A company that produces industrial food processors guarantees that a unit will be replaced free of charge if it fails within 14,000 hours of its first operation. The average number of hours of operation before failure for these units is 16,000 hours with a standard deviation of 1,200 hours. Assume the distribution of hours before failure is approximately normal. a. What percentage of units will have to be replaced free of charge?
b. What percentage of units operate between 14,500 and 17,000 hours before failing?
c. Suppose the company wants to limit the number of replaced units to 1%. What must the average hours of operation before failure be to achieve that goal?

won't that be plagrisim thought?

step-by-step explanation:

answer: c

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
