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.

Set of odds numbers divisible by 5 between 10 and 20?

set of odd numbers divisible by 2 between 10 and 20


What is halfway between negative 10 and positive 20?

5 It is 15 more than -10 and 15 less than +20. To find the halfway point (the average), add the two numbers and divide by 2. -10 + 20 = 10 divided by 2 = 5


What five numbers have a mean of 15 and a range of 10?

10, 20, 15, 17, 13


What is the average of 16 and 29 and 15?

To find the average or mean - Add all the numbers together and divide by the amount of numbers you added: So 16 + 29 + 15 = 60 (1) (2) (3) <- So 3 numbers added together 60 / 3 = 20. So the average of 16, 29, and 15 is 20.
