There is a set of ground elements e = {e1, e2, . . , en} and a collection of m subsets s1, s2, . . , sm of the ground elements (that is, si ⊆ e for 1 ≤ i ≤ m).the goal is to select a minimum cardinality set a of ground elements such that a contains at least one element from each subset si. give a polynomial time algorithm for this problem or state the decision version of this problem and prove that it is np-complete.

Suppose that a monopolistically competitive restaurant is currently serving 260 meals per day (the output where mr

Identify whether the statements are true or false by dragging and dropping the appropriate term into the bin provided. long-run economic growth is unlikely to be sustainable because of finite natural resources. in the modern economy, countries that possess few domestic natural resources essentially have no chance to develop economically. finding alternatives to natural resources will be very important to long-term economic growth. in the modern economy, human and physical capital are generally less important in productivity than natural resources. in the 19th century, countries with the highest per capita gdp were nearly always abundant in minerals and productive farming land.

Krier industries has just completed its sales forecasts and its marketing department estimates that the company will sell 43,800 units during the upcoming year. in the past, management has maintained inventories of finished goods at approximately 3 months' sales. however, the estimated inventory at the start of the year of the budget period is only 7,300 units. sales occur evenly throughout the year. what is the estimated production level (units) for the first month of the upcoming budget year?
