How to Calculate Midpoint?
The x-coordinate of the midpoint M of the segment
is the arithmetic mean of the x-coordinates of the endpoints of the segment
. Similarly, the y-coordinate of the midpoint M of the segment
is the arithmetic mean of the y-coordinates of the endpoints of the segment
.
Step-by-step explanation:
Notice that B = {1, 3, 5, 7} and C = {0, 2, 4, 6, 8, 10}.
A U B = {1, 3, 5, 7}.
B ∩ C = { }.
A U C = {0, 1, 2, 4, 5, 6, 7, 8, 10}.
