faltersainse [42]

Answer:

True

Explanation:

According to MM, without taxes, the market value of the company is not affected by capital structure. As a result, the WACC is unaffected by capital structure. Here, the value of a company is determined by cash flows.

laiz [17]

Answer:

N = 3,120 (Approx)

Explanation:

Given:

z- score for 99% confidence = 2.58

Proportion (P) = 75% = 75 / 100 = 0.75

E = 2% = 0.02

Q = 1 - P = 1 - 0.75 = 0.25

Computation:

N = (Z/E)^2 \times pq

N = (2.58/0.02)^2 \times (0.75 \ times 0.25)

N = (129)^2 \times (0.1875)

N = (16,641) \times (0.1875)

N = 3,120.1875

Therefore, N = 3,120 (Approx).

Naya [18.7K]

Answer:

The correct answer is: "People are rational".

Explanation:

Economics is the study of people's rational options when faced with scarcity and uncertainty, and that happens to all of us. The problem is that people are hardly rational, because our nature often acts against our economic interests.

Not long ago and until today, the work is done during the day, that is, Monday through Friday; A reality for most people. However, much of the economic activity, both ours and the entire world, operates 24/7. Today, millions of workers have unpredictable schedules. This is especially common in jobs related to services and retail sales. For example, many chain stores use personnel algorithms with traffic and apparently this makes sense, but shareholders always expect efficient efforts to maximize profits. If not, however difficult it is, particularly for workers, to get another job.
