Answer 2

Answer:

18

Step-by-step explanation:

mean is the average of all your numbers combined

first you add all your numbers together to get a bigger number then you want to count how many numbers there are and divide by that so

10+5+12+19+25+17+40=128 / 7 (because there is 7 numbers)

128/7 equals 18.28 you round that to get 18.3 but just leave the three off if your teacher says you can
