A regional bank implemented an automated solution to streamline their operations for receiving and processing checks/cheques

Answers

A regional bank implemented an automated solution to streamline its operations for receiving and processing checks/cheques. They would like to further enhance the solution to recognize signs of potential check fraud and alert their security teams accordingly.

Which technology could be combined with the current solution to do this?​

Answer:

Machine learning

Explanation:

The technology that could be used in combining with the current solution to do this is known as MACHINE LEARNING

Given that Machine Learning is a form of Artificial Intelligence, which is designed to possess the ability to act or mimic human beings and their functional characteristics to solve human problems.

Hence, because the regional bank prefers to streamline their processes of receiving and carrying out checks/cheques while also enhancing the solution to recognize signs of potential check fraud, then the technology they could use is called MACHINE LEARNING.

This is because Machine Learning will operate like humans to solve human problems efficiently.

Write the field for the table "BOOK" with its field type and also write the primary key for the table.

Answers

Answer:

Fields are the components that provide structure for a table. Fields in a table store the same category of data in the same data type. For example, if you have a NAME field in a table of customers, the entries for this field are all customer names and are stored as text.

A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key. Each table can only have one

primary key.

The primary key of this table is the ISBN, which uniquely identifies a book. The title column relates to the book; this is the title of the book. Each row of this table is about one book.

In cell E14, enter a date function that calculates the number of days between the Initial Deadline (cell E10) and the Date Received for the first student (D14). Use mixed and relative references appropriately. Copy the function to the range E15:E68. A negative value indicates the application was received after the initial deadline.

Answers

Answer:

The formula to enter in E14 is as follows:

=DAYS(D14,$E$10)

Explanation:

Required

Formula to calculate the number of days between E10 and D14

The syntax to do this is:

=DAYS(end_date,start_date)

So, we have:

=DAYS(D14,E10)

The question requires a mix of relative and mixed references because cell E10 will be constant in calculating the difference for dates in other cells.

In other words, the initial date is constant for all

So, the update formula is:

=DAYS(D14,$E$10)

Notice the $ between in E10; this represents mixed referencing

When dragged to E15 till E68, the formulas in the respective cells will be:

=DAYS(D15,$E$10) .............................. =DAYS(D68,$E$10)

Convert the algebraic expression below to C++ statement Do not use the pow function. Ans = 5x^2 + 15k + y^-2

Answers

Answer:

The C++ statement for the given algebraic expression 5x^2 + 15k + y^-2 is ( ( 5 * ( x * x ) ) + ( 15 * k ) + ( 1 / ( y * y ) ).

Explanation:

To convert the given algebraic expression 5x^2 + 15k + y^-2 into the C++ statement without using the pow function is:

In the given algebraic expression, there are three expressions combined using the + operator.

The first algebraic expression is 5x^2.

Here, x has a power of 2, and 5 is multiplied by the result of x^2. x having the power of 2 means x is multiplied itself twice. The C++ statement for this algebraic expression is (5 * ( x * x)).

The second algebraic expression is 15k.

Here, 15 is multiplied by k. The C++ statement for this algebraic expression is (15 * k).

The third algebraic expression is y^-2.

Here, x has a power of -2. it means [tex]1/y^{2}[/tex].  The C++ statement for this algebraic expression is (1/ (y * y).

The combination of all the three C++ statement is (5 * ( x * x)) + (15 * k) + (1/ (y * y).

is solar energy reliable and powerful enough to be used in home or business​

Answers

Answer:

It all depends on what you are prepared to spend and what sort of system you install. I have both grid tie and stand alone systems installed at my home, and both work really well, although we initially had some inverter problems with the grid tie system until we decided to only use top shelf gear.

We have 6.6 kW grid tie system on the roof of the house which supplies around 3 times our requirements, and a 1.5 kW stand alone system that supplies the backyard workshop and pool pump. The grid tie system cost around $6500 to install, and the small stand alone system cost $4500 although this was designed and built by myself, so a purchased system may well be more (batteries are still expensive, but this price is coming down).

