Answer:

-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂

Explanation:

2's complement is a way for us to represent negative numbers in binary.

To get 2's complement:

1. Invert all the bits

2. Add 1 to the inverted bits

Summary: 2's complement = -N = ~N + 1

1. Inverting the number

3874₁₀ = 1111 0010 0010₂

~3874₁₀ = 0000 1101 1101₂

2. Add 1 to your inverted bits

~3874₁₀ + 1 = 0000 1101 1101₂ + 1

= 0000 1101 1110₂

You can pad the most signigicant bits with 1's if you're planning on using more bits.

so,

12 bits 16 bits

0000 1101 1110₂ = 1111 0000 1101 1110₂

They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.

32 bits

= 1111 1111 1111 1111 1111 1111 1101 1110

Decisions 1 and 3 are both ____________ decisions because ____________________.

Hoochie [10]

The Question given is incomplete so from the internet the complete question is as follows:

Health Day Regional Medical center's management team has several decisions to make. They are attempting to sort out what to do first. The decisions are as follows:

1. Determine which patients to be admitted for the next day.

2. Decide weather or not to purchase the only other medical center in their region.

3. Decide which candidates will meet the requirements for the nursing training program.

4. Determine weather the medical center should diversify into more advanced (and substantially more costly ) technologies.

Decisions 1 and 3 are both ____________ decisions because ____________________.

A. Programmed decisions; they are novel and complex

B. Non programmed decisions; they are novel and complex

C. Programmed decisions; they are can be solved using rules and procedures

D. Non programmed decisions; they are novel and complex

E. None of the above is correct

Answer:

Option C is the correct answer.

Decisions 1 and 3 are both Programmed decisions because they can be solved using rules and procedures .

Explanation:

Programmed Decisions can be defined as the ones that are specified and developed for routine problems that are repetitive. These decisions deal with certainty.

Now from the given list of decisions, it is obvious that the decision 1 and 3 are programmed.

Patients that are to be admitted must undergo through the rules and regulations so that a decision may be taken.
Similarly in the case of nurses, proper testing must be conducted and candidates are selected upon this criteria.

Answer the following questions:

victus00 [196]

Answer:

The answer to the following questions can be given as:

Question: 1

value of foo is = 1020

Question: 2

Output of the code is = false

Question: 3

function add(a, b)

{

return a && b ? a + b : function (c) { return a + c; };

}

var a=add(2,5);

var x=add(2)(5);

print(a);

print(x);

output:

Question: 4

"goh angasal a m'i"

Question: 5

In this we check that if in the window a foo function exists. otherwise we set windows.foo to bar.

Question: 6

first alert shows the value "Hello World";

second alert shows value ReferenceError, In this bar not defined.

Question: 7

The value of foo.length is 2

Question: 8

The value of foo.x is undefined

Question: 9

Function print = "one", "three", "two" .

Question :10

It is difficult to define because doSomethingElse() function is not defined.

Explanation:

In question 1 the value of the foo variable is 1020 because we perform the string concat operation.

In question 2 Output of the code is false because float value keeps in binary and when we convert 0.1 or 0.2 to binary so it is not the same.

In question 3 the output of both functions is 7.

In question 4 the output is goh angasal a m'i because In this code we use the reverse() function, split() function and join() function. Reverse function reverses the value. split function splits the value and join function join all the value of the string in a line.

In question 5 we check the value.

In question 6, the first output is Hello World and second is ReferenceError.

In question 7, the value of foo.length is 2 because this foo array we insert only 2 values.

In question 8, the value of foo.x is undefined because in the variable we reset the value of foo all together, so foo.x value is undefined.

In the question 9 function print "one",

"three",

"two" because In the function first, we print the message that is "one" then we define a function in this function we print the value

"two" but before creating object we call the "three" so the print value is "one",

"three",

"two".

In question 10 function, the output of this function is undefined.

Instructions Write a program that allows the user to enter the last names of five candidates in a local election and the number

KengaRu [80]

Here is code in java.

import java.util.*;

class Election

{ //main method

public static void main(String args[]){

// create an object of Scanner class to read input

Scanner s = new Scanner(System.in);

// string array to store name of candidates

String name[] = new String[5];

// int array to store vote count of candidates

int v_count[] = new int[5];

double p = 0;

int i = 0, sum = 0, high =0, win = 0;

for(i = 0; i < 5;i++)

{

System.out.print("last name of Candidate " + (i+1) + ":");

// read name of Candidate

name[i] = s.next();

System.out.print(" number of votes received: ");

// read vote of Candidate

v_count[i] =s.nextInt();

if(v_count[i] > high)

{

// highest vote

high = v_count[i];

win = i;

}

// total vote count

sum +=v_count[i];

}

// printing the output

System.out.println("\nCandidate\tVotes Received\t% of TotalVotes\n");

for(i = 0; i < 5;i++)

{

// % of vote of each Candidate

p =(v_count[i]*100)/sum;

// print the output

System.out.println(name[i] + "\t\t" + v_count[i] + "\t\t\t" +p);

}

// print the total votes

System.out.println("\nTotal Votes:\t" + sum);

// print the Winner of the Election

System.out.println("Winner of the Election is: " + name[win]);

}

Explanation:

Create a string array "name" to store the name of candidates.Create Integer array "v_count" to store votes os each candidates.Calculate total votes of all candidates and find the highest vote amongst all candidate and print it.Find % of votes received by each candidate.Print these stats.

Output:

last name of Candidate 1:patel

number of votes received: 54

last name of Candidate 2:singh

number of votes received: 76

last name of Candidate 3:roy

number of votes received: 33

last name of Candidate 4:yadav

number of votes received: 98

last name of Candidate 5:sharma

number of votes received: 50

Candidate Votes Received % of TotalVotes

patel 54 17.0

singh 76 24.0

roy 33 10.0

yadav 98 31.0

sharma 50 16.0

Total Votes: 311

Winner of the Election is: yadav
