11.) The physics class took two tests. On the first test, the mean score was 72 with a standard deviation of 5. On the second test, the mean score was 80 with a standard deviation of 6. Cindy made an 82 on the first test and an 87 on the second. On which test did she do better relative to the rest of the class?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
