Function question

Draw arrow diagrams to give an example in each of the following cases or explain why you cannot do that. (a) A function that is surjective but not injective. (b) Two functions f and g such that g◦f is bijective but both functions are not bijective.

Discussion 2

A dart of mass 22g is travelling at 7ms-^1 when it strikes a board. How thick must the board be to prevent the point of the dart reaching the wall behind the board? Assume the resistive force exerted by the material of the board is constant and of value 20N.

Complete the Redistricter code to perform the following functions. Implement the MCMC process that iteratively produces candidate redistricting plans

Complete the Redistricter code to perform the following functions. Implement the MCMC process that iteratively produces candidate redistricting plans and accepts or rejects these candidates based on the Metropolis criterion. Run this process at least 1,000 times and record each run’s resulting plan. Visualize the results of this simulation in a plot that displays the …
