You are part of a school team planning a charity dog wash. You want to use data from last year's dog wash to predict how long it will take to wash a dog this year.

Last year's dog washing team kept track of how long it took to wash each dog. It took the team 15 minutes, 20 minutes, 10 minutes, 18 minutes, and 25 minutes to wash the dogs that came in the morning. In the afternoon, four more dogs came to get scrubbed clean. It took the team 10 minutes, 12 minutes, 30 minutes, and 13 minutes to wash these dogs.

Find the mean of the washing times and find the mean absolute deviation of the washing times. If necessary, round to the nearest tenth.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
