(5 + 6 + 6 + 9) = 26/4 = 6.5. The mean of the four numbers is therefore 6.5.
If 6 numbers have a mean value of 9 then they must add to 54 (6*9) not 56. The question can not therefore be answered as the figures are incorrect.
To find the mean you add all of the numbers that are there and divide your answer by how many numbers there are. Example: Find the mean of 4, 5, and 9 . 4 + 5 + 9 = 18 18/3 = 6 6 is the mean of 4, 5, and 9.
No. Geometric mean of n numbers is the nth root of the product of the n numbers. → geometric mean of 4 and 9 is √(4×9) = √36 = 6.
The mean or average of THIS set of numbers is found by adding the 6 numbers and dividing by 6. 90/6 = 15.
The answer is 5.
5
The sum of these numbers is 38. There are 8 numbers. The mean is thus:38/8 = 4.75
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
The mean of those seven numbers is (5 + 9 + 6 + 6 + 11 + 8 + 4)/7 = 7 The median of those seven numbers is 6. The mode of those numbers - the only number which appears more than once - is 6.
To find the mean, you first add up all the numbers.20+10+13+20+9+6=78Then, you divide by how many numbers there are.78/6=13The answer is 13.
