Question

If the mean of the data 6, 9, 4, 2, 6, 15 is 8, then what is the value of x?
(A) 7
(B) 8
(C) 12
(D) 13​

Answer 1

Answer:

14 Either the question is wrong or the given options are wrong

Step-by-step explanation:

I think you missed to mention the x in question

I'm considering the numbers as follows

6,9,4,2,6,15,x

Mean of the 7 numbers is 8

Therefore sum of 7 numbers is 7x8=56

That means 6+9+4+2+6+15+x=56

42+x=56

Therefore x=14

Answer 2

Answer:

( 6 + 9 + 4 + 2 + 6 + 15 + x ) / 7 = 8

( 42 + x) /7 = 8

x = (8 x 7) -42

x = 56 - 42

x = 14
