How do you find the arithmetic mean of the first one thousand positive odd numbers?
The sum of all odd numbers, up to the odd number (2n-1) is n^2. So the sum of the first 1000 or 10^3 odd positive numbers is (10^3)^2=10^6 Now divide by 10^3 or 1000 since we have 1000 numbers so we have 10^6/10^3=1000 The mean of the first 1000 positive odd numbers is 1000 If you ask the mean of the odd numbers between, 1 and 1000, that is another problem, since there are 500 of them, the answer would be 500^2/500=500 Think of the mean of the odd numbers between 1 and 10, there are 5 of them and there sum is 25 so the mean is 25/5 or 5 **** in general, the arithmetic mean of the first n odd numbers is n^2/n or n. So that is why the number is 1000.
What is the mean of 15 10 15?
Mean is calculated by adding the numbers, then divide by the count of numbers.The count is 3 in this case. 15 + 10 + 15 = 40, so mean = 40/3 = 13.3333.....
What is the ratio of even numbers to square numbers in the set of whole numbers from 1 to 20?
10:4
What is the mean of 15 10 5?
The mean is the sum of the three numbers divided by 3.So in this case the sum is 30 and 30 divided by 3 is 10.10 is the mean and the median too
What is the mean average of 6 8 and 10?
Well, isn't that a happy little question! To find the mean average of 6, 8, and 10, you simply add them all together and then divide by how many numbers there are. So, 6 + 8 + 10 equals 24, and when you divide 24 by 3 (since there are 3 numbers), you get a mean average of 8. Just like that, you've found the gentle average of these numbers!
