1. For this assignment you will print the steps for 8-bit by 8-bit multiplication.
2. Your program should read in two unsigned numbers from stdin, the first being the multiplicand and the second being the multiplier. Your program should verify that both values are within the range 0 to 255. If not, the program should print an appropriate error message and exit.
3. Your program should then initialize the simulated registers and echo the input values in decimal and also in binary.
4. Then your program should illustrate the eight steps required for multiplication using the same type of step diagrams as given in the lecture notes.
5. Finally, your program should print a check section that shows a summary of the multiplication in binary as well as in decimal. See the example below.
6. You may write your program in C, C++, or Java. If you choose to work in C, here is an example function that will allow you to represent an n-bit value within an int data type and print out the binary value in "length" bits. It uses the shift right operator and the bitwise and. (You can also choose to use unsigned int as the data type; since you are using only the lower 8 of the 32 bits in an int, there will be no apparent difference between using int and using unsigned int. However, if you choose to use char as the data type, you should use unsigned char to ensure that the compiler generates logical rather than arithmetic shifts.)
void prt_bin( int value, int length ){
int i;
for( i=(length-1); i>=0; i--){
if((value>>i)&1)
putchar('1');
else
putchar('0');
}
}
For example, if you declare acc as an int, then you could call prt_bin(acc,8) to print the 8-bit value in the accumulator.
You should format your output to exactly match the output below. 10% of the grade will be awarded for following the same format.

what is incremental development and its importance in a project

Answers

Answer:

Incremental development in software engineering is a process methodology that emphasizes the virtue of taking small steps toward the goal.

Explanation:

Rather than delaying feedback until final delivery when time and resources have already been spent, incremental development ensures that teams can use feedback to make changes early and often.

The main importance of the Incremental model is that it divides the software development into submodules and each submodule is developed by following the software development life cycle process SDLC like Analysis, Design, Code, and Test.

Answer:

 incremental development is any combination of both iterative design or iterative method and incremental build model for development

Explanation:

importance

Incremental development ensures that developers can make changes early on in the process rather than waiting until the end when the allotted time has run out and the money has been spent.

An incremental approach breaks the software development process down into small, manageable portions known as increments. Each increment builds on the previous version so that improvements are made step by step

Calculate the total time required to transfer a 500KB file in the following cases. Assume an RTT of 50ms, a packet size of 2KB, and an initial 2xRTT of handshaking before data is sent. A. If the bandwidth is 2Mbps, what is the Bandwidth-Delay Product (BDP)

Answers

Answer:

i) Total time = 2457.73 secs

ii) BDP = 0.01 Mbyte

Explanation:

Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits

Bandwidth : 2Mbps = 2,000,000 bits/sec

RTT = 50 ms = 0.050 secs

i) Determine total time required to transfer 500 kB

= Initial handshake + Time for transmission of all files + propagation delay

= 2 x RTT +  Time for transmission + RTT /2

Total time = ( 2 * 0.05 ) +  (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs

ii) Determine the Bandwidth-delay product

= data link capacity * RTT

= 2 Mbps  * 50 ms =  100,000 =  0.01 MByte

Answers

Answer:

Explanation:

The following is written in Python. It takes in a file, it then reads all of the elements in the file and adds them to a list called myList. Then it sorts the list and uses the elements in that list to calculate the median. Once the median is calculated it returns it to the user. The code has been tested and the output can be seen in the image below.

def find_median(file):

   file = open(file, 'r')

   mylist = []

   for number in file:

       mylist.append(int(number))

   numOfElements = len(mylist)

   mylist.sort()

   print(mylist)

   if numOfElements % 2 == 0:

       m1 = numOfElements / 2

       m2 = (numOfElements / 2) + 1

       m1 = int(m1) - 1

       m2 = int(m2) - 1

       median = (mylist[m1] + mylist[m2]) / 2

   else:

       m = (numOfElements + 1) / 2

       m = int(m) - 1

       median = mylist[m]

   return median

print("Median: " + str(find_median('file1.txt')))

A life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would be most likely to:________
a. emphasize that his company is one of the largest in the insurance industry.
b. promise a free gift to those who agree to purchase an insurance policy.
c. address customers by their first names.
d. ask customers to respond to a brief survey of their attitudes regarding life insurance.

Answers

Answer:

d. ask customers to respond to a brief survey of their attitudes regarding life insurance.

Explanation:

A life insurance policy can be defined as a contract between a policyholder and an insurer, in which the insurer agrees to pay an amount of money to a specific beneficiary either upon the death of the insured person (decedent) or after a set period of time.

A salesperson (sales representative) refers to an individual or employee who is saddled with the responsibility of taking orders from customers, as well as selling finished goods and services to consumers or end users.

A foot-in-the-door phenomenon can be defined as a compliance (persuasive) technique or tactics that assumes a person agreeing to perform a small request increases the likelihood of he or she agreeing to a subsequent larger request. Thus, it posits that when a person agrees to a small, it makes it difficult for him or her to decline a second, larger (bigger) request.

In this context, a life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would most likely ask his or her customers to respond to a brief survey of their attitudes regarding life insurance.

