Jack drives 24 miles in 30 min. jill drives 52 miles in 60 min. are these equivalents rates? why?

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.

The range of the following relation r {(3, -5), (1, 2), (-1, -4), (-1, 2)} is (1 point){-4, -5, 2, 2){-1, 1, 3){-1,-1,1,3){-5, -4,2)

Three lines meet at a point. set up and solve an equation to find the value of (a) is your answer reasonable? explain how you know
