To simplify a ratio, you have to find the common greatest factors between both variables on each side. In this case, 25:16 is the simplist form and could never be minimized to 5:4.
Answer:
Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for 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.
