For this case we have to:

Where:
a: It's the Dividend
b: It is the Divider
c: Is the Quotient
Thus, the expression "the quotient of 5 and x" can be represented as:

Where "y" is the quotient of 5 and x.
ANswer:

Answer:
Mean = 15
Standard deviation = 1.94
Step-by-step explanation:
We are given the following information:
We treat favoring of building a police substation as a success.
P(Success) = 75% = 0.75
Then the number of citizens follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 20
We have to find the mean and the standard deviation.

Thus, the mean of favoring the substation is 15 and the standard deviation of favoring substation is 1.94
Answer:
