Answer:

16

Step-by-step explanation:

The mean (average) of 4 numbers is 10 => the sum of these numbers are 10 x 4 = 40

x = 40 - 4 - 8 - 12 = 16

Hope it helps :)

Hello There today we will find the mean of those numbers

since our list is - [tex]4,8,x,12[/tex] and the mean is 10 we can make an equation

[tex]\frac{(4+8+x+12)}{4}=10\\(4+8+x+12)=40\\x=40-24\\x=16[/tex]

the mean is 16
