Answer:

B. historic return over long time periods.

Explanation:

Variance is a metric applied in statistics to determine the squared deviation of a random variable from its mean value.

The variance of a return of investment is a measure of the historic return over large time periods. The historical return approach is more commonly used in the exercise of investing. It follows the data which is a finite set of historical returns of investment and assumes that each possible result has an equal probability.

Suppose that the market for athletic shoes is initially in equilibrium at point A. Further suppose the demand for athletic shoes

elixir [45]

Answer: Correct. When there is an increase in supply and an increase in demand, the new equilibrium quantity increases but whether the equilibrium price increases or decreases is unknown.

Explanation:

When the demand for the shoes increased, it had the effect of shifting the demand curve to the right. At the same time, with six more firms coming into the market, the supply increased as well which had the effect of shifting the supply curve right as well.

The new equilibrium as a result of these movements will see the quantity increase. However, due to the shift of both the supply and the demand curve in the same direction, it is uncertain if the price will change or not.

The general rule is that if the rise in supply is more than rise in demand then the price will decrease. If they rise by the same amount then price will remain the same. It shows therefore that if both supply and demand rise at the same time, the effect on equilibrium price is unknown.

Answer: $11,620

Explanation:

A=P(1+r/n)^nt

A=$10,000(1+0.03/12)^12×5

A=$10,000(1.0025)^60

A=$10,000(1.162)

A=$11,620

A metallurgist has one alloy containing 26%26% copper and another containing 69%69% copper. How many pounds of each alloy must h

Brilliant_brown [7]

Answer:

Ans. He must use 2,987.76 pounds of alloy X (Cu=69%) and 2,365.24 pounds of alloy Y (26%=Cu)

Explanation:

Hi, let´s call alloy X the alloy that contains 69% of Cu and alloy Y the one containing 26% of Cu. Since he needs to produce 5,353 pounds of alloy, the first equation that we need to use is the following.

$X+Y=5,353$

Now, we need this 5,353 pounds of the new alloy to be 50% Cu, therefore, we have to use a portion of alloy X and alloy Y. This is as follows.

$0.69X+0.26Y=0.5(X+Y)$

And we have already established that X+Y is equal to 5,353, therefore this equation should look like this.

$0.69X+0.26Y=5,353*0.5$

$0.69X+0.26Y=2,676.5$

And we solve for X this equation, this as follows.

$0.69X=2,676.5-0.26Y$

$X=\frac{2,676.5-0.26Y}{0.69}$

$X=3,878.98-0.3768Y$

Now, we use this result and substitute this for X in the first equation like this.

$3,878.98-0.3768Y+Y=5,353$

and then, we solve for Y

$0.6232Y=5,353-3,878.98$

$Y=\frac{1,474.02}{0.6232} =2,365.24$

So, he needs to use 2,365.24 pounds of alloy that contains 26% of Cu, this means that the rest (2,987.76 pounds) must come from the alloy that contains 69% of Cu.

We can check this result by finding the overall Cu obtained by this amounts of alloy, that is

$Coppper FromX=2,987.76*0.69=2,061.55$

$Coppper FromY=2,365.24*0.26=614.96$

That adds up to 2,676.51 pounds of pure Cu, and since the total weight of the new alloy is 5,353, this amount of copper makes up for:

$PercentCu=\frac{2,676.51}{5,353} =0.5$

50% of the total weight.

Best of luck.

andrey2020 [161]

In the given example, the $8000 represents median of central tendency. The median is the number in the middle of a sorted, ascending or descending list of numbers, and it can be more descriptive of the data set than the average. It is the point above and below which half (50%) of the observed data falls, and thus represents the data's midpoint.

The median is the number in the middle of a sorted list of numbers. To find the median value in a series of numbers, sort the numbers in value order from lowest to highest or highest to lowest. The median can be used to approximate an average or mean, but it should not be confused with the actual mean.
