1. Determine if the following graph is a tree?
2. As few trails as possible are to be built between houses in a primitive community
so that it is possible for a resident to go from any house to any other. If there are
34 houses, how many trails need to be built? Since it is considered bad luck to
live at the end of a trail, can the trails be constructed so that no house is so
situated?
3. Need the following graph in editable format, i.e. xls, doc, etc. Need to somehow
create a graph identical to one below, however I need it to be done in a format I
can edit (the picture I cannot edit). Thx
