Vanyuwa [196]

$120\frac{mile}{hour}\\\\
1 \ mile=5280\ feet\\
1\ hour=3600\ seconds\\\\
120\frac{mile}{hour}=120*\frac{5280}{3600}=\frac{120*5280}{3600}=\frac{633600}{3600}=176\frac{feet}{second}\\\\
\boxed{120\frac{mile}{hour}=176\frac{feet}{second}}$

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
