Answer:

In Python:

def returnERA(runs,total):

ERA = runs *9/total

return ERA

Explanation:

This defines the function. It receives the number of runs and the total runs as its parameters

def returnERA(runs,total):

This calculates the ERA

ERA = runs *9/total

This returns the ERA

return ERA

Write a program to calculate the great circle distance between two points on the surface of a sphere. If p1(x1, y1) and p2(x2,y2

Tamiku [17]

Answer:

import java.lang.*;

public class distance { public static double distance(double latitude1,

double latitude2, double longitude1,

double longitude2)

{

// Convert Latitude and Longitude to Radians

longitude1 = Math.toRadians(longitude1);

longitude2 = Math.toRadians(longitude2);

latitude1 = Math.toRadians(latitude1);

latitude2 = Math.toRadians(latitude2);

double d_longitude = longitude2 - longitude1;

double d_latitude = latitude2 - latitude1;

double a = Math.pow(Math.sin(d_latitude / 2), 2)

+ Math.cos(latitude1) * Math.cos(latitude2)

* Math.pow(Math.sin(d_longitude / 2),2);

double val = 2 * Math.asin(Math.sqrt(a));

// Radius of earth in kilometers is 6371

double earth_radius = 6371;

// Calculate and return the distance

return(val * earth_radius);

}

// Main Method

public static void main(String[] args)

{

double latitude1 = 67.32055555555556;

double latitude2 = 83.31861111111111;

double longitude1 = -1.7217899;

double longitude2 = -1.6567799;

System.out.println(distance(latitude1, latitude2,

longitude1, longitude2) + " K.M");

}

Explanation:

This program is implemented in Java programming language

The formula for the shortest distance between two points on the earth is:

Distance = 3963.0 * arccos[(sin(lat1) * sin(lat2)) + cos(lat1) * cos(lat2) * cos(long2 – long1)]

The latitude and longitude of the two points must be known

The latitude and longitude are converted into radians using built in methods in java.

Take value for the radius of the earth in Kilometers 6371;

Note that a seperate method has been created to calculate the distance

In the driver method (main), values for latitude and logitudes for both places have been hard-corded, then the method distance is called and passed those values

Note also that the distance has been calculated in Kilometers

If someone said to you, “Pseudocode is a waste of time! It’s just more work because you end up writing the same program twice,”

myrzilka [38]

Answer:

It allows the designer to focus on main logic without being distracted by programming languages syntax.

* Since it is language independent, it can be translated to any computer language code.

* It allows designer to express logic in plain natural language.

* It is easier to write actual code using pseudocode.

* Unlike algorithms, pseudocodes are concise so pseudocodes are more readable and easier to modify.

should variables that contain numbers always be declared as integer or floating-point data types? why or why not? name potential

Stells [14]

No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.

It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.

Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.

Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.

In Python int, float, and complex are the data types used to declare number type variables.

SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.

To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.

JavaScript uses a single data type called 'number' to declare numbers.

In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.

So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
