Question

1. the line graph shows the average rainfall, in inches, for a city. the horizontal axis represents january through june, the first six months of the year. the vertical axis represents the number of inches. find the range of the data.

Explanation:

Step1: Recall the formula for range

The range of a data - set is calculated as \(Range = \text{Maximum value}-\text{Minimum value}\).

Step2: Identify the maximum and minimum values

From the line - graph, the values are \(2.91\), \(2.6\), \(3.86\), \(3.19\), \(3.49\), \(3.27\).
The maximum value \(M = 3.86\) and the minimum value \(m=2.6\).

Step3: Calculate the range

Substitute the values into the formula: \(Range=3.86 - 2.6\).
