in a clinical trial, 1818 out of 876876 patients taking a prescription drug daily complained of flulike symptoms. suppose that it is known that 1.81.8% of patients taking competing drugs complain of flulike symptoms. is there sufficient evidence to conclude that more than 1.81.8% of this drug's users experience flulike symptoms as a side effect at the alpha equals 0.1α=0.1 level of significance?

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
