write the arthametic means of 9,4,3,x,10,5,6 and 4 is 6. Find the value of x.​

1 thought on “write the arthametic means of 9,4,3,x,10,5,6 and 4 is 6. Find the value of x.​”

1. Step-by-step explanation:

   Given:–

   The arthametic means of 9,4,3,x,10,5,6 and 4 is 6.

   To find:–

   Find the value of x.

   Solution:–

   Given observations are 9,4,3,x,10,5,6 and 4

   Sum of all observations =

   9+4+3+x+10+5+6+4

   =41+x

   Number of all observations = 8

   Mean = 6

   We know that

   Mean = Sum of all observations/Number of all observations

   =>(41+x)/8 = 6

   =>41+x = 6×8

   =>41+x = 48

   =>x = 48-41

   =>x = 7

   Answer:–

   The value of x for the given problem is 7

   Check:–

   The observations are 9,4,3,7,10,5,6 and 4

   Mean = Sum of all observations/Number of all observations

   =>Mean = (9+4+3+7+10+5+6+4)/8

   =>Mean = 48/8

   Mean = 6

   Verified the given relations

   Used formulae:–

   • Mean = Sum of all observations/Number of all observations
