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

The new area when new length 2 times the current length and the new width 2 times the current width.

$A=(50\times2)\times(30\times2)=100\times60=6000ft^2$

a. The size of Kaitlin new patio is

$100\times60=6000ft^2$

The Harris family needs to purchase topsoil for their landscaping project (measuring 50 ft x 40 ft with a thickness of 6 inches

lana66690 [7]

50ft x 40ft x 0.5ft = 1,000 ft³ of soil needed for the project

1000/3= 333.3 bags of soil would be needed, so round up to 334.
334 x $2.25 = $751.50

convert the feet³ to yards³, divide the 1000 ft³ by 27 (27 ft³ in 1 yard³)
1000/27= 37.037(repeating) yd³ I'll round up to 38 yd³
38yd³ x $18 = $684 + $50 delivery fee = $734

So, the bulk soil is less expensive by $17.50
