I really need some help.....plzzzz... fan and medal....anyone!!
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. [Choose the value of correlation coefficient from −1, 1, −0.04, 0.99]
* i got -0.04
since the correlation coefficient is negative it almost has no correlation, therefore there is no relation between the velocity and time. *
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?
*i got :
slope between 10 and 20 = 0.06
-> the slope indicates that the velocity is increasing at a relatively slow rate from 10 to 20 minutes*
Part C: Does the data in the table represent correlation or causation? Explain your answer.
i need help with part c

the data in the the table represents correlation beacause in part A it mentions correlation but it does not mention causation so therefore the data in the table represents correlation.
i will be waiting for my medal and for u to become my fan like u said.
