Answer: The standard deviation of the stock is 3.23 percentage
Explanation:
First we shall calculate the epected weighted average return of the stock.
We shall multiply the probability of the scenario with its expected return and then take the sum of the expected returns of different scenarios,
E(x) = (0.2 x 14%) + (0.7 x 8%) + (0.1 x 2%)
E(x) = 8.6%
We shall use the follwing formula to calculate the Variance of the stock,
σ²(x) = ∑ P(
) × [ - E(r)]²
σ²(x) = (0.2) (0.14 - 0.086)² + (0.7) (0.08 - 0.086)² + (0.1) (0.02 - 0.086)²
σ²(x) = 0.001044
To find the standar deviation,
σ(x) = 
σ(x) = 0.0323109
in percentage it would be 3.23%
Answer:
a.) the economic surplus is greater at the equilibrium quantity.
Explanation:
This is correct because at lower production levels a dead weight is created of the potential surplus that is not obtained either for producer nor consumers. At equilibrium, the maximum surplus is achieved and is allocated among producers and consumers
A $66.50
First take the money she already has from the total.
156-23=133
Then divide this by two. She only needs to save half of this as her parents will match the half she saves.
133÷2=66.5
$66.50
The nations selling the gasoline would be in trouble. They would earn less money and the possibility of a depression like the one the US had under Hoover and FDR would occur.
Answer:
$273.96
Explanation:
The balance will be the future value of $209, at 7% for four years.
The formula for calculating the future value is as below.
FV = PV × (1+r)^n
Where PV is the present value, $209
r= is the interest rate 7% or 0.07
n= 4 years
FV = $209 x ( 1+ 0.07) ^4
Fv =$209 x 1. 310
Fv = 273.9563
Fv= 273.96
