Coefficient of Standard Deviation vs. Coefficient of Variation: When to Use Each
The standard deviation is most commonly used when we want to know the spread of values in a single dataset.
However, the coefficient of variation is more commonly used when we want to compare the variation between two datasets.
For example, in finance the coefficient of variation is used to compare the mean expected return of an investment relative to the expected standard deviation of the investment.
For example, suppose an investor is considering investing in the following two mutual funds:
Mutual Fund A: mean = 9%, standard deviation = 12.4%
Mutual Fund B: mean = 5%, standard deviation = 8.2%
The investor can calculate the coefficient of variation for each fund:
CV for Mutual Fund A = 12.4% / 9% = 1.38
CV for Mutual Fund B = 8.2% / 5% = 1.64
Since Mutual Fund A has a lower coefficient of variation, it offers a better mean return relative to the standard deviation.
Here’s a brief summary of the main points in this article:
Both the standard deviation and the coefficient of variation measure the spread of values in a dataset.
The standard deviation measures how far the average value lies from the mean.
The coefficient of variation measures the ratio of the standard deviation to the mean.
The standard deviation is used more often when we want to measure the spread of values in a single dataset.
The coefficient of variation is used more often when we want to compare the variation between two different datasets.

5. In one year, there were 125 major new automobile types available. If you look at the miles per gallon (MPG) for these vehicles, the distributions are roughly normal. The means and standard deviations are given by: Mean Standard Deviation City MPG 22.37 4.77 Highway MPG 29.09 5.46 a. The Honda Civic had a rating of 45 highway MPG. What is the probability that your car has a worse highway gas mileage than the Civic? b. The Lincoln Continental had a rating of 17 city MPG. What percent of cars are likely to have a better city gas mileage than the Continental?
Answer:
The answer is "99.82% and 86.99%".
Step-by-step explanation:
In point a:
[tex]=P(X < 45)\\\\= P(Z < \frac{45-29.09}{5.46}) \\\\=P(Z < 2.9139)\\\\=0.9982\\\\=99.82\%[/tex]
In point b:
[tex]=P(X >17)\\\\= P(Z > \frac{17-22.37}{4.77}) \\\\=P(Z > -1.1258)\\\\=0.8699\\\\=86.99\% \\\\[/tex]

Solve for x and show your work! For each equation choose if there are:
• zero solutions for x • exactly one solution for x • or an infinite number of solutions for x.
2(3x + 9) = 18 + 6x
Answer:
Infinite number of solutions
Step-by-step explanation:
Use the distributive property
2 x 3x = 6x
2 x 9 = 18
6x +18 = 18 + 6x
Answer: infinite solution

For each formula,rearrange so a is by itself:
6-9b=3a
6b+2a=3a
a/3=b+2
please explain how to do that i have a test in 2 days
Step-by-step explanation:
a) 6-9b=3a
First:Subtract
3b=3a
Second: Devide
3b/3a
=(3÷3)(b÷a)
=1b/a
= b/a
B) 6b+2a=3a
First:Transpose (Group the like terms. signs will change.)
-3a+2a=-6b
=-1a=-6b
Second:Divide
=-1a/-6b:(-1÷-6)(a÷b)
=1a/6b
=a/6b
C)a/3=b+2
First: Transpose
a=3+2+b
=a/6+b
does anybody know the answer?

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?
Answer:
100 Candy Bars
Step-by-step explanation:
Hey!
==================================================================
Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?
--------------------------------------------------------------------------------------------------------------
We can create an algebraic Equation to solve this.
- We know that Each Candy Bar costs $1.50.
-We multiply the Amount of Candy Bars with the price.
-We know the profit should be $150
⇒ 1.50x = 150
-Divide by 1.50 on both sides
⇒ 1.50x/1.50 = 150/1.50
-Simplify
⇒ x = 100
==================================================================
Hope I Helped, Feel free to ask any questions to clarify :)
Have a great day!

what is the product of x and y values 2x+8y=24 -7x-6y=26
Answer:
x= -8
y=5
Step-by-step explanation:
2x + 8y =24
2(x+4y)=24
x+4y=24/2
x+4y=12
x=12-4y
-7x-6y=26
-7(12-4y)-6y=26
22y-84=26
22y=26+84
22y=110
y=110/22
y=5
x=12-4y
x=12-4×5
x= -8

Step-by-step explanation:
If f(x) = x2 and g(x) = 3x + 1, then g(f(2))= ?
Answer:
The value of g[f(2)] = 13
Step-by-step explanation:
Given functions:
f(x) = x²
g(x) = 3x + 1
Find:
The value of g[f(2)]
Computation:
f(x) = x²
By putting x = 2 in f(x)
f(x) = x²
f(2) = 2²
f(2) = 2 × 2
f(2) = 4
So the value of f(2) = 4
Value of f(2) putting in g(x)
g(x) = 3x + 1
g(x) = 3x + 1
g[f(2)] = 3[f(2)] + 1
We know that f(2) = 4
So,
g[f(2)] = 3[f(2)] + 1
g[f(2)] = 3[4] + 1
g[f(2)] = 12 + 1
g[f(2)] = 13
The value of g[f(2)] = 13

2. What is the coordinate of the final image of vertex T
after the triangle is translated 3 units to the left and 2
units up?
Please help with number 2
Answer:
We have the coordinates of vertex T after the translation as (-5,0)
Step-by-step explanation:
Firstly, we get the coordinates of vertex T
we have this as;
(-2,-2)
Translating to the left means we are going to subtract the specific units from the x-coordinate
2 units up means we are going to add to the y-coordinate value
So, we have it that;
(-2-3, -2+ 2) = (-5,0)
If 4 children drink 24 ounces of milk everyday then how much do they drink in a week? (if this shows up twice sorry i didn't know)
Answer:
168
Step-by-step explanation:
24x7=168
Answer:
In total, the amount of milk every kid combined drank is 672 ounces.
Step-by-step explanation:
If four kids drank 24 ounces of milk for seven days, you would solve it as follows:
First, the amount all the kids drink in one day combined is 96 ounces.
If they drink 96 per day, and they do so for a week (7 days), then that is 96 × 7 because its 96 seven times.
7 × 96 = 672
