Question

The table below shows the velocity y, in miles per minute, of a toy car at different times x, in minutes:

Time (x)
(minutes)
10 20 30 40


Velocity (y)
(miles)
0.2 0.8 0.1 0.4
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 velocity of the toy car. (4 points)
[Choose the value of correlation coefficient from −1, 1, −0.04, 0.99]

Answer 1

Part B: What is the value of the slope of the graph of velocity versus time between 10 minutes and 20 minutes, 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)

@campbell_st

Answer 3

so have you plotted the points..?

Answer 4

you need to do this to be about to make a comment about the correlation or the connection between time and velocity

Answer 5

I don't understand, can you help me out @campbell_st

Answer 6

Answer 7

@aric200

Answer 8

You need to plot like campbell said

Answer 9

There are x and Y values

Answer 10

so, if I plot them, it will give me all the answers to the questions?

Answer 11

Here I must go Review this previously asked question
