¿Que entiendes por el desarrollo de un país ?
Answer:
En Español: Un país desarrollado, un país industrializado, tiene una economía madura y sofisticada, generalmente medida por el producto interno bruto (PIB) y / o el ingreso promedio por residente. Los países desarrollados tienen una infraestructura tecnológica avanzada y diversos sectores industriales y de servicios.
En English: A developed country, industrialized country, has a mature and sophisticated economy, usually measured by gross domestic product (GDP) and/or average income per resident. Developed countries have advanced technological infrastructure and have diverse industrial and service sectors.
ACT scores of a sample of UTC students are shown below. Student ACT Score A 22 B 28 C 20 D 21 E 28 F 23 G 26 a. Compute the mean and the variance. B. At 95% confidence, test to determine whether or not the variance of the ACT scores of the population of UTC students is significantly more than 8.
Solution :
a). Let x denotes ACT scores.
ACT scores = [tex]$\{ 22,28,20,21,28,23,26 \} ; n = 7$[/tex]
Mean, [tex]$(\overline x)=\frac{\sum x_i}{n}$[/tex]
[tex]$=\frac{168}{7}=24$[/tex]
Sample variance, [tex]$S^2=\frac{1}{n-1}\left(\sum x_i^2-n\overline x^2 \right)$[/tex]
[tex]$=\frac{1}{6}(4098-7 \times 24^2)$[/tex]
[tex]$=\frac{66}{6}$[/tex]
= 11
b). To test whether or not variance of ACT scores of population (say [tex]$\sigma^2$[/tex]) of the UTC students is significantly more than 8.
Consider the hypothesis :
[tex]$H_0: \sigma^2 \leq8$[/tex] vs [tex]$H_a: \sigma^2 >8$[/tex]
It is a right tailed test and α = 0.05
We have
[tex]$x^2_{n-1} = \frac{(n-1)s^2}{\sigma^2}$[/tex]
So test statics is
[tex]$x^2_7=\frac{(7-1)11}{8}$[/tex]
[tex]$=\frac{6 \times 11}{8}$[/tex]
= 8.25
Since our [tex]\text{test statistics is less than the critical value }[/tex]and it falls in a acceptation region, hence we fail to reject [tex]$H_0$[/tex] and conclude that variance is not greater than 8 significantly.
Describe four common characteristics developed countries have that give them an advantage over less-developed countries
Answer:
Developed countries have: High level of education, high employability rate, good infrastructure, good economy.
Explanation:
Developed countries are able to promote a very efficient standard of living for their citizens. This is due to the fact that they have many positive and efficient factors that are essential for a good quality of life and that promote the population more than the basics necessary to have a good life. This gives developed countries many advantages, as a population that has its needs met is capable of creating a stronger country. Among these advantages we can mention the high level of education, which allows for a high level of employability. This allows the country to have a population qualified to occupy all productive sectors, which provides a good economy and a good infrastructure that is capable of making the country functional, modern and dynamic.

give an account of the northern plains of India.
Answer:
The northern plain has been formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 Km long and 240 to 320 Km broad, is a densely populated physiographic division. With a rich soil cover combined with adequate water supply and favourable climate it is agriculturally a very productive part of India

¿En qué medida la guerra civil de 1829 representa una lucha ideológica?
Explanation:
Ideology is described as a collection of more or less structured concepts that identify a community, the goals sought on their behalf, and a course of action. Ideology is significant in two ways.
To begin with, it is useful for armed organisations in socialising soldiers with disparate objectives into a cohesive group, reducing principal-agent issues, and prioritising competing aims.
Some individuals of terrorist organizations act on moral convictions in ways that are not reducible to utilitarian reasoning, while others limit their strategic options for altruistic purposes, which are frequently normative considerations dictated by their ideology.

A camper takes a 100-gram piece of basalt rock from a campfire and places it in a cup holding 250 mililiters of water. The temperature of the rock is 300C and the temperature of the water is 20C. Air temperature is also 20C. In the process of heating the water with the basalt, the temperature of the basalt decreased more than the temperature of the water increased. This difference most likey occured because
Answer:
This difference most likely occurred because the specific heat of water is higher than that of basalt.
Explanation:
Basalt is a fine-grained, dark-colored igneous rock that is mostly made up of plagioclase and pyroxene minerals.
Water is a gaseous, liquid, or solid substance made up of the chemical elements hydrogen and oxygen, and it can exist in gaseous, liquid, and solid states.
Basalt can be used to heat water. But when the specific heat of water is higher than that of basalt, the temperature of the basalt will drop more than the temperature of the water will rise when the water is heated with the basalt.
Therefore, this difference most likely occurred because the specific heat of water is higher than that of basalt.
How is today’s weather related to your region climate
Explanation:
Weather describes the condition of the atmosphere. It might be sunny, hot, windy or cloudy, raining or snowing. Climate means the average weather conditions in a particular location based on the average weather experienced there over 30 years or more.
Weather depends on individual regional climate of area.
What is weather?The condition of the atmosphere, including its temperature, pressure, wind, humidity, precipitation, and cloud cover, is referred to as the weather. It is distinct from climate, which is the average of all weather events for a certain place over around 30 years.
On the other hand Climate, is totally different concept than weather, is the culmination of the weather patterns that have persisted across a region for an extended period of time.
The troposphere, the lowest part of the atmosphere that reaches 6-8 km (4-5 miles) at the poles and around 17 km (11 miles) at the equator, is where weather, as it is most frequently understood, takes place.
Therefore the degree of weather changeability varies greatly across the globe. It is particularly noticeable in the westerly wind's mid-latitude belts, where a typically continuous procession of moving high- and low-pressure centers altering the weather pattern.

In two or more sentences describe a procedure to increase the deposition of sediments at the mouth of a stream. Write your answer in your own words
Answer:
A sediment is any solid material that is moved and deposited in a new place and can be anything from rocks, or the remains of plants and animals.
Therefore, one way of increasing the deposits of sediments at the mouth of a stream is by reducing the amount of vegetation living near the stream.
By doing this, there is no more cover for the soil and this causes erosion to occur and then the stream carries the loose sediment.
