Suppose a plane is flying at an altitude of 32,200 feet two minutes after the start of its descent. Ten minutes after the start of its descent, the plane is at an altitude of 16,200 feet. Use the given information to construct a linear function that represents the altitude of the plane at any given time during its descent. What is the altitude of the plane at 12 minutes?

Write a mathematical argument that can be used to defend your solution.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
