Question

Find the correlation coefficient, r, of the data described below. The manager of a ski resort in the Alps always worries there won’t be enough snow to keep the resort open into the spring. She decided to see if there was a relationship between the temperature in January and the amount of snow in the spring. For several years, she recorded the average temperature in January (in Celsius), x. On March 1, she also measured the depth of the snow at the bottom of a particular ski slope (in centimeters), y. Average temperature (in Celsius) Snow depth (in centimeters) −6.68 53.08 −1.01 57.31 1.06 45.92 3.53 32.80 4.31 32.91 Round your answer to the nearest thousandth

Question

For each system of equations, drag the true statement about its solution set to the box under the system. One Solution: The graphs of these lines would intersect at a point. Infinitely Many Solutions: 2x + 5 is a multiple of x + 5. Zero Solutions: y is equal to two different expressions. Zero Solutions: 2x + 5 = x + 5 has no solutions. Infinitely Many Solutions: Both the right and left sides of the equations are equivalent expressions
