At Mama’s Country Kitchen, they serve mashed potatoes and country fried steak. The average amount of mashed potatoes put on the plate is 4 oz. with a standard deviation of 0.2 ounces. If they decided to double their servings of mashed potatoes on each plate, what would be that standard deviation of a total of 10 servings of mashed potatoes? a) 4
b) 10.24
c) 0.64
d) 3.2
e) 1.6

A

Step-by-step explanation:

If the standard deviation for the original serving is .2, and they doubled the size, then the deviation would become .4. Then you multiply that by the ten servings to make 4.

f

step-by-step explanation:

f

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
