Amy was scheduled for 12 intervals this week. One her first interval, she had a technical issue that prevented her from working
ad-work [718]

Based on the total of intervals vs the number of intervals Amy attended her CA percentage is 75%

<h3>What is the CA percentage?</h3>

The CA percentage measures the commitment of an employee to be logged in during the intervals that were assigned to him/her to work.

In this way, the CA percentage is equal to 100% if the employee worked as scheduled. Moreover, this percentage can be affected by factors such as:

  • Technical issues.
  • Human errors.

In the case of Amy, there is a total of 12 intervals and it is known:

  • She had a technical issue that prevented her from working, but this was reported so it is unlikely this is considered in her CA.
  • She missed three intervals because she looked at her schedule wrong.

Based on this information, let's calculate her CA:

  • 12 intervals = 100%
  • 9 intervals =  x

  • x = 9 x 100 / 12
  • x = 900 / 12
  • x = 75%

Answer:

The answer is 10x² - 4x.

Step-by-step explanation:

You have to apply Distributive Law,

a(m + n) = am + an

So for this question :

2x(5x - 2)

= 2x(5x) + 2x( - 2)

= 10 {x}^{2}  - 4x
