Python can be used to implement central of tendencies such as mean, median and mode using the statistic module

The program in Python, where comments are used to explain each line is as follows:

#This imports the statistics module

import statistics

#This defines the function that calculates the mode

def calcMode(myList):

#This prints the mode

print(statistics.multimode(myList))

#This defines the function that calculates the median

def calcMedian(myList):

#This prints the median

print(statistics.median(myList))

#The main method begins here

#This initializes the list

myList = []

#The following iteration gets input for the list

for i in range(10):

myList.append(int(input()))

#This calls the calcMode method

calcMode(myList)

#This calls the calcMedian method

calcMedian(myList)

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:

sdas [7]

Answer:

The modified program in Python is as follows:

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

wall_width = int(input('Enter wall width (feet):\n'))

area = wall_height*wall_width

print('Wall area:',area,'square feet')

paint_needed = area/350.0

print('Paint needed: {:.2f} gallons'.format(paint_needed))

print('Cans needed:',round(paint_needed),'can(s)')

color = input("Choose a color to paint the wall: ")

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Explanation:

The italicized are given from the question [unchanged]

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

This gets input for width

wall_width = int(input('Enter wall width (feet):\n'))

Calculate the wall area

area = wall_height*wall_width

Print the calculated wall area

print('Wall area:',area,'square feet')

Calculate the amount of paint needed

paint_needed = area/350.0

Print the amount of paint needed to 2 decimal places

print('Paint needed: {:.2f} gallons'.format(paint_needed))

Print the amount of can needed to nearest integer

print('Cans needed:',round(paint_needed),'can(s)')

Prompt user for color of paint [here, we assume the user input is correct]

color = input("Choose a color to paint the wall: ")

Prints the corresponding amount for the color

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Write a Java program that reads an 8-bit binary number from the keyboard as a string and then converts it into decimal. For exam

cestrela7 [59]

Answer:

public class Brainly

{

public static void main(String[] args)

{

BinaryConverter conv = new BinaryConverter();

String binStr = "01001101";

System.out.print(binStr + " in decimal is "+conv.BinToDec(binStr));

}

public class BinaryConverter

{

public int BinToDec(String binStr)

{

int d = 0;

while(binStr.length() > 0)

{

d = (d << 1) + ((binStr.charAt(0) == '1') ? 1: 0);

binStr = binStr.substring(1);

}

return d;

}

Explanation:

The program "eats" the string from left to right, and builds up the integer representation in variable "d" on the go. While there are digits left, it shifts the previous result to the left and sets the least signficant bit to 1 only if the corresponding string character is a 1.
