Step-by-step explanation:
36*(3/4)
I just put that in a calculator so
Average speed is given by total distance traveled divided the total time taken.
Given that the distance from Mason's home to their son's college campus is 154 miles, then a round trip (to and fro) <span>from their house to their son's college campus will be 2 * 154 = 308 miles and the journey took 5 and a half hours.
Therefore, the average speed is given by:

Answer:
The probability distribution of the number of customers that enter the store on a given day is:

Step-by-step explanation:
To calculate a parameter for the given day, we have to calculate what is the average arrival rate for the day.
This can be done with the data given:
1) From 10 to 12, 8 arrival/hour: 16 expected arrivals in this period
2) From 12 to 2, 8 to 12 arrival/hour (average: 10 arrivals): 20 expected arrivals in this period.
3) From 2 to 5, from 10 to 4 arrival/hour (average: 7 arrivals): 21 expected arrivals in this period.
The total expected arrivals in a day are: 16+20+21=57 arrivals/day.
Then, the probability distribution of the number of customers that enter the store on a given day is:

A I think is the right answer
