1) Because of population growth, the state of Washington has been given an additional seat in the House of Representatives, making a total of ten. The state legislature, which is currently controlled by the Republicans, needs to develop a plan for redistricting the state. There are 18 major cities in the state of Washington that need to be assigned to 1 of the 10 congressional districts. The next table gives the numbers of registered democrats and registered republicans in each city. Each district must contain between 150,000 and 350,000 of these registered voters. Use Evolutionary Solver to assign each city to 1 of the 10 congressional districts in order to maximize the number of districts that have more registered Republicans than registered Democrats (hint: use the SUMIF function; decision variables must be >=1 and <=10). City Democrat Republican 1 152 62 2 81 59 3 75 83 4 34 52 5 62 87 6 38 87 7 48 69 8 74 49 9 98 62 10 66 72 11 83 75 12 86 82 13 72 83 14 28 53 15 112 98 16 45 82 17 93 68 18 72 98 USING EXCEL AND SUMIF FUNCTION SHOW ALL WORK

Formulas:

E21 =SUMPRODUCT(E3:E20,$D$3:$D$20) copy to E21:N21

O3 =SUM(E3:N3) copy to O3:O20

E23 =SUM(E21:N21)

The assignment of congressional district to each city is indicated by binary variable value equal to 1 in the decision variables matrix (E3:N20)

A) If an economy is in a steady state with no population growth or technological change and the marginal product of capital is greater than the depreciation rate: steady-state consumption per worker would be higher in a steady state with a higher saving rate. steady-state consumption per worker would be higher in a steady state with a lower saving rate. the depreciation rate should be decreased to achieve the Golden Rule level of consumption per worker. the economy is following...

Consider an economy in steady state (or on a “balanced growth path”)without population growth. Suppose that a mysterious new disease (COVID-19) suddenly kills half of the population. We are interested in the effect this likely has on kapital and output per person , both in the short and the long run. How will this affect in the Solow-model? Show with a graph

5. Another equation that has been used to model population growth is the Gompertz equation dP /dt = rP ln (K P ) , where r and K are positive constants, and P(t) > 0. (a) Sketch a clearly labeled graph of f(P), where dP/dt = f(P) (state the main facts you used to obtain your answer). (b) Draw the phaseline. Next to it, sketch a set of integral curves in the t − P plane. (c) State and classify...

Suppose we have a whale population that has been declines to 1000 individuals. The growth rate is 2% a year and the carrying capacity is 10,000. Calculate (use Excel) how many years are needed to have the population recover to 5,000 or more, meaning that during those years, no harvesting can take place. Once the population is recovered, how many whales can be harvested per year in a sustainable way? Can you show me how to put the formula in...
