   long number;

   //constructor to set number

  largeintegers(long number){

      this.number=number;

Create a method called letterGrade that will pass the student's average grade as a parameter and return a letter grade (char). Once passed, use an if..else if structure to determine whether the student has an A, B, C, D, or F. Return that letter grade. Use the standard grade scale: 90-100 (A), 80-89 (B), 70-79 (C), 60-69 (D), 0-59 (F).

Answers

Answer:

The method in Java is as follows:

public static char letterGrade(int average){

    char grade =' ';

    if(average>= 90 && average <=100){ grade ='A'; }

    else if(average>= 80 && average <=89){ grade ='B'; }

    else if(average>= 70 && average <=79){ grade ='C'; }

    else if(average>= 60 && average <=69){ grade ='D'; }

    else if(average>= 0 && average <=59){ grade ='F'; }

    return grade;

}

Explanation:

This defines the method

public static char letterGrade(int average){

This initializes the grade to a blank

    char grade =' ';

If average is between 90 and 100 (inclusive), grade is A

    if(average>= 90 && average <=100){ grade ='A'; }

If average is between 80 and 89 (inclusive), grade is B

    else if(average>= 80 && average <=89){ grade ='B'; }

If average is between 70 and 79 (inclusive), grade is C

    else if(average>= 70 && average <=79){ grade ='C'; }

If average is between 60 and 69 (inclusive), grade is D

    else if(average>= 60 && average <=69){ grade ='D'; }

If average is between 0 and 59 (inclusive), grade is F

    else if(average>= 0 && average <=59){ grade ='F'; }

This returns the grade

    return grade;

why absolute reference is used in spreadsheet

Answers

Answer:

Absolute reference is used especially to keep the value or content of a column or row constant.

Explanation:

Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.

In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.

i. relative referencing

ii. absolute referencing

iii. mixed referencing

Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.

Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.

Mixed reference is a hybrid of the relative and absolute references.

1. Design pseudocode for a program that will permit a user to store exactly 75 numbers in an array. Create an array big enough to hold the numbers and store each number in the array as it's entered. Be sure to PROMPT the user for each number before it's entered. You do not need to initialize the array. HINTS: Make sure you use a named constant when you declare the array (the number inside the brackets should be a named constant that you declared before the array declaration.) Use a for loop (or while loop if you'd like) to get each number from the user. The module has an example of pseudocode very similar to this problem. You're free to use this pseudocode as you create your program. 2. Identify three advantages of arrays. For each advantage, write at least one complete sentence explaining why the advantage you listed is an advantage. More detail is better. You may use outside resources but be sure to CITE those resources using APA format.

Answers

Answer:

Question 1: The pseudocode is as follows:

int n = 70;

   int intArray[n];

   for(int i = 0; i< n; i++){

       print("Input "+(i+1)+": ")

       input intArray[i];

   }

Question 2: Advantages of array

Indexing in arrays in easyIt can be used to store multiple values of the same typeIt can be used for 2 dimensional inputs

Explanation:

Question 1

This declares and initializes the length of the array

int n = 70;

This declares the array

   int intArray[n];

This iterates through the length of the array

   for(int i = 0; i< n; i++){

This prompts the user for inputs

       print("Input "+(i+1)+": ")

This gets input for each element of the array

       input intArray[i];

   }

Question 2

Indexing: Elements of the array can easily be accessed through the index of the element.

For instance, an element at index 2 of array intArray can be accessed using: intArray[2]

Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.

2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).

An illustration is:

intArray[2][2] = {[0,1],[3,5]}

The above array has 2 rows, 2 columns and 4 elements in total.

For which of the following values of A and B will the expression A || B be true?

Answers

Answer:

A = False, B = True

Explanation:

|| is equal OR. To the expression be true, you need one of them to be true or both.

A = TRUE, B = FALSE

Returns true

A = FALSE, B = FALSE

Returns true

A = TRUE, B = TRUE

Returns true

Explanation:

The best way to do this would be to use the following line of code

clear: left;

This would make sure that there are no floating elements (li's in this scenario) on the left side of each element. Which in this navigation list would be each individual element, causing it to move each element underneath the previous element. Therefore the entire CSS code would be

.horizontal li {

   display: block;

   width: 12.5%;

   float: left;

   clear: left;

   }

A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.

Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

Explanation:

A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are taken in the steady state for this system with the following results:

Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits

The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.

Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?

Answers

Answer:

a) 15.24 kbps

b) 762 bits

Explanation:

Using little law

a) Determine the average arrival rate (  λ  ) in units of packets/s

λ  = r / Tr  --- 1

where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 ))  = 0.0656

back to equation 1

λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps

b) Determine average number of packets w to be served

w =  λ * Tw =  15243.9 * 0.05 = 762.195 ≈ 762 bits

Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);

Answers

Answer:

The valid operations are:

*q = *(&a[0]);  and q = &(*p);

Explanation:

Given

The above declarations

Required

The valid operations

*q = *(&a[0]);  and q = &(*p); are valid assignment operations.

However, q = &&a[0]; q = &&a; are invalid because:

The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.

Hence, *q = *(&a[0]);  and q = &(*p); are valid

Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler
