Answer:

-x^3(x - 3)(x + 3).

Step-by-step explanation:

-x^5+9x^3

the greatest common factor = x^3 so we can write it as

x^3(-x^2 + 9)

= -x^3(x^2 - 9)

The expression in the parentheses is the difference of 2 squares so we have:

-x^3(x - 3)(x + 3)   Answer.

Answer:

x^3(-x+3)(x+3)

Step-by-step explanation:

-x^5 + 9x^3

factor out x^3

x^3(-x^2+9)

9 and -x^2 are perfect squares so we can factor out a 3 and an x to get (-x+3)(x+3)

the fully factored form would be x^3(-x+3)(x+3)

Question 2 -
atroni [7]

Coefficient of variation, CV. for Data set A is 13.5% and for Data set B is 19.6%

Sample A: 2.94, 3.06, 3.07, 3.16, 3.34, 3.43, 3.47, 3.56, 3.57, 3.97, 3.99, 4.24, 4.30, 4.35

Mean = 3.6036, Standard deviation = 0.4858.

C.V = \frac{S.D}{Mean}

=\frac{0.4858}{3.6036}

=0.1348

=0.1

Sample B: $24,800, $30,000, $22,300, $20,400, $19,000, $32,200, $23,000, $23,000, $24,000, $27,200, $34,900

Mean = 25527.2727, Standard deviation = 5001.218.

C.V = \frac{S.D}{Mean}

=\frac{5001.218}{25527.2727}

=0.1959

=0.2

In terms of percentage, C.V for sample A is 13.5% and for sample B is 19.6%
