Question

is the mean of 2 4 6 8 2 4 3 x 6 and 9 is 5 find the value of x

​

Answer 1

Mean=sum of all numbers/total number of all numbers

Here the mean is given as 5

And according to the question

Mean of (2+4+6+8+X+y ) is 5

Writing it in above form

(2+4+6+8+x+y)/6=5

Which is (20+X+y)/6 =5

On cross multiplication we get,

20+X+y=30

On rearranging we get,

X+y=30–20,

Which then implies

X+y=10

Done, HOPE IT HELPS

Answer 2

Answer:

value of x is 6

Step-by-step explanation:

2+4+6+8+2+4+3+x+6+9/10=5

44+x/10=5

44+x=5*10

44+x=50

x=50-44

x=6
