To calculate the mean of the dataset (5, 5, 5, 10, 15, 20, 30, 40, 100, 120), follow these steps:

  1. Sum all the values: \( 5 + 5 + 5 + 10 + 15 + 20 + 30 + 40 + 100 + 120 = 5 + 5 + 5 + 10 + 15 + 20 + 30 + 40 + 100 + 120 = 100 + 105 + 40 + 120 = 505\)

  2. Count the number of values: There are 10 values in the dataset.

  3. Calculate the mean: \( \text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}} = \frac{505}{10} = 50.5\)

  4. Round to the nearest whole number: The mean rounded to the nearest whole number is 51.

So, the mean of the dataset is 51.
