Apainter made the table below to show the amount of paint it takes to cover a certain amount of square feet. the amount of paint varies directly with the area of each wall. amount of paint and size of wall area of wall mc017-1.jpg, x 64 144 400 amount of paint (pints), y 4 9 25 how much paint should the painter expect to use to paint a wall with an area of 256 square feet? 16 pints 32 pints 128 pints 225 pints

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.
