The left vertical plane intersects the horizontal plane at line x. The right vertical plane intersects the horizontal plane at line w. Line y intersects line x at point B and intersects line w at point A. Line v extends vertically through the horizontal plane. Line z extends horizontally through the left vertical plane. Point C is on the lower half of the left plane is on line z. Point D is on line z but not on the left vertical plane. Point E is on the lower half of the right plane. Use the given diagram to answer the question. Which line is the intersection of two of the planes shown?

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
