11. Maria keeps track of attendance for her student council meetings. For the last 8 meetings, Maria's attendance data are shown.
6,8,8, 12, 16, 13, 11, 15
What is the mean absolute deviation of the data?

30005

yes ok                                            

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
