Answer:
An appropriate precondition is:
0 <= n && n <= str.length() - 1
Explanation:
Required:
Write down an appropriate pre-condition for the program
From the question, we understand that the method accepts two parameters:
str -> A string value
n -> An integer value which represents the index of character to return from the string str
It should be noted that:
n must be within the range of 0 and str.length()-1
Take for instance:
str = "ABCDE";
n must be within the range 0 to 4 (inclusive) in order not to raise an exception. This is so because the string index starts at 0 and stops at 1 less than the length of the string.
Hence, the precondition can be written as:
0 <= n && n <= str.length() - 1
Which means: n = 0 to length - 1

Finish the program to compute how many gallons of paint are needed to cover the given square feet of walls. Assume 1 gallon can cover 350.0 square feet. So gallons = the square feet divided by 350.0. If the input is 250.0, the output should be:
0.714285714286
Answer:
gallons_paint = wall_area / 350.0
Explanation:
So gallons = the square feet divided by 350.0:
So gallons = gallons_paint
the square feet = wall_area
then divide by 350.0
the whole thing:
wall_area = float(input())
# Assign gallons_paint below
gallons_paint = wall_area / 350.0
print(gallons_paint)
The program to compute how many gallons of paints are needed to cover the given square feet's of walls is as follows:
def square_feet_to_gallons(area):
gallons = area / 350
return gallons
print(square_feet_to_gallons(250))
1 gallon covers 350 square feet.
Therefore, gallons = area / 350
The user inputs is the area in square feet. Then the output should be the number of gallons.
The code explanation python.We declared a function named square_feet_to_gallons and the argument is area.
Then we declared a variable and assigned the mathematical operation area/350 to it.
Then we return the gallons.
Finally, we call the function with a print statement.

Consider the following class designed to store weather statistics at a particular date and time:
public class WeatherSnapshot
{
private int tempInFahrenheit;
private int humidity; // value of 56 means 56% humidity
private int dewPoint; // in degrees Fahrenheit
private String date; // stores the date as a String
private int time; // in military time, such as 1430 = 2:30 pm
private boolean cloudy; // true if 25% or more of the sky is covered
// constructor not shown, but it initializes all instance variables
// postcondition: returns temperature
public int getTemp()
{
return tempInFahrenheit;
}
// postcondition: returns date
public String getDate()
{
return date;
}
// postcondition: returns true if precipitation is likely; false otherwise
public boolean precipitationLikely()
{
// implementation not shown
}
// other methods not shown
}
Suppose a WeatherSnapshot object named currentWeather has been correctly instantiated in a client class. Which of the following will correctly call the precipitationLikely method?
A. boolean couldRain = precipitationLikely();
B. boolean couldRain = currentWeather.precipitationLikely();
C. boolean couldRain = currentWeather.precipitationLikely(true);
D. double percentChanceOfRain = precipitationLikely();
E. double percentChanceOfRain = currentWeather.precipitationLikely();
Answer:
The answer is "Option b".
Explanation:
In this question, It took the boolean parameter, which may use the couldRain as the precipitationLikely precipitation method as the boolean variable because the precipitationLikely is not a static type, and it can name this method utilizing object is called currentWeather, that's why the choice b is correct.

Answer:
D
Explanation:
The power relationship on a transformer states that Power in = power out + loss.
What relationship does input and output power have in a transformer?The ratio between output voltage and input voltage exists the exact as the ratio of the number of turns between the two windings
The efficiency of a transformer exists reflected in power (wattage) loss between the primary (input) and secondary (output) windings. Then the consequent efficiency of a transformer stands equivalent to the ratio of the power output of the secondary winding, PS to the power input of the primary winding, PP and exists thus high.
Therefore, the correct answer is option A) Power in = power out + loss.

The CG would move toward the rear.
The CG would stay the same.
The CG would move toward the nose.
O The CG would move lower
Answer:
the CG would move toward the rear.
Explanation:
Adding a paper clip to the vertical stabilizer of your glider will, the CG would move toward the rear. The correct option is A.
What is center of gravity?The place on an item where the force of gravity is thought to act is known as the center of gravity (CG).
The gravitational pull is thought to be focused at the point where an object weighs on average. Depending on the object's size, shape, and mass distribution, the center of gravity will be in one place or another.
The impact of adding a paper clip to your glider's vertical stabilizer is to shift the center of gravity (CG) to the back of the glider.
This is due to the fact that the paper clip adds weight to the glider's rear, moving the center of mass there and, as a result, the center of gravity.
Thus, the correct option is A.

Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.

Conside following prototype of a function
int minArray(int [], int );
Which of the option is correct way of function CALL assuming following arraydeclaration
int x[5] = {7,4,6,2,3};*
a) minArray(x,5);
b) minArray(x[],10);
c) minArray(x[5],5);
d) minArray(5,x);
Answer:
The answer is "Option a"
Explanation:
Following are the code to this question:
#include <stdio.h>//header file
int minArray(int x[], int n)//defining method minArray that accepts two parameters
{
for(int i=0;i<n;i++)//defining loop for print value
{
printf("%d\n",x[i]);//printf array value
}
}
int main()//defining main method
{
int x[] ={7,4,6,2,3};//defining array that hold values
int n=5;//defining integer variable
minArray(x,5);//calling method minArray
return 0;
}
In this code, a method "minArray" is defined, that accepts two parameters array and an integer variable in its parameter, and in the next step, the for loop is declared, that uses the print method to prints its value.
In the next step, the main method is declared, which declared an array and holds its values and defines an integer variables, and calls the method "minArray".
