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]

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?

Part C: Does the data in the table represent correlation or causation? Explain your answer.

I need help ASAP so if anyone can help me I'd really appreciate it!
I'll give brainliest to whoever gives the best answer

Respuesta :

a] The most likely value of the correlation function for the data is -0.04, this i because the relationship between the two variables time and velocity do not how a strong linear relationship between them.

Part B:
The value of the slope between times 10 min and 20 min will be:
slope, m=(y-y1)/(x-x1)
thus taking points (10,0.2) and (20,0.8)
slope,m=(0.8-0.2)/(20-10)=0.6/10=0.06 miles/ min²

c] The relationship will be described as causation/ causality because time is partly responsible for the velocity of the toy and velocity is partly dependent on time.
