The spread of a dataset is typically calculated as the difference between the maximum value and the minimum value.
In the dataset 16, 40, 39, 45, 20:
- The maximum value is 45.
- The minimum value is 16.
So, the spread can be calculated as:
\[ \text{Spread} = \text{Maximum} - \text{Minimum} = 45 - 16 = 29 \]
Therefore, the correct equation that gives the value of the spread is:
45−16=29 45 minus 16 equals 29.
