A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another.
Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself.
[3] [4] The Gini coefficient was proposed by Corrado Gini as a measure of inequality of income or wealth . [ 5 ] For OECD countries in the late 20th century, considering the effect of taxes and transfer payments , the income Gini coefficient ranged between 0.24 and 0.49, with Slovakia being the lowest and Mexico the highest.

Income ratios include the pre-tax national income share held by top 10% of the population and the ratio of the upper bound value of the ninth decile (i.e. the 10% of people with highest income) to that of the upper bound value of the first decile (the ratio of the average income of the richest 10% to the poorest 10%).
The following unit conversions may be helpful when considering the data in the tables: 3.6 MJ = 1 kW⋅h ≈ 1.34 hp⋅h. Since 1 J = 10 −6 MJ and 1 m 3 = 10 3 L, divide joule/m 3 by 10 9 to get MJ/L = GJ/m 3. Divide MJ/L by 3.6 to get kW⋅h/L.
Using data from 1960 to 2005, they have found that the Misery Index and the crime rate correlate strongly and that the Misery Index seems to lead the crime rate by a year or so. [10] In fact, the correlation is so strong that the two can be said to be cointegrated , and stronger than correlation with either the unemployment rate or inflation ...
