Which correctly explains how to estimate 33 percent of 87? Round 33 percent to 20 percent and 87 to 80. Think of 20 percent as 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 30 percent of 80 is 8 + 8, which is 16.
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 35 percent and 87 to 90. Think of 35 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 35 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 40 percent and 87 to 80. Think of 40 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 40 percent of 90 is 8 + 8 + 8, which is 24.

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.
