The numbers of hours that 12 students say they typically spend on homework in a week are 0,2,8,8,8,8,8,8,10,10,10,10. what is the mean?

7.5 hours

Step-by-step explanation:

The mean is found by adding up the total of the numbers, then dividing the sum over the number of numbers.

Here, it is: (0 + 2 + 8 + 8 + 8 + 8 + 8 + 8 + 10 + 10 + 10 + 10)/12.

That is equal to 90/12, which is equal to 7.5 hours.

i think this could be a possible answer (1 / 84) -1

good luck! : d

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
