Question

Mandy is working at the zoo. She must record the ages of the tortoises. There are 9 tortoises. Their ages are 29, 2, 12, 26, 18, 34, 54, 44, and 18. What is the mean age of the tortoises? You may use a calculator. Round to the nearest whole number.

Answer 1

26

Explanation:

Mean:

To find the mean of a given data, divide the sum of the data by the number of data.

`\boxed{\bf Mean = (sum \ of \ all \ the \ data)/(number \ of \ data)}`

`\sf = (29+2+12+26+18+34+54+44+18)/(9)\\\\\\=(237)/(9)\\\\\\= 26.3\\\\= 26`

Answer: Mean = 26
