How do I solve the following equation? A certain car model has a mean gas mileage of 34 miles per gallon (mpg) with a standard deviation 3 mpg. a pizza delivery company buys 59 of these cars. what is the probability that the average mileage of the fleet is greater than 33.8 mpg?

The probability that the average mileage of the fleet is greater than 33.8 mpg is 0.695

Step-by-step explanation:

The car model has a mean gas mileage of 34 miles per gallon (mpg) with a standard deviation 3 mpg. We want to find the probability that the average mileage of the fleet is greater than 33.8 mpg, if a pizza delivery company buys 59 of these cars.

We calculate the z-score using:

We substitute

From the standard normal distribution table, P(X>33.8)=0.695

the answer to this question is 3/19

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
