Vikentia [17]

Answer:

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

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

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

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.

A spinner with 9 equal sections is numbered 1 through 9. The probability of spinning a 1 or a 9 is 2/9 . What is the probability

shtirl [24]

The probability of NOT getting a 1 or a 9 means you have to subtract those two numbers and how many of each are out. Once you do that, count the remaining numbers, put them as the numerator, and then put the overall total of numbers as the denominator. Your answer is 7/9.

Find the exact solution of -x2 +7x + 5 = 0 by using the Quadratic Formula.

jonny [76]

Answer:

The answer to your question is:

x 1 = -0.65

x2 = 7.65

Step-by-step explanation:

Equation -x² + 7x + 5 = 0

a = -1

b = 7

c = 5

Quadratic formula x = -b ±√(b² -4ac) / 2a

x = - 7 ± √(7² -4(-1)(5) / 2(-1)

x = -7 ± √(49 + 20) / -2

x = -7 ± √69 / -2

x = - 7 ± 8.3 / -2

x1 = -7 + 8.3 / -2 x2 = -7 -8.3 / -2

x 1 = -0.65 x2 = 7.65
