Answer:
C. There are no shortages or surpluses
Step-by-step explanation:
When an economy is in equilibrium it means that supply meets demand at a specific price and the market clears. If there is a surplus/shortage in supply or demand then there is no equilibrium and the market will not clear.
- surplus = excess supply
- shortage = excess demand
In the presence of a surplus or a shortage there is no equilibrium.
A. No: Demand from customers refers to whether they are willing and able to purchase, one cannot measure if they have "enough" of a good through the equilibrium measure.
B: No: If supply is greater than demand there is excess supply and thus a surplus in the market, therefore not in equilibrium.
D: No: Equilibrium is simply the balance between supply and demand. Even if an equilibrium is efficient, it does not necessarily follow that the allocation and use of resources is efficient as well.
Answer:
chisquare = 31.667
degree of freedom = 2
Step-by-step explanation:
Formula for chisquare test = (O-E)²/E
total number observations= 60 + 25 + 15 = 100
Estimated E,
80% x 100 = 80
15%x100 = 15
5% x 100 = 5
chisquare =

= 5 + 6.67 + 20
= 31.667
from the calculation above the value of the chisquare statistic = 31.67
the degree of freedom is the number of samples in the test n - 1
= 3-1
= 2
I have solve this question also in a tabular form to aid understanding in the file i uploaded.
thank you and good luck!
Answer:
4^6
Step-by-step explanation:
The value of the derivative at the maximum or minimum for a continuous function must be zero.
<h3>What happens with the derivative at the maximum of minimum?</h3>
So, remember that the derivative at a given value gives the slope of a tangent line to the curve at that point.
Now, also remember that maximums or minimums are points where the behavior of the curve changes (it stops going up and starts going down or things like that).
If you draw the tangent line to these points, you will see that you end with horizontal lines. And the slope of a horizontal line is zero.
So we conclude that the value of the derivative at the maximum or minimum for a continuous function must be zero.
