How many computers: in a simple random sample of 125 households, the sample mean number of personal computers was 1.02. Assume the population standard deviation is = 0.7. Construct a 99.8% confidence interval for the mean number of personal computers is?

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
