Answer 1

Ответ:

program z;

var o:array [1..19] of integer;

i,s:integer;

begin

randomize;

s:=0;

for i:=1 to 19 do

begin

o[i]:=random(4)+2;

write(o[i],' ');

s:=s+o[i]

end;

writeln;

write(s/19:5:3)

end.

Answer 2

To solve the given task of calculating the average grade in the 9th-grade computer science class, you can write a Pascal program that generates random grades within the range of 2 to 5 (inclusive) and then calculates the average.

Here's an example Pascal program that accomplishes this task:

program AverageGrade;

const
  ARRAY_SIZE = 30; // Define the size of the array (you can change this value as needed)

var
  grades: array[1..ARRAY_SIZE] of Integer; // Declare the array to store the grades
  sum, average: Real; // Variables to store the sum and average

i: Integer; // Loop variable

begin
  Randomize; // Initialize the random number generator

// Fill the array with random grades
  for i := 1 to ARRAY_SIZE do
    grades[i] := Random(4) + 2; // Generate a random number between 2 and 5

// Calculate the sum of grades
  sum := 0;
  for i := 1 to ARRAY_SIZE do
    sum := sum + grades[i];

// Calculate the average grade
  average := sum / ARRAY_SIZE;

// Display the average grade
  writeln('Average grade in the class: ', average:0:2);
end.

To run this program, you can use an IDE or compiler that supports Pascal, such as Free Pascal or Turbo Pascal. After running the program, it will display the average grade in the class.

Please note that the program uses a constant `ARRAY_SIZE` to define the size of the array. You can modify this value to match the desired number of grades in the class. Additionally, the program uses the `Randomize` procedure to initialize the random number generator, ensuring different random grades are generated each time the program is run.

Remember to provide the text of the code and a screenshot of the program's output, including the code and the calculated average grade, for submission.

I hope this helps! Let me know if you have any further questions.
