Question

If the mean of five observation x, x+2, x+4, x+6 and x+8 is 11 , then the value of x is​

Answer 1

Answer:

mean = sum of observations÷total no. of observations

11=x+x+2+x+4+x+6+x+8/5

hence,

x=9

Answer 2

Answer:

7

Step-by-step explanation:

x, x+2, x+4, x+6 and x+8 is 11

x+ x+2+ x+4+ x+6 + x+8= 11 x5

5x +20 = 55

x + 4 = 11

x = 7
