You've just installed a new video card in a user's Windows workstation. When the system is powered on the screen is blank. You

valentinak56 [21]

After having verified that the video cable is installed correctly we should check to see that the computer's RAM is correctly fastened to the motherboard and functional.

The question states that the video card being installed is new, therefore we can comfortably assume that the card itself is not the issue. Other computer components that can cause a blank screen immediately upon powering on the workstation are:

RAM
Hard drive
Bad video driver.
Monitor input is faulty

however, assuming the installation was performed correctly, it is not likely to be caused by a bad video driver and a faulty monitor input is very improbable given that there are very few ways this can break to begin with.

A bad or missing hard drive may cause this kind of issue because the workstation will not have a windows file to boot. In most cases, this will not cause a completely blank screen without first allowing access to the BIOS.

After having verified that the video cable is installed correctly, the very next thing you should check is if the RAM is installed correctly. This is because the issue explained is exactly what will happen if a workstation attempts to boot without RAM, and also because it is the easiest fix among the possible causes and any troubleshooting should always be performed in order from the easiest fix to the most difficult.

I need help with completing this python code.Complete the Car class by creating an attribute purchase_price (type int) and the m

netineya [11]

Answer:

class Car:

def __init__(self):

self.model_year = 0

# TODO: Declare purchase_price attribute

self.purchase_price = 0

self.current_value = 0

def calc_current_value(self, current_year):

depreciation_rate = 0.15

# Car depreciation formula

car_age = current_year - self.model_year

self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)

# TODO: Define print_info() method to output model_year, purchase_price, and current_value

def print_info(self):

print("Model year: ",self.model_year)

print("Purchase year: ",self.purchase_price)

print("Current value: ",self.current_value)

def main():

year = int(input())

price = int(input())

current_year = int(input())

my_car = Car()

my_car.model_year = year

my_car.purchase_price = price

my_car.calc_current_value(current_year)

my_car.print_info()

if __name__ == "__main__":

main()

Explanation:

The Car class in the python program is used to create a car object instance with class methods model_year, purchase_price, and calc_current_value, which accepts as arguments, year, price and current_year respectively. The main function runs if only the python module is run and interpreted to print out the year and current price of a car object instance defined.

Array Challenge Have the function ArrayChallenge (arr) take the array of numbers stored in arr and return the string true if any

vampirchik [111]

Answer:

The code is given as follows,

Explanation:

Code:

#include <stdio.h>

#include <string.h>

int n; //to store size of array

char* ArrayChallenge(int arr[]) //function returns string true or false

{

int i, j;

int sum = 0;

for(i = 0; i < n; i++)

{

sum = sum + arr[i]; //count sum

}

for(i = 0; i < n; i++)

{

for(j = i+1; j < n; j++) //loop for every two elements in array

{

if(arr[i]*arr[j] > 2*sum) //check if proudct of two elements > 2 times sum

{

printf("\n%d x %d = %d, 2xSum = %d\n", arr[i], arr[j], arr[i]*arr[j], 2*sum);

return "true"; //If proudct of two elements > 2 times sum. return true

}

return "false"; // If proudct of two elements < 2 times sum. return false

}

int main()

{

printf("\nEnter size of array: ");

scanf("%d", &n); //read size of array

int A[n]; //array of size n

printf("\nEnter array elements: ");

int i;

for(i = 0; i < n; i++)

{

scanf("%d", &A[i]); //read array from stdin

}

printf("%s\n",ArrayChallenge(A)); //ccall function and print answer

return 0;

}
