Niko had his savings increase by %5 this year. He started out with $350 in his account and calculated how much he had at the end of the year by using the following sets of calculations. $350 x 0.05 equals $17.50 $350 + $17 and $0.50 equals $367.50 find a single number that Nico could have multiplied his starting amount of $350 by.

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.
