If the mathematics scores of the SAT college entrance exams are normal with mean 480 and standard deviation 80, and if some college sets 520 as the minimum score for new students, what percent of students would not reach that score?

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.
