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 About the author Margaret
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 7×8=56 That means 6+9+4+2+6+15+x=56 42+x=56 Therefore x=14 Reply
Answer: ( 6 + 9 + 4 + 2 + 6 + 15 + x ) / 7 = 8 ( 42 + x) /7 = 8 x = (8 x 7) -42 x = 56 – 42 x = 14 Reply
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 7×8=56
That means 6+9+4+2+6+15+x=56
42+x=56
Therefore x=14
Answer:
( 6 + 9 + 4 + 2 + 6 + 15 + x ) / 7 = 8
( 42 + x) /7 = 8
x = (8 x 7) -42
x = 56 – 42
x = 14
