A12-sided number cube with the numbers 1 through 12 is rolled. select from the drop-down menu to correctly complete the statement. rounded to the nearest hundredth, the probability that the number cube lands on a number less than 5 is a. 0.33 b. 0.42 c. 0.58 d. 0.67

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.
