A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
in mathematics, numerical coefficient refers to the constant multiplicative factors attached to the variables in an expression are known as Numerical Coefficient. It differs from Literal Coefficient.The Numerical Coefficient is always written in front of the variable as shown in the expression given below: , where are numerical coefficients.Numerical Coefficient is more frequently referred as Coefficient.the numerical coefficient for the term 10x4 is 10.The numerical coefficients for the expression 3x2 + x + 1 are 3, 1, and 1.
The literal coefficient is always the "letter" in the term. Therefore in this equation the "Literal Coefficient is "Y"
The strength of the linear relationship between the two variables in the regression equation is the correlation coefficient, r, and is always a value between -1 and 1, inclusive. The regression coefficient is the slope of the line of the regression equation.
