The answer would be six because if you add them up it would equal 56 then divide that by 7 gives you a mean of 8. hope that helps
It would be four. You can have four negative numbers and they will turn positive. For example, if you had -2 x -2 x -4 x -4 = 64. 64 would be positive because two negative numbers equal a positive number.
Any number in fraction form is over 1, so for a negative number like -29 it would be 29 over negative 1, like this: 29/-1
