<p>Great. I just couldn’t believe it, I was the antsiest and most nervous that I think I’ve ever been before, and I got a lot of these hard math problems right. There was a cross on the wall in the testing room. = )</p>
<p>I’m positve that the median was 6. Lol/ there were 5 or 6 numbers which had to equal 36 and you divide that by 6 and still get the median.</p>
<p>Might be both; I’m pretty sure it said give one number that could work…could be multiple answers…if only I had the exact question.</p>
<p>i think the median question was 6<x<8 because i got 7.</p>
<p>How cum i didn’t get ANY of these problems???</p>
<p>I think it is 112 too.</p>
<p>what was the median question.</p>
<p>did anyone get the question with a cube in it and a triangular prism is cut out of it and so we have to estimate the fraction of the volume of the prism to the volume of the cube…??? i didn’t know if my answer was right…</p>
<p>3 was definitely an acceptable answer on the median question:
2,7,11,12 were the numbers</p>
<p>i thought you were supposed to provide a number that was the median and also the average. That number would be 8. However, there’s a good chance i misread the question.</p>
<p>no, i thought it said to insert a number where the average happened to equal the median, not necessarily the X</p>
<p>Well, if the numbers were 2 3 x 11 12, 8 would most certainly work. <em>pats self on back</em> Yay.</p>
<p>no hookstra, the mandatory numbers were 2,7,11, and 12</p>
<p>Question read:</p>
<p>set a consists of x 2 7 11 and 12. </p>
<p>for what value of x does the median equal the mean.</p>
<p>In this problem the only numbers that can be the median are 7, 11 or x.</p>
<p>if the median is 7 then the average would be 7 and the sum of all the terms would add up to (5 x 7) = 35. the sum of the known terms is 32. 35-32 = 3</p>
<p>if the median is 11 then the average would be 11 and the sume of all the terms would add up to (5 x 11) = 55. the sum of the known terms is 32. 55-32 = 23</p>
<p>if the median is x then teh average would be x and the sum of all the terms would add up to 5x. the sume of the known terms is 32. x = 4 5x - 32 = 8 . </p>
<p>3 8 and 23 were the only acceptable answers to this question. Done.</p>
<p>^^^^^^was this a grid in or a regular question?</p>
<p>i got 8 for the answer…i dont see how 3 and 23 work tho…</p>
<p>ok nvm i got it lol…but was it a grid in or not?</p>
<p>it was definitely a grid-in (hence the 3 acceptable answers).</p>
<p>I put 3…excellent :).</p>
<p>o yea lol…good</p>
<p>can you get one wrong on CR and still get an 800?</p>
