I think it changes for when the southern people get most of their delegates or maybe when there's most issues going on in the houses of representatives.
The correct answer is option A. 1,18.
Linear regression is a method used to identify the trend Or similarity between two sets of data. All the given points of the data set are plotted and a straight line is drawn with the points. The line is called a line of regression.
F Test is a test that is used to check if the given line of regression is a good fit for the given data set or not. F ratio is the ratio obtained by dividing the two mean square values of the data set.
The numerator of the given regression is always 1
The denominator of the regression is given by n-2=20-2=18.

Answer:
Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.
AND
Examples:
Revolution of Earth around the sun.
Revolution of moon around the earth.
Velocity of a satellite around the earth.
Velocity of a car while driving.
Velocity of a ball when hitted with a bat.
Velocity of water coming from a tap.
Velocity of the train .
Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems.. Formula = ˙ is the characteristic velocity (e.g. m/s, ft/s) is the chamber pressure (e.g. Pa, psi)
