Here all employees get equal amount as bonus, so the standard deviation of the employees income won't change. 
if you subtract or add equally to all the data then standard deviation won't change but mean and median would change.

hope this help

<h2>            <u>Rectangular</u> <u>Areas</u> <u>and</u> <u>Perimeters</u></h2>

The perimeter of a rectangle is given by:

\boxed{\bold{Perimeter = 2 (length + width)}}

In the problem we have these data:

  • Length = a
  • Width = -2x + 20
  • Perimeter = 6 + 2 (-2x + 20)

We replace the data in the equation of the perimeter:

<h3>6 + 2 (-2x + 20) = 2 (a - 2x + 20) </h3>

We apply distributive property:

6 - 4x + 40 = 2a - 4x + 40

6 = 2a

6 ÷ 2 = a

3 = a

⇒ Length = 3

The area of ​​the rectangle is given by:

\boxed{\bold{Area = 2 (length + width)}}

We have these data:

  • Length = 3
  • Width = -2x + 20

We replace the data in the equation of the area:

<h3>Area = (3) (- 2x + 20) </h3>

We apply the distributive property and obtain:

Area = -6x + 60

<u>The expression representing the area of ​​the rectangle will be -6x + 60</u>

<h3>I hope I've helped!</h3>
