(a) Direct material MIX variance for each material using the formula:[Actual quantity of material used-standard quantity]x[Weighted average standard price per kg-Standard price per kg of the material used] Material A=[2,000-3000]x[$7.50-$5.00]=$2,500A. Material B=[3,000-3,000]x[$7....
Based on their projection, ABC, Inc. bought 800 pounds of material X. The company ended up producing 350 units using all of the material X that it purchased. Using the above formula, we can plug in the given values: Direct materials mix variance = $5 x (350 – 500) ...

change in the spectrum is a shift it might not be detected by simply monitoring the amplitude of the time series. However, an additional peak in the spectrum would be linked to an increase in variance of the time series, even though this would be more difficult to detect at an early ...
A material, which consists of the same type of atoms, is considered. When the magnetic field is applied to the z direction (quantized axis of spin), the average value (or expectation value) of the spin operator Si has a z component 〈Sz〉 only. The magnetization is now written as M=...
This ensures an even bin distribution by assigning a very small random variance factor to ties prior to ranking; so for the purpose of assigning values to the ranked bins, there are no tied values. This process has no effect on the original values. It is only used to disambiguate ties. ...
(GraphPadSoftware, La Jolla, CA, USA) software. The differences between two groups were determined by Student’sttest or Mann–WhitneyUtest when variance was different between groups. Explant and mDA cell intersection profiles were analyzed by two-way analysis of variance, and the Sidak test was...
1-β = 0.80,R2 = 0.16 (adjusted for multivariate covariates),Re(reliability) = 0.95, and variance inflation factor (VIF) = 1.18. The results show that given the proposed sample size, it is possible to detect differential R-REM reporting incidence rates ofλ0 = 0.25...
As a further check we calculated the variance inflation factors (VIF) for the explanatory variables in each model. All VIF values (summarized in Table 4) fall below the recommended cut off of 5 (O’Brien, 2007), suggesting multi-collinearity is not of concern. Table 3. Correlation matrix:...
Many types of dusts are generated from processes and those properties are in a variety depending on the process and material. Therefore, suitable treatment process is necessary for each dust. Ironmaking and steelmaking dusts are classified into two types from the viewpoint of process, one the BF...
