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:
Formula: P(A or B)=P(A)+P(B)-P(A or B)
p(c)=7/18
p(s)=6/18
p(c or s)=2/18
0.39+0.33-0.11=
answer:0.61
Answer:
- The statement is <em>false</em>
- There is<em> no solution</em>
Step-by-step explanation:
Step 1: <em>Collect the like terms</em>
2x+7 = -8x-9+10x
2x+7 = 2x-9
Step 2: <em>Cancel</em><em> </em><em>equal</em><em> </em><em>terms</em><em> </em><em>of</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em>
2x+7 = 2x-9
7 = -9
Result: The statement is <em>false</em> and there is <em>no solution</em> as 7 is <em>not equal</em> to -9.

Answer:
(A.
Explanation:
In A, line AD straight into BC, thus creating two 90 degree angles. This means that they are perpendicular.
