Answers

Answer 1

The slack time for activity e will be 0. The start times, end times, and duration of the different activities.

There are two paths from which the project can be completed.

The first path is :

A ⇔B, B⇔D, D⇔E, E⇔F.

Calculating the slack time for E will require subtracting the finish time from the start time.

The slack time for activity E will be 32 - 32 = 0.

The second path is:

A⇔C, C⇔D, D⇔F

In this path, activity E does not take place.

Slack time tells us how much time we can delay the start of the activity and still get the activity finished on time. When the slack time is 0 then it shows that the activity is critical and cannot be delayed at all.

It is True that a shareholder rights provision discourages takeovers because the acquiring company will suffer dilution.

What is Dilution?

When a firm issues new shares, the proportion of ownership held by current stockholders in the company decreases, a situation known as dilution occurs. When owners of other optionable securities, such as firm workers, or owners of stock option holders exercise their options, more shares may be diluted. Each current stockholder's ownership in the firm decreases as the number of outstanding shares rises, devaluing each share as a result.

If the three families are forced to sell at the perfectly competitive price, what is the price of a unit of oil, and how much oil is produced?

Answers

15 units oil is produced.

Price is $14 and quantity is 15 units a day.

(Cartel maximizes profit according to the rule MR = MC.

At P = 16 and Q = 12; Total Revenue, TR = P×Q = 16×12 = 192

At P = 14 and Q = 15; Total Revenue = P×Q = 14×15 = 210;

So, Marginal Revenue = Change in TR/Change in Q = (210-192)/(15-12) = 18/3 = 6

At P = 12 and Q = 18; Total Revenue = P×Q = 12×18 = 216;

So, Marginal Revenue = Change in TR/Change in Q = (216-210)/(18-15) = 6/3 = 2

So, we can see than MR exceeds MC up to Q = 15 and MR < MC after Q = 15.

Thus, 15 units are produced at $14.
