<p>please explain probability and parabola question</p>
<p>what was the 2x question???</p>
<p>@^ False</p>
<p>For the median to have been 88 degrees, 88 would be the temperature of the 7th day.</p>
<p>Those of you who got 93, did you re-order the numbers first?</p>
<p>Can anyone confirm 5/x=4 with x/10 being 1/8? and something with 2x/7 being 2? I don’t remember the second problem specifically but I just remembered those two.</p>
<p>I confirm with SlightManifesto. You must order the numbers in order to get 88 as the median.</p>
<p>Crazy: Yes to the first one. Not sure about the second.</p>
<p>^ Crzy, I got those answers too.</p>
<p>the school question. anybody have the exact wording?</p>
<p>I got difference of 9 for something.</p>
<p>i thought the school question said determine the difference of the avg number of increase in students in two schools and there was a graph</p>
<p>please explain probability and parabola question</p>
<p>what was the 2x question???</p>
<p>@sententia difference of 9 for the perimeters of the similar triangles. Might have been experimental though, I’m not sure.</p>
<p>@SLightManifesto: I am 100% positive I reordered the numbers. It gave temps for 6 days, 80, 82, 83, 90, 91, 93 (something like that and not in order) and said that the temps were recorded for 7 days with 88 being the median. so in order it would be: 80, 82, 83, 88, 90, 91, 93. The 7th day would be 93. Anyone confirm?</p>
<p>2x question was experimental.
Difference of 9 was not experimental.</p>
<p>cookie: No. The question asked what the 7th day temperature would be in order for the median to be 88.</p>
<p>y = x^2 + kx + 15</p>
<p>vertex = (4,-1)</p>
<p>-1 = 4^4 + 4k + 15
-32 = 4k
k = -8</p>
<p>y = x^2 -8k + 15
y = (x-5)(x-3)</p>
<p>Thus answer is (5,0)</p>
<p>Difference of 9 in the two perimeters of the similar triangles.</p>
<p>To cookiemonster: I think you are incorrect. The first 6 numbers were the numbers of the first 6 days, and because 88 is the median, but was not included in the list of numbers for the first 6 days, it had to be the 7th day’s temperature.</p>
<p>The other question with the two functions, where they said f(x) = x + k and g(x) = xk should have been 6</p>
<p>cookiemonster, the 7th day was 88 not 93. Remember it said that they already had recorded the first 6 days. The temperate your added (the 7th day) was 88.</p>
<p>difference was 9, it wasn’t experimental</p>
<p>How about the question with the greatest change in number of votes from 2002 to 2004. I put the letter with the coordinates (10, 40)</p>
<p>It was B for the 2002-2004 votes.</p>
