Answer:
C. The coefficient of variation is a measure of relative dispersion that expresses the standard deviation as a percentage of the mean, for any data on a ratio scale and an interval scale
Step-by-step explanation:
Th Coefficient of Variance is a measure of dispersion that can be calculated using the formula:
Where 
is the Standard Deviation
and 
is the sample mean
From the formula written above, it is shown that the Coefficient of Variation expresses the Standard Deviation as a percentage of the mean.
Coefficient of variation can be used to compare positive as well as negative data on the ratio and interval scale, it is not only used for positive data.
The Interquartile Range is not a measure of central tendency, it is a measure of dispersion.
Answer:
2, 4 ,6 8
Step-by-step explanation:
Given condition y = 2x
When x = 1 , y = 2 *1 = 2
When x = 2 , y = 2 * 2= 4
when x = 3 , y = 2* 3 = 6
When x = 4 , y = 2 * 4 = 8
Hope it will help :)
Answer:
x = 150
Step-by-step explanation:
What we need to do is first use the sum of interior angles theorem to find the total sum of this odd hexagon.
n = sides of the shape.
(n-2)*180° = Sum of interior angles
For us this would be 720° total. Now make an equation
121 + 96 + 101 +162 + 90 + x = 720
Then we simplify
570 + x = 720
-570 -570
And then subtract 570 on both sides and we get our answer.
x = 150
Basically anything greater than zero...k>0
You can set up a ratio of side lengths as follows:
Now we just solve for x (by cross-multiplying):
So,
x = 75 units.
