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:
16x^2 t^5
Step-by-step explanation:
2 * 16 = 32
x * x^2 = x^3
t^3 * t^5 = t^8
2x t^3 * 16x^2 t^5 = 32x^3 t^8
