Answer:

0.002244

Explanation:

We will first calculate the expected return. It is:  E(r)

E(r) = (0.10 0.21) + (0.70 0.11) + (0.20 0.03)

                  = 0.104

Var = 0.10 (0.21 - 0.104)2 + 0.70 (0.11 - 0.104)2 + 0.20 (0.03 - 0.104)2

= 0.002244

A card from a 52 card deck is lost. We then draw 2 cards from the 51 remaining cards. What is the probability they are both diam
Nonamiya [84]

Answer:

\frac{1}{17}

Explanation:

Let D be the event that the lost card is a diamond

and D' be the event that the lost card is a non diamond

Therefore,

P(D) = \frac{13}{52} = 0.25

P(D') = \frac{39}{52} = 0.75

Now,

Event that the cards picked up are both diamonds = A

Thus,

P( A | D) = \frac{12}{51 }\times\frac{11}{50}               [ As One Diamond Card is lost ]

And,

P(A | D') = \frac{13}{51}\times\frac{12}{50}                [ As One Non-Diamond card is lost ]

Therefore,

P(A) = P(D) × P(A | D) + P(D') × P( A | D')  

= 0.25 × \frac{12}{51 }\times\frac{11}{50}  + 0.75 ×  \frac{13}{51}\times\frac{12}{50}

= \frac{1}{17}

O

D. Part-time employees should be compensated with a salary

because the number of hours they work each month is always the

same.

Explanation:

Part-time workers are called to duty on a need basis.  Usually, part-time workers are assigned specific tasks to perform is within a particular duration. Their contribution is measured in terms of hours worked or completed units of output.

Part-time workers contrast with full-time workers who report for duty every working day. Part-time workers are not required to work for certain hours per week or month like full-time workers. The number of hours that a part-time worker works in a week varies from time to time. Therefore, the best way of compensating them is through an hourly rate.

A focused low-cost strategy ...A) cannot be sustained over time unless the focuser is aggressive in entering other segments wher
alexandr1967 [171]

Answer:

The correct answer are A and E.

Explanation:

Cost leadership is where the company intends to be the lowest cost producer in its industrial sector. The company has a broad picture and serves many segments of the industrial sector, and can still operate in related industrial sectors. The breadth of the company is often important for its cost advantage. The sources of cost advantages are varied and depend on the structure of the industrial sector. They can include the persecution of economies of scale of own technology, preferential access to raw materials.

A successful cost leadership strategy is disseminated throughout the company, as evidenced by high efficiency, low overhead, limited benefits, waste intolerance, thorough review of budget requests, extensive control elements, rewards linked to cost concentration and extensive employee participation in attempts to control costs.

Some risks of following cost leadership is that competitors could mimic the strategy, decreasing the profits of the industry in general; that technological advances in the industry could make the strategy ineffective or that the interest of the buyers could be diverted towards other characteristics of differentiation besides the price.
