What is the mean of 20,28,22,35,47,90
Basile [38]
So add all the numbers together (20 + 22 + 28 + 35 + 47 + 90) and you'll get 242. Then you take the number and divide it by the numbers in your set (you have 6 numbers so you'll divide by 6) 242/6. The answer would be 40.3333333 (repeating decimal). I hope this helps!
