Answer:

4.75% of the candidates takes more than two hours to learn the computer system.

Explanation:

The relevant information to solve the problem is:

1. The time it takes to learn follows a Normal distribution

2. The mean is 90 minutes

3. The standard deviation is 18 minutes

4. The question is What proportion of candidates takes more than two hours to learn the computer system?

Then, you shall calculate the Z-score and use a standard distribution table to look up the Z-score and the corresponding probability.

Repeating myself from a recent answer, "there are two types of standard distribution tables: tables that show values that represent the AREA to the LEFT of the Z-score, and tables that show values that represent the AREA to the RIGHT of the Z-score".

1. First, calculate the Z-score:

$Z-score=\frac{x-mean}{standard\text{ }deviation}$

$x=2hours=120min$

$Z-score=\frac{120-90}{18}\approx 1.67$

2. Use the table that represents the area to the right of the mean to find the ratio of typists that have a Z-score greater than 1.67.

$Probability=0.0475=4.75\%$

Therefore, 4.75% of the candidates takes more than two hours to learn the computer system.

Operating costs = $7,000 x 5 years = $35,000

Operating costs = $2,600 x 5 years = $13,000

Explanation:

Operating costs = $7,000 x 5 years = $35,000

Operating costs = $2,600 x 5 years = $13,000

The current copier should be replaced. The incremental analysis shows that net income for the five-year period will be $3,000 higher by replacing the current copier.

Assume the government sets a price ceiling, or maximum price800 rent per month Based on the graphwhat will be the outcome of thi

Semmy [17]

The outcome of the ceiling price $800 rent is that the quantity supplied will remains at the same.

<h3>What is a price ceiling?</h3>

This refers to a price order by the government that keeps a price from rising above a certain level known as the “ceiling”.

In the graph, the horizontal line at the price of $800 shows the maximum price set by the rent control law.

The forces that shifted the demand curve to the right are still there, but, at this price, the quantity supplied will remains at the same 15,000 rental units although the quantity demanded is 19,000 rental units.
