Hey there, this isn't really my part of town, I'm what you call a math freak, but here.

In relation to computer processors, a core is the processing kinda like a brain we ppl have, this is the unit that receives instructions and performs calculations, or actions, based on those instructions like when you click something. A set of instructions can allow a software program perform a specific function. Processors can have a single core or multiple cores that do many different things.
Hopefully i helped you, please mark brainly if possible.

Answer:

Explanation:

( n cards are there initially )

we pick out the first card in random it takes n-1 comparisons to figure out

its Equivalence card - n-1 steps

Two cards have been eliminated ( this leaves us with 2 and n-2 cards)

we pick out the 2nd card in random it takes n-3 comparisons to figure out

its Equivalence card - n-3 steps

we continue to do this.. till all cards are exhausted ( leaves us with 2

and n-4 cards again)

the last comparison will

have

- n-(n-3)

the sum of all these steps - (n-1) + (n-3) + (n-5) + .........+

(n-(n-3))

if you draw this in the form of a tree.

n - n

n-2 - n

n-4 - n-2

n-6 - n-4

n-8 - n- 6

the height of the tree will be log n , sum @ each level is at most n

Which US electronics company was the pioneer in home video game consoles

drek231 [11]

This is a list of home video game consoles in chronological order, which includes the very first home video game consoles ever created, such as first generation Pong consoles, from the first ever cartridge console Odyssey, ranging from the major video game companies such as Magnavox, Atari, Nintendo, Sega, NEC, 3DO, SNK, Sony, Microsoft to secondary market consoles.

The list is divided into eras which are named based on the dominant console type of the era, though not all consoles of those eras are of the same type. Some eras are referred to based on how many bits a major console could process. The "128-bit era" (sixth generation) was the final era in which this practice was widespread.[citation needed]

This list does not include other types of video game consoles such as handheld game consoles, which are usually of lower computational power than home consoles due to their smaller size, microconsoles, which are usually low-cost Android-based devices that rely on downloading, or dedicated consoles which have games built in and do not use any form of physical media. Consoles have been redesigned from time to time to improve their market appeal. Redesigned models are not listed on their own.

Brian has created the following selection sort class in Java. In which line is the index of the smallest value returned? In whic

katen-ka-za [31]

Answer:

Explanation:

Since there are no line numbers in this question I will start counting from public class SelectionSort{ as line 1 and so on, as well as provide the code on that line.

The index of the smallest value is returned on line 8 where it says return min which shouldn't have any spaces and should be return minPosition;

The input array is given as an argument at the beginning of the function on line 2 where it says private static int positionMin (int] vals, int startPosition) {, as the variable vals.

This input array is also used as an argument on line 10 where it says Position; private static void swap(int] vals, int firstPosition, int secondPosition) and line 15 where it says vals[secondPosition] temp return public static void selSort(int| vals) {

Given an array as follows

slava [35]

Answer:

1) Method calcTotal:

public static long calcTotal(long [][] arr2D){
long total = 0;
for(int i = 0; i < arr2D.length; i++ )
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
}
}
return total;
}

Explanation:

Line 1: Define a public method calcTotal and this method accept a two-dimensional array

Line 2: Declare a variable, total, and initialize it with zero.

Line 4: An outer for-loop to iterate through every rows of the two-dimensional array

Line 6: An inner for-loop to iterate though every columns within a particular row.

Line 8: Within the inner for-loop, use current row and column index, i and j, to repeatedly extract the value of each element in the array and add it to the variable total.

Line 12: Return the final total of all the element values as an output

Answer:

2) Method calcAverage:

public static double calcAverage(long [][] arr2D){
double total = 0;
int count = 0;
for(int i = 0; i < arr2D.length; i++ )
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
count++;
}
}
double average = total / count;
return average;
}

Explanation:

The code in method calcAverage is quite similar to method calcTotal. We just need to add a counter and use that counter as a divisor of total values to obtain an average.

Line 4: Declare a variable, count, as an counter and initialize it to zero.

Line 11: Whenever an element of the 2D array is added to the total, the count is incremented by one. By doing so, we can get the total number of elements that exist in the array.

Line 16: Use the count as a divisor to the total to get average

Line 18: Return the average of all the values in the array as an output.

Answer:

3) calcRowAverage:

public static double calcRowAverage(long [][] arr2D, int row){
double total = 0;
int count = 0;
for(int i = 0; i < arr2D.length; i++ )
{
if(i == row)
{
for(int j = 0; j < arr2D[i].length; j++)
{
total = total + arr2D[i][j];
count++;
}
}
}
double average = total / count;
return average;
}

Explanation:

By using method calcAverage as a foundation, add one more parameter, row, in the method calcRowAverage. The row number is used as an conditional checking criteria to ensure only that particular row of elements will be summed up and divided by the counter to get an average of that row.

Line 1: Add one more parameter, row,

Line 8-15: Check if current row index, i, is equal to the target row number, proceed to sum up the array element in that particular row and increment the counter.
