These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
The Organisation for Economic Co-operation and Development defines the employment rate as the employment-to-population ratio. [1] This is a statistical ratio that measures the proportion of a country's working age population (statistics are often given for ages 15 to 64 [2][3]) that is employed. This includes people that have stopped looking ...
For example, the ratio one minute : 40 seconds can be reduced by changing the first value to 60 seconds, so the ratio becomes 60 seconds : 40 seconds. Once the units are the same, they can be omitted, and the ratio can be reduced to 3:2. On the other hand, there are non-dimensionless quotients, also known as rates (sometimes also as ratios).
A person's waist-to-height ratio – occasionally written WHtR [a] – or called waist-to-stature ratio (WSR), is defined as their waist circumference divided by their height, both measured in the same units. It is used as a predictor of obesity-related cardiovascular disease.
English life expectancy at birth reached 41 years in the 1840s, 43 in the 1870s and 46 in the 1890s, though infant mortality remained at around 150 per thousand throughout this period. Life expectancy in 1800, 1950, and 2015 – visualization by Our World in Data.
The most common way to approach related rates problems is the following: [2] Identify the known variables, including rates of change and the rate of change that is to be found. (Drawing a picture or representation of the problem can help to keep everything in order)
1.416 784 (16) × 10 32 k [10] Unlike the case with the International System of Units , there is no official entity that establishes a definition of a Planck unit system. Some authors define the base Planck units to be those of mass, length and time, regarding an additional unit for temperature to be redundant.
As of 2009, the average birth rate (unclear whether this is the weighted average rate per country [with each country getting a weight of 1], or the unweighted average of the entire world population) for the whole world is 19.95 per year per 1000 total population, a 0.48% decline from 2003's world birth rate of 20.43 per 1000 total population.
