The percent of the people who tested positive actually have the disease is 38.64%.
Step-by-step explanation:
Denote the events as follows:
<em>X</em> = a person has the disease
<em>P</em> = the test result is positive
<em>N</em> = the test result is negative
Given:

Compute the value of P (P|X) as follows:

Compute the probability of a positive test result as follows:

Compute the probability of a person having the disease given that he/she was tested positive as follows:

The percentage of people having the disease given that he/she was tested positive is, 0.3864 × 100 = 38.64%.
Answer:
The projected enrollment is 
Step-by-step explanation:
Consider the provided projected rate.

Integrate the above function.


The initial enrollment is 2000, that means at t=0 the value of E(t)=2000.




Therefore,
Now we need to find 


Hence, the projected enrollment is 
Answer:

Answer:
option 5
Step-by-step explanation:
we have diameter=75 feet
