Question

find the mean of x+2, x+3, x+4, x-2​

Answer 1

Answer:

(4x + 7)/4 is the mean of data

Step-by-step explanation:

mean = sum of all elements/ total no. of elements

 = (x + 2 + x + 3 + x + 4 + x - 2)/4

= (4x + 7)/4

Answer 2

$mean = \frac{sum \: of \: the \: observations}{total \: number \: of \: observations}$

$mean = \frac{(x + 2) + (x + 3) + (x + 4) + (x - 2)}{4}$

$mean = \frac{x + 2 + x + 3 + x + 4 + x - 2}{4}$

$mean = \frac{4x + 7}{4}$
