Question

Find the mean of x+2,x,x-3

Answer 1

MEAN=SUM OF OBSERVATIONS/NO. OF OBSERVATIONS

GIVEN,

1st OBSERVATION=x+2

2nd OBSERVATION=x

3rd OBSERVATION=x-3

NOW APPLY THE ABOVE FORMULA

MEAN=x+2+x+x-3

MEAN=3x-1

THEREFORE MEAN OF THE GIVEN OBSERVATIONS=3x-1

Answer 2

Answer:

$\frac{3x - 1}{3}$

Step-by-step explanation:

Mean =Sum of observations/No.of observations

$= \frac{x + 2 + x + x - 3}{3} \\ = \frac{3x - 1}{3}$
