The table below shows the surface area y, in square feet, of a shrinking lake in x days: time (x) (days) 10 20 30 40 surface area (y) (square feet) 100 90 80 70 part a: what is the most likely value of the correlation coefficient of the data in the table? based on the correlation coefficient, describe the relationship between time and surface area of the lake. [choose the value of the correlation coefficient from −1, −0.99, −0.5, −0.02.] (4 points) part b: what is the value of the slope of the graph of surface area versus time between 20 and 30 days, and what does the slope represent? (3 points) part c: does the data in the table represent correlation or causation? explain your answer. (3 points)
