Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 265 feet and a standard deviation of 35 feet. Let X be the distance in feet for a fly ball. a. What is the distribution of X? X ~ N(,)

b. Find the probability that a randomly hit fly ball travels less than 270 feet. Round to 4 decimal places.

c. Find the 85th percentile for the distribution of distance of fly balls. Round to 2 decimal places. f

3(2x-5)-x=-7(x+3)

6x-15-x=-7x-21

5x-15=-7x-21

5x+7x=-21+15

12x=-6

x=-(6/12)

Therefore, x=-(1/2)
