Using the merge method of the Map interface, which statement correctly updates the salesTotalByDept map of type Map to update the sales total for a dept by an integer sales value? Question 3 options: salesTotalByDept.merge(dept, sales,(d,s) -> s + 1); sales.merge(salesTotalByDept, dept, (d,s) -> s + sales); dept.merge(salesTotalByDept, sales, (d,s) -> s + sales); salesTotalByDept.merge(dept, sales, (d,s) -> s + sales);

Answers

Answer 1

Answer:

salesTotalByDept.merge(dept, sales, (d,s) -> s + sales);

Explanation:

In the above statement merge() method is being used which updates the salesTotalByDept map of type Map to update the sales total for a dept by an integer sales value.

Here dept and sales both are used and passed as a parameter to merge() method because salesTotalByDept can be update if both the information about sales and department are provided.

Map.merge() method is used to place new value under the given key if the key does not correspond to any value, or is used to update existing key with a given value.

Today when Dylan turned on his computer, he noticed that the monitor was very dim. He could still see the desktop icon and text. He turned the brightness all the way up, but that did not correct the issue. Dylan also checked to make sure the Power Options brightness was not turned down, causing the screen to go dim. He connected a different monitor, and the screen was fine. What caused the screen to be very dim

Answers

Answer:

Monitor backlighting

Explanation:

Dylan haven done some troubleshooting on his computer to find out what the problem was but couldn't restore its brightness.

It then means that the Monitor backlighting caused the screen to be very dim.

The Monitor backlighting is bad or faulty.

Answer:

The Liquid Crystal Display lighting of the monitor is most likely faulty.

Explanation:

By connecting his computer to an external monitor and observing that the brightness of the external monitor was fine, we can deduce that the dimness of his computer was not a software issue but that of hardware. That is the computer monitor itself.  

The most probable reason for the dimness of his computer monitor would e an hardware issue occasioned by a faulty LCD - Liquid Crystal Display or LED, the back light powering the LCD of his computer computer monitor would have to be replaced by a qualified technician.

When Tim Berners-Lee developed the first specifications, protocols, and tools for the World Wide Web in 1993, his employers at CERN chose to make the underlying code publicly available on a royalty-free basis so that anyone who ever wanted to use it or build upon it could do so without having to pay any licensing fees to CERN or ask for CERN's permission.
Which of the following best describes the reasons for this decision?

a. CERN did not recognize the full potential of the World Wide Web and did not think it was worth investing any more of its own resources into its further development.
b. By offering the Word Wide Web as a freely available alternative, CERN hoped to discourage people from using America Online, CERN's biggest competitor for online communication services.
c. Had the technology been proprietary (i.e., closed and privately licensed), it would likely not have become as popular as it has or have been adopted by so many users and institutions across the globe.
d. Because Tim Berners-Lee did not ask his employers for permission before using CERN resources to develop the World Wide Web, as punishment, he was required to give the technology away for free and sacrifice the millions of dollars he could have personally made by selling his idea for a profit.

Answers

Answer:

c.

Explanation:

People trust open-source software - if they can see how it works and understand it, they can help improve it and build applications using it. If these protocols were not publicly available - then nobody would have implemented services using them - so nobody would be adopting it.

A person is eligible to be a US senator if they are at least 30 years oldand have been a US citizen for at least 9 years. To be a US representativethese numbers are 25 and 7, respectively. Write a program that accepts aperson's age and years of citizenship as input and outputs their eligibilityfor the Senate and House.

Answers

Answer:

import java.util.Scanner;

public class num1 {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       //Prompt for the person's age

       System.out.println("What is your age");

       int age = in.nextInt();

       //Prompt for the person's years of citizenship

       System.out.println("What is your years of citizenship");

       int yearsCitizenship = in.nextInt();

       if(age >= 30 && yearsCitizenship >= 9){

           System.out.println("You are Eligible to be a US senator");

       }

       if(age >= 25 && yearsCitizenship >= 7){

           System.out.println("You are Eligible to be a US representative");

       }

   }

}

Explanation:

Using Java Programming language

The scanner class is used to receive and store the persons age and year of citizenship

The first if statement is used to test if the age >= 30 and citizenship>=9 If this is true, it prints out You are Eligible to be a US senator. You are Eligible to be a US representative. Note that if the second condition is true, then the first is also true because to be eligible for senatorial also means you also meet the requirments for representative position

Answer:

age = int(input("Your age: "))

citizen = int(input("Years of being a US citizen: "))

if age >= 30 && citizen >= 9:

   print("You are eligible to US representative and a US senator")

elif age >= 25 && citizen >= 7:

   print("You are eligible to be a US representative")

else:

   print("You are not eligible to be a US representative or US senator")

Explanation:

Ask the user for its age, and years of citizenship

Check the both inputs:

If age is greater than or equal to 30 and citizen is greater than or equal to 9, it means the person is eligible for US representative and a US senator

If age is greater than or equal to 25 and citizen is greater than or equal to 7, it means the person is eligible for US representative

In any other case, the person is not eligible

Suppose that for every 10,000 lightning strikes, meteorologists can predict that one will hit a building and cause damage. If a massive thunderstorm sweeps through your state today, and 5 million lightning strikes are recorded, how many buildings were probably hit by lightning?

