Answer:
46 ft
Step-by-step explanation:
A = (pi)r^2
(pi)r^2 = 1661.06 ft^2
r^2 = 529 ft^2
r = 23 ft
d = 2r = 2(23) = 46 ft
Answer: 46 ft
Answer: b. 1.94
Step-by-step explanation:
For binomial distribution model , the formula to find standard deviation is given by :-

Given : The portability that the offices she visits will eventually purchase her product: p=0.25
The number of offices she visited = 20
We assume that the binomial is an appropriate model for the number of offices that make a purchase.
Then, to find the distance of the possible number of sales Tina could observe from the overall mean number of sales we find standard deviation.

Hence, the correct answer is option (b).
