It is: 13+9+11 = 33 and 33/3 = 11 which is the mean average
Average: (13+9)/2 = 11
Average = (9+13)/2 = 22/2 = 11
The average is 13.
The average of 9, 15, 11, and 13 is 12. It is calculated by adding all the numbers together (9+15+11+13 = 48) and then dividing by the total number of values (4).
7 + 9 + 11 = 27. Divide by 3. = 9.
The number halfway between 9 and 13 can be found by calculating the average of the two numbers. To do this, you add 9 and 13 together to get 22, and then divide by 2 to find the average, which is 11. Therefore, the number halfway between 9 and 13 is 11.
The average is (11+11+13+17)/4 = 52/4 = 13
Add them together and divide by 6.
13 + 9 + 2 + 11 + 18 + 13 = 66/6 = 11
median of {5, 15, 9, 13} is 11 To find the median of a dataset sort the data into order and the median is the middle one; if there are an even number of items in the dataset, then the median is the mean average of the middle two. {5, 15, 9, 13} → {5, 9, 13, 15} There are 4 data items, → median is mean of {9, 13} = (9 + 13) / 2 = 11.
There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.
It is 11 by adding them together and then dividing them by 6
