Answer:
29.97 square feet
Step-by-step explanation:
Given
The length of rectangle = 9 ft
The width of rectangle = 40 in
We have to bring the length and width in same unit. As the area is required in square feet so we will convert width in feet
The width will be divided by 12 to be onverted into feet
So,
Width = 40/12 = 3.33 feet
Now
Area = Length * width
= 9 * 3.33
= 29.97 square feet ..
You should take into account that the radius is half the diameter and the diameter is the length from the side to side of a circle.

Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The population proportion is 
The mean of the sampling distribution is 
The sample size is n = 600
Generally the standard deviation is mathematically represented as

=>
=>
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as

=> 
Now add p to both side of the inequality
=> 
=> 
Now converting the probabilities to their respective standardized score
=>
=> 
=> ![P(|p-\^{p}| > 0.03) = 1 - [P(Z \le 2.88) - P(Z \le -2.88)]](https://tex.z-dn.net/?f=P%28%7Cp-%5C%5E%7Bp%7D%7C%20%3E%20%200.03%29%20%20%3D%20%20%201%20-%20%5BP%28Z%20%5Cle%202.88%29%20-%20P%28Z%20%5Cle%20-2.88%29%5D)
From the z-table

and

So
![P(|p-\^{p}| > 0.03) = 1 - [0.9980 - 0.0020]](https://tex.z-dn.net/?f=P%28%7Cp-%5C%5E%7Bp%7D%7C%20%3E%20%200.03%29%20%20%3D%20%20%201%20-%20%5B0.9980%20-%200.0020%5D)
=> 
All you are really doing is if you divide you are moving the decimal to the left and when you times you are moving the decimal to the right
