10, just add them all together and divide by how many numbers there are. sometimes you will need a calculator but this time is a definite no
(12 + 18 + 0) / 3 = 30/3 = 10
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
The average = (18 + 12 + 13 + 17) ÷ 4 = 60 ÷ 4 = 15

median = 11.5 mean = 12
if ((18-18)/(12-14))**0.5 = 0 if (18-(18/12)-14)**0.5 = 1.58113883 if (18-18/(12-14))**0.5 = 3 if ((18-18)/12-14)**0.5 = 0
6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6
The average is 15.
The average is 18.
18 + 12 + 0 - 4 - 10 = 16
1O is the answer
The average = (18 + 12 + 13 + 17) ÷ 4 = 60 ÷ 4 = 15
Range = Maximum - minimum = 18 - 0 = 18
The average is 15.
(12+14+16+18)/4 = 15
6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.
6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.