Does the estimate of a tolerance level of 68.26% of all patient waiting times provide evidence that at least two-thirds of all patients will have to wait less than 8 minutes?

Answers

Answer:

Yes, because the upper limit is less Than 8 minutes

Explanation:

According to the empirical formula :

68.26% of data lies within 1 standard deviation from the mean;

Hence,

Mean ± 1(standard deviation)

The sample mean and sample standard deviation of the given data is :

Sample mean, xbar = Σx / n = 546 / 100 = 5.46

Sample standard deviation, s = 2.475 (Calculator)

The interval which lies within 68.26% (1 standard deviation is) ;

Lower = (5.460 - 2.475) = 2.985

Upper = (5.460 + 2.475) = 7.935

(2.985 ; 7.935)

Since the interval falls within ; (2.985 ; 7.935) whose upper level is less than 8 means patients will have to wait less Than 8 minutes.

The action to take is to:

Delete the .(root) zone from the DNS2.  Then configure conditional forwarding on the DNS2 server.  If this is not done, the users will be unable to access the internet.

Explanation:

DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name.  This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.

So we can maintain high quality designs at any graphic scale.

Explanation:

Unlike other graphic formats which simply define colors for fixed pixels, vector graphics define points and shapes (vectors) which are then used to draw the graphic at the desired and appropriate resolution.

Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.

Answer:

[tex]\tan(x+y) = 3.73[/tex]

Explanation:

The missing part of the question are:

[tex]\sin(x) = \frac{1}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]

Required

[tex]\tan(x + y)[/tex]

First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]

We have:

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So:

[tex](1/2)^2 + \cos^2(x) = 1[/tex]

Collect like terms

[tex]\cos^2(x) = 1 - (1/2)^2[/tex]

[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]\cos^2(x) = \frac{4-1}{4}[/tex]

[tex]\cos^2(x) = \frac{3}{4}[/tex]

Square roots of both sides

[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

Similarly,

[tex]\sin^2(y) + \cos^2(y) = 1[/tex]

So:

[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]

[tex]\sin^2(y)+ (2/4) = 1[/tex]

[tex]\sin^2(y)+1/2 = 1[/tex]

Collect like terms

[tex]\sin^2(y) = 1 - 1/2[/tex]

Take LCM

[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]

[tex]\sin^2(y) = \frac{1}{2}[/tex]

Square roots of both sides

[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]

Rationalize

[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

So, we have:

[tex]\sin(x) = \frac{1}{2}[/tex]           [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]        [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]

[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]

Rewrite as:

[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]

[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]

Rationalize

[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]

Similarly

[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]

[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]

[tex]\tan(y) = 1[/tex]

Lastly,

[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]

Combine fractions

[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]

Cancel out 3

[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]

Using a calculator

[tex]\tan(x+y) = 3.73[/tex]

I have a variable and set it equal to 5. 1 then send it as an argument to a function that adds 5 to the variable passed in. Outside the function print the variable (after the function executes).
What will it print?
A. 5+1
B. 4
C. 6
D. 5

Answers

Answer:

D. 5

Explanation:

If the variables original value was 5 then the value that will be printed is 5. This is because the variable is being passed as a parameter into the function and 5 is being added to the parameter value, not the actual global variable outside. Therefore, in order for the adjusted value to be printed then that new value that is returned by the function needs to be saved in a new variable. This can be seen in the example code below.

Cryptarithmetic algorithm

Answers

Answer:

CryptArithmetic or verbal arithmetic is a class of mathematical puzzles in which the digits are replaced by letters of the alphabet or other symbols. Usually it is required that each letter would be replaced by a unique digit. Each letter having different value from the other letters.

Explanation:

Cryptarithm now denotes mathematical problems usually calling for addition, subtraction, multiplication, or division and replacement of the digits by letters of the alphabet or some other symbols. ... Since D × B has only one digit, B must be 3 or less. The only two possibilities are 0 and 2.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.

Answers

Answer and Explanation:

Using JavaScript:

/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/

function chocolatebar(dollars){

var dollaramt= dollars;

var i;

for(i=0; i <= dollaramt; i++){

i=i+6

?

Alert ("you have 1 extra chocolate bar");

:

Alert ("keep buying chocolate bars to get more coupons for a bonus chocolate bar")

}

Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting.

Answers

Answer:

Code:-  

# function to print the pattern

def draw_triangle(n, num):

     

   # base case

   if (n == 0):

       return;

   print_space(n - 1);

   print_asterisk(num - n + 1);

   print("");

 

   # recursively calling pattern()

   pattern(n - 1, num);

   

# function to print spaces

def print_space(space):

     

   # base case

   if (space == 0):

       return;

   print(" ", end = "");

 

   # recursively calling print_space()

   print_space(space - 1);

 

# function to print asterisks

def print_asterisk(asterisk):

     

   # base case

   if(asterisk == 0):

       return;

   print("* ", end = "");

 

   # recursively calling asterisk()

   print_asterisk(asterisk - 1);

   

# Driver Code

n = 19;

draw_triangle(n, n);

Output:-  

# Driver Code n = 19;| draw_triangle(n, n);
