An automobile service facility specializing in engine tune-ups knows that 45% of all tune-ups are done on four cylinder automobiles, 40% on six-cylinder automobiles, and 15% on eight-cylinder automobiles. Let number of cylinders on the next car to be tuned Required:
a. What is the pmf of X?
b. Draw both a line graph and a probability histogram for the pmf of part (a).
c. What is the probability that the next car tuned has at least six cylinders? More than six cylinders?

answer:   2 multiplied by x =24

step-by-step explanation:

false

inverse variation is not exponential

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.
