Sun Yi needs pieces measuring 1/8 meter for a project. what is the greatest number of pieces measuring 1/8 meter that can be cut from the ribbon? how much ribbon will be left after Sun Yi cuts the ribbon? (Please help me :) thank you!!) Btw I'm not actually in college..Im using my mom's friend's daughter's account! I'm in middle school

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.
