In particular, the quantile is 1.96; therefore a normal random variable will lie outside the interval in only 5% of cases. The following table gives the quantile z p {\textstyle z_{p}} such that X {\textstyle X} will lie in the range μ ± z p σ {\textstyle \mu \pm z_{p}\sigma } with a specified probability p {\textstyle p} .
The Sykes–Picot Agreement (/ ˈ s aɪ k s ˈ p iː k oʊ,-p ɪ ˈ k oʊ,-p iː ˈ k oʊ / [1]) was a 1916 secret treaty between the United Kingdom and France, with assent from Russia and Italy, to define their mutually agreed spheres of influence and control in an eventual partition of the Ottoman Empire.
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.
Every prime number p divides a Fibonacci number that can be determined by the value of p modulo 5. If p is congruent to 1 or 4 modulo 5, then p divides F p−1, and if p is congruent to 2 or 3 modulo 5, then, p divides F p+1. The remaining case is that p = 5, and in this case p divides F p.
Nuclear power's contribution to global energy production was about 4% in 2023. This is a little more than wind power, which provided 3.5% of global energy in 2023. [167] Nuclear power's share of global electricity production has fallen from 16.5% in 1997, in large part because the economics of nuclear power have become more difficult. [168]
As of 2018, there are over 5.3 million vehicles operating in the city, of which 4.3 million are two-wheelers and 1.04 million four-wheelers. [296] The large number of vehicles coupled with relatively low road coverage—roads occupy only 9.5% of the total city area [ 90 ] : 79 —has led to widespread traffic congestion [ 300 ] especially since ...
Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 745 million (about 10% of the world population ) in 2021; the third-largest after Asia and Africa.
