Answer:
$10
Explanation:
We are to account for external costs in production, since we are asked to find optimal tax.
Given:
We now have:
A represents number of aluminum units produced, let's find A, since the margnal cost is $30.
Thus,
Let's equate the private marginal cost with the marginal revenue of each unit in order to achieve this amount of produced units with tax, t.
We have:
Substituting 100 for A above, we have:
30 - t = 20
t = 30 - 20
t = 10
Therefore, the socially optimal tax on aluminum is $10 per unit
Answer:
6m/s
Explanation:
Given the information :
an object travels 16 metre in 4 seconds and then another 16 metre in 2second.
what is the average speed of the object?
First portion of travel:
Distance = 16 meters
Time = 4 seconds
Second portion:
Distance = 16 meters
Time = 2 seconds
Speed is calculated as the proportion of distance traveled to the time taken.
Speed = distance / time
First portion :
Speed attained
Distance / time = speed
16 meters / 4 seconds = 4m/s
Second portion:
Speed attained
Distance / time = speed
16 meters / 2 seconds = 8m/s
Average speed :
(first portion + second portion) / 2
(4m/s + 8m/s) / 2
12m/s ÷ 2
= 6m/s

Empowering employees means to provide the training, tools, resources, motivation, and encouragement you workers need to perform at an exceeding level. It is important because it help employees build confidence and a better working community.
Based on the information given in the paragraph above, the measures that fill in the blanks in order are:
- Coefficient of Variation
- Standard deviation
- Expected return
- Risk
When we have an investment with a higher expected return and a higher standard deviation than another investment, we can then base our decision on the amount of risk that we incur per return of the investment.
This measure is called the coefficient of variation and it is calculated thus:
<em>= Standard deviation / Expected return </em>
This will then show you the risk incurred per unit of return. The investment with the lower coefficient is the better one.
<em>In choosing between two investments, if one has the higher expected return but the other has the lower standard deviation, we use another measure of risk called </em><em><u>Coefficient of Variation. </u></em><em>To obtain this measure we divide the </em><em><u>Standard deviation</u></em><em> by the </em><em><u>Expected return</u></em><em>. This measure shows the amount of </em><em><u>Risk</u></em><em> per unit of return...</em>
