Answer:

-16000

Explanation:

Given

P(success) = 0.75

Amount generated on success, X = 240000

P(not successful) = P(success)' = 1 - 0.75 = 0.25

Revenue generated, 0

Product development cost = 196000

Profit = Revenue - cost

When successful ; 240000 - 196000 = 44000

Unsuccessful ; 0 - 196000 = - 196000

x __________ 44000 _____ - 196000

P(x) _________ 0.75 _________ 0.25

The expected value ; E(X) = Σx * p(x)

Σx * p(x) = (44000 * 0.75) + (-196000 * 0.25)

= 33000 + - 49000

= - 16000

Hence, the company should not make the product

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().

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.

Hence, the answer is false.

The statement that  is true is that  Network traffic can be captured using the Tcpdump protocol analyzer.

Network traffic can be taken in using the Tcpdump. This is known to be a kind of packet sniffer that is often used to look and record network traffic on an interface.

An example is when a person capture 1,000 packets through the use of tcpdump. One can then analyze network traffic by using actual network traffic analyzer, which is as Wireshark.

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)

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.

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:

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 ...

Answer:

1) The value of x will be 6.

2) The value of y will be 7.

Explanation:

1) The value of x will be 6.  

The enum values are labeled by default from 1. This means that Sun = 1, Mon = 2, Tue = 3 and so on.  

So, x = Mon = 2 and y = Sat = 6  

x increases up to y = 6 in the while loop.  

and then y also increments by 1.  

2)So the value of y = 7.  

You will need actual printf("Sun") or printf("Mon") for printing the actual text for the enum.

Answer:

dog

Explanation:

Given the code :

>>> A = [21, 'dog', 'red']

>>> B = [35, 'cat', 'blue')

>>> C = [12, 'fish', 'green']

>>> E = [A, B, C]

the value of E[0][1]

Here, square boxes is used to select the value at E[0] ; the output is then used to select the value at index 1 of E[0] output.

Note that, indexing starts at 0; hence first list element is 0, then, 1, 2, and so on.

At

E[0] ; list E, index 0 (first element in the list) , gives an output A

Then, A[1] ; list A, index 1 (second element in the list) gives 'dog'

Explanation:

By the way, a computer is not an acronym and is the name of an electronic device.

A computer is a simple machine that we can program for a lot of logical and arithmetic functions, and it executes our work according to our instructions.

in simple words, a computer is an electronic device that makes our work easy, and any computer that has been programmed for some set of works, it performs that task or works quickly and correctly.

Answer:

In half duplex mode, the signal is sent in both directions, but one at a time. In full duplex mode, the signal is sent in both directions at the same time. In simplex mode, only one device can transmit the signal. In half duplex mode, both devices can transmit the signal, but one at a time.

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");     }

}
