garrett is removing a hem from a skirt. It takes garrett 5 min to remove 4 in of the hem. He wants to know how long it will take to remove 5 ft of the hem if he continues to work at the same rate. How can Garret determine how long it will take to remove 5 ft of the hem?

first you take the 4 in and if you multiply that by three you get a foot, then you know that it takes him 15 min to remove a foot, so you multiply 15 by 5ft, and that equals 75 min = 1 hr 15min

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
