot34, I had that soap question, too. (Section 3, I believe? Which I THINK was the experimental.)</p>
<p>I got 5.5 for the answer. There were 90 six ounce and 30 four ounce, so when you average it out, it comes out to 5.5. At least, I think so!</p>
<p>polka and elliot, that must have been experimental</p>
<p>ehighmark - yes, it was the answer at F(7)....-5? i forget but yeah thats what it was</p>
<p>Nate you sure that's right. I'm pretty sure when you are graphing those you first shift the graph and then stretch it. So the graph would shift to the left one (making it 0) and then multiply by 3, still making it 0. Otherwise I agree with you. If you remember on the last sat there was a question similar about shifting one to the left.</p>
<p>There was a question stating integers s > w, asking for the difference between the sums of s+t and s+w. Or something like that. What was the answer? I think I picked C.</p>
<p>the answer was s-w or one of the answers which includes a - in it.</p>
<p>It would just be s - w right? Random ex: t = 10, w = 5. s = 20</p>
<p>(10 + 20) - (5 + 20) = 10 - 5</p>
<p>Hmm. Anyone remember which letter that was? A, C, or D? eurgh, sorry if these questions are annoying.</p>
<p>oh gosh i remembered now! there was also a question like this
3y=2x+c, one of the coordinates was (5, -1)
whats c???
please help D=</p>
<p>I remember it was like 3x + 2y = c or whatever, both x and y on the same side. I just plugged the coordinate in.</p>
<p>omfg i fergot i can plug the numbers in...............................
i fail.</p>
<p>ehighmark - yeah i'm sure. f(3x+1) just means you plug (3x+1) in for x in the equation, so you plug in 7, so that's essentially x. if it had been f(3x)+1 that would have been different.</p>
