The feasible region for a linear program is defined by these constraints: 2a - 1b less than or = 0; 1a + 1.5b greater than or equal to 200; a greater than or equal to 0; b greater than or equal to zero; an optimizing student in the management science class is interested in finding the best feasible solution under two different objectives. objective 1 maximizes 4a +b; objective 2 minimizes a+b. which of the following statements is true about this linear program?

Which one of the following statements is true? ddt does not prevent disease from passing from agricultural animals to humans. cost was a major factor in the united states government's decision to ban ddt. many african governments concluded that the potential long-term health effects of ddt were not as serious as the immediate problem of insect control. ddt cannot accumulate in the fat of animals. the ddt ban in the united states has made it very difficult to control agricultural insect pests.
