I need help I don’t understand

Very simple, just do 805 divided by 7. When finding the mean, you add up the all the values, which they already did. It's 805. After that, you divide by the amount of numbers. There are seven numbers, so you have to do 805/7. Luckily I have a calculator next to me, so that should be 115.

if you need , reply with more info. u.
