|Diameter (In.)||Age (years)|
3. Tree Diameter and Age To estimate ages of trees, forest rangers use a linear model that relates tree diameter to age. The model is useful because tree diameter is much easier to measure than tree age (which requires special tools for extracting a representative cross section of the tree and counting the rings). To find the model, use the data in the table, which were collected for a certain variety of oaks.
(C) Use the model to estimate the age of an oak whose diameter is 18 in.
To graph: The scatter plot of the data.
Consider the Diameter of the tree as the x coordinates and age of the tree as the y coordinates.
The scatter plots of the given data are shown below in Figure 1...
To find: The linear function that represents the given data and draws the graph for the same.
To find: The age of an oak if the diameter is 18 in.
