Answer 1

Answer: I'm guessing but the answer should beD. 8.8.Tell me if I'm wrong. But at least I tried.

Explanation:

Answer 2

The mean absolute deviation (MAD) of her Math scores would be 1.2.

Explanation:

Mean: 5.4 + 6.4 + 7.8 + 8.8 = 28.4/4 = 7.1

7.1 - 5.4 = 1.7

7.1 - 6.4 = 0.7

7.1 - 7.8 = 0.7

7.1 - 8.8 = 1.7

Mean Absolute Deviation: 1.7 + 0.7 + 0.7 + 1.7 = 4.8/4 = 1.2

hope this helps :)
