One of the challenges for smaller businesses in using collaborative enterprise 2.0 tools is ________.
For this assignment you will write a crc integrity checking program will have two modes of operation. your program must implement the crc calculation method involving long division by a polynomial that we discussed in lecture. in "calculation" mode, the program will calculate the crc-12 value for a given input string. in "verification" mode, the program will interpret the last 3 hex characters of an input string as a crc-12 value, and it will then determine whether this is the correct crc-12 value for the input string without those 3 characters. in both modes, the program must report header information, intermediate results, and final results as described further below. the mode and the input string to process will be supplied to your program as command line arguments. the program will be graded according to the grading rubric that appears at the bottom of this assignment.
Of course, some of the recorded functions will very likely invoke others of these functions. It is decent practice to reuse components instead of writing the same block of code in multiple places. Many logical errors can be evaded by doing so, and if any corrections are needed, they can be done conveniently in just one place.
Keep in mind that the basic idea is to break down the overall task into small pieces that can be developed (and tested) separately so you can build your program incrementally.
Program Output
The program must present output consisting of header information, intermediate results, and final results, as described separately below. Sample outputs follow in the next section.
Header Information
The header information should be written on distinct lines as shown in the sample outputs that follow. The individual lines are:
1. The program must first write a string of 62 hyphens (dashes) to serve as a separator, and then, 2 lines below it, the string "CIS3360 Fall 2017 Integrity Checking Using CRC", and then on the next line the string "Author: " followed by your name (or names, if teaming) and a newline.
2. The program must then write the string "The input string (hex): ", followed by the string value of the second command line input argument
3. The program must then write the string "The input string (bin): ", followed by the binary value of the second command line input argument, and then a newline.
4. The program must then write the string "The polynomial that was used (binary bit string): ", followed by the 13-bit binary value of the polynomial given at the top of this assignment with spaces every 4 characters to improve readability.
5. The program must then write the string "Mode of operation: ", followed by either the word "calculation" or "verification", depending on the value of the first command line input argument
6. The content of this line depends on whether the mode is calculate or verify.
a. If in calculation mode, this line should read: "Number of zeroes that will be appended to the binary input: 12"
b. If in verification mode, this line should read: "The CRC observed at the end of the input: ", followed by the binary and hex values for the last 3 hex characters of the input string, as shown in the sample outputs that follow.
Intermediate Results
This section will begin with the string: "The binary string difference after each XOR step of the CRC calculation", followed by a newline.
Following the above statement, this section will show on separate lines the results of each XOR step as described above, with spaces every 4 characters as shown to improve readability.
Note that for calculation mode, you must pad the binary version of the input string with 12 zeroes before you start the division procedure, but for confirmation mode you have two choices. The first step is to remove the last three hex characters demonstrating the observed CRC, in which case you must then pad the rest with 12 zeroes like you were calculating the CRC. The second step is to leave the detected CRC attached to the rest of the input, in which case you should not add zeroes for padding. The difference between these two choices determines how you will interpret the result in the bottom row of the intermediate results output.

Nick inherited $150,000, which he immediately invested into a fund that will earn 10% per annum. if interest is compounded semi-annually, in five years the investment will grow to
First calculate the effective interest rate because the problem says that the interest is compounded semi-annually. The formula for effective interest rate is ieff= [(1+i/n)^n] – 1. The calculated effective interest rate is 10.25%. The value of the investment in 5 years could be calculated using the equation, FV= PV (1+i)^n. The value of the investment then would be $244,334.194.

