Answer:
A. 9
Explanation:
the symbol (**) means to put to the exponent to. So in this case, 3**2 is the same as 3^2 or 3 squared, 3x3=9. So that is the answer.

Answer:
A. Management of entry and exit code is managed by OpenMP library reducing the possibility of programming errors
Explanation:
This is a multiple choice question and this is the answer because:
1. OpenMp is inclusive of an APL/compiler directives:
2. any code which follows #pragma omp parallel is a parallel region and it is performed by large number of threads that are same as the number of processing cores that are in the system.
3. The critical-section compiler directive acts more like a binary semaphore or mutex lock,it makes sure that only one thread is active in the critical section at the same time.
g Create a Java program that takes input of a list of integers from the user, stores them into an array and then finally uses the array contents to output the list of integers in reverse. The user's input begins with the number of integers to be stored in the array. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers.Create a Java program Ex: If the input is: 8 5 2 3 4 10 6 8 9
Answers
Answer:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int arraylent;
Scanner input = new Scanner(System.in);
System.out.print("Array Length: ");
arraylent= input.nextInt();
int[] myarray = new int[arraylent];
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);
}
}
Explanation:
This declares the length of the array
int arraylent;
This next two lines prompt and get the array length i.e. number of input
System.out.print("Array Length: ");
arraylent= input.nextInt();
This declares the array as type integer. And the length of the array is gotten from the user input
int[] myarray = new int[arraylent];
This gets the items of the array
for(int i = 0; i<arraylent;i++)
myarray[i] = input.nextInt();
This reverse and prints the array
for(int i = arraylent-1; i>=0;i--)
System.out.println(myarray[i]);

The numbers that should be stored in miles are240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, and 192.3. The numbers should bestored in gallons are 10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, and 8.4.
Answers
Answer:
#include <iostream>
using namespace std;
int main(){
double miles[10] = {240.5, 300, 189.6, 310.6, 280.7, 206.9, 199.4, 160.3, 177.4, 192.3};
double gallons[10] = {10.3, 15.6, 8.7, 14, 16.3, 15.7, 14.9, 10.7, 8.3, 8.4};

Explanation:
The C++ source code declares three arrays miles, gallons and mpg with an array length of 10. The gallons and miles arrays are assigned 10 array items each and they are used to push values to the mpg array in the for loop statement. The result of each item in the mpg array is displayed on the screen.

Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings
Sample game board at the arcade GAME COMPLETION TIME (in minutes) PAYOUT RATE Pac-man 90 400 Mortal Kombat 10 30 Super Tetris 25 100 Pump it Up 10 40 Street Fighter II 90 450 Speed Racer 10 40
An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.
Question:
Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money?.
Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?
Input Explanation
The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
The games board may change but the store still closes in 120 minutes.
Input

Pac-man,80,400
Mortal Kombat,10,30
Super Tetris,25,100
Pump it Up,10,40
Street Fighter II,90,450

PLS HELP ASAP- Select the correct text in the passage.
Which concept explained in the paragraph below means that data always remains consistent?
Specific programs have some tasks that a computer must perform in parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters. In such cases, a separate thread of execution handles each separate task. You can think of a thread as a sequence of instructions that computers can manage independently.
It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of information. For instance, if multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencies by using locks. A thread puts a lock on shared data, and releases this lock only after completing its operations.

I am having trouble with doing this code on Python:Develop the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.Ex: If the input is:2011 18000 2018where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770Note: print_info() should use three spaces for indentation.
Answers
Answer:
class Car:
def __init__(self, model_year, purchase_price):
self.model_year = model_year
self.purchase_price = purchase_price
self.current_year = 0
self.current_value = 0
def set_current_year(self, year):
self.current_year = year
def calc_current_value(self, current_year):
if self.current_year == 0:
return "Must first input the current year"
depreciation_rate = 0.15
car_age = current_year - self.model_year
self.current_value = round(self.purchase_price - (car_age * (self.purchase_price * 0.15)))
def print_info(self):
print("Car's information:")
print(f"Model year: {self.model_year}")
print(f"Purchase price: {self.purchase_price}")
if self.current_value > 0:
print(f"Current value: {self.current_value}")
else:
print("Current value: Unknown")
Explanation:
The python program above defines the class "Car" that accepts the model year and purchase price of an instance. The class has a set method for the current year variable that is used to calculate and update the current value variable of the object. The print_info method prints the car model year, purchase price and its current value after nth years.

The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?
Answers
Answer:
P₂ = 0.5 W
Explanation:
It is given that,
The attenuation of a signal is -10 dB.
We need to find the final signal power if it was originally 5 W.
Using attenuation for signal :
[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]
Put dB = -10, P₁ = 5 W
Put all the values,
[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]
So, the final signal power is 0.5 W.
The final signal power if it was originally 5W is; 0.5 W
Signal PowerWe are given;
Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 WFormula for attenuation signal is;
dB = 10log_10_ (P2/P1)
Where P2 is final signal power
Thus;
-10 = 10log_10_(P2/5)
-10/-10 = log_10_(P2/5)
-1 = log_10_(P2/5)
0.1 = P2/5
P2 = 0.1 × 5
P2 = 0.5 W

System.out.print("Length of array: ");
This gets the length of the arrau
int len = input.nextInt();
This declares the array as integer

What would be the appropriate ownerships and permissions for both directory games and the file ourgames.txt look like

The directory games and the ourgames.txt file are owned by max who has read, write and execute permissions for both, where the 'd' in the first column represents the directory. The gameplayers group has read and execute permissions represented by the 'r' and 'x' letters. The other group is the third section with just dashes which means no permission is granted for the file.
