For a given data group, simple exponential smoothing is being used to forecast demand. The forecast of a given period is 110, wh

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:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}$

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:

$s_t=\alpha x_t+(1-\alpha)s_{t-1}\\\\109.2=\alpha*106+(1-\alpha)*110\\\\109.2=(106-110)\alpha+110\\\\(110-106)\alpha=110-109.2=0.8\\\\4\alpha=0.8\\\\\alpha=0.2$

Given the points (0,6) and (2,8), what is the equation of the line

Citrus2011 [14]

Answer:

y=x+6

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-6)/(2-0)

m=2/2

m=1

y-y1=m(x-x1)

y-6=1(x-0)

y-6=x-0

y-6=x

y=x+6

In a football tournament, each team played exactly 19 games. Teams get three points for everyone and one point for every time. A

irinina [24]

We can actually deduce here that when the tournament ended, team Olympus have tied for 13, 10, 7, 4, 1 times.

<h3>What is inequality?</h3>

In Mathematics, inequality is used to express or show quantities that are less than, greater than, greater than or equal to, less than or equal to.

The following can be seen in inequality expressions:

Looking at the question, we can see that each team plays exactly 19 games.

Every win (w) = 3

Every tie (t)= 1

Every loose = 0

But Olympus got a total of 28 points

Thus: 3w + t = 28 ---------(1)

Note that each team plays 19 games

Thus, T + W ≤ 19 --------------(2)

and T , W ≥ 0

Looking at equation (1) and (2)

=> 2W ≥ 9
