The average age of a breed of dog is 19. 5 years. If the distribution of their ages is normal and 20% of dogs are older than 22. 6 years, find the standard deviation
Answers
The standard deviation of the ages of this breed of dog is approximately 4.4 years.
To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).
Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:
z = (x - μ) / σ
Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:
σ = (x - μ) / z
Plugging in the values, we have:
σ = (22.6 - 19.5) / z
To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.
Substituting the values, we get:
σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4

Three reasons why lron cannot be used to make a replacement joint
Answers
Iron's susceptibility to corrosion, poor biocompatibility, and lack of mechanical strength make it unsuitable for use in replacement joints.
First of all, iron is very prone to corrosion when exposed to moisture and oxygen, which might eventually cause the joint to degrade. The joint may become unsuitable for long-term usage in the human body due to corrosion, which can degrade the joint's structural integrity and affect its functionality.
Second, iron has poor biocompatibility, which means that when it comes into touch with live tissues, it may result in unfavourable reactions and tissue responses. This may cause inflammation, immunological reactions, and even the immune system of the body rejecting the joint. Materials with strong biocompatibility are selected to guarantee a successful replacement joint to reduce the risk of problems and enhance patient outcomes.
The mechanical strength needed for a replacement joint is also lacking in iron. In order to endure the loads and forces that joints are subjected to during movement, a material must be strong enough. Iron is a powerful metal, but it might not have the best mechanical qualities, such as high tensile strength, fatigue resistance, and longevity, needed for a joint replacement.
These factors lead to the use of other materials, such as titanium alloys or cobalt-chromium alloys, which provide higher corrosion resistance, biocompatibility, and mechanical qualities suited for long-term usage in the human body.

5. Should the power plant be built here? Why or why not? Use facts from the assignment and your research to support your answer.
Answers
The Severn River is an ideal location for generating hydroelectricity due to its large volume of water, steep gradient, and steady flow.
Why is the Severn River a good location for generating hydroelectricity?The river is the longest in England, and its upper reaches are located in Wales, while its lower reaches are located in England. This unique geography allows for a large amount of water to flow through the river, providing a consistent and reliable source of energy. Additionally, the steep gradient of the river provides the potential for a high head of water, which increases the amount of energy that can be generated.Considering the advantages of the Severn River, it would be beneficial to build a power plant here. The hydroelectricity generated from this location would provide a clean and renewable source of energy for the local communities, and is a much more sustainable option than traditional energy sources such as fossil fuels. Additionally, the economic benefits of a power plant in the area would create jobs and provide a boost to the local economy.Nevertheless, the potential environmental impacts of building a power plant need to be considered. The construction of a power plant can cause disruption to the local environment, potentially affecting the river’s wildlife and habitat. Therefore, careful planning and implementation is essential to ensure that the environmental impacts are minimized. Additionally, the local communities should be consulted to ensure that the proposed power plant is beneficial to the area.To learn more about generating hydroelectricity refer to:

20ax - x= 5 in the equation above, a is a constant if the equation has no solution, what is the value of a ?
Answers
20ax - x = 5
x(20a - 1) = 5
For this equation to have no solution, the left side of the equation must be equal to 0 (since any number multiplied by 0 is 0). Therefore, we can set the expression inside the parentheses equal to 0 and solve for a:
20a - 1 = 0
20a = 1
a = 1/20
So if the equation 20ax - x = 5 has no solution, then the value of a is 1/20.

