A.
It is equal to about 0.5 times the mean absolute deviation of either data set.
B.
It is equal to about 1 times the mean absolute deviation of either data set.
C.
It is equal to about 1.5 times the mean absolute deviation of either data set.
D.
It is equal to about 2 times the mean absolute deviation of either data set.

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

what are the impacts of land relief on agriculture?​

Answers

Topography relates to how difficult it is to till land, soil erosion and poor transportation networks and facilities. Agriculture can be mechanized depending on the topography of land to be used. It's impossible to use farm machinery on sloppy land or rough, hilly slopes. Climate, land relief, soil and vegetation are the main factors which influence agricultural activity. The growth of plants depends on the temperature and humidity of the land and the amount of light it receives. The relief of the land determines the type of activity that takes place on the land. In highlands such as hills mountains and plateaus where the slope of the land is generally steep the land is used for grazing sheep and goats. ... Terrace farming is also undertaken on hilly slopes to grow crop such as rice barley and tea.

Regional Geography lays emphasis on the distinctiveness of a particular place and the characteristics or activities that make up that location. With specific examples from Ghana and knowledge acquired in the Regional Geography of Ghana course so far, discuss the above statement.


Answers

Answer:

Ghana is a West African country in Africa, along the Gulf of Guinea, just a few degrees north of the equator.

Ghana encompasses plains, low hills, rivers, Lake Volta, the world's largest artificial lake, Dodi Island and Bobowasi Island on the south Atlantic Ocean coast of Ghana.[1] Ghana can be divided into four different geographical ecoregions. The coastline is mostly a low, sandy shore backed by plains and scrub and intersected by several rivers and streams. The northern part of Ghana features high plains.[2] South-west and south-central Ghana is made up of a forested plateau region consisting of the Ashanti uplands and the Kwahu Plateau. The hilly Akwapim-Togo ranges are found along Ghana's eastern international border.[3]

The Volta Basin takes up most of south-central Ghana and Ghana's highest point is Mount Afadja which is 885 m (2,904 ft) and is found in the Akwapim-Togo ranges.[4][5] The climate is tropical and the eastern coastal belt is warm and comparatively dry, the south-west corner of Ghana is hot and humid, and the north of Ghana is warm and wet.[2] Lake Volta, the world's largest artificial lake, extends through small portions of south-eastern Ghana and many tributary rivers such as the Oti and Afram rivers flow into it.[6]

Explanation:

The northernmost part of Ghana is Pulmakong and the southernmost part of Ghana is Cape three points near Axim. Ghana lies between latitudes 4° and 12°N.[7] South Ghana contains evergreen and semi-deciduous forests consisting of trees such as mahogany, odum, ebony and it also contains much of Ghana's oil palms and mangroves with shea trees, baobabs and acacias found in the northern part of Ghana.[7]

The particular name of an igneous rocks consisting of minerals is best determined using the chart in the lab book and noting:____.

(c) the relative color (light, intermediate, or dark) and the relative size of the minerals (phaneritic/aphanitic).
(d) whether the minerals present are metallic or non-metallic and then determining the streak on each mineral present.

Answers

Answer:

C, the relative color

Explanation:

Color indicates the composition of a rock or mineral.  A felsic composition is indicated by light colors such as white or pink.  Intermediate rocks or minerals have a medium color such as gray or an equal part of dark and light colored minerals . Mafic or ultramafic rocks or minerals are dark colored such as black or brown however they might also contain light colored minerals within them.

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.

Answers

Answer:

Aloft high pressure develops in cold air regions while low pressure develops in warm air regions

Explanation:

A thermally-driven circulation, or thermals are the movement of warm air that move to a higher level due to the buoyancy forces acting on them. That is due to the difference in densities between the warmed and cool air

Given that pressure = Density, ρ × Gravity, g × Height, h, we have that decrease in pressure (low pressure) is due to low density, therefore, the warm air having low pressure, moves upwards, due to their low density

Therefore, the best option is aloft, (as we move higher), high pressure develops in cold air regions while low pressure develops in warm air regions

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.
