<p>5th term of geo sequence is 6, correct?</p>
<p>^ Correct. </p>
<p>OK, I’m booting myself off this thread lol</p>
<p>i think youre talking about another question and i got -4 for sure</p>
<p>Any other opinions on that stupid x^2<4 problem?</p>
<p>yup. </p>
<p>for the frequency table, wasnt it asking what value of x would give a mean of the frequencies that was a value on the left of the chart? the frequencies were 1, 3, 2, x, 1 and i said x was 3 because the mean would be 2 which was on the left side. idk maybe i misinterpreted.</p>
<p>the curves posted on the sparknotes page make me feel happy. but i doubt collegeboard goes by their curves</p>
<p>3 is the answer mrdoodle</p>
<p>I think for the frequency problem, x would equal 4.
Because then the mean would be 33 divided by 11 which equaled 3… all other values were decimal points.</p>
<p>I think you should be fine mrdoodles. The official sat book shows that you can miss 6 and still get an 800. You can miss 15 (I’m not taking into account the .25 penalty for wrong answers) and still get a 700. That is pure generosity. </p>
<p>Of course, the curve may be somewhat different this time, but the difficulty of the released test in the sat book is comparable to that of the test we just took, so I’m expecting it to be around the same.</p>
<p>ilikebananas i think i know what problem you got but i put a decimal though i was about to put a integer but i didnt</p>
<p>@ rawkfist
Sorry, but I don’t really get what you’re saying?</p>
<p>the one with the table… u pick the number on the left side, which results in a number on the right side which when plugged in the left side gives you too… i think ti was f(f(x))=6 or something and it was like… 2 gives u 3, and then 3 gives you 6… i forgot the exact numbers</p>
<p>if the curve is similar to that of the collegeboard book i’ll be fine. or at least i hope i will. lol</p>
<p>sry bananas i thinkin about another problem LOL
and the mean isnt 33 it would have been 11 with a plugged in 4</p>
<p>xs0itg0esx, i got 2 for that answer.</p>
<p>^ i got the same thing</p>
<p>^^ that doesnt do much for me because i forgot the answers… u solve it the way i did?</p>
<p>yup same way you did and same answer.</p>
<p>-Question that had the table of frequencies and had the frequency of 4 equal x — that should have been “x = 4”</p>
<p>Definetly 3. 1+1+2+3+3 = 10 10/5 = 2</p>
<p>And for the 0<x<pi/2
for sin2xcsc2x
2sinxcosx
(sin2x^2+cos2x^2)^(1/2)</p>
<p>They all work.
Plug in pi/4 for the bottom 2 and the first just cancels itself out.</p>
<p>BTW im at a -3/-4 right now = (. Didn’t see the -q…</p>
<p>For the one about the circle tangent to the axes,
I know it was r=-q but anyone know what letter answer that was? A?</p>
