Find the mean of the following ungrouped data:
1, 2, 5, 7, 9, 10 = 35r - 4
Answer (2)
To find the mean of the numbers 1, 2, 5, 7, 9, and 10, you add them together to get a total of 34. Then, divide this total by the number of values, which is 6. The mean is approximately 5.67.

To find the mean of a set of ungrouped data, you need to follow these steps:
Add all the numbers together : This gives you the sum of the dataset. In this case, the numbers are 1, 2, 5, 7, 9, and 10.
Sum = 1 + 2 + 5 + 7 + 9 + 10 = 34
Count how many numbers are in the dataset : There are six numbers here.
Divide the sum by the number of elements in the dataset : This will give you the mean.
Mean = Number of numbers Sum of numbers = 6 34 = 5.67
Therefore, the mean of the numbers 1, 2, 5, 7, 9, and 10 is approximately 5.67.
The expression '35r - 4' seems to be unrelated to the task of finding the mean from the given numbers, so it was not included in the calculations.
