Answer:

Step-by-step explanation:

here you go mate :)

step 1

2(x + 4) = -6 solving for x

step 2

2(x + 4) = -6 simplify by distributing

2x+8=-6

step 3

2x+8=-6 subtract 8

2x=-14

step 4

2x=-14 look for the number that can divide them both like 2

2x/2=-14/2

answer

x=-7

Find the average rate of change for f(x) = x2 + 9x + 18 from x = −10 to x = 10. A) 3 B) 7 C) 9 D) 11

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 10, 10 ], thus

f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208

f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus

average rate of change = $\frac{208-28}{10-(-10)}$ = $\frac{180}{20}$ = 9

The hourly wages of a sample of 130 system analysts are given below.

atroni [7]

Answer: b. 30%

Step-by-step explanation:

A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. $CV=\dfrac{\sigma}{\mu}$

Given: mean = $\mu=90$

Variance = $\sigma^2 = 729$

$\sigma=\sqrt{729}=27$

Now, $CV=\dfrac{27}{90}=0.3$

in percent , $CV= 0.3\times100\%= 30\%$

Hence, correct option is b. 30%.
