Use PYTHON code to answer the following:
Three disease-carrying organisms decay exponentially in seawater according to the following model:
p(t) = Ae^(-1.5t) + Be^(-0.3t) + Ce^(-0.05t)
Using general linear least-squares, estimate the initial concentration of each organism (A, B, and C) given the following measurements and print these:
Determine the St, Sr, and r^2 values, then state whether this is a good mathematical fit and why you believe that.
