<u>The value of the expression is -35.</u>
<u>Step-by-step explanation:</u>
<u>Consider the provided expression.</u>
<u>3x + y </u>
<u>We need to find the value of the expression for x=13 and y=−74 .</u>
<u>Substitute the value of x=13 and y=−74 in the above expression as shown:</u>
<u>3 (13) + (-74)</u>
<u>39 - 74 </u>
<u>-35</u>
<u> the value of the expression is -35.</u>

Answer:
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%.
