:a telephone company offers monthly cellular phone plans for $15. it includes 200 anytime minutes but has a charge of $0.25 per minute beyond 200 minutes. i really need finding a piecewise function for this. i already wrote: c(x) = {15 if 0 ≤ x ≤ 200; .25(x-200) + 15 if x > 200} i don't understand why the second part is wrong because to do 15+.25x would charge the customer for all of the minutes and leave out the 200 free ones? ?

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.
