A group of students was given a bag with 100 marbles inside; some marbles were red and some were blue. The students were not allowed to look in the bag, so they each conducted experiments with 20 trials to try to determine the composition of the marbles in the bag. · Ms. Johnson picked a red marble 4 times · Ms. Masco picked a red marble 5 times · Ms. Armstrong picked a red marble 6 times Of the 100 marbles in the bag, how many are likely to be red?

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)
