Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

Answer:
32 kilowatt-hours.
Step-by-step explanation:
The energy usages per day (in kilowatt-hours) of houses on Hamlet Avenue are listed below:
30, 23, 38, 36, 33.
Therefore, the mean energy usage per day of the houses of Hamlet Avenue will be
= 
= 32 kilowatt-hours.
The mean of n numbers is given by,
. (Answer)
Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)
A 180 degree rotation around the origin flips the signs of x and y, so you get:
(2, 8) (6, 8) (11, 1) (7, 3)
Then a translation to the left 6 units just subtracts 6 from all the x values:
(-4, 8) (0, 8) (5, 1) (1, 3)
Those are your points! Hope this helped!
