The document contains graphs and equations showing the relationship between casein concentration (5 g/L, 10 g/L, and 40 g/L), time, and velocity for casein solutions. A linear regression equation is given for each concentration with R2 values ranging from 0.9227 to 0.9447, indicating a strong linear correlation. A final graph plots the inverse of concentration versus the inverse of maximum velocity, along with a linear regression equation and R2 value of 0.9907, showing a linear relationship between the two inverse values.
