A store manager is looking at past jewelry sales to
determine what sizes of rings to keep in stock. The list
shows the ring sizes purchased by the last ten jewelry
customers.
9,7, 6.5, 7.5, 7, 8, 5, 6, 7.5, 8

answer:

7, and -7

Step-by-step explanation:

you find the mean, median, and mode, then you subtract 7 from the mean, and multiply it by 4

you get 7, then square root it and raise it to the power of 90000000, and you get 1.375*10^931 and you divide it by 349485859 to get 7, but you also need -7