A. the government often uses excise taxes, called "sin taxes," to manipulate consumption of cigarettes. draw and label the shift from a tax. identify the new price consumers pay, the price producers receive, the amount of tax revenue consumers pay, and the amount of tax revenue producers pay. lastly, explain why it is unlikely that this tax will significantly reduce cigarette consumption.
Excise taxes, often referred to as 'sin taxes', shift the supply curve upwards, leading to increased prices and decreased supply. While this should ideally reduce consumption, the addictive nature of products like cigarettes means demand is inelastic, or insensitive to price changes, resulting in unlikely significant changes to consumption patterns.
Explanation:The government utilizes excise taxes, often referred to as 'sin taxes', as a tool to influence market behavior. For products like cigarettes, this tax is levied in hopes to reduce consumption.
Illustrating this with a diagram, let's say the initial equilibrium price and quantity were P1 and Q1. Post tax, the supply curve shifts upwards by the amount of the tax, creating a new equilibrium at price P2 and quantity Q2. The difference between P2 and P1 shows the tax per unit which the consumer pays.
Producers receive price P3, lower than the previous price because of the tax amount taken by the government. The rectangle formed by the vertical distance between P2 and P3 and the horizontal distance at Q2 represents the tax revenue.
Theoretically, the tax should reduce consumption. But it's unlikely to significantly reduce cigarette consumption because of the addictive nature of smoking. Smokers will likely continue to purchase cigarettes despite the increased price, making cigarette demand inelastic.

Purchasing agents for merchandises are known as _____.
Purchasing agents responsible for acquiring merchandise for companies are typically referred to as buyers or purchasing managers. They play a critical role as intermediaries in the supply chain, influencing procurement strategies and pricing.
Purchasing agents for merchandises are commonly referred to as buyers or purchasing managers. These professionals are responsible for acquiring products that their company sells or uses in production. Their role is critical in the supply chain, functioning as intermediaries between suppliers and the companies they serve. In some scenarios, such as local farmers selling produce in markets, the producers also handle the sales directly to consumers. In a commercial context, purchasing agents must strategically source goods, negotiate contracts, and often manage inventory and supplier relations.
In historical contexts, such as in pre-communist China, commercial intermediaries were known as compradors. These individuals played a key role in managing a guild's foreign commercial relationships. Modern-day purchasing agents provide a similar link, ensuring that businesses efficiently procure goods and materials at fair and competitive prices. As a result, they can significantly influence the supply chain and overall business strategy of their organizations.
Wholesalers also play a pivotal role within the purchasing ecosystem by providing goods in bulk to retailers, who then sell these to the end consumer. The strategic purchasing decisions by these intermediaries can impact product availability, pricing, and market trends.

If you made a forecast for week 19, based on a 3 week weighted moving average, with oldest data to most recent data weighted 0.20, 0.30, and 0.50, respectively, how much would your forecast be different from the actual jobless claims?
The question is about calculating a weighted moving average forecast for week 19 jobless claims using given weights and then determining the difference between the forecast and the actual jobless claims. Actual data is necessary to compute the forecast and the difference.
The question pertains to the calculation of a weighted moving average for forecasting weekly jobless claims and then comparing the forecast to actual figures. To perform this forecast, one would typically take the actual jobless claims for the past three weeks and apply the weights of 0.20, 0.30, and 0.50, from the oldest to the most recent week, respectively. Without the actual numbers, we cannot compute the exact difference between the forecast and the real jobless claims, but generally, you would sum the products of each week's claim numbers and their corresponding weights to produce the forecast. The forecast's accuracy would then be evaluated by comparing it to the actual data for week 19. The difference between the forecast and the actual figures indicates the model's accuracy. Knowing how to interpret and manipulate graphical data, like the unemployment rates plotted monthly versus five-year averages as mentioned in the provided text, is crucial for understanding economic trends and making accurate forecasts.

The market equilibrium is not efficient when the consumption of a good creates external costs, which cause social costs to be:
Final answer:
The market equilibrium is not efficient when external costs are present, as they cause social costs to be greater than private costs, leading to market failure and overproduction of the good. A corrective tax can help bring production to a socially-optimum level by aligning private and social costs.
Explanation:
The market equilibrium is not efficient when the consumption of a good creates external costs. This occurs because such costs lead to a situation where social costs are greater than the private costs. Externalities create a divergence between private costs/benefits and social costs/benefits, leading to market failure. For example, if a steel producer pollutes the air, the buyer of the steel does not pay the full social cost, which includes environmental damage not accounted for in the steel's price. Consequently, the market ends up overproducing the good, resulting in a negative externality.
A corrective measure, such as a tax, can help align private costs with social costs by making it more expensive to produce goods or services that generate negative externalities, thereby incentivizing firms to reduce their production to a socially-optimum level. The optimal situation is a market where social benefit is equal to social cost, where marginal social benefit equals marginal social cost without any externalities influencing the outcome.
