The mean of the numbers 3 5 7 is 5.
The arithmetic mean of a set of numbers is found by dividing the sum of all the numbers by how many numbers there are. In this case the arithmetic mean is: (8 + 7 + 7 + 5 + 3 + 2 + 2) / 7 ---> because there are 7 pieces of data. = 34 / 7 = 4.857 ( to 3 d.p.)
The numbers 3, 5, and 7 together have a range of 4 and a mean of 5.
6, 7 and 20.
The concept of a mean is simple. If you are looking at a series of 3 numbers, lets just say 2, 7, & 9, and you have to find the mean, here's how:Add up all of the numbers, (2+7+9=18)Divide by the number of numbers (In this case the number of numbers is 3, so you have to divide by 3. So 18 ÷ 3 = 6, so the mean is six.)
The mean of the numbers 3 5 7 is 5.
the mean of those numbers is 7
they are odd numbers
The arithmetic mean of a set of numbers is found by dividing the sum of all the numbers by how many numbers there are. In this case the arithmetic mean is: (8 + 7 + 7 + 5 + 3 + 2 + 2) / 7 ---> because there are 7 pieces of data. = 34 / 7 = 4.857 ( to 3 d.p.)
5 + 3 + 7 + 3 + 2 = 20/5 = 4 The mean of the numbers is 4.
The numbers 3, 5, and 7 together have a range of 4 and a mean of 5.

The mean of a set of data is the average. You find it by adding the numbers and dividing by the amount of numbers. For example 1, 2, 3, 4, 5, 6, 7 mean = 1+2+3+4+5+6+7 / 7 28/7 (28 is the sum of the numbers, 7 is the amount of numbers in the set) The mean is 4.
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
because in a mean for 7 with three numbers the total of the 3 numbers must be 21 and (even number) + (even number) = (even number) 21 is odd Q.E.D
Factors cannot be used to get means. The mean of 3, 7 and 13 is (3+7+13)/3 = 23/3 = 72/3 The numbers whose mean was calculated (3, 7 and 13) were all prime numbers, there were a prime number of them (3), and their sum was prime (23). No factors in sight!
add up all the numbers you have and then divide this result by how many numbers you have. example to find the mean of the following six numbers 6 7 9 3 3 2 first add up all the numbers = 6+7+9+3+3+2=30 then divide this result by how many numbers there are = 30 / 6 = 5 The mean is 5
