Answer:
8.7
Step-by-step explanation:
To find the mean first you have to add up all the weight of the cats which is:[tex]6+5+9+11+11+10= 52[/tex]
After, you have to divide the total weight by the number of cats there are
which is: [tex]52/ 6=8.66666666667[/tex]
Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7
