Do you want to own your own candy store? wow! with some interest in running your own business and a decent credit rating, you can probably get a bank loan on startup costs for franchises such as candy express, the fudge company, karmel corn, and rocky mountain chocolate factory. startup costs (in thousands of dollars) for a random sample of candy stores are given below. assume that the population of x values has an approximately normal distribution. 98 180 125 91 75 94 116 100 85 (a) use a calculator with mean and sample standard deviation keys to find the sample mean startup cost x and sample standard deviation s. (round your answers to one decimal place.) x = thousand dollars s = thousand dollars (b) find a 90% confidence interval for the population average startup costs μ for candy store franchises. (round your answers to one decimal place.) lower limit thousand dollars upper limit thousand dollars

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

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.
