Sense-Making. Ray-Ray is building a deck in his back yard. The plans for the deck show that it is to be 30 feet by 30 feet. Ray-Ray realizes that he does not have that much space in the back yard, so he has to reduce the dimensions. He wants to reduce one dimension by a number of feet and increase the other dimension by the same number of feet. If the area of the reduced deck is 275 square feet, what are the dimensions of the deck?​

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.
