Ages of cousins

What is the mean of the numbers?

Answer 1

To calculate the mean age of the cousins, we first need to sum the ages of all the cousins and then divide by the number of cousins.

Based on the provided ages:

• Maureen: 0 years
• Antonio: 1 year
• Sarah: 2 years
• Charlotte: 3 years
• Noah: 4 years

Now we sum these ages:

0 + 1 + 2 + 3 + 4 = 10

Next, we count the number of cousins, which is 5.

Now, we calculate the mean:

Mean = Total sum of ages / Number of cousins
Mean = 10 / 5 = 2

Therefore, the mean age of the cousins is 2 years.
