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
hope this helps :)
-1/35 because you multiply the 2 denominators and numerators together. -1 times 1 is -1, 7 times 5 is 35. Make that as a fraction to get -1/35.
Answer:
c
Step-by-step explanation:
The red one is (4.1) and the green one is (-2.4) because is positive to negative so the positive side is that you got and the negative part is you owe someone for example: -20 < 30 so if it says Emily goes to the store and the milk costs $30.99 and she only has $10.00 that means that she owes $30.00 so is -10 <30
