After recording the pizza delivery times for two different pizza shops you conclude that one pizza shop has a mean delivery time of 46 minutes with a standard deviation of 4 minutes the other shop has a mean delivery time of 44 minutes and a standard deviation of 18 minutes interpret these figures if you'd like the pizzas from bull shoals equally well which one would you order from and why

I would order the pizza from first shop because it has lower standard deviation and in this way i will know when the pizza will delivered.

Step-by-step explanation:

Mean time taken by first pizza shop is 46 minutes with standard deviation of 4 minutes it means this shops deliver a pizza in 42 to 48 minutes

on the other hand mean time taken by second pizza shop is 44 minutes with standard deviation  of 18 minutes it means this shops deliver a pizza in 26 minutes (44-18) to 62 minutes (44+18)

I would order the pizza from first shop because it has lower standard deviation and in this way i will know when the pizza will delivered.

2/25

Step-by-step explanation:

4 green marbles, 6 blue marbles, 8 yellow marbles, and 2 red marbles. = 20 marbles

P( green) = green/total = 4/20 = 1/5

Replace the marble

4 green marbles, 6 blue marbles, 8 yellow marbles, and 2 red marbles. = 20 marbles

P(yellow) = yellow/total = 8/20 = 2/5

P(green, replace, yellow) = 1/5*2/5 = 2/25
