Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only fo
r the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.
y = –477.38 + 237.66 ln x
y = –109.41 + 14.59x
y = 11.46 e1.107x
y = 0.45x1.903
y = –477.38 + 237.66 ln x
y = –109.41 + 14.59x
y = 11.46 e1.107x
y = 0.45x1.903

Step-by-step explanation:
Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,
Addition and subtraction requires that we find a common demoninator.
For example,
The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.
Then we add the numerators
Then we should reduce.
Division is a little trickier because we have to flip-flop the second term and then multiply. For example:
