Shoe sizes for men in the united states have a distribution that is bell shaped where = 10 and = 1.5. using the empirical rule, what percent of men have a shoe size between 7 and 13?

after simplifying it i got: -36.25 as my answer. hope that !

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
