In this paper, for any , we give a formula for the number of representations of as the sum of two weighted squares of units modulo . We resolve a problem recently posed by Yang and Tang.doi:10.1142/S1793042116501098SunCui-FangCheng
What is the difference between the total sum of squares and heteroskedasticity? What is the first step to be performed in the following mathematical expression Sigma(X+2)2 1. Use the multiplication rule to find P(WWC) , where C denotes a correct answer and W denotes a wrong a...
In adding square roots, we combine the like radicals, and the unlike radicals are written as they are. So, if we add 4$\sqrt{2}$ and 2$\sqrt{2}$, it is possible because they are like radicals. We can think of this as follows: “If we have four square roots of 2, and we ad...

(2009), describes a stronger orthogonality property: 3-orthogonal arrays guarantee that columns are not only orthogonal to each other and to the constant column, but also to products of pairs of other columns and to squares of other columns. This effectively means that main effect estimates are...
Some new platinum(II) complexes of 1,1-dimethylallene (dma) of general formula cis-[PtCl2(dma)L](L = PPh3, AsPh3, H2NC6H4Me-p, or SMe2O) have been prepared. They react with aliphatic and aromatic amines to give zwitterionic alkenyl derivatives of the type cis-[PtCl2(Me2CCCH2NR1...
The metal-carbon triple bonds and carbon-carbon triple bonds are both highly unsaturated bonds. As a result, their reactions tend to afford cycloaddition intermediates or products. Herein, we report a reaction of M≡C and C≡C bonds that affords acyclic
The structure was solved by Patterson and Fourier methods and refined by least-squares methods to R = 0.076. The complex has an Re = O bond distance of 1.67(2), and a deprotonated diolate oxygen of the ligand is coordinated in the position trans to the oxo group.doi:10.1080/...
The addition rule for probabilities describes two formulas, one for the probability for either of two mutually exclusive events happening and the other for the probability of two non-mutually exclusive events happening. The first formula is just the sum of the probabilities of the two events. The...
