Essential Understandings Project: Ratios, Proportions, and Proportional Reasoning (Gr. 6 – 8)Lobato, JEllis, A.B
Proportions or equivalent ratios are often used to determine quantities, particularly in calculating dosages. Consider the following examples. a) If a patient’s heart beat is recorded as 20 beats in 15 seconds, i.e. 20:15, it is possible to determine the number of beats per minute (60 ...

Presenters can add extra information, and the ring shape helps to declutter the graph. Pie charts are used in business to show percentage distribution, compare relative sizes of categories, or present straightforward data sets where visualizing ratios is essential. Real-Life Application of Pie ...

individuals are relatively low. Spherical HDL particles exhibit considerable heterogeneity in diameter, ranging from 7 nanometers (nm) to 14 nm [36]. This heterogeneity is also evident in the significant differences among particles in lipid proportions, protein ratios, and types of apolipoproteins ...
These models were meticulously employed to ascertain hazard ratios (HRs) alongside their corresponding 95% confidence intervals (CIs). The objective was to unveil the potential associations between the characteristic factors and the survival statuses of the patients. Furthermore, to estimate the overall...
Combining primary colors in different proportions gives rise to secondary colors, while mixing a primary and a secondary creates a tertiary shade. Think of it like mixing paints - the possibilities are endless. But color is more than just scientific ratios. It evokes profound...
A forest plot and M 1 . Full size image If the outcome is a time-to-event variable or a continuous variable, the meta-analysis is typically performed on the estimated hazard ratios or means, respectively. Choice of M2: how much are we willing to lose? As the EMA Guidance document stres...
Rapidly developing nanotechnologies and their integration in daily applications may threaten the natural environment. While green methods of decomposing organic pollutants have reached maturity, remediation of inorganic crystalline contaminants is major
