Prove that root 2 as irrational number​

Answers

Answer 1
To prove: √2 is an irrational number. Proof: Let us assume that √2 is a rational number. So it can be expressed in the form p/q where p, q are co-prime integers and q≠0. √2 = p/q. ...
Solving. √2 = p/q. On squaring both the side we get, =>2 = (p/q)2

Answers

Tropical. In this hot and humid zone, the average temperatures are greater than 64°F (18°C) year-round and there is more than 59 inches of precipitation each year.

Dry. These climate zones are so dry because moisture is rapidly evaporated from the air and there is very little precipitation.

Temperate. In this zone, there are typically warm and humid summers with thunderstorms and mild winters.

Continental. These regions have warm to cool summers and very cold winters. In the winter, this zone can experience snowstorms, strong winds, and very cold temperatures—sometimes falling below -22°F (-30°C)!

Polar. In the polar climate zones, it’s extremely cold. Even in summer, the temperatures here never go higher than 50°F (10°C)!

How Is Wasting Water Bad for the Environment?

Answers

Answer:

Kindly check explanation

Explanation:

Even though the water revolves around a cycle such that used water can still be reused, water flowing through the surface may flow into water bodies,such as rivers, some percolate down the surface down to water aquifers, while some evaporate to the atmosphere to form clouds. However, water wasting could occur when, usable amount of water undergoes this cycle process without it being useful for human use. This could occur during pumping of water, when reservoirs are over filled, this overfilled water which travel as run off is just more than the amount needed by some to perform their daily chores of washing, drinking and watering their plants. Therfore, wasting of water could be the lack of adequate or appropriate channeling, hence, leading to deficiency in some part of the environment and excessive in others. Areas wit deficiency will suffer from poor growth of plant, residents will also suffer from dehydration and so on.

The amount of accessible water within the environment is diminished.

In the Northern and Southern Hemispheres, the Coriolis effect changes the direction of wind circulation, affecting the weather. Identify the arrows of circulation that most influence the weather in the United States.

Answers

Answer:

The arrows of circulation that most affect the US climate are the arrows on the left side of the northern hemsphere. In the attached image below you can see these cetas highlighted by a pink square.

Explanation:

As shown in the question above, the Coriolis Effect is an atmospheric phenomenon that modifies the direction of wind circulation in the terrestrial globe, completely modifying the climate of the regions. This phenomenon occurs due to the rotation of the earth on its own axis, which has the ability to create a reference system for this rotation.

The Coriolis effect has the ability to change the direction of winds within the hemispheres. This causes winds in the southern hemisphere to turn clockwise while winds in the northern hemisphere turn counterclockwise.

The US is located in the northern hemisphere, on the left side of the globe, as shown in the attached figure below.

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.

Answers

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.

¿En qué medida la guerra civil de 1829 representa una lucha ideológica?

Answers

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.

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

Answers

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.

According to the bar chart in 2005, private houses in Singapore consumed 33 cubic meters
of water per month. On the contrary, 1 to 3 rooms high density building (HBD) flats
consumed less than the half amount. What do you think what was the reason behind this?

Answers

Answer:

Good city planning, money and population per capita.

Explanation:

I believe this has to do with better city planning and the other reasons above. This is because Singapore is one of many cities to implement a more greener approach to city building compared to other cities, especially when it comes to high density buildings. These buildings are better known for their efficient use of things like water and power, while most privately owned residences are not. Depending on who owns these homes, there are a few more reasons.

If you had the money, hiring maids is an option. It was found that house maids use up a lot of water for things like washing dishes and laundry. These use water and therefore increase the household use of it.

Another final reason is based on how many people live in these homes and flats. Depending on size, more or less persons could be living in these areas, decreasing the amount of water used.
