Solve for x in both!!!!!
zvonat [6]

Answer:

- 2(x - 2) - 4x = 3(x + 1) - 9x \\  - 2x + 4 - 4x = 3x + 3 - 9x \\ 9x - 3x - 2x - 4x = 3 - 4 \\ 9x - 9x =  - 1 \\ 0x =  - 1 \\ 0 =  - 1

So ; No solution

___o___o____

5(x + 2) - 3 = 3x - 8x + 7 \\ 5x + 10 - 3 =  - 5x + 7 \\ 5x + 7 =  - 5x + 7 \\ 5x + 5x = 7 - 7 \\ 10x = 0 \\  \\ x =  \frac{0}{10}  \\  \\ x = 0

I hope I helped you^_^

Which of the following summary measures for forecast errors does not depend on the units of the forecast variable? a. MFE (mean
Orlov [11]

Answer:

d. The mean absolute percentage error (MAPE) does not depend on the units of the forecast variable.

Step-by-step explanation:

A forecast error is the difference between the actual or real and the predicted or forecast value of a time series or any other phenomenon of interest. Here “error” does not mean a mistake, it means the unpredictable part of an observation.

There are many different ways to summarize forecast errors in order to provide meaningful information.

Scale-dependent errors. The forecast errors are on the same scale as the data. The two most commonly used scale-dependent measures are based on the absolute errors or squared errors:

\begin{align*}  \text{Mean absolute error: MAE} & = \text{mean}(|e_{t}|),\\  \text{Root mean squared error: RMSE} & = \sqrt{\text{mean}(e_{t}^2)}.\end{align*}\text{Mean absolute error: MAE} & = \text{mean}(|e_{t}|),\\  \\\text{Root mean squared error: RMSE} & = \sqrt{\text{mean}(e_{t}^2)}.

Percentage errors. Percentage errors have the advantage of being unit-free, and so are frequently used to compare forecast performances between data sets. The most commonly used measure is:

\text{Mean absolute percentage error: MAPE} = \text{mean}(|p_{t}|).
