How do you find the average in a list of numbers?

First, you add them all up. Then you divide what you've got by how much numbers you've got in the list.


What number goes into 130?

Oh, what a happy little question! Let's think about this together. To find a number that goes into 130, we can start by looking at factors like 1, 2, 5, 10, 13, 26, 65, and 130. Each of these numbers can be multiplied by another number to equal 130, like puzzle pieces fitting together on a canvas. Just explore and see which one feels right for you!


What 4 numbers have a mean of 80?

to find mean of four numbers, you would take the four numbers and add them. Then you would divide them by four. Now, if you want a mean of 80, just reverse the process. take the mean you want and multiply by four. Then just find four numbers that add up to the number you just got. For example if you wanted 3 numbers that have a mean of 110, you would take 110 and multiply it by 3 to get 330. Then you would find three numbers that add to 330 to get your answer. So the answer to my sample could be the numbers 1, 1, and 328 because they add to 330. A possible answer to your question would be 1, 1, 1, and 317 because if you add them up and divide by four, you would have 317+1+1+1=320. Then 320/4=80. So a possible answer could be 317, 1, 1, and 1.

How do you work out the mean of a set of numbers?

First you have to add the set of numbers that you have: 3 + 5 + 6 + 2 = 16 Second, with the answer that you got from adding, (16) divide that number with the amount of numbers given. ex: 3,5,6,2 - there are 4 numbers. 16 ÷ 4 = 4 Then the answer that you got from dividing, is your mean.

What five adjacent even numbers add up to 930?

Oh, dude, that's like asking me to do math on a Friday night. But hey, I got you. So, let's break it down - if you have five even numbers next to each other, the middle number would be the average. If they add up to 930, then the middle number (which is the third number in this case) would be 186. So, the five numbers would be 182, 184, 186, 188, and 190. Math is cool, but like, not my thing, you know?
