Assume a Poisson random variable has a mean of 8 successes over a 112-minute period. a. Find the mean of the random variable, defined by the time between successes.
Mean
b. What is the rate parameter of the appropriate exponential distribution? (Round your answer to 2 decimal places.)
Rate parameter
c. Find the probability that the time to success will be more than 66 minutes. (Round intermediate calculations to at least 4 decimal
places and final answer to 4 decimal places.)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

yes

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
