Question

If the mean of five observation
X, X, +4x+6,x+8andx+12is 16​

Answer 1

Answer:

x = 10

Step-by-step explanation:

$mean \: = \frac{sum \: \: of \: \: observation}{no . \: \: of \: \: observation} \\ \: 16 = \frac{(x) + (x + 4) + (x + 6) + (x + 8) + (x + 12)}{5} \\ 16 = \frac{5x + 30}{5} \\ 16 \times 5 = 5x + 30 \\ 80 = 5x + 30 \\ 5x = 80 - 30 \\ 5x = 50 \\ x = \frac{50}{5} \\ x = 10 \: \: \: ans$