In the current configuration (top tier panels, Fronius grid tie inverter and Victron stand alone inverter and charge regulator), we have had no failures in several years, and power bills are something that happen to other people.

My advice is look at what your requirements are, then double that when you spec out your system and don’t go for the cheapest price. Buy your components based on the quality and reputation of the manufacturer, it will be expensive, but you will save money in the long run. A good manufacturer will guarantee their products for at least 12 years and you should expect to get at least 20 years of life out of them.

Explanation:

Solar energy is more than enough for any business or home, but if you want to know if it is cost effective, you need to run the numbers. It does have to be grid-tied though to provide electricity at night or when cloudy for multiple days. In most cases, batteries are not cost-effective at this time.

in what century was plastic invented ?​

Answers

Answer:

Explanation:

XIX°

1862 : the  Parkésine  (Alexander Parkes )

Answer: 19th century

Explanation:

Plastic was invented by Alexander Parkes in Birmingham, England, with the name "Parkesin", a mixture of nitrocellulose, camphor and alcohol. At that time, rubber was used for materials to be shaped with molds instead of plastic. Parkes showed his invention to the world in 1862 at the Great International Fair. His invention won a bronze medal. Due to the high cost of rubber, Alexander Parkes' invention attracted great attention.

Possibly the largest number of different polymeric materials come under the plastic  classification. Plastics are materials that have some structural rigidity under load,  and are used in general-purpose applications.Polyethylene, polypropylene, poly(vinyl  chloride), polystyrene, and the fluorocarbons, epoxies, phenolics, and polyesters may  all be classified as plastics. They have a wide variety of combinations of properties.

Some plastics are very rigid and brittle (Figure 15.1, curve A). Others are flexible,  exhibiting both elastic and plastic deformations when stressed, and sometimes experiencing considerable deformation before fractureThere are many different polymeric materials that are familiar to us and find a wide  variety of applications; in fact, one way of classifying them is according to their enduse.

Which of the following statements is true? a Test generators eliminate the need for human testers. b Testers are poor programmers. c Test generators produce error free code. d Test generators are faster than human testers.

Answers

Answer:

d. Test generators are faster than human testers

Explanation:

Test generators are automated testing applications used for testing by making use of artificial intelligence such as bots to take the place of actual users of the software or system to operate the software and detect bugs as well as other primary issues related to the functioning of the tested application

The test generators making use of automated testing are able to run through a developed application in much less time than human testers with the capability to give an analysis of the collected data

Test generators are however test generators are not adequate for carrying out a customer validation program which also include going over documentation and assessing product perception

Therefore, the correct option is test generators are more faster when testing than human testers.

Your company resides in an area with rapid growth in both the corporate and residential areas surrounding your office. As such, your company has been experiencing several brownouts due to power grid problems (too much demand and not enough electricity). Fearing that your computers (especially the servers) could be damaged by these brownouts, your manager has asked you to find a solution to this problem.
Which of the following would be the BEST device to recommend to your manager for computer protection?
A. Surge suppressor
B. Power strips
C. UPS
D. Wall Outlet

Answers

Answer:

The correct answer is option C (UPS).

Explanation:

Since brownouts are reduced voltages that might not be good enough for the required electricity capacity for your company, fearing that your computers (especially the servers) could be damaged, it is best to use UPS for your computer protection.

A UPS also called (Uninterruptable Power Supply) can function as a Surge suppressor when the voltages entering your company might be higher than normal, it can also function too in protecting your computers (especially the servers) in the case of a brownout when voltage required by your computers dropped below the required level. In the case of a brownout, the  UPS supplies energy stored in its batteries to make the computers keep working without going off from lack of electricity.

What is simulation software?

The process of simulating a genuine phenomenon with a set of mathematical formulas is the foundation of simulation software. It is essentially a program that allows the user to simulate an operation and view it without really conducting it.

Simulation is a decision-making and decision-support tool. You can use simulation software to assess, compare, and optimize different designs, programs, and policies. As such, it can be used to explain and defend decisions to multiple stakeholders.

By allowing the corporation to evaluate concepts early in the process before prototype automobiles are constructed, simulation software can save the company money.
