Ervin practices hitting golf balls at the driving range. He hits the balls toward a far-away putting green. The scatter plot below shows the wind speed when Ervin strikes each golf ball and how close to the putting green each shot lands. A line of best fit for these data points, with equation y=1/3x+3 , is also shown on the plot. Ervin hits a golf ball when the wind gusts to 18 miles per hour. About how many yards from the putting green do the data suggest the ball will land?

A. 6

B. 9

C. 21

D. 45

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.
