Conventionally, the dependent variable is denoted by y, the independent variable(s) by x; and the regression is of y on x.
The coefficient of regression of x on y is a measure of the degree to which variations in y are reflected by variations in x. This does not mean that changes in y cause changes in x since both could be affected by something else entirely.

The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1 What is the coefficient of the squared expression in the parabola's equation?
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.
X is second order and Y is first order X plus Y-- XY Does the reaction occur in a single step in which X and Y collide?
Yes, the reaction occurs in the step where X and Y collide. The first step is part of an elementary reaction and in an elementary reaction, the order is nothing but the coefficient in front of the reactant.
Are the two equations -6 plus y equals 2x and 2y-4x equals 12 dependent?
In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first. So the equations are the same (and therefore dependent).In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first.

Does the equation x plus y equals 41 define y as a function of x?
Both. If you look at it like this: y=41-x you say x is independent and y is dependent of x (i.e. y is a function of x) For x=41-y you say y is independent and x is dependent of y (i.e. x is a function of y)
What is Y x plus 5 Y 6?
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
What is the coefficient of x in 3xy?
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
What is the coefficient of x 12 y 13 in the expansion x plus y 25?
It is 5200300.
What is coefficient of a number?
A coefficient is a factor to a variable in a given expression. While they may be represented with algebraic expressions, they are typically to be treated like constants. For instance, in y = 5x 5 is a coefficient of x. Similarly, in y = ax a is a coefficient of x.
What is the coefficient of y in 5 7y2 x?
Zero. There is no term with just y in it.
What is the formula of correlation coefficient of correlation?
ρx,y=cov(x,y)/sqrt[Var(x)*Var(y)]
Can regression be meassurd?
Regression can be measured by its coefficients ie regression coefficient y on x and x on y.
What is the derivative of -x-y?
If y is a function of x, that is y=f(x), then the derivative of x-y is 1-y' or 1-dy/dx (where y' or dy/dx is the differential coefficient of y with respect to x).
What is the coefficient in 4 plus x equals y?
The only coefficient here is just 1
When is the standard correlation coefficient positive?
Assume that you are correlating two variables x and y. If there is an increasing relationship between x and y, (that is , the graph of y=a+bx, slopes upward), the correlation coefficient is positive. Similarly, if there is a decreasing relationship, the correlation coefficient is negative. The correlation coefficient can assume values only between -1 and 1.
Coefficient of the fourth term of the expansion of x-y to the 6th power?
fourth term of X-Y to the sixth power
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
