Answer:
$375
Explanation:
A stock you own earned: $200, $500, $100, and $700 over the last four years.
We need to find the annual gain in value over the four years. We know that,
Mean = sum of observations/total no. of observations
Put all the values,
So, the required mean annual gain is equal to $375.
Answer:
attached is the diagram
Explanation:
Each extra worker produces an extra unit of output, is said to be the marginal production of an extra worker employed
marginal production :
change in total production / change in labor = ΔTp / ΔL
Average production = Tp / L
Tp = total production , L = number of labor
To draw the Total product of labor , average product labor and marginal product labor curves starting from zero labor
0 worker : Total product = 0, average product labor = 0 , marginal = 0
1 worker : Total product = 1, average product = 1 , marginal = 0
2 worker : Total product = 2, average product = 1, marginal = 1
3 workers: total product = 3 average product = 1, marginal = 1
4 workers: Total product = 4, average product = 1, marginal = 1
5 workers : Total product = 5 average product = 1, marginal = 1
6 workers : total product = 6 average product = 1 , marginal = 1
7 workers : total product = 7 , average product = 0.85, marginal = 0
8 workers : total product = 8, average product = 0.75 marginal = 0
