Answer:

Option C) 1537

Explanation:

We are given the following in the question:

Population standard deviation = $5000

95% confidence interval width = $500

Thus, margin of error = $250

Formula for margin of error =

z_{stat}\times \dfrac{\sigma}{\sqrt{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

250 = 1.96\times \dfrac{5000}{\sqrt{n}}\\\\n = (1.96\times \dfrac{5000}{250})^2\\\\n = 1536.64\\n \approx 1537

Thus, the correct answer is

Option C) 1537

Answer:

"Why We've Been Hugely Underestimating the Overfishing of the Oceans"

Determining whether each statement is true or false:

a. False

b. True

c. False

d. True

Explanation:

The article "Why We've Been Hugely Underestimating the Overfishing of the Oceans," was published by the Washington Post on January 19, 2016.  It was written by Chelsea Harvey.  It tried to show how the world fish stock had been declining due to overfishing.  This is why it provided a report contrary to the FAO report.  

While the FAO report noted that the peak of worldwide catches was at 86 million tons in 1996, the contrary and independent report, using "catch reconstruction" showed that the peak was at 130 million tons in 1996.  The reconstructed research also showed that worldwide fish catches had suffered declines ever since the 1996 peak, thereby threatening "world food security and marine ecosystems".  The contrary report also suggested that all stakeholders must collaborate so that fish stocks can rebuild naturally.

A tenant rented an apartment, signing a 15-month lease. After the lease expired, the tenant paid 1 month's rent and got a receipt. What kind of leasehold goes the tenant have holdover tenancy

A holdover tenant is a tenant who continues to occupy a rental after the lease has ended. The holdover tenant can continue to occupy the property legally if the landlord accepts rent payments; the length of the holdover renter's new rental term is determined by state legislation and court decisions. The tenant is seen to be trespassing if the landlord refuses to accept any additional rent payments, and if they do not leave right away, an eviction may be required.

  • A holdover tenant is one who keeps making rent payments after the lease has ended. To avoid starting eviction procedures, the landlord must also concur.
  • In a murky space between a full rental agreement and trespassing, holdover tenancy exists. All parties are better protected by even a one-sentence agreement, thus it should be taken into consideration.
  • The month-to-month rental clause that is found in the majority of lease agreements frequently eliminates this problem.

Selecting the best alternative system involves:
MissTica

Answer:

The correct answer is letter "E": both A and B.

Explanation:

At the moment of creating a strategic plan, companies must also outline contingency strategies in case the master plan does not work. These contingency plans work as alternative systems that, just like the master plan, englobe all the activities and steps the firm will follow to keep the business up and running.  

Therefore, the alternative systems also include the resources available the firm counts on to conduct its operations which will also let the company be aware of the limits it has in the for its day-to-day and long-term activities.
