Answer:
C) An increase in the price of tennis racquets
Explanation:
If tennis racquets become more expensive, the demand for them will decline, and people will try to supply this need with substitutes, for example, lacrosse raquets. The reason for this is that the classical supply and demand model tells us that demand and price are inversely correlated: if the price goes up, demand goes down, and viceversa.

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: False
Explanation:
Mr. Garcia should not accept the planner's ideas without critical evaluating the point the planner gave when he was discussing with him.
