The following day, his stand was open for regular customers, selling root beer glasses for 5 cents (equivalent to $0.88 in 2023). [ 13 ] [ 14 ] The following year, Allen opened a second stand in Stockton, California . [ 12 ]
As another example, in a population where the lowest 50% of individuals have no income, and the other 50% have equal income, the Gini coefficient is 0.5; whereas for another population where the lowest 75% of people have 25% of income and the top 25% have 75% of the income, the Gini index is also 0.5.
The ICRU sphere phantom is based on the definition of an ICRU 4-element tissue-equivalent material which does not really exist and cannot be fabricated. [11] The ICRU sphere is a theoretical 30 cm diameter "tissue equivalent" sphere consisting of a material with a density of 1 g·cm −3 and a mass composition of 76.2% oxygen, 11.1% carbon, 10. ...
One radian is defined as the angle at the center of a circle in a plane that subtends an arc whose length equals the radius of the circle. [6] More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, =, where θ is the magnitude in radians of the subtended angle, s is arc length, and r is radius.
In the circuit involving Q16 (variously named rubber diode or V BE multiplier), the 4.5 kΩ resistor must be conducting about 100 μA, with Q16 V BE roughly 700 mV. Then V CB must be about 0.45 V and V CE at about 1.0 V. Because the Q16 collector is driven by a current source and the Q16 emitter drives into the Q19 collector current sink, the ...
Even though Ireland has particularly small magnitudes (3 to 5 seats), results of STV elections are "highly proportional". [25]: 73 [5] In 1997, the average magnitude was 4. Eight parties gained representation, four of them with less than 3% of first-preference votes nationally.
Chiu-chang suan-shu or The Nine Chapters on the Mathematical Art, written around 250 BC, is one of the most influential of all Chinese math books and it is composed of some 246 problems. Chapter eight deals with solving determinate and indeterminate simultaneous linear equations using positive and negative numbers, with one problem dealing with ...