Answers

Answer:

500

Explanation:

[tex]\frac{1}{10000}*5000000 = 500[/tex]

The meteorologist predicts the building will hit if the supermassive thunderstorm sweeps through. Thus about 500 buildings will e hit by lightning.

Who is a meteorologist :

A meteorologist is a scientist who studies the works of wreaths atmospheric phenomenon and makes use of the mathematical model and his knowledge to make daily weather forecasts and they work in government agencies, consulting, and research services.

As per the 10,000 lightning stakes can be predicted ad about 5 million have already been recorded thus one stricke divided by 10,000 predictions and multiplied by 500,00,00 records gives us 500 hits.

A user brings in a smartphone for repair. The device is unable to send/receive calls or connect to WiFi. All applications on the device are working unless they require connectivity. Which of the following is MOST likely causing the problem?
a. Airplane mode
b. Tethering
c. Disabled hotspot
d. VPN

Answers

Answer:

I believe it would be airplane mode:)

Explanation:

A VPN connects you to wifi in a another part of the country or world, hotspot connects others to your celluar when on, tethering is when internet connects to your phone. usually costs $ to do. airplane mode is the only thing left.

Have a great day (or night!)

The issue with the smartphone likely stems from airplane mode being enabled, which turns off all wireless communications. The user should check and disable airplane mode if necessary, and if the problem persists, further troubleshooting steps like restarting the phone and checking VPN settings are recommended.

If a smartphone is unable to send/receive calls or connect to WiFi but operates normally otherwise, the most likely cause is airplane mode. When airplane mode is enabled, all wireless communications, including mobile network, WiFi, and Bluetooth, are turned off to prevent interference with aircraft systems or during certain medical procedures. This would prevent the phone from performing any functions that require connectivity like making calls or connecting to the internet. The user should check to ensure that airplane mode is not activated. If airplane mode is not the culprit, the issue might be more complex, potentially involving hardware or deeper software issues, and further troubleshooting steps would include things like restarting the phone, turning off WiFi, and checking for any active VPN connections which could also cause connectivity problems.

The Fibonacci sequence starts 1, 1, 2, 3, 5, 8, .. . . Each number in the se-quence (after the first two) is the sum of the previous two. Write a pro-gram that computes and outputs the nth Fibonacci number, where n is avalue entered by the user.

Answers

Answer:

value=int(input("Enter the number up-to the user wants the Fibonacci series: "))

a=0

b=1

c=1

for x in range(value):

   print(c,end=" ")

   c=a+b

   a=b

   b=c

Output :

If the user input 5, then the output is "1 1 2 3 5".If the user input 10, then the output is "1 1 2 3 5 8 13 21 34 55".

Explanation:

The above defined a python program which is used for the Fibonacci series.The first line of the program is used to instruct the user and take the input from the user. Then the for loop executes up-to that range value.Then in the for-loop, the two variable needs to store the current value and previous value which is used to give the series after addition.

The stack pop operation

What is some iterative programming structure uses?

Answers

Answer

Often in an algorithm, a group of statements needs to be executed again and again until a certain condition is met, this is where we find the need for iteration.

The repeated execution of some groups of code statements in a program is called iteration.

In iteration control structures, a statement or block is executed until the program reaches a certain state, or operations have been applied to every element of a collection. This is usually expressed with keywords such as while, repeat, for, or do..until.

The basic attribute of an iteration control structure is to be able to repeat some lines of code. The visual display of iteration creates a circular loop pattern when flowcharted, thus the word “loop” is associated with iteration control structures. Iteration can be accomplished with test before loops, test after loops, and counting loops. A question using Boolean concepts usually controls how often the loop will execute.

Applications of Iteration

Iteration methodology has various applications in the programming world

Problem-solving in arrays, vectors, lists, strings, etc. Problem-solving using Stack, Queue and Priority Queue Bottom-up implementation of Dynamic Programming Implementation of greedy algorithms BFS traversal of tree and graph Problem-solving using Hash Table and BST Iterative Implementation of recursive code using stack
