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?

sine

step-by-step explanation:

your answer   is c

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
