Higher-order linear equations work exactly like first and second-order, just with additional roots. Here are some practice problems to demonstrate this. There is nothing new here, just more terms in the equations. You need to factor into linear and/or quadratic terms and apply the techniques described above.
Objectives Nursing is a safety critical activity but not easily quantified. This makes the building of predictive staffing models a challenge. The aim of this study was to determine if relationships between registered and non-registered nurse staffing levels and clinical outcomes could be discovered through the mining of routinely collected clinical data.
