Decide whether the statement is true or false. If it is false, tell why.If k is a positive number, then the equation -x2 = -144k has no real solutions.

A. False; the equation is equivalent to x2 = 144k, where x2 and 144k are positive, so it will have two real solutions B. False; the equation is equivalent to x2 = 144k, where x2 and 144k are positive, so the equation will have one real number solution C. True

Solve the problem.A box contains a total of n + 2 light bulbs. In this box, there are 7 defective 40-watt bulbs, 4 defective 60-watt bulbs, and 5 defective 100-watt bulbs. If a light bulb is chosen at random by a quality control inspector, the probability, or chance, of one of the defective light bulbs being chosen is   +  + .Simplify this expression and then use the simplified expression to evaluate n = 98 and interpret the result.

A. ; when there are 100 light bulbs, there are 4 chances in 25 that a defective light bulb is chosen.
B. ; when there are 100 light bulbs, there are 7 chances in 50 that a defective light bulb is chosen.
C. ; when there are 100 light bulbs, there are 8 chances in 25 that a defective light bulb is chosen.
D. ; when there are 100 light bulbs, there are 9 chances in 50 that a defective light bulb is chosen.
