<p>The painter was only walls and ceiling, for q49. the box and wisker plot, was 50% choice c, anyone know?</p>

<p>edit: nvm i counted wrong</p>

<p>I skipped 9, what do you think the max score I can get is?</p>

<p>one question was asking - if f(1/x) = x, what is f(x) ???</p>

<p>if you at least got about 45 of the questions right you will get 800</p>

<p>“one question was asking - if f(1/x) = x, what is f(x) ???”</p>

<p>I put 1/x</p>

<p>They gave 10 and said to find 99. Didn’t even do the problem lol.</p>

<p>A10.</p>

<p>I changed it into a geometric sequence to solve, and that’s how I remember.</p>

<p>yea…im pretty sure it was A</p>

<p>i got 1/x as well</p>

<p>Can someone explain that f(1/x)=x one? I’m pretty sure I got it wrong.</p>

<p>i did what klaften did and got -2-2i :frowning: i dun remember what was the 10th term (it was given) :(</p>

<p>\fghgfhgfjghjghj</p>

<p>

f(1/x) = x
1/(1/x) = x</p>

<p>f((g(x))= x
g(x) = 1/x</p>

<p>f(x)=?</p>

<p>If it equals x again means it’s the inverse of g(x)</p>

<p>g(x)= 1/x
y= 1/x
x = 1/y
y= 1/x</p>

<p>Wow! I totally misread the painter one, and I used .00092 instead of .0092 for the population one! I think that just about ends any hopes of a 800 :(</p>

<p>Spratley, if I’m not wrong the curve is 3 wrong or 2 wrong 2 skip for an 800. :&lt;/p>

<p>“stop worrying about what the actual answer was… it was the 10th term multiplied by i (the 11th term). if you didnt know that, you got it wrong.”
what was the 10th term</p>

<p>im so mad because i left a few blank that i knew the answers for. the time just seemed to go really fast. does anyone have an idea of my score range if i left 8 blank? how will the curve be?</p>

<p>can we please look at some harder questions? how come every1s asking for answers to the easier ones?</p>
