<p>"also is that sq.root of t and t question a part of a parabola..??"</p>

<p>Yup.</p>

<p>how did everyone get 37.5</p>

<p>also wht bout this slope question.. -1 right??</p>

<p>"thanks nervous... 3/10.. how???"</p>

<p>50 percent of the cars are white. 30/50 cars are two-doored. Probability of white and two-doored: (Probability of white car)*(Probability of white car with two doors) = (1/2)(3/5) = 3/10.</p>

<p>Let me know if that's the wrong way to do it.</p>

<p>by just making the required changes in the formula of the cylinder pi<em>r</em>r*h...</p>

<p>1.25^2 x 1.5 x 16 = 37.5</p>

<p>"how did everyone get 37.5"</p>

<p>I chose numbers and got that, but someone on the previous page explained that you just multiply 16 by 1.5 and something else (check a few pages back.)</p>

<p>And yeah, the one with the two slopes multiplied is -1.</p>

<p>nervous its 30 % of those 50% right.. and 30/50..</p>

<p>oh crap! i forgot to square it...ugh</p>

<p>what about the bloody questions with those rectangles and their areas.. didnt ahve time for that one.
also some other statistic question abut adding numbers in a list.. is that 5??</p>

<p>"nervous its 30 % of those 50% right.. and 30/50.."</p>

<p>Are you sure it 30 percent and not 30 out of 50? (and 3/5 is = 30/50 :P)</p>

<p>"also some other statistic question abut adding numbers in a list.. is that 5??"</p>

<p>Yeah, 5 and 5, I got.</p>

<p>maybe i don't remember the question correctly, but i thought it was 50% white, 30% whatever door...so, 1/2*3/10=3/20.</p>

<p>i could be wrong though...that seems to be the trend with me today.</p>

<p>that what i got too</p>

<p>I can't remember exactly either Chandra. Well no use arguing it :P If it was 30/50 (without the percent), then it's 3/10. Otherwise, it's another answer (don't wanna work it out now, lol).</p>

<p>I'm positive that it was 30% and 50%, so there!</p>

<p>For areas of rectanges, I plugged in the x's (like, if the right corner was at 8, i plugged in 8) and got the y values for the height of each rectangle. Then, I multipled each of those y values by 2, and added them together.</p>

<p>lol ya.. no use arguing... what about a question in the beginning of test whr v gotta find length of a side using sine rule.. wt did u get there.. i think i got 8.something..</p>

<p>can any one tell me what wer the last 2 questions on the test??</p>

<p>I got...something like that...we found it pretty simple so didn't pay it much mind.</p>
