Ratio , Proportion , Linear Functions and Functions in General
Ratio and proportion is an ancient topic that is treated in great detail in Euclid’s Elements (300 B.C.). It has been a part of the school curriculum since the earliest “modern” textbooks. For example, Dilworth’s Schoolmaster’s Assistant (1796) includes a description of the so-called “Rule of Three”, which directs one to find the fourth term in a direct proportion by muliplying the second and t...
متن کاملDoes the maxillary anterior ratio in Korean adults follow the Golden Proportion?
PURPOSE The purpose of this study was to determine the effect of changes in the horizontal plane angle on the mesiodistal width ratios of the maxillary anterior teeth during the acquisition of frontal view photographs, derive these ratios for Korean adults on the basis of the data obtained, and analyze them using the Golden Proportion as a reference. MATERIALS AND METHODS In experiment I, 30 ...
متن کاملEstimating the Proportion of "always Buy" and "never Buy" Consumers: a Likelihood Ratio Test with Sample Size Implications
The likelihood ratio test is presented as a natural method to test for the presence of "always buy" and "never buy" consumers. The purchase sequence lengths and sample sizes required to estimate the proportions of these buyers are determined through the use of simulated data. Our method was then applied to two sets of well known data first analyzed by Aaker [1] and Montgomery [8]. The empirical...
متن کاملProportion - share Resource
Proportional-share scheduling has been investigated by many researchers including: Wald-spurger et. al. at MIT and by Stoica et. al. at Old Dominion University. This work, however, suuers from high overhead and limited scalability problems when applied to a distributed system. This paper presents an alternative approach to proportion-share scheduling, which overcomes these problems. Our system ...
متن کاملFirst birth cesarean proportion: A missed indicator in controlling policies
Background: Around one out of two mothers give births by cesarean section (CS) surgery in Iran and about half of this number is due to previous CS. Recently Health Sector Evolution (HSEP) program (started in April 2014) targets the high rate of CS in Iran.
