What is the mean of 49.7 15.8 22.7 15.1 32.2 39.1 27.7 18.1

27.55

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms.

So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4

220.4 / 8 = 27.55

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
