the mean is 13.7
min= 12 max=21 median=17 mode=17 mean=191
Add the 4 numbers together and divide by 4, the answer is 17.
17
Sum = 85 Number = 5 So mean = 85/5 = 17
Mean = 14 Median = 12 Mode = 12
mean = 19 median = 12 mode = 12
You can add any one of 13, 15, 17, 19 and 21.
12/17 ÷ 4/21 = 63/17 or 312/17
The number halfway between 13 and 21 can be found by taking the average of the two numbers. Add 13 and 21 together to get 34, then divide by 2 to get 17. Therefore, the number halfway between 13 and 21 is 17.
(Matthew 21:12-13)(Mark 11:15-17)(John 2:13-17)
16.5 is the median.
13 + 21 - 7 + 12 = 15
