Ralph likes 25 but not 24;400 but not 300;144 but not 145; does he like 10,50,124,200, or 1600

Likurg_2 [28]

25, 400 and 144 are all square numbers and 24, 300 and 145 are not.

Therefore, he must like 1600

What is TR (915)- TR (895)=

tangare [24]

The result is TR (20).

To determine the result of TR (915) - TR (895), the following logical-mathematical reasoning must be made:

We find a constant that is repeated in both values, which is TR.

In turn, both values have a different quantity, which multiplies that constant.

Therefore, you must perform this multiplication and then subtract the results, to obtain the final result.

TR (915) - TR (895) = X
915TR - 895TR = X
20TR = X

Therefore, the result is TR (20).

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.
