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 : 
You have to move both decimals over and then divide. So the answer is 25.
Answer:
Number of gallons of strawberries will she have picked in 2 hours is, 3
Step-by-step explanation:
Unit rate defined as the rate are expressed as a quantity of 1, such as 4 feet per second or 6 miles per hour, they are called unit rates.
Given the statement: Jen picked 3/4 of a gallon of strawberries in half an hour.
⇒ In 
hour Jen picked 
gallon of strawberries.
Unit rate per hour = 
To find the number of gallons will she have picked in 2 hours.
=
Therefore, the number of gallons will she have picked in 2 hours is, 3
