<p>Inverse function problem what did you guys get?</p>
<p>Q: which function is the same as it’s inverse?</p>
<p>It was like </p>
<p>I. something
II. something
III. something</p>
<p>I ran out of time but I put only I…</p>
<p>i put I and III</p>
<p>i think but i know I is 100% correct f(x)= 1/x</p>
<p>but im not sure what III was
II is def. wrong</p>
<p>^Im probably wrong.</p>
<p>What was the height of the cone when the radius and volume of the cone & the sphere are the same?</p>
<p>@Grape I think I got only I too.</p>
<p>you remember what III was?</p>
<p>And what was the standard deviation of the weight of the box?</p>
<p>@Grape for the cylinder thing I forgot what I put, but I think the top part was half the botton part or something. I think I put 1/2 something, but I don’t really remember.</p>
<p>std. dev. was the same</p>
<p>even when you add the 2kg or whatever</p>
<p>Wasnt III something like f(x)=(1/x-1)+1? Im not sure</p>
<p>Inverse function, I and III was correct</p>
<p>The independent probability one, one with 2/3 and 1/3… I put 4/9 as answer.</p>
<p>Yea I think it was. I got I only.</p>
<p>i dont know whatever III was that problem was pretty easy lol</p>
<p>change the x, and y, plug random number, solve</p>
<p>@olaolaolaola - yup i got I and III</p>
<p>damn i put 2/9 i just multiplied</p>
<p>@byahnoob for the deviation one was that 8.4?</p>
<p>Also, do you guys remember the question in inch and asks you to find in feet?
I thought that was harsh, although SAT was made in US…Some might not be familiar with US conversions…</p>
<p>@chachaseeds - whats 8.4 ?</p>
<p>@ olaoalaoaalo dang I put I only</p>
<p>and I also got 4/9</p>
<p>@ byan nvm, I was thinking of something different. What did you put for the deviation one?</p>
<p>for the inches to feet one was it 10?</p>
<p>**** im confused how many inches are in a feet 12?</p>
<p>the deviation was the same for what they gave you 1. something?</p>
<p>No the deviation was 0.1 i think</p>
