Weighted Average
Sum = Sum + first number Sum = Sum + second number Sum = Sum + third number Average = 1/3 x Sum
public int sum(int[] x) {int sum = 0;for(int i : x) {sum += i;}return sum;}public int average(int[] x) {// Note that this returns an int, truncating any decimalreturn sum(x) / x.length;}
You add up all the array elements, then divide by the number of elements. You can use a nested for() loop in Java; inside the inner for() loop, you can both increase a counter (to count how many elements there are), and add to a "sum" variable.
To find the sum and average of array elements in C, you can create a program that initializes an array, calculates the sum of all elements, and then divides the sum by the number of elements to find the average. Here's a simple example: #include <stdio.h> int main() { int arr[] = {1, 2, 3, 4, 5}; int sum = 0; float average; int n = sizeof(arr) / sizeof(arr[0]); for(int i = 0; i < n; i++) { sum += arr[i]; } average = (float)sum / n; printf("Sum: %d\n", sum); printf("Average: %.2f\n", average); return 0; } In this program, we first define an array arr, calculate the sum of all elements in the array using a loop, and then find the average by dividing the sum by the number of elements. Finally, we print out the sum and average values.
the sum of the elements divided by the number of elements is the average
the mean or average of the set
That is called the average or mean.
The average of a set of numbers is the sum of the numbers in the set divided by the number of elements in the set.
The average is the sum of the elements divided by the number of elements In other words, 80%+82.54% then divide the sum by 2.
The sum of a set of data divided by the number of pieces of data is the average or mean.
The sum of a set of numbers divided by the number of addends is the mean average of that set.
The result of this division is the average.(More technically, it is the arithmetic mean.)Exampleheights of some people:63656671the sum of these is 63 + 65 + 66 + 71= 265the number of elements (here, people whose height was measured)= 4So the division is265 / 4= 66.25This is the average height of these four people.
average or mean
The mean is the sum of all elements in the sequence divided by the total number of elements. It is a statistic which represents the expected value of any term in the sequence (the average value).
The mean, or the average.
the average is the sum of the value divided by the number of values
