Answers

Answer 1

Answer:

B.) It is equal to about 1 times the mean absolute deviation of either data set.

Explanation:

Given the scores :

Williams :

89,97, 78, 81, 91

Andre :

90, 74, 73, 87, 82

The mean scores :

Mean = ΣX / n

William's mean score = 436 / 5 = 87.2

Mean absolute deviation :

[|89-87.2| + |97-87.2| + |78-87.2| +|81-87.2| + |91-87.2|] / 5

William's mean absolute deviation = 6.16

Andre's mean score = 406 / 5 = 81.2

Andre's mean absolute deviation =

[|90-81.2| + |74-81.2| + |73-81.2| +|87-81.2| + |82-81.2|] / 5 = 6.16

Difference of the mean = 87.2 - 81.2 = 6

Mean absolute deviation of each dataset = 6.16

The closest relationship between the mean difference and the mean absolute deviation is :

Mean difference is about 1 times the mean absolute deviation

describe how migration in geography influence the history and government of australia and new zealand

Answers

Answer:

Australia and New Zealand are developed countries with high living standards. So, it shouldn't be surprising that they have net migration into their countries. Those levels of migration are carefully controlled using points systems that prioritize highly educated and skilled people who are of value to the country.

The most common origin country is the United Kingdom, since they have strong ties to the UK from the days of the British Empire. They remain commonwealth countries to this day, and still have the Queen on their currency. Between 2004 and 2013, the UK was the greatest source of immigrants to New Zealand, though India and China finally overtook the UK in 2014. It's a similar story in Australia, where only India and China regularly beat the UK in immigration.

Clearly, there are no physical geographical reasons for this migration, since the UK is almost exactly on the opposite side of the world from Australia. People definitely aren't moving from the UK out of convenience. Since most migration to and from both countries relates to reuniting family, migration out of Australia and New Zealand is generally to these same three countries. Nearby countries, like the Philippines and Fiji, are also significant.

Migration to Australia continues to increase year by year. The government limits and quotas are being increased, but this is in response to demand. Without limits, immigration would no doubt be much higher. Immigration in New Zealand has been fairly static numerically, though it saw a significant increase in the early 21st century. Some might argue that this was partly due to the Lord of the Rings movies, which brought the beauty of the country to the attention of people abroad; certainly, it had a dramatic impact on tourism to the country.

Discuss on the major problem of urban centres of ethiopia

Answers

Answer: Urban centers in Ethiopia are ridden by a variety of socio-economic issues such as illiteracy, unemployment, and especially poverty.

Explanation: They can also lack environmental management, lack of stability in infrastructure and buildings, as well as lack of investment in the local human population.  

While there has been an increase in construction, the quality of construction itself has been poor as the government has felt pressure to rapidly build in order to meet demand and immediate needs.  However this can mean very costly rehabilitation of the faulty construction in the future.  

In addition, in urban Ethiopia, women out number men which has contributed to the poverty level as their main source of employment is agriculture.  

Furthermore, many times there is only one main road within the urban centers which contributes to a lack of infrastructure and overcrowds the area.

Finally, there is also a lack of post secondary education and medical facilities.

What is the current state of Communist China in the 21st century?

Answers

Answer:

China’s Communist Party turns a century old this July, a milestone that Beijing is celebrating with a crescendo of fireworks, theatrics and a fervent campaign to honor its revolutionary past.

The party has often lurched between tragedy and triumph between its birth as an underground movement and its current dominance over the world’s most populous nation. It seized power in 1949, and its early decades in government were tumultuous, with Mao Zedong launching radical purges and a disastrous industrial program that led to one of the deadliest famines in history.

Mao’s death in 1976 precipitated political and economic changes under Deng Xiaoping that would transform an impoverished nation into a global economic powerhouse.

Surface features that are created when water dissolves limestone, like sinkholes and disappearing streams, are parts of Group of answer choices a potentiometric surface. a geothermal landscape. a karst landscape. an artesian surface.

Answers

Answer:

The correct answer is ''a karst landscape.''

Explanation:

A karst landscape is due to the erosion of water in limestone, that is, it is the surface of the earth resulting from the action of water on soluble rocks, in a slow dissolution process that takes thousands and even millions of years –approximately 5 mm of advance in the rock every hundred years–. The phenomenon is common in limestone rocks. This type of relief originated from the dragging or accumulation of soluble and disintegrated materials, such as those made up of carbonates. Limestone rock can decompose with water, since it is soluble; this solubility increases with the presence of acids produced by the mixture of CO2 and water, or by organic acids from the microbial activity of the soil. In this way, the limestone rocks fragment and form holes that, over time, give rise to various types and sizes of holes or depressions on the surface.

The map shows the locations of 13 major river basins in Africa: the Senegal, Volta, Niger, Lake Chad, Nile, Lake Turkana, Juba Shibeli, Ogooue, Congo, Zambezi, Okavango, Limpopo and Orange river basins. This spectacular Southern African waterfall, considered to be among the greatest in the world, is located along the Zambezi River and straddles the border between Zambia and Zimbabwe. The awe-inspiring nature of the waterfall is in part due to its enormous width—more than 5,500 feet (1,700 meters). The waters plunge as far as some 355 feet (108 meters) down and drop not into an open basin but into a dramatic-looking chasm. Victoria Falls is known for its veil of mist visible from miles away; the name given to the falls by an indigenous group is Mosi-oa-Tunya (“The Smoke That Thunders”). Victoria Falls and the adjoining areas were collectively designated a World Heritage site in 1989.

If an earthquake measures 1.5 on the Richter Scale, what is the intensity of this earthquake, relative to a 0-level earthquake? Round off your answer to the nearest integer.

Answers

Answer:

Intensity depends on the distance form the ground and source of energy.

Explanation:

Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale. This can be defied by the Richter scale formula of  R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)

The Mt. St Helens eruption in Washington state m 1980 measured 5 on the volcanic exclusivity index (VEI). Only 57 people died from the Mt. St Helens since most people were warned to evacuate the area prior to the event, Four years later, in 1985, del Ruiz in Colombia erupted. While only measuring 3 on the VEI, the eruption resulted in 25,000 deaths when unsuspecting residents of local towns were overrun by fast-moving lahars. Which of the following statements about volcano-related deaths best fit the information given in the paragraph?
a. Volcanic eruptions often kill thousands of people.
b. The death toll from volcanic eruptions do not always correlate to exclusivity, and can be affected by human actions before and after the eruption.
c. Most volcano-related deaths occur from lahars.
d. The death toll from a volcanic eruption is directly related to its volcanic exclusivity index (VEl).

Answers

Answer:

b. The death toll from volcanic eruptions do not always correlate to exclusivity, and can be affected by human actions before and after the eruption.

Explanation:

Many volcanic eruptions don't kill anyone. This is because most active volcanoes are well-known to local residents, who give them appropriate respect.

Lahars are deadly, but so are pyroclastic flows, and releases of ash and/or poison gases. The two deadliest eruptions in recorded history caused death by starvation and tsunami.

The point of the paragraph was that the VEI was not directly related to the number of deaths.
