Correct Answer: C) Union of European Football Associations

Explanation

UEFA stands for Union of European Football Associations. This organization is responsible for organizing and regulating football (soccer) competitions in Europe. It was founded in 1954 and is made up of 55 member associations. UEFA's main competition is the Champions League, which features the best club teams from across Europe. UEFA also organizes the Europa League, the European Championship (which is a tournament for national teams), and several other competitions.

It is important to note that while options A and B have the words European and Associations in them, they are not the correct answer as they do not include the word Football. Option D mentions English instead of European, which is also incorrect. Therefore, option C, Union of European Football Associations, is the correct answer.

Correct Answer: A) Total cost equals variable cost

Explanation

This Economics question is asking you to choose which statement among the options is false when considering the long-run.

Option A states that total cost equals variable cost, and this statement is false in the long-run. In the long-run, all costs are variable costs, including fixed costs. So, Option A is the correct answer.

Option B states that average cost equals average variable cost. This statement is true in the long-run because both average cost and average variable cost include all costs, including variable costs and fixed costs.

Option C states that average fixed cost equals zero. This statement is false in the short-run because fixed costs are divided by a smaller quantity of output. However, in the long-run, fixed costs are spread over a larger quantity of output, so average fixed cost approaches zero.

Option D states that average cost is the addition of average fixed cost and average variable cost. This statement is true in the long-run because average cost includes all costs, both fixed and variable.

In summary, the correct answer to this question is Option A, which states that total cost equals variable cost in the long-run. This is false because in the long-run, all costs are variable costs, including fixed costs.

Correct Answer: B. 63.167

Explanation

Put 1 + (0.998) = 1 + x;

x = (0.998)

Hence; 1 + 6(0.998) + 15(0.998)(0.998)\(^2\) + 20(0.998)\(^3\) + 15(0.998)\(^4\) + 6(0.998)\(^5\) + (0.998)\(^6\)

= 1 + 5.988 + 14.790 + 19.880 + 14.880 + 5.940 + 0.990
