IDENTIFYING PROPERTIES Identify the property being illustrated. 26. -3 + 3 = 0

27. (-6 + 1) + 7 = -6+ (1+7)

28. 9 + (-1) = -1 + 9

29. -8+0= -8

30. (x + 2) + 3 = X + (2+3)

31. y + (-4) = -4 + y

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)

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if

Cone a has a surface area of 384 ft2 and cone b has a surface area of 96 ft? . what is the ratio of their volume?
