The slope of the production–possibility frontier (PPF) at any given point is called the marginal rate of transformation (MRT).The slope defines the rate at which production of one good can be redirected (by reallocation of productive resources) into production of the other.

Benford’s law also called the Newcomb–Benford law the law of anomalous numbers or the first-digit law is an observation about the frequency distribution of leading digits in many real-life sets of numerical data.The law states that in many naturally occurring collections of numbers the leading digit is likely to be small. In sets that obey the law the number 1 appears as the leading …
