Find a common denominator in the two fractions before you can do anything
Hi lovely,
The answer you're looking for is 21.
The correct answer is 25.12 cubic inches
For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:
5+10+12+4+6+11+13+5 then divide that by 8
The answer to your question is: 8.25
