Answer:
Step-by-step explanation:
the a square deck as a whole area is 225
side^2 so 15^2
the circles area is 78.54
area of circle formula= pi(r^2)
if you subtract the circle from the squares area you get the outside.
area of deck= 146.46

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
The frequency stays the same and the wavelength decreases.
