Answer:

A. 0.3204    B. $14.669

Explanation:

Mean = 8.9      SD = 4.5

Required probability = P (X >/= 550/50)

P(X>/=11) = 1 - P[(X - mean/SD) < (11 - mean)/SD]

              = 1 - P(Z < (11-8.9)/4.5)

P(X>/=11) = 1 - P(Z < 0.4666667)

Using Excel NORMDIST(0.4666667,0,1,1)

P(X>/=11) = 1 - 0.6796 = 0.3204

The probability that she will earn at least $550 = 0.3204

b. P ( X  >  x )  =  0.10

1  −  P ( X  −  mean)/SD  ≤  (x  −  mean) /SD = 0.10

P ( Z  ≤  z )  =  0.90

Where,

z  =  (x  −  mean )/SD

Excel function for the value of z:

=NORMSINV(0.9)

=1.282

Hence (x - mean)/SD = 1.282

= (x - 8.9)/4.5 = 1.282

x = (1.282*4.5) + 8.9

x = 14.669

He earns $14.669 on the best 10% of such weekends.

Suppose the government wants to reduce the total pollution emitted by three local firms. Currently, each firm is creating 4 unit
murzikaleks [220]

Answer:

yep

Explanation:

Suppose the government wants to reduce the total pollution emitted by three local firms. Currently, each firm is creating 4 units of pollution in the area, for a total of 12 pollution units. If the government wants to reduce total pollution in the area to 6 units, it can choose between the following two methods:

Available Methods to Reduce Pollution

1. The government sets pollution standards using regulation.

2. The government allocates tradable pollution permits.

Each firm faces different costs, so reducing pollution is more difficult for some firms than others. The following table shows the cost each firm faces to eliminate each unit of pollution. For each firm, assume that the cost of reducing pollution to zero (that is, eliminating all 4 units of pollution) is prohibitively expensive.

Firm X 80 130 210

Firm Y 75 90 130

Firm Z 550 700 1,075

Now, imagine that two government employees proposed alternative plans for reducing pollution by 6 units.

Method 1: Regulation

The first government employee suggests to limit pollution through regulation. To meet the pollution goal, the government requires each firm to reduce its pollution by 2 units.

Complete the following table with the total cost to each firm of reducing its pollution by 2 units.

Firm Total Cost of Eliminating Two Units of Pollution (Dollars)

Firm X

Firm Y

Firm Z

Meanwhile, the other employee proposes using a different strategy to achieve the government's goal of reducing pollution in the area from 12 units to 6 units. This employee suggests that the government issue two pollution permits to each firm. For each permit a firm has in its possession, it can emit 1 unit of pollution. Firms are free to trade pollution permits with one another (that is, buy and sell them) as long as both firms can agree on a price. For example, if firm X agrees to sell a permit to firm Y at an agreed-upon price, then firm Y would end up with three permits and would need to reduce its pollution by only 1 unit while firm X would end up with only one permit and would have to reduce its pollution by 3 units. Assume the negotiation and exchange of permits are costless. Because firm Y has high pollution-reduction costs, it thinks it might be better off buying a permit from firm Z and a permit from firm X so that it doesn't have to reduce its own pollution emissions. What prices is firm Z willing to sell one of its permits to firm Y, but firm X is not?

liraira [26]

Answer:

The indifference point is 10,000 units.

Explanation:

Giving the following information:

Two vendors have presented proposals. The fixed costs are $ 50,000 for proposal A and $ 70,000 for proposal B. The variable cost is $ 12.00 for A and $ 10.00 for B. The revenue generated by each unit is $ 20.00.

Proposal A= 50,000 + 12*x

Proposal B= 70,000 + 10*x

70,000 + 10x= 50,000 + 12x

20000= 2x

10000= x

The indifference point is 10,000 units.

Elm City issued a purchase order for supplies with an estimated cost of $5,000. When the supplies were received, the accompanyin
-Dominant- [34]

Answer:

$5000

Explanation:

Since Elm City issued a purchase order for supplies with an estimated cost of $5,000, although when the supplies were received, the accompanying invoice indicated an actual price of $4,950, the amount that Elm should credit to encumbrances outstanding in its general fund after the supplies and invoice were received; is $5000

Notice that encumbrances are set aside funds for a purpose, therefore upon ordering, encumbrances balance would increase, and Elm would have passed the following entry

Dr. Encumbrances...$5000

Cr. Fund Balance.....................$5000

Therefore even if the supply came with a shortfall in amount, in order for Elm City to show that the purpose for making that encumbrance has been met, it has to be liquidated by crediting the Encumbrance account by the full amount of $5000
