Suppose that iq scores have a bell-shaped distribution with a mean of 98 and a standard deviation of 13. using the empirical rule, what percentage of iq scores are less than 59? do not round your answer.

i think the answer would be c

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

it will take 9 minutes