why is Pluto called a ,"dwarf planet" ?
Answers
Answer:
Pluto is called a dwarf planet because it does not meet the three criteria set forth by the International Astronomical Union (IAU) for a full-sized planet.
These criteria are:
It must be in orbit around the Sun.It must be massive enough for its self-gravity to overcome rigid body forces so that it assumes a hydro-static equilibrium (nearly round) shape.It has cleared the neighborhood around its orbit.Pluto meets the first two criteria, but it does not meet the third. The Kuiper Belt is home to many other objects that are similar in size to Pluto, and these objects share Pluto's orbit. This means that Pluto has not cleared its neighborhood of other objects, as a planet is supposed to do.
As a result of this, Pluto was reclassified as a dwarf planet in 2006. There are now five dwarf planets in our solar system: Pluto, Ceres, Eris, Makemake, and Haumea.
Answer and Explanation:
Pluto is called a "dwarf planet" because it does not meet the criteria to be classified as a full-fledged planet. In 2006, the International Astronomical Union (IAU) redefined the definition of a planet, which led to Pluto being reclassified as a dwarf planet. Here are the main reasons why:
1. Size: While Pluto is larger than some moons in our solar system, it is much smaller than the eight traditional planets like Earth, Jupiter, and Saturn. Its size is comparable to other objects in the Kuiper Belt, a region beyond Neptune where many icy bodies reside.
2. Orbit: Unlike the eight planets that have relatively clear paths around the Sun, Pluto has a more elongated and inclined orbit. This means it has a more irregular path and crosses the orbit of Neptune at certain points. This is different from the regular, more circular orbits of the traditional planets.
3. Neighborhood: Pluto is part of a region called the Kuiper Belt, which consists of numerous icy bodies and small objects. This region is distinct from the inner solar system where the eight traditional planets reside. The presence of many similar-sized objects in its vicinity further influenced the decision to reclassify Pluto.
By considering these factors, the IAU determined that Pluto did not meet the criteria to be classified as a planet. Instead, it was designated as a dwarf planet, a new category that acknowledges its unique characteristics and its place in the Kuiper Belt.
It's important to note that this reclassification sparked some debate and controversy among astronomers and the public. However, the IAU's decision to classify Pluto as a dwarf planet is the current scientific consensus.

Answers
The enthalpy change for combustion of 15.0 g of ethanol can be calculated using the equation δH = -555 kJ/mol x (moles of ethanol).
What is ethanol ?Ethanol, or ethyl alcohol, is a type of alcohol with the molecular formula C2H5OH. It is a colorless, volatile, flammable liquid that has a somewhat sweet odor and taste. Ethanol is a renewable fuel that can be derived from corn, wheat, barley, and other grains, as well as from cellulose-based feedstocks.
To calculate the moles of ethanol, 15.0 g (the mass given) must be divided by the molar mass of ethanol, 46.0 g/mol.
15.0 g/46.0 g/mol = 0.326 mol
Therefore, the enthalpy change for combustion of 15.0 g of ethanol is given by the equation:

Make a claim about two ways that fisheries are important and support your claims with specific evidence.
Answers
Fisheries are an essential part of many coastal communities and are vital to the economy, providing jobs and food for people around the world. Two ways that fisheries are important are as follows:
Economic Importance: Fisheries are a major source of income for many coastal communities around the world. According to the Food and Agriculture Organization of the United Nations (FAO), the global fisheries and aquaculture sector employed over 60 million people in 2018. In addition.
The sector contributed over $240 billion to the global economy in the same year. For many developing countries, fish exports are a significant source of foreign exchange earnings. In some areas, fishing is the only means of livelihood for small-scale fishermen and their families.
Nutritional Importance: Fisheries provide an important source of animal protein, omega-3 fatty acids, and other essential nutrients to millions of people around the world. Fish is a healthy food source, low in fat and high in protein, and essential vitamins and minerals such as vitamin D and calcium.
The FAO estimates that fish provides over 3 billion people with at least 15% of their average per capita intake of animal protein. Fish also plays an important role in food security, providing a source of nutrition for millions of people in developing countries who do not have access to other sources of protein.
In conclusion, fisheries are important for economic and nutritional reasons, providing employment opportunities.Therefore, it is crucial to ensure that fisheries are sustainably managed to protect both the environment and the livelihoods of the people who depend on them.
