Romashka [77]3 years ago

Answer:

£103

Step-by-step explanation:

He wants the least waste possible.

So if he buys a 180 cm piece he can make 3*65 cms pieces, with only 6 cm waste.

Now he needs wood for 2*65 and 2*110 pieces which is a total length of

340 cms. That would require  1 * 150 pieces for the 65 cms and 2 for the 110 cm pieces. Total 3 * 150 cm pieces.

Answer is 1 * 180 and 3*150 pieces.

Total cost 28 + 3*25 = 103.

Amiraneli [1.4K]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Mean Absolute Deviation MAD

MAD = \sum_{i=1}^{n} \frac{\left | actual_{i}-forecast_{i} \right |}{n}

Mean squared error  

MSE=\Sigma^{n}_{i=1} \frac{(Actual_i - Forecast_i)^2}{(n - 1)}

linear trend equation is Ft = 124 + 2t

MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\

Naive method

MAD = \frac{36}{9} = 4\\\\MSE = \frac{202}{8}=25.25\\\\MAD (Naive) = 4\\\\MAD (Linear) =2.3\\\\MSE (Naive)=25.25\\\\MSE (Linear)=10.11\\\\

Please find the attached file.
