Cars arriving for gasoline at a shell station follow a poisson distribution with a mean of 9 per hour. a. determine the probability that over the next hour, only one car will arrive. probability = b. compute the probability that in the next 6 hours, more than 22 cars will arrive.

Step-by-step explanation:

Given

Poisson Distribution with mean of 9 per hour

Mean of Process

Probability that over the next hour , only one car will arrive

Probability is given by

For k=1 and t=1

(b) For next 6 hours , more than 22 cars will arrive will be given by

k=22, t=6 hr

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
