The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:
Simplified:
To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
Answer:
COV (all stocks) = 0.55
COV (stocks and bonds) = 0.82
Step-by-step explanation:
Coefficient of Variation is used to measure variability.
It is defined as the ration of standard deviation and the mean.
It can be used to compare variability of two population or two samples.
Formula:
where are data points,
is the mean and n is the number of observations.
x: 14, 0, 39, 25, 32, 27, 28, 14, 14, 15
y = 6, 2, 29, 17, 26, 17, 17, 2, 3, 5
Since coefficient of variation of x is less compared to y, thus it could be said bonds does not reduce overall risk of an investment portfolio.
