Below is a graph that shows the number of visitors that visit a beach at various temperatures. b) d) Beach Visitors 600 525 450 375 300 225 150 75 0 Visitors 80 84 88 92 96 Average Daily Temperature (\"F) What is the independent variable? Justify your answer. What is the dependent variable? Justify your answer. What is the relationship between the variables ? Justify your answer. At what temperature are there the most people at the beach? How many visitors were there at the beach at that temperature? Question 2. Ricardo belongs to a bird-watching club. Every two days, he goes out and counts the number of birds he sees. The scatter plot shows the number of birds he saw in the past 12 days. Birds 0 2 4 6 81012141618 Days After doing some calculations. Ricardo found that the equation of the line of best fit is: y=0.5x+3 a) Based only on the graph does it seem reasonable that this could be the line of best t? Justify your answer. Note: Do not do any calculations here, you must only base your answer on the graph. b) Using Ricardo's equation, what is the amount of birds he saw on the 8th day? Is this interpolation or extrapolation? Show your work and Justify your answer: c) Using Ricardo's equation, how many birds is he expected to see on the 20th day? Is this interpolation or extrapolation? Show your work and Justify your answer: Question 3. Examine the scatter plot below and answer the questions that follow. a) What is the relationship between the variables ? Justify your answer. b) Find the equation of the line of best t using the points (30, 47.467) and (65, 25.067). Show your work and d_o n_ot round any of your answers
