Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed, with a mean of 50,000 miles and a standard deviation of 12,000 miles. What proportion of trucks can be expected to travel between 38,000 and 62,000 miles in the year? What percentage of the trucks travel less than 35,000 miles in the year? What percentage of the trucks travel more than 57,000 miles in the year? How many miles will be traveled by at least (equal to and more than) 72% of the trucks?

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
