Coefficients are the numbers directly in front of a variable. Variables are letters in place of numbers in a mathematical problem . For example the expression, "2x" has a variable and a coefficient. The variable is the letter x, and the coefficient is the number 2. The coefficient is NEVER a letter, and is always a number. Coefficients and variables can be used in both scientific and algebraic expressions.

In 3x the 3 is called?
While 3 is a number multiplying, it's a coefficient. That has x as is its factor.
What is the coefficient of restitution in elastic inelastic and plastic collision?
With a plastic impact, the coeffecient of restitution is 0. With an elastic impact, the coeffecient of restitution is 0<e<1. With an inelastic impact, the coeffecient of restitution is 1.
What is the number that proceeds a variable called?
Coeffecient.
Can the coeffecient of skewness be more tan 1?
Yes
What is the coefficient of -x?
The numerical coeffecient of -x is -1.
What is the numerical coefficient of -x?
The numerical coeffecient of -x is -1.
What does it mean if the correlation coeffecient is plus 1.67 in relation to playing mozart during pregnancy and a childs future intelligence?
that there is a strong relation
What do you mean by negative temperature coffecient of silicon?
It strictly means the temperature coeffecient of a particular property of silicon: as the temperature rises, the value of this property falls. Such as electrical resistance.
How do you balance the chemical equation CO2 C--CO?
the chemical equation CO2 C--CO.it is balANCEd by :there are 2 carbons on reactants and 2 atoms of oxygen by putting 2 as coeffecient on product side,equationis balanced.CO2 + C --------> 2CO
How does sandpaper slow thing down?
All materials have a property called the coeffecient of kinetic friction. When this property is high, a higher friction force resists the motion of objects across the surface. Sandpaper has a higher coefficient of kinetic friction as compared to something like ice. This is because ice is smooth whereas the surface of sandpaper is very rough which increases the friction it causes.
Is Coefficient of correlation is independent of change of origin and scale?
The Coeffecient of corelation is definitely independent of origina and scale. If r(x,y)= cof or cor b/w X and Y let W=aX+b and Z=cY+d then r(x,y)=r( W,Z) Note that adding or subtracting a constant in all values of a random variable changes its scale. While multiplication or division change scale. The Form W=aX+b, caters the change both in origin and scale.
Coefficient of friction of road and tire?
The coefficient of friction between a road surface and a tire is a measure of how well the tire grips the road. It is influenced by factors like the type of road surface, the condition of the road, the tire material, and the tire tread design. A higher coefficient of friction indicates better traction and grip between the tire and the road surface.
