Answer:
The surface area of the cube is 96 squared unit.
Explanation:
The surface area of a cube is the addition of the area of each surfaces. The surface net of the cube illustrates that it has 6 squares of 4 unit length each.
So that,
Area of a square = length × width
But, length = width
⇒ Area of a square = 
= 
= 16
Area of one of the squares of the cube is 16 squared unit.
Surface area of the cube = number of squares × Area of one of the squares of the cube
= 6 ×16
= 96 squared unit
The surface area of the cube is 96 squared unit.
Answer:
Combined Beta = 1
Combined return = 10%
Explanation:
given data
stock portfolio = $50,000
beta = 1.2
expected return = 10.8%
beta = 0.8
expected return = 9.2%
standard deviation = 25%
to find out
combination
solution
we get here first Combined Beta that is express as
Combined Beta = 1.2 × 50% + 0.8 × 50%
Combined Beta = 1
and
Combined return will be here
Combined return = 10.8 × 50% + 9.2 × 50%
Combined return = 10%
Answer:
d. 0; unrelated.
Explanation:
Cross elasticity of demand is the degree of responsiveness of demand for a particular product to a change in the price of another product.
A change in price of a product will lead to a change in demand for another product if the two goods are either goods of close substitutes or if they are complements. If two goods are not related, the change in price of one will not have any impact on the demand for the other good.
In this question, the cross elasticity is zero because biro and pencil are not related.
Answer: Decrease
Explanation:
According to the Law of Demand, The quantity demanded for purchase of a commodity inversely varies with the price.
That is to say that "ceteris paribus" ( with everything being equal),When the prices of a particular good go higher, people will buy less of such commodity but will buy more, if the prices of the goods reduces.
We can say demand is elastic if quantity demanded for a commodity decreases with increase in price which will make people choose another lower substitute good eg, detergent, ice cream
Also if quantity demanded does not change much with increase in price , then it is referred to as Inelastic Demand for example necessity commodity such as gasoline.
