<p>I got 0 for that</p>
<p>Im so mad at myself! I wrote 80=.5x for the last grid in and got 160 
i hate thissss</p>
<p>Anyone know what the SA was for the cube i put 51 but i think it was 54</p>
<p>Are you guys sure its 0? I worked it out. The median is 10.5 and the mean is 11. </p>
<p>54 is correct for the cube SA question</p>
<p>yeahh I worked it out also, I added up 1-21 but then I realized that it was 22 terms and by that time I already circled 0.5 but I quickly erased it and just left it. Crapp but 0 makes so much sense, god dammit i messed up so much on thisss test. Just stupid mistakesss due to time, I havent done a math practice section in awhile (B/c of CR) so my time management was horrible :(. Crap oh well, maybe I can super score with my november one DAmmmm</p>
<p>Were these questions experimental:</p>
<ol>
<li><p>A question about a triangle, it was one of the very last problems #18,19,or 20. It asked you to find the AREA, and I think it said that it was an equilateral triangle… not the perimeter question( I had the perimeter question in another section).</p>
<ol>
<li>A question about a cone or cyliner within a larger cone or cylinder. The question asked what fraction the volume of the smaller cylinder or cone was that of the larger one… one had a side length 5, one had side length 10… both had different heights… both had same hypotenuse </li>
<li>60 percent of class were girls, class was 40 percent of school, how many students in school?</li>
<li>If list has contains n numbers, the numbers are either 3 or 5, and the mean is 4… What could be a possible value for n? ( roman numberals I, II, III) </li>
<li>something like x^(2/3)y^1/2 and you had to get it to equal x^3(y) … so you had to square both sides to get the answer</li>
</ol></li>
</ol>
<p>I worked it out and got 11 for both because the median was 11 and i added them all up and divided by 21 and got 11 for the mean.</p>
<p>22 terms?..there’s 21…counting 1 to 21 is 21 numbers…right?</p>
<p>In addition, was the question x + y + z < 270 experimental?</p>
<p>no that wasn’t cause i had it</p>
<p>Did anyone get 0 for the question about yellow, wrinkled seeds??</p>
<p>I see what I did…but, Archu, how is 1-21 22 terms?</p>
<p>X +Y+Z <270 is correct</p>
<p>Did anyone get the question about reflection of a point? it was no.20 or was that experimental?</p>
<p>Niquii77, I also got 0 for the median v. mean question. I worked it out twice. The first time I got .5, but I later realized that its 0</p>
<p>it waaaas 0
i checked it twice and again</p>
<p>if you simplify it, its a basic principle of averages of all odd collections of consecutive numbers</p>
<p>0,1,2
median is 1, mean is one</p>
<p>2,3,4,5,6
median is 4, mean is 20/5=4</p>
<p>It’s a mathematical principle that the difference will be 0.</p>
<p>It was (-1,3)</p>
<p>****kk you’re right!! hahaha. I told you it wasn’t a good day for me. haha well at least I wont get docked for it I hate myself right noww</p>
<p>@Philo that makes me feel a lot better that I erased my answer</p>
<p>Did anyone know the answer that went like f(a) =f(b) or something like that it was 2 lines on a graph and that made an X symbol</p>
