Answer:

  • 4. x = 3
  • 5. Number 6 should be included

Step-by-step explanation:

Mean is the average

4.

Data given:

  • 14, 6, 2x, 8, 10, 4

The mean is

  • mean = sum of the data / number of data
  • (14 + 6 + 2x + 8 + 10 + 4)/6 = 8
  • 42 + 2x = 6*8
  • 2x = 48 - 42
  • 2x = 6
  • x = 3

5. Let the added number is x, then the mean is:

  • (2 + 8 + 7 + 4 + 9 + x)/ 6 = 6
  • x + 30 = 36
  • x = 36 - 30
  • x = 6
