Answer:
$1023.98
Explanation:
Using the standard notation equation for annual payment and for arithmetic gradient to calculate the present worth of a unit's costs; we have the following corresponding expression.
P = A (P/A, i, n) & P = G (P/G, i, n)
where;
A = annual payment
G = arithmetic gradient
n = number of years
i = annual interest rate
From the question;
the payment period = compounding period
∴ quaterly interest rate = 3%
The present worth value of the unit's cost is therefore shown as
P = 90 (P/A, 3%, 12) + 2.5(P/G, 3%, 12)
P = 90(9.954) + 2.5(51.2481)
P = $1023.98
∴ The present worth value of the unit's cost = $1023.98
I am not entirely sure what a performance test is, but I can help with the others. A polygraph is a machine, used usually if you are in legal trouble, to see if you are lying. While results aren't 100% accurate, you typically can get a gage for if someone committed a crime. They are also rarely used for interviews, some companies want to see if people are lying on their resumes. Drug tests are tests that are given to most people with a job, and especially sports players. Companies especially like to test people for drugs, to see if they might be on an illegal drug that could cause them to work less efficiently. It also is a liability issue for the company if an employee is on an illegal drug. Drug tests are typically done at a lab, and you usually have to pee in a cup and have it get tested.
The probability that both item is defective are 3.84%
The probability that the second is defective is 20%
<h3> What is the probability that both items are defective?</h3>
a) Remember that the question says they are drawn without replacement
hence
(20/100)*(19/99)
= 19/495
= 0.03838383
= 3.84%
b. What is the probability that the second item is defective?
(20/100)*(19/99) + (80/100)*(20/99)
= 0.03838383 + 0.1616
= 0.199999
= 0.2
= 20 percent

Answer: This implies that the cross elasticity of demand between orange juice and apple juice is <u>0.5.</u>
Explanation:
The cross elasticity of demand is evaluated as:

Price of orange juice increased by 20 percent, which resulted in a 10 percent increase in the quantity of apple juice consumed.
The cross elasticity of demand 
The cross elasticity of demand = 0.5
Hence, This implies that the cross elasticity of demand between orange juice and apple juice is <u>0.5.</u>
