Suppose pages per book in a library have an unknown distribution with mean 297 and standard deviation 25 pages. a sample of size n=75 is randomly taken from the population and the sum of the values is taken. using the central limit theorem for sums, what is the standard deviation for the sample sum distribution?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

is there more to this question?
