After sticking fast on hot wax in beaker,tied on a thread,pour enough water on the surface of liquid-cork top.The cork was cut away threading by reading the difference in volume=the volume of the cork in Experiment .

(a) When t tends to infinity, e^(-t) and e^(-2t) tend to zero, y = 340/2 = 170. So y cannot exceed 171 in the long run. (b) dy/dt = 340[ - e^(-t) + 4e^(-2t)]/[ 2 + e^(-t) - 2e^(-2t)]^2 Put dy/dt = 0 - e^(-t) + 4e^(-2t) = 0 e^(-t) [ - 1 + 4e^(-t)] = 0 t = infinity or ln 4. when t = 0, y = 340 when t = ln 4, y = 340/(2...

You can input all the bivariate data to your calculator, using the linear regression mode (or 2-variable statistics mode). Then, you can call the values of the correlation coefficient (Pearson) and the slope and intercept estimate of a linear regression accordingly. There are...
