Answer:
C. 3.2
Step-by-step explanation:
Heights of dogs: 10, 22, 15, 12, 16
✔️Find the mean of the data set = 
✔️Find |data value - mean|:
|10 - 15| = 5
|22 - 15| = 7
|15 - 15| = 0
|12 - 15| = 3
|16 - 15| = 1
✔️Find the sum of |data value - mean| and divide by 10:

✅M.A.D = 3.2
#1. x = - (2y) / (1-y)
#2. x = (-4y-3)/(1-y)
I can't really see the other questions, so I only did the first two. Hope this helps!

Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position
There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C
Multiply those values out: 9*8*7 = 72*7 = 504
There are 504 ways to pick three people from a pool of nine.
Answer: 504
Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer
