Answer:
0.9792
Step-by-step explanation:
Data provided in the question:
Average gross sales = $1,240
Standard deviation = $180
sample size = 40
Now,
standard deviation of sample average
=
=
= 28.46
Now,
z value for 1200 =
= -1.4,
and,
p value for (z = -1.4) = 0.0808
therefore,
P(average < $1200) = 0.0808
Thus,
probability that the average over the next 40 weekdays will exceed $1,200
= 1 - 0.808
= 0.9792

Answer:
The length of the cover that will wrap around the edge of the trampoline is 43.96 ft.
Step-by-step explanation:
Given that,
Area of trampoline, 
Jeena wants to buy a cover to put around the edge of the trampoline. We need to find the length of the cover that will wrap around the edge of the trampoline. First of all, lets find the radius of trampoline. Let is is r. So,

To find the length of the cover that will wrap around the edge of the trampoline we will find circumference of the trampoline as :

So, the length of the cover that will wrap around the edge of the trampoline is 43.96 ft.
