Find the mean absolute deviation of the set of data. 1,4,7,8,10

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.

step-by-step explanation:

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
