Answer:

e) in any circumstance.

Explanation:

It is used in exception handling in Java.Finally clause is used to execute important code such as closing stream ,closing connection to the file etc.

Finally clause is always executed no matter what for every exception handling case.

for ex:-

try{

// some code

}

finally

{

//This code will always be execute.

Extend to also calculate and output the number of 1 gallon cans needed to paint the wal. Hint: Use a math function to round up t

Crank

Answer:

Here is the Python program:

import math #import math to use mathematical functions

height = float(input("Enter wall height (feet): ")) #prompts user to enter wall height and store it in float type variable height

width = float(input("Enter wall width (feet): ")) #prompts user to enter wall width and store it in float type variable width

area = height *width #computes wall area

print('Wall area: {} square feet'.format(round(area))) #displays wall area using round method that returns a floating-point number rounded

sqftPerGallon = 350 #sets sqftPerGallon to 350

paintNeeded = area/ sqftPerGallon #computes needed paint

print("Paint needed: {:.2f} gallons".format(paintNeeded)) #displays computed paint needed up to 2 decimal places

cansNeeded = int(math.ceil(paintNeeded)) #computes needed cans rounding the paintNeeded up to nearest integer using math.ceil

print("Cans needed: {} can(s)".format(cansNeeded)) #displays computed cans needed

colorCostDict = {'red': 35, 'blue': 25, 'green': 23} #creates a dictionary of colors with colors as key and cost as values

color = input("Choose a color to paint the wall: ") #prompts user to enter a color

if color in colorCostDict: #if the chosen color is present in the dictionary

colorCost = colorCostDict.get(color) #then get the color cost from dictionary and stores it into colorCost using get method that returns the value(cost) of the item with the specified key(color)

cost = cansNeeded * colorCost #computes the cost of purchasing paint of specified color per cansNeeded

print("Cost of purchasing {} paint: ${}".format(color,colorCostDict[color])) #displays the real cost of the chosen color paint

print("Cost of purchasing {} paint per {} gallon can(s): ${}".format(color,cansNeeded, cost)) #displays the cost of chosen color paint per cans needed.

Explanation:

The program first prompts the user to enter height and width. Lets say user enter 20 as height and 50 as width so the program becomes:

Wall area computed as:

area = height *width

area = 20 * 50

area = 1000

Hence the output of this part is:

Wall area: 1000 square feet Next program computes paint needed as:

paintNeeded = area/ sqftPerGallon

Since sqftPerGallon = 350 and area= 1000

paintNeeded = 1000 / 350

paintNeeded = 2.86

Hence the output of this part is:

Paint needed: 2.86 gallons

Next program computes cans needed as:

cansNeeded = int(math.ceil(paintNeeded))

This rounds the computed value of paintNeeded i.e. 2.86 up to nearest integer using math.ceil so,

cansNeeded = 3

Hence the output of this part is:

Cans needed: 3 can(s) Next program prompts user to choose a color to paint the wall

Lets say user chooses 'blue'

So the program get the cost corresponding to blue color and multiplies this cost to cans needed to compute the cost of purchasing blue paint per gallon cans. So

cost = cansNeeded * colorCost

cost = 3 * 25

cost = 75

So the output of this part is:

Cost of purchasing blue paint per 3 gallon can(s): $75 The screenshot of the program along with its output is attached.

A set of blocks contains blocks of heights 1,2, and 4 centimeters. Imagine constructing towers of piling blocks of different hei

SashulF [63]

Answer:

In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.

In medical experiments, which group receives placebos?

the experimental group

the control group

both the experimental and control groups

neither the experimental nor control group

Explain the concept of risk management, including risk identification, assessment, and control.

abruzzese [7]

Answer:

Risk management is the technique that is used for managing the risky situation so that security of the system or organization can be maintained. The risk can be reduced by parameters like monitoring the system,alertness, preventive measures etc. There are terms related with the risk management for prevention of the risk such as risk control ,risk identification and risk assessment .

Risk control is the method that is used for calculating the loss or damage experience and then taking the correct measures to reduce the loss and thus, controlling the risk.
Risk assessment is the analyzation of the threats and source of damage/loss that is caused or can be caused by assessing the whole process and functioning.
Risk identification is the technique through which the threat is listed over a document and sorted in accordance with the category of risk, risk response etc.

Write a Java class called BankAccount (Parts of the code is given below), which has two private fields: name (String) and balanc

NemiM [27]

Answer:

Here is the Bank Account class:

public class Bank Account { //class definition

private String name; //private String type field to hold name

private double balance; // private double type field to hold balance

public Bank Account(String name, double balance) { // parameter constructor that takes

//this keyword is used to refer to the data members name and balance and to avoid confusion between name, balance private member fields and constructor arguments name, balance

this.name = name;

this.balance = balance; }

public void deposit(double amount) { //method to deposit amount

balance = balance + amount; } // adds the amount to the account causing the current balance to increase

public void withdraw(double amount) { //method to withdraw amount

balance = balance - amount; } //subtracts the amount causing the current balance to decrease

public String toString() { // to display the name and current balance

return name + " , $" + balance; } } //returns the name and the current balance separated by a comma and dollar
