5+7+9+12+12 = 45 and 45/5 = 9 which is the mean average

the average of 7,9,11,12,16 is = (7+9+11+12+16)/5 =11

The average is 10... 11+11+9+7+12=50... 50/5=10

Average = (8 + 9 + 5 + 6)/4 = 7 Average = (8 + 9 + 5 + 6)/4 = 7 Average = (8 + 9 + 5 + 6)/4 = 7 Average = (8 + 9 + 5 + 6)/4 = 7

The mean of those data points is 9.

=12*(9+5)/7 = 12*14/7 = 12*2 = 24

5 + 9 + 7 = 21/3 = 7 Therefore, the average of the three numbers is 7.

A Possible Answer could be: 70 9 12 12 10 5 1

The mean is 7, the median is 7 and the modes are 5, 7 and 9.

Average = (12 + 8 + 7)/3 = 27/3 = 9

5-7 liters 9-12 pints The adult has 7 litres of blood.

The "N"th term is -7. You can deduce this from: 19 - 7 = 12 - 7 = 5 - 7 = -2 - 7 = -9

The ratio of 5 and 7 8 and 9 12 and 18 85 and 170 is 5:7/8:9/12:18/85:170.

Sample size: 12 Sorted sample: 3, 5, 6, 6, 7, 7, 8, 9, 9, 9, 10, 10 Middle numbers: 7, 8 Average of middle numbers, known as median: 7.5

If that's 5/12, 10/13 and 7/9, the LCD is 468.
