Answer: The mean number of checks written per day
Standard deviation
Variance
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-
Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e.
Standard deviation :
Answer:
you have the same quiestion 3 times

Answer:
Volume = 21688.37 in.³
Step-by-step explanation:
Volume of a sphere : V=4/3πr³
4/3π17.3³ ≈ 21688.37025
hope this helps :D
(0,15)(1,45)
slope = (45 - 15) / ( 1 - 0) = 30 mph
