Answer:
15 minutes more, as 60-45mins = 15 minutes.
Step-by-step explanation:
Distance = 30 miles
Speed = 30mph = 1 hr
Compared to Distance 30 miles
Speed = 40mph = 3/4 of 60mins = 45 mins.
1hr = 60mins = 60-45 = 15 minutes.
Answer:
The co variance of the midterm and final exam scores is 58.76.
Step-by-step explanation:
The formula to compute the sample co variance is:

The values are computed in the table below.
Compute the co variance as follows:

Thus, the co variance of the midterm and final exam scores is 58.76.
The triangle defined by three points on the coordinate plane is congruent with the triangle illustrated:
C) (4,2); (8,2); (4,8) because the corresponding pairs of sides and corresponding pairs of angles are congruent.
If we plot these points we can observe that they are congruent, we should also solve for the distance of each point between each other to conclude their congruency.
