A. If you plot the points in a graph, it would look like that shown in the picture attached. If we use linear regression, the correlation is very poor. The coefficient of correlation (r2) is only 0.0017. There is no linear relationship between time and velocity.
B. The slope of the graph is equal to y2-y1/x2-x1, In this case, it would specifically be v2-v1/t2-t1
Slope = 0.8-0.2/20-10 = 0.06 miles/s^2
The slope represents the acceleration at time 10 to 20 minutes.
C. The table in the graph shows causation rather than correlation. The points in the data occur in a sequential manner.
We have point

, so first calculate

. There will be:

Now, we can write the equation of the normal line as:

Normal line (and every line) crosses x-axis when y = 0, so coordinates of A:
Answer:
Jane has 6 points, and B has 8 points.
Step-by-step explanation:
If both of them in total have 14 points, and B has 2 more points than Jane, this means that:
B+2=14
So to find their individual number of points, you need to take 2 away from 14
14-2=12
Since these are being divided to two people, you have to divide 12 too
12/2 = 6
6 is Jane's number of points. And now to find B just add 2 points to it which is 8.
Jane=6 Bondani=8
6+8=14
