Yes it’s a function and for every hour the fee will go up .50
First divide bot sides of the formula by 1/2(3.14):-
2A / 3.14 = r^2
r = sqrt (2A/3.14)
Answer:
A = 153.94 sq mi
Step-by-step explanation:
In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following
A = 
A = 
A = 
A = 153.94 sq mi
A total of 153.94 square miles must be searched.
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.
