Which of the following changes to a database would most likely require the most rework to existing programs and queries?
a. adding a new field to a table
b. creating a new index
c. changing relationships between tables
d. adding a new view
Answers
Option (c), Changing relationships between tables is the change to a database that would most likely require the most rework to existing programs and queries.
Relationships between tables are the fundamental structure of a database. They determine how the data is organized and how it can be accessed. If the relationships between tables are changed, it can impact the entire database schema. This means that all the queries, programs, and reports that rely on those relationships would need to be updated to reflect the new structure.
Adding a new field to a table, creating a new index, and adding a new view are all relatively minor changes that would not require as much rework to existing programs and queries. Adding a new field to a table would require updating any programs that access that table, but it would not necessarily impact the overall structure of the database. Creating a new index would improve the performance of queries, but it would not fundamentally change the structure of the database. Adding a new view would create a new way to access the data, but it would not require changing the underlying structure of the database.

Benjamin sells newspapers. Benjammin says that a 5% increase in the price of newspapers will decrease the quantity demanded of newspapers by 10%. According to Benjamin, the demand for newspapers is and that price of elasticity of demand is
A elastic, 0.5.
B. inelastic, 2.
C cinelastic, 0.5.
D.elastic, 2.
Answers
According to Benjamin's statement, the demand for newspapers is elastic and the price elasticity of demand is 2.
According to Benjamin, a 5% increase in the price of newspapers will result in a 10% decrease in the quantity demanded of newspapers.
The price elasticity of demand measures how responsive the quantity demanded is to changes in price. If the percentage change in quantity demanded is greater than the percentage change in price, demand is considered elastic. On the other hand, if the percentage change in quantity demanded is less than the percentage change in price, demand is considered inelastic.
In this case, we have a 10% decrease in quantity demanded when the price increases by 5%. Since the percentage change in quantity demanded is greater than the percentage change in price, demand is elastic.
Now, let's calculate the price elasticity of demand. Elasticity is determined by dividing the percentage change in quantity demanded by the percentage change in price. In this case, the percentage change in quantity demanded is -10% (a decrease) and the percentage change in price is 5% (an increase).
Using the formula, elasticity = (% change in quantity demanded) / (% change in price), we get:
Elasticity = -10% / 5% = -2

( ) Structural models often derive from economic models but may also be obtained from informal reasoning.True
( ) Considering the model y=a+bx+u, consistent estimation of the parameter b relies on the following condition: C[x,u]=0.False
( ) Considering the model y=a+bx+u, a simultaneity problem arises when y and x are jointly determined.True
( ) In a multiple regression, a sufficient condition for consistently estimating the model parameters is the absence of exact linear relationships among the explanatory variables.True
The first statement is false. Structural models in economics are typically derived from economic theories and formal reasoning, rather than informal reasoning. These models aim to explain the relationships between various economic variables and the underlying economic mechanisms. They often involve the specification of mathematical equations that represent the behavior of economic agents and the interactions among them.
The second statement is true. In the model y = a + bx + u, consistent estimation of the parameter b relies on the condition C[x, u] = 0. This condition, known as the orthogonality condition, implies that the error term u is uncorrelated with the independent variable x. If this condition holds, it ensures that the estimated coefficient b is unbiased and consistent.
The third statement is true. A simultaneity problem arises when both the dependent variable y and one or more independent variables, such as x, are jointly determined. In this case, there is a feedback loop between y and x, making it difficult to disentangle the causal relationship between them. Simultaneity problems often require specialized estimation techniques, such as instrumental variables, to obtain consistent parameter estimates.
The fourth statement is also true. In multiple regression, a sufficient condition for consistently estimating the model parameters is the absence of exact linear relationships among the explanatory variables. This condition is known as multicollinearity. When exact linear relationships exist, it becomes impossible to uniquely determine the contribution of each variable, leading to estimation problems. To avoid multicollinearity, it is important to ensure that the explanatory variables are linearly independent or to employ techniques such as variable transformation or variable selection.

