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.

If you look closely the area where 3x is congruent to the other side of the 90 degree angle with one part as 0.5x + 34

So
3x + 0.5x + 34= 90

x will be 16

So plug it in

0.5(16) + 34= 42 degrees

And

3(16)= 48 degrees

That left half of the circle is 180 degrees and since we know the angle 3x is 48 degrees we subtract it from 180 to get angle AE

180-48

132 degrees is your answer
