With probability 0.7, the toss of an olympic shot- putter travels d = 60 + x feet, where x is an exponential random variable with expected value μ = 10. otherwise, with probability 0.3, a foul is committed by stepping outside of the shot-put circle andwesayd=0. what are the cdf and pdf of random variable d?

step-by-step explanation:

f

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
