Let A, B, C be three collinear points and let D, E, F be the midpoints of segments AB, BC, and AC, respectively. Prove that the segments DE and BF have the same midpoint. Let d be a line and let A, B, C be three points not on d. Prove that if d does not separate points A and B and it does not separate points B and C, then it does not separate points A and C.

3. a) Three neighbors need to locate their mailboxes so that the mail carrier will only need to make one stop each day for all three of them. They decide to choose a spot for the mailboxes so that each neighbor is required to walk the same distance from his/her home to the mailbox.

Let A-B-C denote B is between A and C. For this problem, use the following three axioms: A1: Each pair of points is assigned a number, called the distance between A and B. it is denoted by AB. A2: Given any points A and B, then AB 20. Equality holds precisely when A=B. A3: For all points A and B, ABEBA Suppose A, B, C, and D are collinear. Assume that A-B-C means: A, B, and C are distinct, collinear...

A bus travels between two cities A and B which are 100 miles apart. If the bus has a breakdown, the distance from the breakdown to city A has a uniform distribution over (0,100). There is a bus service station located 40 miles from A (between A and B) Find the expected distance from the breakdown location to the service station.
