Question

Find the mean of (x+7) (-x+2)(x - 9) (x+8) (x+1) and (x+3)
​

Answer 1

Answer:

mean of (x+7) (-x+2)(x - 9) (x+8) (x+1) and (x+3)

= 4x + 12 / 6 = 2x + 6 / 3

Step-by-step explanation:

Mean = sum of all the numbers / total no. present

therefore, mean

= (x+7) + (-x+2) + ( x- 9) + ( x+8) + ( x +1) +(x+3) / 6

= 5x -x + 7 + 2 + 8 + 1 +3 - 9 / 6

= 4x + 21 - 9 / 6

= 4x + 12 / 6

= 2x + 6 / 3

Answer 2

Answer:

Step-by-step explanation

Given data = (x +7), (-x +2), (x -9), (x +8), (x +1) and (x +3)

∴Mean = ( Sum of the observations ) / (Total number of observations )

= ( x + 7 - x + 2 + x - 9 + x + 8 + x + 1 + x + 3 ) / 6

= ( 4x + 12 ) / 6

= 2 ( 2x + 6 ) / 6

= 2x + 6 / 3 is the answer.
