Add all the numbers in the list then divide it by how many numbers are in that list.       Ex. 5,8,1,4 Would be: 5+8+1+4= 18 divided by 4 which is 4.5

To find the mean of a data set, you need to take all the data in the set and add them together.

Example: Sarah scored these numbers on her midterms every quarter: 89, 97, 76, & 62. What is the mean of her test scores?

So, add all the scores together.

89 + 97 + 76 + 62 = 324

After adding the scores together, you need to divide the sum by the number of numbers in the data set.

324 ÷ 4 = 81

So, the mean, or average of her test scores is 81. 

I hope I helped :)

A guy walks into the store and steals $100 bill from the register without the owner’s knowledge. He comes back 5 minutes later a
Artemon [7]
The answer is $100
first the guy steals $100 from the owner. Therefore that $100 is a direct loss for the owner. 
the same guy comes and pays $100 for goods worth $70. and the balance is paid back to the guy. 
So the owner gets 100 and pays back 30 and gives goods worth 70. Therefore that transaction is cancelled as the amounts have been paid and no net effect with that transaction . the owner gets 70 for the goods he sold so that transaction wont lose his money. the fact that the guy paid for the bill with the money he stole isn't relevant here as the transaction has been completed
so the only loss for the owner is the $100 the guy stole at first 
answer is $100

44 × 20 × 10 = 440 × 2. but is it true or false ?
Vinil7 [7]
If you would like to know if 44 * 20 * 10 equals to 440 * 2, you can check it like this:

44 * 20 * 10 = 440 * 20 = 8800
and
440 * 2 = 880

So, the correct result is False, because 8800 is not equal to 880.

Answer:

The domain is all the possible inputs for this function. The range is all the possible outputs for this function.

The line starts at the <em>x-value</em> of 0 and ends at the <em>x-value</em> of 12. Therefore, your domain is D: [0, 12].

The line starts at the <em>y-value</em> of 9000 and ends at the <em>y-value</em> of 0. Therefore, your range is R: [0, 9000].
