(TRUE OR FALSE)

Answers

Answer 1

The given statement "Two of the major challenges business users face when using big data are finding the information they need to make decisions and knowing that the data they have is valid." is true because if the data is not clear and accurate, it will corrupt the process of decision making.

Big data basically refers to the data sets which are too large or we can say too complex to be dealt with the help of traditional data-processing applications. Data which have many entries happen to offer a greater statistical power whereas the data which has a higher complexity basically leads to a higher amount of false discovery rate.

While using big data, the two crucial challenges which the businesses face are the finding of information which they need and also knowing if the data that they have is valid.

briefly describe the tools used by a central bank to affect the money supply and identify which is the most powerful and commonly used method and which is the weakest method.

Answers

Central banks use open market operations, reserve requirements, and discount rates to influence the money supply, with open market operations being the most powerful.

Central banks employ several tools to control the money supply within an economy. One of the primary methods is through open market operations, which involves the buying or selling of government securities in the open market. By purchasing government securities, the central bank injects money into the economy, increasing the money supply. Conversely, selling government securities reduces the money supply. Open market operations are considered the most powerful tool as they directly impact the liquidity and overall money supply in the economy. Central banks frequently utilize this tool to regulate interest rates and stabilize the financial system.

Another tool used by central banks is adjusting reserve requirements. Banks are required to hold a certain percentage of their deposits as reserves. By raising or lowering the reserve requirement, the central bank can influence the amount of money banks can lend out. Increasing reserve requirements reduces the lending capacity of banks, thereby decreasing the money supply, while decreasing reserve requirements has the opposite effect. However, reserve requirements are often seen as a weaker tool compared to open market operations, as changes in reserve requirements can have a more gradual and delayed impact on the money supply.

An investment pays you $20,000 at the end of this year and $ 10,000 at the end of each of the four following years. What is the present value (PV) of this investment, given that the interest rate is 5% per year?

Answers

The present value of the investment is approximately $52,837.72.

To calculate the present value (PV) of the investment, we need to discount the future cash flows to their present value using the given interest rate.

The present value of each cash flow can be calculated using the formula:

PV = CF / \((1 + r)^{n}\)

Where PV is the present value, CF is the cash flow, r is the interest rate, and n is the number of periods.

In this case, the cash flows are $20,000 at the end of the first year and $10,000 at the end of each subsequent year for four years. The interest rate is 5% per year.

Calculating the present value of each cash flow:

PV1 = $20,000 / \((1 + 0.05)^1\)

PV2 = $10,000 / \((1 + 0.05)^2\)

PV3 = $10,000 / \((1 + 0.05)^3\)

PV4 = $10,000 / \((1 + 0.05)^4\)

PV5 = $10,000 / \((1 + 0.05)^5\)

Adding up the present values:

PV = PV1 + PV2 + PV3 + PV4 + PV5

Calculating each PV:

PV1 = $20,000 / \((1.05)^1\) = $20,000 / 1.05 = $19,047.62

PV2 = $10,000 / \((1.05)^2\) = $10,000 / 1.1025 = $9,070.29

PV3 = $10,000 / \((1.05)^2\) = $10,000 / 1.1576 = $8,650.97

PV4 = $10,000 / \((1.05)^4\) = $10,000 / 1.2155 = $8,231.85

PV5 = $10,000 / \((1.05)^5\) = $10,000 / 1.2763 = $7,836.99

Adding up the PVs:

PV = $19,047.62 + $9,070.29 + $8,650.97 + $8,231.85 + $7,836.99 = $52,837.72

Therefore, the present value of the investment is approximately $52,837.72.

Explanation:

While drilling metal, Ben poured oil over the area, and Ben was trying to reduce kinetic friction. Therefore option B is correct.

What is Kinetic friction?

The kinetic friction force, also known as sliding friction, only affects moving objects (thus the term "kinetic"). Pushing a box across floorboards is an example of this force opposing sliding motion. This sort of friction has a particular coefficient of friction (such as rolling friction).

