What program controls the hardware and software in a computer?

___ is an example of a calling statement.

Naddika [18.5K]

Answer:

printf("%f", roi(3, amt));

Explanation:

To call the function, we have to put the function name without return type and if the function have parameter then we have to pass the parameter without data type as well.

Let discuss the options:

Option A: float roi(int, double);

it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.

Option B: printf("%f", roi(3, amt));

print is used to display the result, inside the print it call the function. It is correct way to call the function.

Option C: float roi( int yrs, double rate);

it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.

Option D: float roi( int yrs, double rate)

Same reason as option C.

Therefore, the option B is correct option.

Vivian wants to increase the storage capacity of her computer. Which components should she upgrade?

Nikitich [7]

Answer:

Hard drive

Explanation:

The hard drive is where the operating system, programs and data reside on (unless the data is saved and backed up elsewhere). An older hard drive that uses platters for reading and writing data to it will be slower than a later model solid state device. Newer hard drives have very fast access speeds compared to older units.

nataly862011 [7]

Answer:

The correct answer is option (D) Identify the impact on safety of the property

Explanation:

Solution

In every Business Impact Analysis, the first and the most important step is for the CISO is to identify and estimate the impact of the aftereffects on the business and property of an organization that may be occurred from the disaster.

Physical security is very important, but it is not noticed by most organizations. It is important if you do not want anyone to take away your information or destroy it, in case of natural calamity. the reason could be that, the intruder is doing it for his personal achievement, financial gain,or seeking revenge or when one is taken unaware and becomes a target. If this security is not maintained properly all the safety measures will not be useful once the attacker gets through by gaining physical access.

Example of property can be software, equipment, facilities, company’s assets.

Iven an array temps of double s, containing temperature data, compute the average temperature. Store the average in a variable c

ale4655 [162]

Answer:

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter length of the array:");

int len = in.nextInt();

double [] temps = new double[len];

double avgTem;

int k =0;

double total = 0;

for( k=0; k<temps.length; k++){

System.out.println("Enter values for the array");

temps[k]=in.nextDouble();

}

System.out.println("The Arrays contains the following values");

System.out.println(Arrays.toString(temps));

// Computing the average of the values

for(k=0; k<temps.length; k++){

total = total+temps[k];

}

avgTem = total/(temps.length);

System.out.println("The average Temperature is: "+avgTem);

}

Explanation:

Using Java programming language
Import the Scanner class to receive user input
Prompt User for the length of the Array, receive and store in a variable len;
Declare a new double array of size len double [] temps = new double[len];
Using a for loop, continually prompt user to enter values into the array
Display the values of the array using Java's Arrays.toString method
Use another for loop to add up all the elements in the arraay and store in the variable called total
Outside the second for loop calculate the average avgTem = total/(temps.length);
Display the average temp.
