Answer:
The mean absolute deviation (MAD) of her Math scores would be 1.2.
Step-by-step 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

Answer:
x = -1
Step-by-step explanation:
<h2>
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get <u>x = -1</u>
