The coordinates of the midpoint of a line segment joining two points (x₁,y₁) and (x₂, y₂) is given by
[(x₁+x₂)/2, (y₁+y₂)/2].

Given:
(x₁,y₁) = (3,6)  for the point U.

For the midpoint,
(x₁+x₂)/2 = 5   or x₁ + x₂ = 10
(y₁+y₂)/2 = -10 or  y₁ + y₂ = -20

Therefore, the coordinates of V are
3 + x₂ = 10     =>  x₂ = 7
6 + y₂ = -20  =>   y₂ = -26

Answer:  V (7, -26)

Answer:

The z-distribution should be used for this problem.

Step-by-step explanation:

The population distribution is assumed to be normal. Which distribution to use?

If we have the standard deviation for the sample, we use the t-distribution.

If we use the standard deviation for the population, we use the z-distribution.

There is a known standard deviation of 2.2 minutes.

This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.
