what navigation equipment did europeans use in the 1400s​

Answers

Answer 1

Among the oldest and most basic tools was the lead line, used since antiquity to measure depth. This measurement could tell sailors how far they were from land. Another low-tech device, the ka-mal, was developed in Asia and the Middle East. It used a piece of wood marked for the position of Polaris at the latitude of various ports. By 1400, more sophisticated versions used a length of knotted string so the navigator could, by placing the string in his mouth, sight the horizon and the height of Polaris to judge latitude.

Timepieces also aided in navigation. In 1400, mariners still used hourglasses. These, in connection with careful observation of shorelines and accurate logbooks, helped navigators estimate location and predict arrival times.

Answer 2

The video, "Before Cook's Voyage", shows early navigation tools such as compass, astrolabe, octant and back staff, telescopes and the need to solve the longitude problem (time). ... Celestial navigation requires the sailor to use an instrument, like a sextant, to find the angle between a star/planet and the horizon.

what is the definition of correlation

Answers

Answer:

the state or relation of being correlated specifically: a relation existing between phenomena or things or between mathematical or statistical variables which tend to vary, be associated or occur together in a way not expected based on chance alone

or

a statistical measure that expresses the extent to which two variables are linearly related

choose the one you understand better

rate 5 stars and thank me :)

Explanation:

Final answer:

Correlation is an association indicating that when one variable changes, a second variable tends to change in a specific way, measured by the correlation coefficient (r), which ranges from -1 to +1.

Explanation:

The definition of correlation refers to the association between variables in which a change in one variable is associated with a change in another variable. When two variables are correlated, it indicates that as one variable changes, whether it increases or decreases, the other variable tends to change in a specific manner. This relationship can be quantified by a statistic known as the correlation coefficient, often represented by the letter r.

The coefficient of correlation, developed by Karl Pearson, ranges from -1 to +1. This measure gives the strength of the linear association between the independent variable (x) and the dependent variable (y). The sign (positive or negative) of the correlation coefficient indicates the direction of the relationship. A positive correlation means the variables move in the same direction, while a negative correlation indicates they move in opposite directions. Scatterplots can be used to provide a graphical view of the strength and direction of correlations.

Which of these situations BEST illustrates a case in which the due process of law is violated?

A) Police officers force a crime suspect from his home and imprison him.
B) Police officers force a crime suspect from his home and imprison him.
C) Two friends enter a legal dispute over a monetary loan that was not repaid.
D) A convicted drunk driver is charged with criminal negligence for her actions.

Answers

Answer:

The correct answer is  A; Police officers force a crime suspect from his home and imprison him.

Explanation:

It is deemed unconstitutional for a person to be imprisoned without conviction. The law states that a person is innocent until proven guilty.  

Answer:

The correct answer is A. A situation that best illustrates a case in which the due process of law is violated would be if police officers force a crime suspect from his home and imprison him.

Explanation:

Due process of law is a legal requirement that states that government must respect all legal rights possessed by a person, thus balancing the laws in force in an area and the rights of the people that lives in it. When the government is known to prosecute someone without following applicable law, it can be considered to violate due process accordingly, thus violating the rule of law.

 In this case, a forceful arrest without a proper search and arrest warrant motivated by the suspicion of a crime constitutes a clear violation of due process of law.

Why would the American people consider executive orders both good and bad for their government

Answers

Good: Things get done! Things getting done are good.

Bad: It circumvents the system. While things getting done are good, it is bad when the system doesn't work and a workaround is needed.

While executive orders can be a valuable tool for governance, providing agility and responsiveness, they also raise important questions about democratic processes, the separation of powers, and the potential for abuse of executive authority.

Good Aspects of Executive Orders:

1. Prompt Action: Executive orders allow the President to take immediate action in response to a crisis or urgent situation, which can be crucial when Congress is unable to act swiftly.

2. Policy Implementation: They enable the President to implement policies that align with their campaign promises and the platform on which they were elected, thereby fulfilling the will of the voters who supported them.

3. Flexibility: Executive orders provide flexibility in governance, allowing  the executive branch to adapt to changing circumstances without the need for new legislation.

4. Clarification of Laws: They can be used to clarify and refine how existing laws are to be executed, ensuring that the intent of the legislature is followed.

5. Advancing Social Issues: Historically, executive orders have been instrumental in advancing social issues, such as civil rights, when legislative progress was slow or stalled.

