Answer: <u><em>Miles ran by Matt = 6 miles</em></u>
Step-by-step explanation: Miles ran by Stan = 4 7/10
i.e. 1 3/10 miles less than Matt.
∴ Miles ran by Matt = 4 7/10 + 1 3/10 = 60/10 = 6miles
∴<u><em> Miles ran by Matt = 6 miles</em></u>

1m=100cm
85 cm
400 mm=40 cm
Add up them up and you get 225 cm in total

Answer:
The mean of the total repair time is 150 minutes.
The variance of the total repair time is 725 minutes^2.
Step-by-step explanation:
To solve this problem, we have to use the properties of the mean and the variance. Our random variable is the sum of 3 normal variables.
In the case, for the mean, we have that the mean of the sum of 3 normal variables is equal to the sum of the mean of the 3 variables:

For the variance, we apply the property for the sum of independent variables (the correlation between the variables is 0):

208 ÷ 13 = 16, so her rate is $16 per hour. Through guess and check,
Kira would have to work 11 hours to make $176.
