The bottle of maria’s favorite sports drink says that it holds 20 fluid ounces. maria suspects that the sports drink actually holds a different amount. maria takes a random sample of 25 bottles and measures the number of fluid ounces in each bottle. the mean fluid ounces of maria’s sample of 25 sports drinks is 21.5 fluid ounces. assume that the standard deviation of fluid ounces for the entire population of sports drinks is 2 fluid ounces. true or false? finding a random sample with a mean this high in a population with mean 20 fluid ounces and standard deviation 2 fluid ounces is very unlikely.

i dont know it

step-by-step explanation:

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.
