Please help guys, I'm so stuck on this 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] 

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) 

Please someone help me!

anonymous · Answer

ok first keep the formula y=mx+b

secondly try plotting the thing

anonymous · Answer

I would plot it for you but os has the worst drawing tool i've seen on all the internet.

anonymous · Answer

I did graph it, and I believe the correlation coefficient is -.04 but I'm not sure what that means for the relationship between the time and velocity @timo86m

show me how the graph looks like.

A relation ship between time and velocity is acceleration.

anonymous · Answer

I know its acceleration, I'm just confused about what it means in this problem. @timo86m

anonymous · Answer

The graph doesn't seem to be going in any direction, does this mean it has no correlation or just a very low negative correlation? @timo86m

anonymous · Answer

0 correlation

Okay, I think I can do the rest. Thanks! @timo86m