Bad Aspects of Executive Orders:

1. Lack of Congressional Oversight: Executive orders can bypass the legislative process, leading to concerns about the concentration of power in the executive branch and a lack of checks and balances.

2. Overreach: Critics argue that extensive use of executive orders can represent an overreach of presidential authority, particularly if they contradict existing laws or the Constitution.

3. Temporary Nature: Executive orders can be reversed by subsequent presidents, leading to instability in policy and governance, as new administrations may have different priorities.

4. Polarization: They can contribute to political polarization, especially if a president uses them to push through partisan agendas without bipartisan support.

5. Legality and Constitutionality Concerns: Some executive orders may face legal challenges if they are perceived to exceed the president's constitutional authority, leading to protracted legal battles and uncertainty.

How do you react to a change in the price of an item? How does this illustrate the concept of demand?

Answers

____________________________________________________

My reaction:

My reaction to a price change of an item would be different when the price increases or the price decreases. It really depends on the scenario and what's  happening to the price of the product.

If the price of an item changed by increasing the price, I would probably probably be mad because I wouldn't want to pay more for a product that use to be cheaper when I bought it before.

If the price of an item changed by decreasing the price, I would probably be happy because I am paying less for an item that use to cost more before, meaning that I am saving money because the price of the item is cheaper than before. This is probably a common reaction between many people due to the fact that the product got cheaper.

____________________________________________________

Definitions:

Demand:

Demand is the quantity of a product. For example, high demand means more quantities of the product, low demand is lower quantities of the product.

____________________________________________________

Why does this illustrate the concept of demand?

In this scenario, this illustrates the concept of demand because the price change of a product corresponds to the demand of the product.

When the price of a product decreases, that means that the products demand is low, meaning that they don't have to make as much of those products since customers don't really buy it, and they don't need to spend so much money on it, which is why it's getting cheaper. Companies wouldn't increase the price of a product if no one is buying it. Lowering the price for a low demand product will increase it's chance of being bought.

When the price of a product increases, that means that the products demand is high. This means that the company that is selling the product would increase the price since a lot of people are buying it, and increasing the price would get them more money. Even though the price increased, the demand for the product is still high, meaning that people would still buy the product even though the price increased.

It's very important for a company to check the demands of their products, so they know which ones they should make more of and which ones they should slow down on. High demand products = business, which they could rise the price so they could make more money off of people buying the product. Low demand products would lower the price so that people would keep buying the product.

Final answer:

Consumer reaction to price changes depends on the product's price elasticity of demand, which is calculated by dividing the percentage change in quantity demanded by the percentage change in price. Luxury goods often have higher elasticity, whereas necessities typically have inelastic demand. Understanding price elasticity is essential for both consumers and businesses.

Explanation:

When the price of an item changes, consumers will react in different ways based on the product's price elasticity of demand. If a product is considered a luxury and its price decreases, you might expect an increase in the quantity demanded because these goods often have a higher elasticity. On the other hand, goods that are necessities tend to have an inelastic demand, meaning that consumers will not significantly change the quantity they demand in response to a price change.

Calculating the price elasticity of demand involves dividing the percentage change in quantity demanded by the percentage change in price. The result is a coefficient that indicates whether the demand is inelastic, unit elastic, or elastic. These concepts are critical in understanding not only consumer behavior but also how businesses might strategically set prices.

Final answer:

The inspector couldn't impose the penalty because the Supreme Court decision in United States v. E. C. Knight established that manufacturing wasn't subject to federal regulation under the commerce clause, showing the manufacturing sector's significant influence and importance.

Explanation:

Reason for Inspector's Inability to Impose Penalty

The inspector was unable to impose the penalty he asked for because of decisions such as in United States v. E. C. Knight, where the Supreme Court ruled that manufacturing was not subject to federal regulation under the Sherman Act. This legal precedent suggested that the factory owners and manufacturing industry had significant leverage and importance, which protected them from certain regulatory attempts by the government.

The Role of Factory Owners and Importance of Manufacturing

Early factory owners and managers pursued profit maximization by simplifying the manufacturing process to be executed by cheap, unskilled labor. This led to the exploitation of workers, including children. The court decision, by distinguishing between commerce and production, suggested that manufacturing was crucial to the economy to the extent that the court was hesitant to allow federal interference, consequently emphasizing the importance of the manufacturing sector and its influence over legal decisions.
