(18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)/9= 12========The mean, also often called the "average", is1/9 of (18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)
Use the definition of average, write the corresponding equation, and solve it. In this case, the equation is:(3 + x + 16 + 18) / 4 = 11 since there are four numbers.
Mean = 11 Median = 11 Mode = 4 Range = 18
7, 11, (16), 18, 23. The median is 16 (shown in brackets).
The GCF is 1.
11 12 15 16 18 17 the answer is 15.5
Add the numbers together, and then - since there are three numbers - divide the result by 3.
