8 plus 4 is 12 and 8 would be twice as much as 4 which is the tens place
The measure in linear-regression analysis that provides the percent of variation in the dependent variable as explained by the regression equation is the Coefficient of Determination.
<h3>What is the Coefficient of Determination?</h3>
This is a measure that allows us to see just how much the variation in the dependent variable, is as a result of the independent variable and is therefore explained by the regression equation.
The Coefficient of Variation is very important because it helps to show the usefulness and accuracy of the regression equation model.

Answer:
8z^3-36z^2+54z-27
Step-by-step explanation:
(2z-3)^3
(2z)^3*(2z)^2*3+3*2z*3^2-3^3
8z^3-3*4z^2*3+3*2z*9-27
8z^3-36z^2+54z-27
x+4+3x=72
4x+4=72
4x=72-4
4x=68
4x/4=68/4
x=17
