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 :
2 1/2 for $6.25 is the answer
Answer:
(x-7)^2+(y-8)^2=121
Step-by-step explanation:
The answer is 4,162 for 564+3,598
Angle a is 35 degrees angle b is 55 degrees angle c is 110 degrees
