Answer:

28 or 28.11111 because I don't know if it asked you to round or not.

Step-by-step explanation:

Mean is the average of a group of number added together and divided by the number of number there are.

20+22+25+28+29+30+32+33+34 = 253

Now we will divide by the number of numbers we have there are 9 numbers.

Soooo.

253/9= 28.1111111

Answer:

28 1/9 or 28.1111... (0.1 repeating)

Step-by-step explanation:

20 + 22 = 42

42 + 25 =  67

67 + 28 = 95

95 + 29 = 124

124 + 30 = 154

154 + 32 = 186

186 + 33 = 219

219 + 34 = 253

253 / 9 = 28 1/9 or 28.11111...

Hope this helped!
