The following data give the hourly wage rates (in dollars) of eight employees of a company 23 23 23 23 23 23 23 23 on Calculate

cupoosta [38]

Answer:

0 because they are the same

Step-by-step explanation:

The average of this the hourly wage is

μ = (23 + 23 + 23 + 23 + 23 + 23 + 23 + 23)/8 = 23

The standard deviation would then be

$\sigma = \sqrt{\frac{\Sum (x - \mu)^2}{n}} = \sqrt{\frac{(23 - 23)^2 + (23 - 23)^2 + ... + (23-23)^2}{8}} = \sqrt{\frac{0}{8}} = 0$

The value is indeed 0 because all the hourly wages are the same (23) and there's no deviation from the average

What is y - 2 = 3(x – 7) written in standard form?

$y - 2 = 3(x - 7)$

$y - 2 = 3x - 21$

Add sides 2

$y - 2 + 2 = 3x - 21 + 2$

$y = 3x - 19$

Subtract sides 3x

$- 3x + y = - 3x + 3x - 19$

$- 3x + y = - 19$
