The correlation coefficient that models the relationship between the amount of time Jason spends working out and the amount of weight he loses is −0.9547. What is the correct interpretation of this number?
A) The correlation coefficient is close to 0. There is a weak positive correlation between the amount of time spent working out and the amount of weight lost.
B) The correlation coefficient is close to -1. There is a weak negative correlation between the amount of time spent working out and the amount of weight lost.
C) The correlation coefficient is close to -1. The correlation between the amount of time spent working out and the amount of weight lost cannot be determined.
D) The correlation coefficient is close to -1. There is a strong negative correlation between the amount of time spent working out and the amount of weight lost.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
