<p>does anyone remember the f(n)=1/ squart root of (n-1000) question?</p>

<p>Wait… the sock one was what?</p>

<p>i cant remember the question but i put i and ii too.</p>

<p>@CrazedOutBoy: I’m on.</p>

<p>mifune can you answer the questions i posed 2 pages earlier? (about the point -1,1 and k - 5) please?</p>

<p>what was thee answer to the one like
I. (a-b)c - (z+a)
II.z(a-c)+d(a+B)
III, a-b + cz </p>

<p>something along thoe lines
i put II and III
did anyone else get this?</p>

<p>i got II and III</p>

<p>Hmm, I didn’t have half of these questions. There must have been two different versions.</p>

<p>that was the answer about the number of faces on a cube?</p>

<p>Sock question guys… what did you put? </p>

<p>I think I got more wrong than I thought dammit.</p>

<p>x and y could be the same numbers. The question didn’t say they were two different integers.</p>

<p>i think it was two acrosstheuniverse</p>

<p>Sock question = 4</p>

<p>CrazedOutBoy,</p>

<p>The answer was k-2 for that question. k-5 wasn’t an option.</p>

<p>I am not sure what your second question was referencing. Can you restate it? Was it the slope question about the point from (2,4) to somewhere between 0 and 1 on the y-axis? You are not referring to the parabola question, are you? The answer there was (1,3).</p>

<p>Wow this thread is confusing. Did they have diff. versions for sure?</p>

<p>@CrossTheUniverse: Why 4? To ensure a pair from completely random drawings, you need to draw 7 times since there were 6 socks of each color.</p>

<p>I thought there were 3 socks. There goes the 800.</p>

<p>No, I am positive that there were 6. Could someone substantiate this?</p>

<p>from tbonus </p>

<p>“4 socks to get a pair”</p>

<p>It was 4. There are 3 different colored socks with 6 in quantity for each. In order to obtain a proper pair, they must be the same color. This means you can get 3 socks at maximum without reaching a proper pair.
I think you misinterpreted it mifune. The answer would only be 7 if it must ensure a pair of socks that are not the same color.</p>
