The area would be about 83.14.
You can find this by starting with the formula for the area of an equilateral triangle:
A =
In this equation, A is the area and S is the side. So we'll just plug in the value.
A =
A =
A =
A = 83.14

Answer:
(a)P(x>85.55)=0.02275
(b)
Step-by-step explanation:
We are given that
Average sales for an online textbook distributor per customer per purchase
,$67.63
Standard deviation of the amount spent on textbooks,$8.96
(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.
=
=
=
P(x>85.55)=0.02275
(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase
