Determinant why
WebSocial determinants of health (SDOH) are the conditions in the environments where people are born, live, learn, work, play, worship, and age that affect a wide range of health, functioning, and quality-of-life outcomes and risks. SDOH can be grouped into 5 domains: Economic Stability. Education Access and Quality. Health Care Access and Quality. WebOct 21, 2016 · 17. The determinant was originally `discovered' by Cramer when solving systems of linear equations necessary to determine the coefficients of a polynomial curve passing through a given set of points. Cramer's rule, for giving the general solution of a system of linear equations, was a direct result of this.
