Question

If the average of the values 18,41,25,36,x,24,37,35,27,36,is x find the value of x ​

Answer 1

Answer:

31

Step-by-step explanation:

(18+41+25+35+24+37+35+27+36+x)÷10=x (no. of the values=10)

(279+x)÷10=x

279+x=10x

279=10x-x

279=9x

x=279÷9

x=31

Answer 2

Answer:

X=31

Mean = 18, 41, 25, 36, X, 24, 37, 35, 28, 36

No of observations = 10

Mean = sum of observations / no of observations

Mean => 18 + 41 + 25 + 36 + X + 24 + 37 + 35 + 28 + 36 / 10

X = 279 + X / 10

X = 249 + 10X

10X - X = 279

9X = 279

X = 279/9

X = 31

.°. Therefore X = 31
