An online article in 2001 described a study in which twelve sixth-grade students who had not previously played chess participate

d in a program where they took chess lessons and played chess daily for 9 months. Each student took a memory test (the Test of Cognitive Skills) before starting the chess program and again at the end of the 9 month period. Data and computed differences are given in the accompanying table. The author of the article proposed using these data to test the theory that students who participated in the chess program tend to achieve higher memory scores after completion of the program.

Acceleration is the rate at which an object changes its velocity. It is typically represented by symbol a and measured in m/s2 (
Natalija [7]

Answer:

<u>Pseudocode:</u>

INPUT velocity

INPUT time

SET velocity = 0.44704 * velocity

SET acceleration = velocity / time

SET acceleration = round(acceleration, 1)

PRINT acceleration

<u>Code:</u>

velocity = float(input("Enter a velocity in miles per hour: "))

time = float(input("Enter a time in seconds: "))

velocity = 0.44704 * velocity

acceleration = velocity / time

acceleration = round(acceleration, 1)

print("The acceleration is {:.2f}".format(acceleration))

Explanation:

*The code is in Python.

Ask the user to enter the velocity and time

Convert the miles per hour to meters per second

Calculate the acceleration using the formula

Round the acceleration to one decimal using round() method

Print the acceleration with two decimal digits

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combinin
Dmitry_Shevchenko [17]

Answer:

Follows are the code to this question:

#include<iostream>//defining header file

using namespace std;// use package

int main()//main method

{

int red,green,blue,x;//declaring integer variable

cin>> red >>green>>blue;//use input method to input value

if(red<green && red<blue)//defining if block that check red value is greater then green and blue  

{

x = red;//use x variable to store red value

}

else if(green<blue)//defining else if block that check green value greater then blue  

{

x= green; //use x variable to store green value

}

else//defining else block

{

x=blue;//use x variable to store blue value

}

red -= x;//subtract input integer value from x  

green -=x; //subtract input integer value from x

blue -= x;//subtract input integer value from x

cout<<red<<" "<<green<<" "<<blue;//print value

return 0;

}

Output:

130 50 130

80 0 80

Explanation:

In the given code, inside the main method, four integers "red, green, blue, and x" are defined, in which "red, green, and blue" is used for input the value from the user end. In the next step, a conditional statement is used, in the if block, it checks red variable value is greater than then "green and blue" variable. If the condition is true, it will store red variable value in "x", otherwise, it will goto else if block.

  • In this block, it checks the green variable value greater than the blue variable value. if the condition is true it will store the green variable value in x variable.
  • In the next step, else block is defined, that store blue variable value in x variable, at the last step input variable, is used that subtracts the value from x and print its value.