Static friction, which is the resistance to motion brought on by the friction between a motionless item and a surface, is the other main type of friction that occurs between solids. The force of friction is weaker for items that are already moving because the coefficient of static friction is often greater than the coefficient of kinetic friction.

how do you calculate a total including sales tax?

Answers

Answer:

  Add the tax to the subtotal to calculate the total amount

Explanation:

Add the prices of items purchased to obtain a subtotal.

Multiply that subtotal by the tax rate to determine the tax.

Add the tax to the subtotal to calculate the total amount.

__

Example

Purchases total 6.95. The tax rate is 8.2%.

The tax due is ...

  0.082 × 6.95 = 0.5699       rounds to 0.57.

The total amount due is ...

  6.95 +0.57 = 7.52

_____

Comment on percent

The % (percent symbol) is a fancy shorthand way to write /100. That is, a tax rate of 8.2% means you multiply the pre-tax amount by 8.2/100 = 0.082.

To calculate the total amount including sales tax, follow these steps:

The Steps to follow

Determine the sales tax rate (expressed as a percentage).

Multiply the sales tax rate by the original price to find the tax amount.

Add the tax amount to the original price to get the total amount, including sales tax.

Formula: Total = Original Price + (Original Price * Sales Tax Rate)

Example: If the original price is $50 and the sales tax rate is 10%, the total amount would be $55.

Remember, the sales tax rate may vary depending on the location and the type of product or service being taxed.

Answers

Therefore, the correct option is D, the appropriate monetary policy in the event of a recessionary gap would be to engage in an open market purchase of U.S. government securities.

A recessionary gap happens when the economy is not creating enough jobs, and unemployment is high, which leads to low consumer spending. In macroeconomics, a recessionary gap is referred to as a gap that occurs when actual gross domestic product (GDP) is less than potential GDP, meaning the economy is underutilizing its resources such as capital and labor to produce goods and services.

Therefore, the government uses various monetary policies to stimulate the economy and prevent the recession. One of the monetary policy, in this case, is to engage in an open market purchase of U.S. government securities. The Federal Reserve's policy of buying U.S. Treasuries in the open market is an example of an open market purchase. When the central bank purchases these securities, it increases the money supply in the economy.

A country experiences a contractionary gap, also known as a recessionary gap, when its real GDP is lower than its GDP at full employment. Real wages return to equilibrium, closing recessionary gaps when demand and supply of labor are equal.

d) Given the EOQ, what is the total annual cost of managing (ordering and holding) the inventory? $_______ (round your response to two decimal places)

Answers

The total annual cost of managing the inventory is $94.44 (rounded to two decimal places).

To calculate the total annual cost of managing the inventory, we need to use the Economic Order Quantity (EOQ) formula:

EOQ = sqrt((2 * annual demand * order cost) / holding cost per bracket per year)

EOQ = sqrt((2 * 2540 * 18) / 1.30) = 140.72

Now that we have calculated the EOQ, we can use it to calculate the total annual cost:

Total annual cost = (annual demand / EOQ) * order cost + (EOQ / 2) * holding cost per bracket per year

Total annual cost = (2540 / 140.72) * 18 + (140.72 / 2) * 1.30 = $94.44

Therefore, the total annual cost of managing the inventory is $94.44 (rounded to two decimal places).

Bradley has just graduated with an MA in Advertising at a prestigious university and has been hired as an account planner at a large advertising agency. In talking with some of his new colleagues, he heard of a practice that concerned him. Several account planners had an assignment to do some research on the competitor firms of one of the agency's major clients. The assignment proved to be unusually tough. The account planners decided to conduct a telephone survey, but when they identified themselves as agency employees, important sources refused to participate in the study. The deadline was quickly caseing, and the planners desperately needed the information. Then one of the planners, who had recently graduated from a local university, suggested that they identify themselves as "university students who were doing research for a class project." This case worked like a charm. Everyone was willing to help the "students" out, and the agency secured the important competitive information that it needed. The research was finished on time and within the budgeted cost. The client was immensely pleased. Bradley is concerned about the manner in which the planners deceived the respondents, but he thinks that this might just be part of doing business. In addition, as the newest planner, he does not want to rock the boat, and he very much wants to win the respect and acceptance of his new co-workers. QUESTIONS: 1. What, if anything, is ethically problematic about this case? 2. Who, if anyone, is potentially affected by this approach and how? 3. What ethical guidelines apply in this case? 4. What options are available to Bradley?

