Agroup of roommates decide to split the cost of their groceries. if g is the amount spent on groceries and n is the number of roommates, the formula determines each person’s share of the cost. if each person’s share was $104.50 and 6 roommates live in the house, what was the cost of the groceries? a. $627.00 b. $604.50 c. $574.16 d. $174.17

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.
