Answer:
The smoothing constant alpha is 0.20 (Option a)
Step-by-step explanation:
To solve this problem, first we write the succession of the simple exponential smoothing:
Where s(t) is the forecast for period t, s(t-1) is the forecast for period (t-1), xt is the real demand for period t, and alpha is the smoothing constant.
All but the alpha constant are known
s(t)=109.2
s(t-2)=110
xt=110-4=106
Then, we can calculate alpha as:
X = 8.
We know this since the line in question is vertical, so we automatically know it will be x (vertical lines can only pass through the x axis, because the y axis is already vertical).
Vertical lines will pass through only 1 x-coordinate, but they pass every point on the y-axis, since they infinitely go up and down (which, we already said, is the y-axis).
We are given the function p(x) = 4x for the perimeter of the square.
Where x represents the known side length of the square.
x is the independent variable and Perimeter P is the dependent variable on x.
<em>Because value of P total depends on the value of side length x of the square.</em>
Therefore, following statement are true about the given function:
<h3>The perimeter is the dependent variable.</h3><h3>The value of p(x) depends on the value of x.</h3><h3>The length of the side of the square is the independent variable.</h3>
