Answer:
d. Equilibrium price will increase, equilibrium quantity will decrease"
Explanation:
"Ceteris paribus" all things being equal; the higher the price, the lower the quantity demanded. If there are speculations about possible increment in price of wheat in near future time, it will result into panic buying of wheat in the market today and that will definitely increase the equilibrium price of the wheat and decrease the equilibrium quantity of wheat demanded.
Answer:
$42
Explanation:
Data provided as per the requirement of contribution margin per hour of machine time is here below:-
Unit Contribution Margin = $21
Machine Time required by fancy lamp = 0.50 hours
The computation of contribution margin per hour of machine time is shown below:-
Contribution Margin Per Hour of machine time = Unit Contribution Margin ÷ Machine Time required by fancy lamp
= $21 ÷ 0.50 hours
= $42
Therefore for computing the contribution margin per hour of machine time we simply divide the unit contribution margin by machine time required by fancy lamb.
Answer:
Variance = 0.02141851
Explanation:
We first calculate the mean for the stocks
Mean = (0.1858 - 0.0558 + 0.2081) / 3
Mean = 0.3381 / 3
Mean = 0.1127
Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1
Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2
Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2
Variance = 0.04283702 / 2
Variance = 0.02141851
The variance of returns is 0.02141851
The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample (
) = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) = 
= 
= 
= 11
Hence the standard deviation is equal to 11.
