<p>bestmorn, that was definitely experimental section. I don’t recall having that s a last question.</p>

162

<p>jammer, you do not need to simplify.</p>

<p>30/4 is right.</p>

163

<p>I don’t remember that question, bestmorn.</p>

164

<p>wasn’t the primes 3+7=10?</p>

165

<p>NOOOO!</p>

<p>I think I put 1/4 instead of 1/9 for the section about the x/y one…</p>

<p>I think I misread it as Y being 3 different integers being less 10, not 20</p>

<p>FFFFFFFFFFFUUUUUUUUUUUUUU-</p>

166

<p>Was the answer to the question about which triangle was largest the choice in the second column, second row?</p>

167

<p>@sunshower</p>

<p>The problem said there was no prime number in between. 5 is a prime in between 3 and 7.</p>

168

<p>what was the one about a 1 inch and 1.25 inch and something like 6.5 inch</p>

169

<p>silverturtle, it was the one where the right triangles had legs that were the radii.</p>

170

<p>

</p>

<p>Difference between the primes had to be 4 and there could not be a prime number between the two.</p>

171

<p>doughboy:
i know the slope of the line of best fit was positive, but because they added “the slope, in dollars per distance” it made me think we had to find the slope of the dollar/distance rate (which wasnt graphed)</p>

172

<p>what was the one about a 1 inch and 1.25 inch and something like 6.5 inch </p>

<p>6.25 inches. Or 6 and a quarter. I think…?</p>

173

<p>Can someone explain the four routes through F question?, I got that you could take the bottom and there were two other ways, but I remembered that the top route didn’t work.
Somebody explain this? bump</p>

174

<p>“1/9 smallest value of x/y”</p>

<p>WHAT?!?!?! Why? I thought x could be 1,2,3 and y could be 17,18,19. No?</p>

<p>EDIT: Ohhhh waitttt sorry I put mine in decimal form and it just threw me off haha. Whew.</p>

175

<p>6/54 = 1/9</p>

176

<p>^ that produces 6/54 or 1/9</p>

177

<p>There’s not much to explain for that one, KanyeRice.</p>

<p>You can go up right down down right, or right down right, or down up down right, or down right right.</p>

<p>…if that helps.</p>

178

<p>silverturtle, I think that was the answer… it was only question #2, so the answer must have been easy.</p>

179

<p>Also I am not sure the one of 0 is the remainder. I think I put 5 for that one…
Can anyone explain???</p>

180

<p>8 inch page-1 inch margin-1.25 inch margin = 6.25 inches of text.</p>
