Answer:
Calculate Mean Absolute Deviation (M.A.D)
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|.
The product of (x1)^2 is 20
The value of x is 9.
We have : - 25 = 7 - (5x - 13)
We have to find the value of x.
<h3>If f(x) = g(x), than what do you understand by true solution of this equation?</h3>
The true Solution of the equation is the value of x for which LHS = RHS.
For example - if ax + b = cx + d , then
ax - cx = d - b
x = is the true solution of the equation.
In the question given -
- 25 = 7 - (5x - 13)
- 25 = 7 - 5x + 13
5x = 45
x = 9
Hence, the value of x for which LHS = RHS is 9.

Equation would be: 25.15 - 1.75x
Where, x = number of days.
Substitute for x = 3,
= 25.15 - 1.75(3)
= 25.15 - 5.25
= 19.90
In short, Your Answer would be $19.90
Hope this helps!
