Best ResponseYou've already chosen the best response.0The table below shows the distance y, in miles, traveled by a toy car in x minutes: Time (x) (minutes) 20 30 40 50 Distance (y) (miles) 5 10 15 20 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 distance traveled by the toy car. (4 points) [Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02] Part B: What is the value of the slope of the graph of distance versus time, 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)

Best ResponseYou've already chosen the best response.0okay slope is given by change in y/change in x so slope=5/10=1/2=0.5

Best ResponseYou've already chosen the best response.0Okay, so was that a different way of asking for slope?

Best ResponseYou've already chosen the best response.0this is part B part A u have to use correlation coefficeint formula

Best ResponseYou've already chosen the best response.0Oh! Okay, now I'm catching up. That confused me for a moment there.

Best ResponseYou've already chosen the best response.0depending on how high the correlation coefficent is it tells you how dependant the the values of y are on x, or vice vera

Best ResponseYou've already chosen the best response.0fill out those values and plug into formula, i can tell you right now, that the correlation is most likely +1 as it can be modeled perfectly as a slope intercept formula

Best ResponseYou've already chosen the best response.0It just doesn't make any sense to me, do you think you could walk me through it?
