We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.
To find the area of community pool we will use area of pentagon formula.
, where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.
Let us find the perimeter of our given pentagon by multiplying each side length by 5.
Now let us find apothem of our pentagon by using Pythagoras theorem.
Upon substituting our given values in above formula we will get,
Therefore, the area of the pool that needs to be covered is 960.42 square feet.
Answer:
21/40
Step-by-step explanation:
2 5/8 / 5 =
= 2 5/8 / 5/1
= 21/8 × 1/5
= 21/40
B pretty simple need in depth let me know
Using the Central Limit Theorem, the percentage that is expected to be the closest to the actual percentage is:
A. The Tribune, at 68%.
<h3>What does the Central Limit Theorem state?</h3>
It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean 
and standard error 
, as long as 
and 
.
From this, a larger sample size leads to a smaller error estimate. Since the Tribune had the largest sample size, option A is correct.
