Question

Find the mean of x, x+2, X+4, X+6, X+8.​

Answer 1

Answer:

the answer of the question is x+4

Answer 2

Answer:

x + 4

Step-by-step explanation:

mean = sum of all observations / number of observations

there are 5 observations

so mean = ( x + [ x + 2 ] + [ x + 4 ] + [ x + 6 ] +[ x + 8 ] ) / 5

= (  x +  x + 2  +  x + 4  +  x + 6  + x + 8  ) / 5

= ( 5x + 20 ) / 5

= 5 ( x + 4 ) / 5

= x + 4

therefore the mean of the observations x, x+2, X+4, X+6, X+8.​ is x + 4
