In a family of five children, there is a 25% chance that each individual child has freckles. Children inherit freckles independently of one another. Let X represent the number of children in this family with freckles. What are the mean and standard deviation of X? Mu Subscript x Baseline = 1.25, Sigma Subscript x Baseline = 0.97
Mu Subscript x Baseline = 1.25, Sigma Subscript x Baseline = 0.94
Mu Subscript x Baseline = 1.5, Sigma Subscript x Baseline = 0.19
Mu Subscript x Baseline = 2.5, Sigma Subscript x Baseline = 0.97

mean: 2.7

standard deviation: 0.6

Step-by-step explanation:

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
