The given graph is that of a function of the average cumulative monthly rainfall in Seattle. It does not represent the average cumulative daily rainfall. As per the graph, the average cumulative annual rainfall in Seattle is about 35 inches. The approximate average cumulative rainfall in Seattle in December is about 6.5 inches. The average rainfall, in Seattle, is greatest in December as the slope of the graph is greatest from November to December.
Note:
The scale on the Y-Axis shows changes of 5 inches in average cumulative rainfall. Therefore, the estimate for the approximate average cumulative rainfall in Seattle in December has been made by superimposing the graph on another graph paper with a suitable scale.
