3.03b: Making Predictions from Linear Models

A farmer uses the equation y = -.15x to determine how many acres of crops (y) can be produced at various temperatures (x). Is the correlation of the data positive or negative?

A farmer uses the equation y = -.15x to determine how many acres of crops (y) can be produced at various temperatures (x). Use the linear model to predict the temperature at which 75 crops can be produced.

The table below displays the average number of pounds of milk and milk fat produced per cow in seven states in 2001.

In North Carolina in 2001, the production of milk per cow was 17,200 pounds. According to the line of best fit for the data above, approximately how many pounds of milk fat were produced per cow in NC?

In 2000 Jim planted a tree that was 4 ½ feet tall. In 2005 the tree was 15 ¾ feet tall. Assuming the growth of the tree is linear, what was the rate of growth of the tree? How tall should the tree be in 2010?
