An insurance company offers its policyholders a number of different premium payment options. for a randomly selected policyholder, let x = the number of months between successive payments. the cdf of x is as follows: f(x) =0 - x < 10.33 - 1 < x < 30.44 - 3 < x < 40.48 - 4 < x < 60.86 - 6 < x < 121 - 12 < xa. what is the pmf of x? x 1 3 4 6 12p(x)b. using just the cdf, compute p(3 ≤ x ≤ 6) and p(4 ≤ x).p(3 < x < 6) =p(4 < x) =

Step-by-step explanation:

Given that X is the number of months between successive payments

Cumulative distribution function of X is

a) PMF of x would be

b)

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
