Find KL. K X-1 L 12 M

Mathematics
1 answer:
Aneli [31]3 years ago
6 0

Answer:

KL = 9

Step-by-step explanation:

(7 + x - 1)(x - 1) = 12²

(x + 6)(x - 1) = 144

x² -x + 6x - 6 = 144

reduce:

x² + 5x -150 = 0

(x + 15)(x - 10) = 0

x = -15, x = 10

KL = 10 - 1 = 9

Using the data in the table, use the exponential smoothing method with alpha=0.5 and a February forecast of 500 to forecast
Sever21 [200]

Answer:

Step-by-step explanation:

The formula to calculate the forecast could be determine by using the exponential smoothing method :

Ft = F(t-1) +  \alpha [A(t-1) - F(t-1)]

Where ,Ft is the Forecast for period t

F(t-1) is the Forecast for the period previous to t

A(t-1) is the Actual demand for the period previous to t

\alpha = Smoothing constant

To get the forecast for may and june   the above formula with \alpha =0.5 and april forecast of 500 will be used

For march

=500+0.5(520-500)\\\\=500+0.5\times20\\\\=500+10\\\\=510

For April

=510+0.5(535-510)\\\\=510+0.5\times25\\\\=510+12.5\\\\=522.5

For May

=522.5+0.5(550-5225)\\\\=522.5+0.5\times27.5\\\\=522.5+13.75\\\\=536.25

So forecast for May = 536.25
