5. You were given the following data on two different but closely related subspecies of alligators, one from Florida, the other from Texas. Write (in python) a single layer perceptron that can detect the origin of alligator, given weight and length. Use only basic data libraries, like pandas. In particular, you should write your own back propagation algorithm and clearly indicate in your comments where it is. (You do not have to report accuracy, but you might want to note it). Weight (kgs) Length (in) Origin 11 70 T 35 11 F 21 45 T 60 80 F 37 32 F 26 64 T 44 30 F 12 60 T

LS = 5 x w (Labor supply) LD = 110 - 0.5 x w (Labor demand) where w = wage expressed in dollars per hour and LS and LD are expressed in millions of workers. The equilibrium wage is $ \boxed{} and the level of employment is \boxed{} million workers. (Enter your responses as integers.) Assume that there is a shock to the economy, such that the labor demand curve is now described by the equation: LD = 55 - 0.5 x w If wages are flexible, the new equilibrium wage is $ \boxed{} and the level of employment is \boxed{} million workers. (Enter your responses as integers.) Now assume that wages are rigid at $20 per hour. Employment at $20 per hour is \boxed{} million workers, and there are \boxed{} million workers unemployed. (Enter your responses as integers.)
