<p>7/51 here. I also have the x^3 one as inverse.
For the pizza it's 1 + 8nCr2 + 8nCr3</p>
<p>Last question I put down D (probably a mistake)</p>
<p>For the cone I think it was 3.2 because it said like "dimensions" or something like that so I thought both radius and height must decrease (?)</p>
<p>I don't think I got 800. Cancel it is.</p>
<p>what would ~ 5 wrong on the test give? Assuming this years curve is slightly larger than others.</p>
<p>Reasonably difficult. I'm pretty upset that I got a couple of the last questions wrong.</p>
<p>For the cone one, the answer was 3.2 or something like that. I squared the radius and got 2.5 instead. blah</p>
<p>@ Rister, the cone and the smaller cone were supposed to be similar, so the ratios should be the same.</p>
<p>I thought it was easy. 43/50 raw score can be an 800 according to sparknotes.</p>
<p>i think you can skip 7 and still get an 800. 43 raw score = 800. 42 = 790 and so on.</p>
<p>why would you cancel your score just because you didn't get an 800? that's retarded.</p>
<p>The only reasonable explanation I can think of is that he's retaking a 780 or so...</p>
<p>Then again...why bother retaking a 780...</p>
<p>Yeah, I got 92 and 7/51 as well. For the cone one, I solved for the original volume, divided it by two, and solved for the new height (which I assumed to be depth... also, I used the same radius). I think... oh well, I'm sure I got it wrong, anyway. I skipped seven, too (I forgot what the law of sines/cosines formulas were!!!)</p>
<p>Did anyone know how to do the parametric question?</p>
<p>and do you guys think I should cancel my test score cuz I felt really sick today and I ran out of time -__- I skipped 2 and i think i guessed like about 7 which may be probably all wrong... :(</p>
<p>It was so much easier than I expected. Stupid Barrons book got me all worried. </p>
<p>Anyways, why are we discussing the questions?</p>
<p>even if you had gotten them all wrong that's still a 39 raw score, which converts to like 760.</p>
<p>can please someone explain me what a boxplot is?
imagine my emotions when i had to omit an #7ish question and how this boosted my confidence for the rest of the day!</p>
<p>the box and whisker plot? i just subtracted the two end values. i think we learned that in fifth grade so i was like, "what..." </p>
<p>anyways, i think the box accounts for the majority and the whiskers for other extraneous values or something.</p>
<p>box plot....***</p>
<p>do colleges really care if i have like 770 on this thing isntead of 800?</p>
<p>the parametric problem was x^2/9 + y^2/25 =1.
u could have solved one of the equations for 1 and subed it into the other but the calculator can graph parametric equations. Once i graphed it i used the trace feature to find the a and b values of an ellipse. They were 3 and 5.</p>
<p>Can someone explain what the curves do? like for example if the test was a 5+ curve does that mean missing 5 problems will still give a 800 or does it mean missing 43-5/50 (raw score from sparknotes) will give 800 also??</p>
<p>wait, so what are the standard curves like, cause in my PR book it says
50-800
49-780
47-760
46-740
45-730
.
.
42-700</p>
<p>I dont get it. People on this board are saying on their practice test they missed 2 and got 790, or other things.
Is the PR curve a little off, and the real curve a little more advantageous?</p>
<p>If that was the true curve, we would all be screwed.</p>
