At 9:00, Paula has x cups of food in a container for her dog. Paula pours a 2 1/2 cup box of food into the container. Then she removes 3/4 cup of food to feed her dog. Now there are 5 1/4 cups of food in the container. write an equation that can be used to determine the number of cups, x, of food in the container at 9:00?

Which equation can be used to determine the number of cups of food, x, in the container at 9:00?

A.5 1/4 = x + 212 + 34
B.5 1/4 = x − 212 + 34
C.5 1/4 = x + 212 − 34
D.5 1/4 = x − 212 −34

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.
