The system of equations n=m and n=4 is the point (0,0). which of the following statements is true? a.)no point on the line is n=m is also on the line n=m ,0) is a solution to n=m and to n=4m c.)the graph of the solution is parallel lines d.)every solution to n=m is also a solution to n=4m

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
