According to Mr. Bock, 67% of all students at LHS play sports. Suppose we are interested in the proportion of the 100 students in the East Atrium play sports. (a) Is the normal approximation to the proportion pˆ = r / n valid? Explain.

(b) What is the probability that the proportion of those in the East Atrium who play sports is at least three fourths?

(c) What is the probability that the proportion of those in the East Atrium who play sports is no more than 60%?

(d) What is the probability that the proportion of those in the East Atrium who play sports is between 60% and 75%?

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