Answers

Account planners deceived respondents by identifying as students to gather competitive information for their client.

1. There are several ethical issues with this case. First, the account planners deceived the respondents by identifying themselves as students when they were actually working for an advertising agency.  Second, the account planners used the information they gathered from the respondents for commercial purposes, which is not what the respondents were expecting when they agreed to participate in the survey.

2. The respondents are potentially affected by this approach in several ways. First, they may feel misled or deceived by the account planners' misrepresentation.  Second, the respondents may not have given their informed consent to have their information used for commercial purposes. This could violate their privacy rights. Third, the respondents may not have been aware that the information they provided could be used to harm their competitors.

3. Several ethical guidelines apply to this case, including the following:

The American Marketing Association's (AMA) Code of Ethics: The AMA Code of Ethics prohibits deceptive research practices, such as misrepresenting the identity of the researcher or the purpose of the research.

The Society for Consumer Psychology's (SCP) Code of Ethics: The SCP Code of Ethics also prohibits deceptive research practices, and it specifically requires researchers to obtain informed consent from participants before collecting any personal information from them.

The Federal Trade Commission's (FTC) Guidelines for Consumer Research: The FTC Guidelines for Consumer Research prohibit deceptive research practices, and they also require researchers to disclose the commercial purpose of the research to participants.

4. Bradley has several options available to him. He could:

Speak to his colleagues about his concerns and try to persuade them to adopt a more ethical approach to research.

Refuse to participate in the research if he believes that it is unethical.

He could also choose to do nothing, but this would mean that he would be complicit in the unethical behavior of his colleagues.

The average height of your sample is 69 inches, while the standard deviation of the heights in your sample is 5 inches. The standard error of your estimate of the average height in the city is 0.5 " Points: 1/1 Explanation: Close Explanation Statisticians use various methods of measuring the uncertainty and reliability of parameter estimates. One of these measures is the standard error of a sample mean, which is computed as the standard deviation of the sample divided by the square root of the sample size. In this case, since the standard deviation of the sample is 5 inches and the sample size is 100, the standard error of your sample mean is b =0.5. 5 100 A useful rule of thumb is that the true value of the parameter lies within the range of two standard errors on either side of the parameter estimate, 95 percent of the time. In this case, this means that the true average height of people in the city lies between 69 - (2 x 0.5) and 69+(2 x 0.5) inches, with 95 percent certainty. STEP: 2 of 2 The measure of standard error can also be applied to the parameter estimates resulting from linear regressions. For example, consider the following linear regression equation that describes the relationship between education and wage: WAGE} = Bo + B, EDUC; + Ei where WAGE; is the hourly wage of person i i.e., any specific person) and EDUC, is the number of years of education for that same person. The residual &; encompasses other factors that influence wage, and is assumed to be uncorrelated with education and have a mean of zero. Suppose that after collecting a cross-sectional data set, you run an OLS regression to obtain the following parameter estimates: WAGE; = -11.1+ 6.4 EDUC; and . As the number of observations If the standard error of the estimate of B1 is 1.19, then the true value of B, lies between in a data set grows, you would expect this range to in size. Suppose that after collecting a cross-sectional data set, you run an OLS regression to obt pllowing 5.805 4.02 WAGE; = -11.1+6.4 EDUC; 5.21 4.615 and If the standard error of the estimate of B1 is 1.19, then the true value of B1 lies between in a data set grows, you would expect this range to in size and . As the number of observations lue of B1 lies between in size. 8.78 6.995 Grade Final Step (to complete this step and unlock the next step) 7.59 If the standard error of the estimate of B1 is 1.19, then the true value of Bi lie in a data set grows, you would expect this range to in size. increase TOTAL SCORE: 1/2 decrease The wind direction at Phoenix, in south-central Arizona, was generally from the ______.
