For the mean you just add up all numbers and then divide by how many ever numbers there are. It's really easy, actually. Please mark me as brainliest if I helped you out.

For number three, you would add 1+2+3+4+5+6+7+8+9+10. that equals 55. you then would divide that by 10, as there are 10 numbers. 55÷10=5.5
