Step-by-step explanation:

<u>Step 1: Define</u>

<u /> $\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$ <u />

<u />

<u>Step 2: Solve for </u><em><u>x</u></em>

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate <em>x</em> terms: $\displaystyle -12 = 7x - 228$
Isolate <em>x</em> term: $\displaystyle 216 = 7x$
Isolate <em>x</em>: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

Given an actual demand of 64, a previous forecast of 59, and an of .3, what would the forecast for the next period be using simp

BartSMP [9]

Answer: 60.5

Step-by-step explanation:

The forecast for the next period using the simple exponential smoothing method is given by:

$D\times \alpha+F(1-\alpha)$ , where D= actual demand for the recent period, $\alpha=$ smoothing factor, F= forecast for the recent period .

Given: D= 64, $\alpha=0.34$ , F= 59

The forecast for the next period = $64\times0.3+59(1-0.3)$

$\\\\= 64\times0.3+59\times0.7\\\\=19.2+41.3\\\\=60.5$

Hence, the forecast for the next period = 60.5
