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
A number is chosen at random from the first 10 whole number What is the probability that it is not exactly divisible by 3?
the first 10 whole numbers are numbers 1 to 10 and in those numbers only 3 numbers are divisible by 3 in which 3, 6 and 9 therefore the probability of from those figures that the numbers won't be divisible by 3 is 7/10 or 70%.
What 3 numbers have a mean of 30?
10
What does mean mean?
Well mean means being mean and the other mean (eg. i mean that)The mean of a group of numbers is also known as the average. It is the sum of the numbers divided by the number of terms.For example, the mean (average) of 3, 5, and 10 is (3 + 5 + 10) / 3, which gives 6.
Mean of a set of numbers?
The mean is a form of average. Generally speaking, the mean of a set of numbers is the result of adding all the numbers together and dividing by the number of numbers e.g. 1, 3, 5, 6, 6, 10, 11 The mean is 1 + 3 + 5 + 6 + 6 + 10 + 11 7 = 6
What does the word mean mean in mathmatical terms?
it means the average. add up all of the numbers and divide by the number of numbers you added. for example, 10+ 10+10=30 the mean is 30 divided by 3 = 10 the average! A nasty average?
How do uu find the mean?
To find the mean you first have to add up all the numbers then you divide it by how many numbers you have and you got the mean. Example: 12+13+5=30 30/3=10 10 is the mean
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.
What numbers divide evenly into 90?
If you mean whole numbers, then they are: 1, 2, 3, 5, 9, 10
