The waiting time at which 10 percent of the people would continue to hold is given as 2.3
<h3>How to solve for the waiting time</h3>
We have to solve for X ~ Exponential(λ).
then E(X) = 1/λ = 3,
= 0.3333
Remember that the cumulative distribution function of X is F(x) = 1 - e^(-λx). ; x is equal to the time in over case
For 10 percent of the people we would have a probability of
10/100 = 0.1
we are to find
P(X ≤ t)
= 1 - e^(0.3333)(t) = 0.1
Our concern is the value of t
Then we take the like terms
1-0.1 = e^(0.3333)(t)
1/0.9 = e^(0.3333)(t)
t = 3 * ln(1/0.9)
= 0.3157
Answer:
cut back the expansion of labor as a trade off between higher salaries but fewer workers.
Explanation:
If the employer believes that he is paying above average wages, he will try to reduce labor costs. Since unions are specially good in preventing massive layoffs, the other alternative left for the employer is to not hire new employees, or reduce the number of new employees that he expected to hire.
Answer:
20%
Explanation:
Return on assets is a profitability ratio that shows how much in net income a company is able to generate from its assets.
It is a financial measure that shows the net profit a company is able to generate per $1 invested in assets.
Mathematically,
Return on asset = net income/average total asset
= $800,000/$4,000,000
= 0.2
= 20%
This means that the company's management is a to generate a net income of 20 cents for every $1 invested in assets.
If a government chooses to do this, the reduction in pollution will TAKE PLACE IN THE FIRMS WHERE ITS LEAST EXPENSIVE TO DO SO. If a government desire to establish a marketable permit program, it must first define the pollutants that will be allowed and their overall amounts that will be permissible. Companies that will mostly participate in the program will be those that do not produce much pollutants.
