PLS HELP ME NOW ITS PYTHAGOREAN THEOREM

rusak2 [61]

Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2

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.

$CV=\frac{S}{\bar X}$

In the case of the first sample you have:

$CV=\frac{0.1252}{1.57}=0.07975$

In the case of the second sample you have:

$CV=\frac{0.1317}{1.72}=0.07657$

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