6 is the average of 7,6,2, and 9 because 7+6+2+9=24, 24 divided by 4 is 6!
It is: 8+7+7+5+3+2+2 = 34/7 => 4 and 6/7 which is the average mean
5.8
5 2/5
6 is the average of 7,6,2, and 9 because 7+6+2+9=24, 24 divided by 4 is 6!
6
3+7+2+8+10 = 30 30 ÷ 5 = 6 Average = 6
5
7
(6 + 8) ÷ 2 = 7
6+8+7= 21 21/3 = 7 The average is 7.
The average mean is 4 and 1/7
8+9+6 = 23 23/3 = 7 and 2/3
An 'average' in math is a form of central tendency. An average best describes what a group of numbers or letters' median is. Ex: A set of numbers - 2, 14, 6 , 4, 35, 7 First: You have to put the numbers from least to greatest. Ex: 2, 4, 6, 7, 14, 35 Then you count of from beginning and end towards the middle number which is between 6 and 7. In these cases you add the two numbers together and divide by the number of numbers which is 2. (6+7)/2 13/2 6.5 is your average in the set of numbers.
The answer is 6 / (1-5/7). 1- 5/7 = 2/7 6 / (2/7) = 6 * (7/2) = (6*7)/2 = 42/2 = 21. Simples!
the sum of -2 and 6 and 7 is (-2+6+7)
