A - 5.1 = 1.7
a = 1.7 + 5.1
a = 6.8

-31 = z + (-17)
-31 = z - 17
- 31 + 17 = z
z = -14

A-5.1=1.7
+5.1 on both sides
a=6.8

-31=z+(-17)
+17 on both sides.
-14 = z

Which one of the following is always true?a. The coefficient of variation measures variability in a positively skewed data set r
Tom [10]

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:

CV = \frac{\sigma_{x} }{\mu_{x} } * 100%

Where \sigma{x} is the Standard Deviation

and \mu_{x} 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.

Solve by substitution x-y=-11 y+7=-2x
Bess [88]

x - y = - 11   .............( 1 )

y + 7 = - 2x ...............( 2 )

from equation ( 1 )

x - y = - 11

x   = -11 + y  ...........( 3)      

putting x in equation  ( 2 )

y + 7 = - 2 x  

y  + 7 = -2 ( -11 + y )             y + 7 = 22 - 2 y                       y + 2 y =22 - 7            

3 y = 15                  y = 15 / 3

putting value of y in equation 3

x   = -11+ ( 13 /5 )                       x = -33 /3 + 15 / 3         ( l.c.m)

x  = -17 / 5                      

check      

x = -11 + y

- 17 / 5 = -11 + 13 / 5

-17 /5   = -17 / 5
