Listed below are amounts (in millions of dollars) collected from parking meters by a security service company and other companies during similar time periods. do the limited data listed here show evidence of stealing by the security service company's employees? security service company: 1.4 1.6 1.7 1.6 1.5 1.6 1.6 1.5 1.4 1.8 other companies: 1.5 1.8 1.6 1.9 1.7 1.9 1.8 1.7 1.7 1.6 find the coefficient of variation for each of the two samples, then compare the variation.

The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.

Step-by-step explanation:

The coefficient of variation of a sample is defined as the ratio between the mean standard deviation and the sample mean. And it represents the percentage relation of the variation of the data with respect to the average.

In the case of the first sample you have:

In the case of the second sample you have:

The relative variability is almost equal in both samples a slight greater variability can be noticed in the first sample.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

good luck on ur quiz test or homework. have a good day : )
