For example, surveying a much larger area of land would reduce uncertainty associated with the average density of social groups.
The average density of salt in Long Island sea water is 35,000 parts per million.
So, quantities that we can compute with double integrals include things like the area of region, its mass if it has a density, the average value of some function, for example, the average value of the x and y coordinates, which we called the center of mass or moments of inertia.
Across the world, it would be a mistake to focus solely on improving the average densities of cities. Los Angeles has a higher average density than New York, for example, yet LA is regarded as a dysfunctional urban form while NY is functional, because it comprises a network of high-density neighbourhoods interconnected by efficient and affordable mass transit systems.
For example, the average lengths of confidence intervals for DA- and DS-related QTLs were narrowed by 60%and47%47 %, respectively, using the high-density map.
For example, it has been shown that, for the Pacific oyster, average density of SNPs is one SNP per 60 bp in coding regions and one per 40 bp in non-coding regions.
For example, the density of water is 1 gram per cubic centimetre, and Earth's density is 5.51 grams per cubic centimetre.
For example, the density of air is 1.2 kilograms per cubic metre.
For example, the density of wood in a palm tree trunk varies, depending on the load it must support.
For example, the NW density, average diameter, and length of sample C are 1.1 × 109 cm−2, 33.1 nm, and 80.9 nm, while those of sample K are 7.0 × 108 cm−2, 88.2 nm, and 963.3 nm, respectively.
