The correlation between the number of hours Brad studies and the grades he gets is 0.8. Which phrase best describes the correlation between the number of hours Brad studies and the grades he achieves?

Answers

Answer 1

Answer: strong positive correlation

Explanation:

A positive correlation exists when the correlation coefficient that we've is greater than 0. This means that both variables that are given move in the same direction.

Since the correlation between the number of hours Brad studies and the grades he gets is 0.8, it means that there's a strong positive correlation due to the fact that the value is close to +1.

This means that the number of hours that Brad studied is a good predictor of

the grade that he gets in his examination but it's not perfect.

Ocean life appears to be affected by a relatively small number of variables such as temperature, density, available sunlight, available nutrients. If any one of these variables changes how do you think it might it impact the human food web?

Answers

Answer:

A change in one of these variables can cause a population decrease in some living being that has the ocean as its habitat. This decrease would affect the feeding of animals that consume this living being and this will disharmonize the entire food chain of consumers above this living being.

Explanation:

Although the ocean is affected by a relatively small number of variables. These variables are essential for the maintenance of living beings within the ocean. If one of these variables is modified, in the long term, many species of living beings can be negatively impacted in an intense way, even having their survival in danger and decreasing their population density. This would be very harmful to the harmony of food chains within the ocean. That's because, as you may already know, the food chain is a feeding sequence between living beings, where one species feeds on another, which shows how one species depends on the other to survive.

Thus, if there is a change in the variables that act on the ocean and this change causes the population reduction of a species of living being. The species of animals that feed on this living being will also be affected as they will not have enough food to sustain themselves. Isss will decrease the population density of this second species, affecting the species that will feed on it, and so on.

The half-life of Carbon-14 is 5, 730 years. you find a sample where 1.5625% of the original Carbon-14 still remains how old is that sample ?

Answers

Answer:

The sample is about 34380 years old.

Explanation:

The amount of Carbon-14 mass diminishes exponentially in time, whose model is described below:

[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (1)

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)

Where:

[tex]m_{o}[/tex] - Initial mass, in grams.

[tex]m(t)[/tex] - Current mass, in grams.

[tex]t[/tex] - Time, in years.

[tex]\tau[/tex] - Time constant, in years.

[tex]t_{1/2}[/tex] - Half-life, in years.

If we know that [tex]\frac{m(t)}{m_{o}} = \frac{1.5625}{100}[/tex] and [tex]t_{1/2} = 5730\,yr[/tex], then the age of the sample is:

[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]

[tex]\tau = 8266.643\,yr[/tex]

[tex]t = - \tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]

[tex]t = - (8266.643\,yr)\cdot \ln \frac{1.5625}{100}[/tex]

[tex]t \approx 34380.002\,yr[/tex]

The sample is about 34380 years old.

DAT Explain the significance of resouras. Suggest any three ways to conserve resources to achieve sustainable. development​

Answers

Answer:

Explanation:

Resources may be explained as a range of products, equipment, manpower and all other things an individual or organization has at its disposal in other to function prey and effectively.

Resources may also be natural which will include all resources borne out of nature such as air, sunlight, mineral resources and all resources devoid of human doing.

Resources are required on other to ensure that an organization functions well as it will be impossible to produce without the needed help (resources). Similarly, it will be impossible to survive without the availability of nature resources as they help us breath, make money, in food production and so on.

Resources conservation involves the effective and efficient use of resources. Conservation of resources can be enhanced in ways such as :

Embracing the use of renewables : The use of renewable energy sources provides a clean choice of energy which is obtained from nature's routine. The use of solar energy frolic the sun or wind powered energy obtained from natural breeze or wind.

Embrace Recycling : Recycling involves the reuse of already used materials as a form of raw material to make new products, these ensures that optimum use of the resources at our disposal is achieved while also ensuring that we have a cleaner environment.

Use of reusable goods or materials : The large influx of onr-tine use products such as disposables and certain plastic materials has contributed to large quantities of water materials on landfills, they adoption of reusable materials which can be used over certain period of time will go a long way in controlling these waste Influx.

The large-scale structures in this sedimentary environment are asymmetrical ripples (known as dunes at this size). Zoom in and out and examine the sedimentary environment. What type of sedimentary environment is this

Answers

Answer:

Eolian sedimentary environment

Explanation:

Winds can transport many different-sized particles of material from the ground through the process of erosion. These particles might travel many kilometers until they deposit somewhere. Regions with scarce vegetation have too much dust and grain-sized particles that move and crush each other, increasing erosion. This process is known as eolic erosion.

The most prominent accumulations of wind deposits are the dunes. However, there are other smaller accumulations such as the ripples and other larger ones called Draas. Their main differences are in addition to size, is the wavelength between them.

Dunes are winds deposits, formations that are, in general, typical of deserts. Dunes are orientated according to the direction and speed of winds, to the presence of loose material, and vegetation. Strong winds transport material until it collides with an object or obstacle where it is deposited, originating a new dune.

Dunes are very dynamic formations that are constantly being remodeled by the direction and strength of the winds. Dunes always have a soft slope and a sharp one. The soft slope is directed to the area or region where the wind is coming from and is the product of the wind erosion on the same dune. The opposite sharp slope is protected from the wind and is the deposition place, where the wind losses strength and the carrying material falls, depositing in this side of the dune.

Sinkiang is a desert in China. Placing yourself at 39 05 52.46N 84 30 56.16E lets you appreciate the duned shape of the ground. By zooming in and out, you can notice the soft and sharp slopes that are forming each of the dunes and the distance between them.

"Why Do We Study the Sun?" How does the Sun help to protect life on Earth?

Answers

Answer:

We study about the sun because  

The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.

Explanation:

How does the Sun help to protect life on Earth?

It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.

Why is erosion considered a slow process?

Answers

Explanation:

Weathering has deteriorated and broken up the sandstone, making it ready for destruction. Erosion occurs when ice, moisture, wind, or gravity take up and transport rocks and materials to a new location. They can't transport as much sediments if they slow down. Rock formations are where the sediment is dumped or deposited.
