Categories of qualitative variables must be mutually exclusive and collectively exhaustive

a. true
b. false

Answers

Answer 1

The statement, categories of qualitative variables must be mutually exclusive and collectively exhaustive, is true.

It has been seen that when two events are mutually exclusive, it means that they cannot both occur at the same time. But it does not have to  necessarily imply that one of the two events has to happen. Thus, when two events are collectively exhaustive, it means that one of them is said to occur.

For instance, an event which is said to be both collectively exhaustive and mutually exclusive is said to be tossing a coin. The outcome here must be either heads or either tails. So, these are variables.

Hence, option A is correct.

Answers

The Executive Board is the highest management body of a for-profit organization or of a non-profit organization, as it is charged with the strategic management of the company.

It is a single body in which the management of the legal entity is in the hands of executive directors and the supervision of the management by non-executive directors.  

The governing body has ultimate responsibility for the ins and outs of the organization. It can be held accountable for this by both the shareholders and the supervisory directors.

In addition, if the company is negatively in the news, the board of directors will receive full criticism and possibly have to leave its position. In a number of cases, the members of the governing body can even be held liable if, for example, they are guilty of mismanagement or the organization goes bankrupt.

Answers

Thomas Jefferson led the United States with a reactive and defensive foreign policy during his presidency. He focused on defending American interests and promoting peaceful relations with other nations rather than aggressively expanding American power.

Examples of this approach include the Barbary Wars, where he used a combination of naval blockade, diplomacy, and limited military force to protect American interests; the Louisiana Purchase, which he saw as a defensive move to protect American interests and expand the country's ability to control its own destiny; the Embargo Act of 1807, which banned all American ships from trading with foreign nations to protect American interests, and his advocacy for non-interventionism in foreign affairs, which aimed to avoid becoming entangled in the affairs of other nations.

Answers

According to labeling theory, if Joey begins to internalize the stereotype that he is expected to become involved in a gang because of where he comes from, it is more likely that he will fulfill that expectation.

Labeling theory suggests that people are defined and labeled by others based on their social characteristics, such as race, gender, class, or place of origin. These labels can then influence how individuals are perceived and treated by others, as well as their own self-concept and behavior.

If Joey begins to believe that he is expected to become involved in a gang because of his background, he may start to see this as a natural or inevitable path for him. He may feel pressure to conform to this expectation in order to fit in or be accepted by his peers, or he may feel resigned to this fate and give up on pursuing other goals or opportunities.

Describe the characteristics of mount Kilimanjaro, including its climate.

Answers

Mount Kilimanjaro is a majestic mountain located in northeastern Tanzania, near the border with Kenya. It is the highest peak in Africa, standing at approximately 5,895 meters (19,341 feet) above sea level. The mountain is a dormant stratovolcano composed of three distinct volcanic cones: Kibo, Mawenzi, and Shira. Each cone offers unique features and landscapes.

One of the remarkable characteristics of Mount Kilimanjaro is its diverse climate zones. The mountain spans several ecological zones, including tropical rainforest, heath and moorland, alpine desert, and the glacial summit. As climbers ascend the mountain, they traverse through these distinct climate zones, each with its own unique vegetation and weather patterns. The lower slopes are covered in lush rainforests with a warm and humid climate, supporting a variety of plant and animal species. As climbers reach higher altitudes, the landscape transitions into moorland and alpine desert, characterized by drier conditions and sparse vegetation. Near the summit, the climate becomes extremely cold and inhospitable, with snow and ice covering the peaks.

The climate on Mount Kilimanjaro is influenced by its proximity to the equator and its elevation. Generally, the mountain experiences two rainy seasons, from March to May and from November to December, with precipitation decreasing as climbers ascend. Temperatures vary depending on the altitude and time of day. At the lower slopes, temperatures can range from 20°C to 30°C (68°F to 86°F), while at the summit, they can drop to well below freezing, reaching as low as -20°C (-4°F) or even lower.

The unique climate and ecological zones of Mount Kilimanjaro contribute to its rich biodiversity. The mountain is home to a wide range of flora and fauna, including endemic plant species, birds, mammals, and insects. Despite the challenges posed by the harsh climate and high altitude, Kilimanjaro continues to attract adventurers and nature enthusiasts from around the world, offering them a truly awe-inspiring and diverse natural environment to explore.
