The number of subsets is an illustration of combination
The set with 14 elements have 8192 subsets with an odd number of elements
How to determine the number of subsets?
The number of elements in the set is:
n = 14
The odd numbers less than or equal to 14 are:
Odd = 1, 3, 5, 7, 9, 11, 13
The number of subsets is then calculated as:
Subsets = 14C1 + 14C3 + 14C5 + 14C7 + 14C9 + 14C11 + 14C13
Evaluate the combination expressions
Subsets = 14 + 364 + 2002 + 3432 + 2002 + 364 + 14
Evaluate the sum
Subsets = 8192
Hence, the set with 14 elements have 8192 subsets with an odd number of elements

How vocation stress may negatively affect your family
Explanation:
Vocational stress refers to the stress caused because of one’s professional settings. It can be caused because of a number of reasons, like the fear of losing one’s job, working overtime, not getting credit for one’s efforts, being pushed to meet unrealistic targets, being blamed unfairly, not getting along with the boss or colleagues, or being forced to compromise with one’s honesty. In any case, vocational stress causes feelings of fear and anxiety, which greatly affects family life.
A high degree of stress or anxiety makes one irritable and impatient. The person becomes unpredictable and easily loses his/her temper with family members. Tantrums become common and the rest of the family start avoiding the individual. A disconnect starts setting in, pushing him/her further into depression. This leads to a lack of confidence and eventually with growing frequency of arguments, family life does not remain peaceful.

Answer:
Displacement is the word we use for the distance covered so in this case when a car travels 20 meters east in 1 second, at the end of that 1-second interval a car travels a distance of 20 meters.
And the distance covered is the displacement, so it means that displacement of the car after 1 second is 20 meters east.

One of the most important characteristics of the water molecule is its _____, which allows it to surround and attract both positive and negative ions.
Answer:
Polarity
Explanation:
Covalent bonds may be either polar or nonpolar. Polar molecules, such as water, are asymmetric molecules that have unbalanced electronegativity, leading to slight charges on the atoms within the molecule.
Water's polarity
The chemical equation for water is [tex]H_20[/tex]. In this molecule, oxygen has 2 unbonded electron pairs. This causes the molecule to have a bent geometry. Bent molecules are always polar due to the dipoles formed by the unshared electron pairs. These dipoles create a slight negative charge on the oxygen atom and a slight positive on the hydrogen atoms.
Intermolecular Forces
Due to the slight charges of a water molecule, the oxygen molecules attract positive ions, and the hydrogen atmos attract negative ions. This interaction is known as an ion-dipole intermolecular force (IMF).
Answer:
Polarity
Explanation:
Polarity in a substance or molecules arises when the two combining atoms have different electronegativities. As more electronegative atoms will attract the electrons from electropositive atoms toward itself.
Due to this, there will be development of partial positive charge on electropositive atoms and a partial negative charge on the electronegative atoms.
For example, in water (H₂O) due to the difference in electronegativities of the hydrogen and oxygen atoms, there is a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
Due to these charges it is able to attract ions of opposite charges that are surrounding.
Thus, we can conclude that one of the most important characteristics of the water molecule is it's polarity, which allows it to surround and attract both positive and negative ions.
One beaker contains pure water and the other beaker contains pure methanol at the same temperature. Which liquid has the higher surface tension and viscosity?
The water has a higher viscosity and surface tension compared to the methanol.
What is Surface Tension?Surface tension can be defined as the force that acts on the surface of a liquid to give it am elastic skin that is stretched.

You want to measure the height of an antenna on the top of a 125 foot building
In a 125-ft tall building, if you measure the angle of elevation to the top of the building to be 68° and the angle of elevation to the top of the antenna to be 71°, the height of the antenna is 21.7 ft.
What is the tangent of an angle?In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Step 1: Calculate the distance to the builiding (x).We will use the tangent of 68°, being the height of the building (h1 = 125 ft) the opposite side.
tan 68° = 125 ft / x
x = 50.5 ft
Step 2: Calculate the height of the building and the antenna (h2).We will use the tangent of 71°, being the distance to the building (x = 50.5 ft) the adjacent side.
tan 71° = h2 / 50.5 ft
h2 = 146.7 ft
Step 3: Calculate the height of the antenna.h2 - h1 = 146.7 ft - 125 ft = 21.7 ft
In a 125-ft tall building, if you measure the angle of elevation to the top of the building to be 68° and the angle of elevation to the top of the antenna to be 71°, the height of the antenna is 21.7 ft.

Harmony is currently producing 100 units of a necessary component part by incurring p60,000 in direct materials, p12,500 in direct labor, p22,500 in variable overhead, and p15,000 in fixed overhead. Harmony can purchase the component externally for p95,000 and only p2,500 of fixed manufacturing costs cannot be avoided (the rest are avoidable). How much savings will harmony realize in buying instead of making the component?
By taking the difference between the two costs, we conclude that buying instead of making the component, she saves $12,500
How much will she save?If she makes the components, the cost is:
$60,000 + $12,500 + $22,500 + $15,000 = $110,000
On the other hand, if she buys the components, the cost will be:
$95,000 + $2,500 = $97,500
To find how much did she saves, we need to find the difference between the two costs. That is just:
$110,000 - $97,500 = $12,500
This means that by buying instead of making the component, she saves $12,500

What is a difference between an authoritarian government and a democratic government brainly
Answer:
The difference between an authoritarian government and a democratic government is that the authoritarian government has complete power/ownership over the country and everyone within the country, while a democratic government the government has very limited power divided in three branches while the citizens choose who gets elected to be in high power on their behalf.
Explanation:
Authoritarian government is on the basis of authority. The leaders of the government control every central part of the government and make changes to the country without its citizens consent or say. Authoritarian government is a very risky/evil form of government because it gives the leaders of the government complete control over every aspect of a person's life that's including entertainment, (by restricting their citizens from different forms of entertainment such as video games) social, (controlling their beliefs and what they feel is wrong or right) and financial which is by limiting how much of THEIR OWN money they can have/spend.
A common example of an authoritarian government would be Russia. Russian citizens do not have a say in what the country does and that is including war. Which is why will see many anti-war protests from Russian citizens during these times, you will also see them getting arrested for these protests. Entertainment, social, and financial control over a group of people's lives is authoritarian.
Democratic government is basically where the citizens of the country have a complete say in who becomes an elected official for their country. Common example of a democratic government is America. People in America choose who makes the decisions on behalf of them in government and Americans even have legislatures in place to make sure the government doesn't get too much power like separation of powers or checks and balances which divides the power between the three branches of government and the citizens are the ones who vote in the elected officials who will run these three branches of government.
They're many differences between an authoritarian government and a democratic government, so I will sum the complete different between the two in one statement. "The difference between an authoritarian government and a democratic government is that the authoritarian government has complete power/ownership over the country and everyone within the country, while a democratic government the government has very limited power divided in three branches while the citizens choose who gets elected to be in high power on their behalf."
