If the mean of 6 10 12 x 16 18 is 15 find the value of x​
Mumz [18]

Answer:

x=28

Step-by-step explanation:

I am assuming the mean is arithmetic mean. So we first add up the numbers:

6+10+12+18+16+x

=22+10+30+x

=22+40+x

=62+x

Then since there's 6 numbers in total, we have an equation:

\frac{62+x}{6}=15\\62+x=90\\x=28

The answer is 28!

Have a nice day! :)
