The Souls of Black Folk essays by W.E.B. Du Bois were composed during a crucial time in United States history concerning race relations. In 1868 and 1870 the fourteenth and fifteenth amendments passed. Even with these amendments‚ segregation was still in effect‚ particularly in the South. Even though the Southern states had received assistance during the Reconstruction period‚ the region was still feeling the result of the Civil War by the end of the nineteenth century. Race relations echoed antagonism

profits are unbounded. T . MULTIPLE CHOICE – clearly indicate your response. 1. For a linear programming problem‚ assume that a given resource has not been fully used. In other words‚ the slack value associated with that resource constraint is positive. We can conclude that the shadow price associated with that constraint: A. will have a positive value. B. will have a negative value. C. will have a value of zero. D. could have positive‚ negative‚ or zero value.
