Answer:

The description for the given question is described in the explanation section below.

Explanation:

  1. Note that 20 programs or files are programmed into the storage at this time.
  2. The operating system is idle at a certain moment, waiting for both the I/O action by the 20 programs.
  • Each system is estimated to be investing 80 percent (0.8) of the waiting period.
  • Multiply the processing time among all 20 initiatives, to assess the likelihood.

          ⇒  0.8 ^ 20 = 0.012

  • Assess the possibility of twenty services to assess the processing time utilization.
  • Subtract the product of 20 programs from 1. To assess the likelihood.

         ⇒ 1 - 0.012 = 0.988

The CPU then spends 98.9 percent of its time on 20 applications.

       {

           String [] exams = {"1;2;3;4;" , "5;6;7;8;" , "9;10;11;12;" };

           double[][] n = new double[exams.length][4];

           examArray = convert(exams , exams.length , 0 , n);

           for(int i = 0 ; i < exams.length ; i++)

           {

               for(int j = 0 ; j < 4 ; j++)

               {

                   System.out.print(n[i][j] + "\t");

               }

              System.out.print("\n");

           }

       }    

       

/* recursive function convert defined here */

       public static double[][] convert(String[] exams , int number , int x , double [][] result)

       {

           if(x==number)

               return result;

           else

           {

               String total = exams[x];  

               String currentScore = "";

               int p = 0;

               for(int j = 0 ; j<totalScore.length() ; j++)

               {

                   char ch = total.charAt(j);/

                   if(ch==';')

                   {

                       result[x][p] = Double.parseDouble(currentScore);

                       p++;

                       currentScore = "";

                   }

                   else

                   {

                       currentScore = currentScore + Character.toString(ch);

                   }

               }

               return convert(exams , number , x+1 , result);

           }

           

       }

}

Explanation:

The Java source code defines a recursive function or method called convert that converts the results of three students that sat for four examinations to double or float number and screens their individual results for the four exams on the screen.

Using the phase plane program, plot the phase plane for the Lotka-Volterra model:
ivanzaharov [21]

Answer:

yes, the model gives a realistic behavior

Explanation:

This describes the inner equilibrium point is a stable node, here it's a center. These are periodic solutions. Populations of the mice and owls are periodic. It describes: when the mice population is lower, the owl population decreases; again the owl is lower so mice got a chance to grow its population; now as sufficient food(mice) is there, the owl population increases; as predator population increases, the prey population decreases; and this continues as a cycle forever.

So, yes, the model gives a realistic behavior.

vovangra [49]

Complete Question:

Missy loves her old Windows games. When she upgrades her Windows system, the games run fine, but the output looks fuzzy since the programs are designed only to run in VGA mode.

Group of answer choices;

A. Reboot into Safe Mode

B. Run compatibility mode for 640 x 480 resolution.

C. Reduce her screen resolution to 640 x480

D. Reboot into Low Resolution Mode

Answer:

B. Run compatibility mode for 640 x 480 resolution.

Explanation:

In this scenario, Missy loves her old Windows games. When she upgrades her Windows system, the games run fine, but the output looks fuzzy since the programs are designed only to run in VGA mode. In order to make the games work properly in Windows, Missy should run compatibility mode for 640 x 480 resolution.

The video graphics array (VGA) is the standard graphics or display interface used for computer monitors. It was developed in 1987 by IBM and it had a standard display resolution of 640 x 480 pixels.

<em>Hence, if the output of a software program (games) looks fuzzy or is not being displayed properly, you should run compatibility mode for 640 x 480 resolution. This is to enable low resolution video mode on the computer. </em>

The VGA mode is very basic because only minimal video drivers are being loaded on the windows.
