In a class, 45 students take the sat exam. the number of boys is 7 more than the number of girls

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

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.
