Cars arrive at a toll booth according to a Poisson process with mean 70 cars per hour. Suppose the attendant makes a phone call. How long, in seconds, can the attendant's phone call last if the probability is at least 0.5 that no cars arrive during the call

35.6 seconds

Step-by-step explanation:

The Poisson distribution has a probability model that follows the given relationship:

For x = zero calls at a probability of 50%, the arrival rate during the call is:

Since cars arrive at a rate of 70 per hour, the length of call 'n' in seconds is:

The call should be at most 35.6 seconds long to ensure a 50% probability that no cars arrive during the call.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
