How do you use number line to calculate the average of two different averages?
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.

What is the average of 3 6 9 2?
5. 3+6+9+2 = 20 20 / 4 = 5. To calculate the average of a series of numbers you have to add them together and divide them by the amount of numbers given.
What is the average of 11 and 9?
11+9=20 20/2=10 average:10
What is the average of 9 and 31?
Average = (9 + 31)/2 = 40/2 = 20
What is the average of 20 22 18?
Average = sum(X)/n = 60/3 = 20
What is the LCM of 3 9 and 20?
The LCM is 180.
What is thrice the difference of 20 and 11?

9 over 20. 9/20
What is the least common denominator of 3 over 20 and 9 over 4?
The LCD for 3/20 and 9/4 is 20
What is the sum of 8 9 3?
20 = 3 + 8 + 9
What is 3 to the second power plus 5x4-9?
3 to the 2nd power plus 5 x 4 - 9 = 20 32 + 5 x 4 - 9= 9 + 20 - 9= 20
-3 plus 9 - 20 equals?
-3 + 9= 6. 6 - 20=-14. Therefore the answer is -14.
