Answer:
=16
___________________
Step-by-step explanation:
[tex]\frac{a+b+c+d+e}{5} = 10[/tex]
then ,
a+b+c+d+e = 50
Now, if we add a new number and call it f we will get:
[tex]\frac{a+b+c+d+e+f}{6} =11[/tex]
then,
(a+b+c+d+e) + f = 66
then f=66-(a+b+c+d+e) = 66-50=16.
:)
mean of 5 numbers = 10
mean of 6 numbers = 11
therefore, mean= 7 + 13 + 6 + 14 + 10 = 50 = 10
5 5
if one more number make it 11, then
2x=10
2 2
x=5
