Answer:
The equation is not a linear function.
Answer:
x = ± 8
Step-by-step explanation:
Given
4x² - 256 = 0 ( add 256 to both sides )
4x² = 256 ( divide both sides by 4 )
x² = 64 ( take the square root of both sides )
x = ± 
= ± 8
Solutions are x = - 8, x = 8

Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