1) Inflation represents the rate of increase of the average price of goods. If inflation decreases from 10% to 5%, does the average price of goods decrease? Explain.
Answers
No, the average price of goods does not decrease when inflation decreases from 10% to 5%.
Inflation represents the rate of increase in the average price of goods and services over time. When inflation decreases, it means that the rate of price increase has slowed down, but it does not imply a decrease in the average price itself. Even with a lower inflation rate, prices can still continue to rise, albeit at a slower pace.
The percentage of inflation indicates the extent of price increase compared to the previous period. If the inflation rate decreases from 10% to 5%, it means that prices are still increasing but at a slower rate. For example, if an item was priced at $100 at the beginning of the year, with a 10% inflation rate, its price would increase to $110. However, with a 5% inflation rate, the price would increase to $105. While the rate of increase has decreased, the average price of goods has not decreased.
Therefore, it is important to differentiate between a decrease in the inflation rate (a decrease in the rate of price increase) and an actual decrease in the average price of goods, which would indicate deflation.

Given the following information what must be the risk-free rate
in this economy?
Expected return of asset = .15
Beta of asset = 1.73
Expected return of market = 0.1
Answer as a percentage to two decim
Answers
To determine the risk-free rate in this economy, we can use the Capital Asset Pricing Model (CAPM) equation, which relates the expected return of an asset to its beta and the expected return of the market. In this case, the expected return of the asset is 0.15, the beta is 1.73, and the expected return of the market is 0.1.
The CAPM equation is as follows:
Expected Return of Asset = Risk-Free Rate + Beta × (Expected Return of Market - Risk-Free Rate)
By rearranging the equation and solving for the risk-free rate, we can find:
Risk-Free Rate = (Expected Return of Asset - Beta × Expected Return of Market) / (1 - Beta)
Substituting the given values into the equation, we can calculate the risk-free rate as a percentage to two decimal places.

b) list 3 ways in which cost are analyzed according to function
Answers
Cost analysis according to function involves examining costs based on their specific functions within an organization. Here are three ways in which costs can be analyzed according to function:
1. Direct costs: Direct costs are expenses that can be directly traced to a specific function or activity. These costs are directly associated with producing a particular product or delivering a specific service. Analyzing costs by function allows businesses to identify and allocate direct costs accurately. For example, in a manufacturing company, direct costs for a specific product may include raw materials, labor costs directly involved in production, and equipment maintenance costs specific to that product line.
2. Indirect costs: Indirect costs are expenses that are not directly tied to a specific function or activity but still contribute to the overall operation of the organization. These costs are shared among multiple functions or activities within the business. Analyzing costs by function helps in assigning a portion of indirect costs to different functions based on their usage or allocation criteria. Examples of indirect costs include rent, utilities, administrative salaries, and general supplies.
3. Overhead costs: Overhead costs encompass all the expenses that are necessary for running the business but cannot be directly assigned to a specific function or activity. These costs are incurred to support the overall operations of the organization. Analyzing costs by function helps in understanding the portion of overhead costs allocated to different functions based on their utilization or predetermined allocation methods. Overhead costs may include facility maintenance, depreciation of shared assets, insurance, and other general administrative expenses.
By analyzing costs according to function, businesses can gain insights into the specific expenses associated with each function or activity. This information allows for better cost management, budgeting, and decision-making within the organization.

Michael perez deposited a total of $2000 with two savings institutions. one pays interest at a rate of 6%/year, whereas the other pays interest at a rate of 7%/year. if michael earned a total of $136 in interest during a single year, how much did he deposit in each institution? (let x and y denote the amount of money, in dollars, invested at 6% and 7%, respectively.)
Answers
Answer:
He invested $400 in the account with interest at 6%, while investing $1600 in the account with interest at 7%.
Explanation:
Given that Michael Perez deposited $ 2000 in two different accounts that granted an interest of 6% and 7% per year respectively, and that at the end of the year he obtained $ 136 in interest, to determine how much money he invested in each account it is necessary to perform the following calculation:
2000 = 100
136 = X
((136 x 100) / 2000) = X
13600/2000 = X
6.8 = X
Thus, the benefits obtained were 6.8% per year. Thus, the annual 7% of the account with the highest interest rate must subtract a 0.2% yield, with which Michael Perez invested 2/10 parts of his money in the account with interest at 6% and 8/10 in the account with interest at 7%.
Thus, in the account with interest at 6% he invested $ 400, while in the account with interest at 7% he invested $ 1600.
