For an LP model with m equality constraints and n decision variables, if n>m, which of the following statements is true? (Please check all correct answers.) A basic solution has m basic variables (BVs) and (nm) nonbasic variables (NBVs). In a basio feasible solution, all variables are nonnegative. A basic solution has (nm) basic variables (BVs) and m nonbasic variables (NBVs). A basic feasible solution includes m basic variables (BVs) and n nonbasic variables (NBVs). A basic feasible solution has m basic variables (BVs) and (nm) nonbasic variables (NBVs). A basic solution to the LP model corresponds to an extreme point in its feasible region. In a basic solution, all varlables are nonnegative. A basio feasible solution to the LP model corresponds to an extreme point in its feas ble region.
