<p>i put 4 years because it asked when it went over 6 million people. and it could be 3 years (say, february) and it would still be under 6 million. but idk.</p>
<p>How do some people already know their raw scores?</p>
<p>Did anyone get the matrix question or the one about the standard deviation from the mean?</p>
<p>@horusb231 i omitted both haha. i asked my friend later and he said standard deviation was 0. I never learned standard deviation in any of my math classes from middle school up to now.</p>
<p>i omitted 4, and i got 1 wrong. i hope that’s enough for an 800.</p>
<p>@supersoaker101 i got just x for the abs value question
@horusb321 i put 0 but i had no idea what a normal distribution graph was</p>
<p>i skipped the
standard deviation from mean
cos phi = -cos theta, sin phi = sin theta
matrix question
&
the combination/permutation problem on picking a group of 3 people
anyone know the answer to these?</p>
<p>Anyone get the one with system of equations and the 2</p>
<p>There was also a question about range and the “normal mode” was 8. What does that even mean. Another question was about g(x) was something and f(x) had a period of 2 and f(x) = g(x). You had to find f(9/2)</p>
<p>Combination permutation answer was 11!/(8!3!)</p>
<p>What was the one with the equation that “went in” or something if all real numbers worked as the range or something? I said the linear equation but idk…</p>
<p>range from was 7.</p>
<p>comibnation/permutation problem was 11!/3!8!</p>
<p>the f(9/2) was the last one i omitted. i worked out -45/4 but i wasn’t confident so i left it blank</p>
<p>@tiffax. it was pi - theta.
@fakeperson. i got the same thing.</p>
<p>@fakeperson123 i did not get the 2x2 matrix
@horusb231 the range was 7. the numbers went like this, 1,3,5,8,8. i did not get the period question. </p>
<p>overall i still think this test was harder than barrons which is supposed to be super hard</p>
<p>@rokr. I got -45/4 but it seemed too simple for a question that was numbered 40 something…</p>
<p>f(9/2) was 0.75 i believe</p>
<p>@siddg911 good! thanks I was just checking.</p>
<p>I thought the answer was π/2-theta…</p>
<p>@siddg. how did you know the last two were 1 and 3? for example, why isn’t it 2 and 2?</p>
<p>@horusb231 because it said the mode was 8
if it were 2 and 2 then 8 wouldnt be the only mode</p>
<p>oh okay. thanks! could you explain the f(9/2) one?</p>
