What is the average of 5 10 15?
Average(5, 10, 15) = (5 + 10 + 15)/3 = 30/3 = 10
What is the average of 5 and 10?
5 + 10 = 15. To take the average, add all the units to be averaged, then divide that number by the number of units, in this case, 2. So, 15/2 = 7-1/2 or simply, 7.5.
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 10 10 10 10 15 15 and 0?
10 + 10 + 10 + 10 + 15 + 15 + 0 = 7070/7 = 10Average = 10
Which number is the next logical number in the following sequence of numbers 5 10 15 10?
5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15
What is the average of 12 15 23 10?
15
What is the average 12 15 23 10?
15
What is the average of 11 15 and 10?
Average = 12
What number increased by -10 is 5?
15. 5 - -10 = 5 + 10 = 15 → 15 + -10 = 15 - 10 = 5
What is the average of 10 and 15?
It is: 12.5
What number is next 5 10 15 10?
The Next NumberThe next number is 25 if you use the following pattern: 5, (the number 10), 15 (the first number +10), (the number 10), and the next number is the third number +10 or 25.or you could think of it this way:5, 10 (+5), 15 (+5), -5 (10)The pattern is +5, +5, -5, so the next number would be 15, the next 20, and the next 15.
What is a mean of 5 10 15?
It means you are counting in increments of 5. 5+5=10, 10+5=15. If by the word "mean", you are talking about the average, then the mean is 10. To determine the average of any group of numbers, add the numbers and divide the total by the number of numbers added - (does this makes sense?) Example: 5 + 10 + 15 = 30. Divide 30 by 3 (you added 3 numbers together to get the total) and the average is 10. Hope this helps.
