mlc27 Posted June 21, 2020 Share Posted June 21, 2020 1) If every average rating is an arithmetic mean, it means that the total is the (number of travel agents)*(mean score). So in reliability, airline A has a total rating of 780, B has 750 and C 490, adding to 2020. In promptness, they add to 1750. Therefore, we see that reliability ranking totals exceed those for promptness by 270, which is approximately 250. 2) So there are 21 coins. Nickels are worth 0.05 dollars, and quarters 0.25. So letting the number of nickels be n and the number of quarters be q, we must have 0.05n+0.25q=3.05 and n+q=21. Solve these equations by substitution - you should find that n=11, q=10 so the number of nickels is greater. 3) So both faculties have the same number of staff. Let's call this number x. The number of male faculty at school A is 2x/5 and the number of female faculty at school B is 4x/9. Clearly for all x, 4x/9 is bigger than 2x/5 and so the number of female faculty at school B is greater. Quote Link to comment Share on other sites More sharing options...
