Answer:
Step-by-step explanation:
-4/5÷1/3= (-4/5)x(3/1)= -12/5=-2 2/5
Answer:
24
Step-by-step explanation:
really need more information about the subject, but im assuming its just basic addition.
36-12=24
The equation should be y=2x+4
Answer with explanation:
Coefficient of determination(r²), is defined as, how well the data values are associated with each other when Regression line is drawn. In regression analysis, the coefficient of determination measures , how well the regression predictions approximate the real data points, means it measures the closeness between two variables.The Value of r², lies between 0 to 1. If value of r²=1, it shows ,regression line that is data values are Perfectly associated with each other.
If ,r²=0, it means there is no variation between two variables.There is 0% variation between two variables.
→Coefficient of Variation=[Correlation coefficient]²
=r²
=(0.854)²
=0.854 × 0.854
=0.729316
=0.730(Approx)
