A company is considering making a new product. They estimate the probability that the new product will be successful is 0.75. If it is successful it would generate $240,000 in revenue. If it is not successful, it would not generate any revenue. The cost to develop the product is $196,000. Use the profit (revenue − cost) and expected value to decide whether the company should make this new product.

Answer:

ALTER TABLE Products

ADD Products_price float(5,2) DEFAULT 9.99,

ADD Adding_time datetime;

Explanation:

So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.

Then, as per question, we need to add two columns.

The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.

And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

Answer:A declaration defines an identifier (such as the name of a function or variable) that ... This topic introduces the Delphi language character set, and describes the syntax for ... The Delphi language uses the Unicode character encoding for its character set, ... Integer and real constants can be represented in decimal notation as ...

Explanation:

Answer:

total = 0

k = 1

while k <= 50:

total += k**2

k += 1

print(total)

Explanation:

Note: There some errors in the question. The correct complete question is therefore provided before answering the question as follows:

Use the variables k and total to write a while loop that computes the sum of the squares of the first 50 counting numbers, and associates that value with total. Thus your code should associate 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 with total. Use no variables other than k and total.

The answer is now explained as follows:

# Initialize k which is the number of term

k = 1

# Initialize total which is the sum of squares

total = 0

# Loop as long as k is less than or equal to 50.

while (k <= 50):

# Add the square of k to total in order to increase it

total = total + k * k

# Increase the value of k by one.

k += 1

# Finally, output total

print (total)

Answer:

(b) srand(time(0))

Explanation:

Given

See attachment for options

Required

Which would generate different set of random numbers

To do this, we analyze each of the options - one at a time.

(a) srand()

The above is an invalid usage of srand() because srand() requires an argument for it to function e.g. srand(2)

(b) srand(time(0))

The above is valid, and it will return different pseudo random numbers each time the statement is executed because time(0) lets srand() seed to the current time.

(c) srand(100)

The above is a valid usage of srand(), however rand() will generate same set of numbers because srand() has been seeded to only 100.

(d) time(srand())

The above is also an invalid usage of srand().

Answer: it is also known as supervised learning

Explanation:

Deep learning is a sub field of machine learning and it refers to an artificial intelligence function that has to do with the imitation of the way that the brain works in the processing data which are used in making decisions.

It should be noted that deep learning is not thesame as supervised learning. While there's no creation of high-level abstraction of input features in the supervised learning, there's formation of abstractions of input features in deep learning.

Answer:

Acronis True Image is the one I would recommend out of these mentioned online backup services.

Explanation:

The evaluations and reviews of each of the online backup services are as follows:

a. iDrive

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 88% - very good

Features = 95% - excellent

Pricing = 85% - Very good

Because of its various features, pricing, and usability, IDrive reviews suggest that it is a very efficient online backup solution. However, there have been complaints concerning its speed and the fact that there are no monthly plans available.

b. Carbonite

For this, we have:

Speed = 60% - fair

Security = 100% - excellent

Privacy = 87% - very good

Pricing = 85% - very good

File backup and restoration = 75% - good

Carbonite reviews reveal that it is simple to use and provides limitless backup for one device. The main drawback is that it has extremely poor backup speeds.

c. Acronis True Image

This is fast, simple and intuitive

It has complete control over the backup updates, including how and when they occur.

It is not expensive.

Acrnonis True image is a powerful backup storage service. It enables data and file backup and restoration from USB drives.

Many reviewers of Acrnonis True image have stated that they have had no issues with its service, that it is worth purchasing, and that there are no concerns.

d. Backblaze

For this, we have:

Speed = 75% - good

Security = 75% - good

Privacy = 70% - decent

Pricing = 100% - excellent

Support = 95% - excellent

Features = 65% - decent

File back-up and restoration = 70% - decent

Backblaze is one of the most popular internet backup services. This storage service, however, does not allow for ustomization.

Recommendation

Acronis True Image is the one I would recommend out of these mentioned online backup services. This is due to the fact that it delivers a large amount of accurate and high-quality data storage. It is quick, simple and intuitive, which is what most people care about. Furthermore, reviewers have stated that this service is quite effective and that there have been very few issues with it. The other services demonstrate that their services have flaws, such as lack of customization and slowness.

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

    else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

    else{

        System.out.print("The circles intersect");     }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

If the distance is greater than the sum of both radii, then the circles do not touch one another

   else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

If the distance is less than the sum of both radii, then the circles intersect

   else{

        System.out.print("The circles intersect");     }

}

Answer:

b. False

Explanation:

Decomposing and modularizing means that a large software is being divided into smaller named components that have a well-defined interfaces which basically describes the component interactions. The main goal is to place these different functionalities as well as the responsibilities in different components.

Decomposition and modularization forms the principle of software design.

The complete method is as follows:

public List buildList(List L) {  

 L.insert(30);

 L.insert(23);

 L.insert(19);

 L.insert(4);  

   return L; }

Explanation:

To complete the method, we make use of the insert() function.

This inserts elements of the list into list L. However, we have to start from the last element (i.e. in descending order)

So, the explanation is as follows:

 L.insert(30); --- This inserts the last element

Continue inserting in descending order

 L.insert(23);  

 L.insert(19);

Until the first list element is inserted

 L.insert(4);

This returns the filled list L  

   return L;

A class of ArrayList is a redimensionable array in java. During built-in arrays, ArrayLists can dynamically change their size. Elements can be added and removed from an ArrayList when necessary, which helps the user handle this same memory, and the method described can be defined as follows:

Method code:

public List buildList(List L)//defining a method buildList that takes List variable L in parameter

{

L.insert("30");//Calling insert method that takes a value in parameter.

L.insert("23");//Calling insert method that takes a value in parameter.

L.insert("19");//Calling insert method that takes a value in parameter.

L.insert("4");//Calling insert method that takes a value in parameter.

L.next();//calling next method that prints list value

L.next();//calling next method that prints list value

   return L;//return list value L

}

Answer:

The function is as follows:

def number_of_pennies(dollars,pennies=0):

   return dollars*100+pennies

Explanation:

This defines the function

def number_of_pennies(dollars,pennies=0):

This returns the number of pennies

   return dollars*100+pennies

Note that, if the number of pennies is not passed to the function, the function takes it as 0

Answer:

Code is given as:-

#number_of_pennies function with one default argument with pennies as 0 when no pennies parameter is given

def number_of_pennies(dollars,pennies = 0):

  pennies = dollars*100 + pennies #one dollar equals 100 pennies so calculate total pennies with this formula

  return pennies #return total pennies

print(number_of_pennies(int(input()),int(input()))) #both Dollars and pennies

print(number_of_pennies(int(input()))) #Dollars only

Memorandum.

To: IT class.

From: Professor Smith.

Date:

Dear students,

The purpose of this memorandum is to let you all know the requirements of an ideal computer room.

1.- The compute room should be a decent, large, space, ready to accommodate the number of students that are going to participate in class.

2.- The proper temperature levels. All the hardware can't stand too much heat. We need ventilators and the right temperature for safety purposes.

3.- The organization of the PCs on every desk must be precise in order to have enough room for everybody's participation and interaction.

4.- Have a proper fire suppression system in place. The risk of fire when working with electronics is considerable.

5.- Access control. The equipment is expensive and must be just for qualified students. Have the proper control-access system to keep the place safe.

Thank you for your attention.

With your cooperation, the computer room should be a place to learn and have fun learning new things.
