The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125 The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100 → the excluded number is 125 - 100 = 25. Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.
A signed number representing a change in average indicates the direction and magnitude of that change. A positive signed number suggests an increase in the average, while a negative signed number indicates a decrease. For example, if the average temperature rises from 20°C to 25°C, the change would be +5°C. Conversely, if the average drops from 20°C to 15°C, the change would be -5°C.
Add the values you wish to average, and divide by the number of values. For example: If I wanted to find the average of 1,2,3,4,5: (1+2+3+4+5)/(5)=3
The same number that is between 3 and 8 is 5. This is because 5 is the average or mean of 3 and 8. To find the average of two numbers, you add them together and then divide by 2. In this case, (3 + 8) / 2 = 11 / 2 = 5.
To write pseudocode that accepts five numbers and displays their sum and average, you can follow these steps: Initialize a variable sum to 0. Loop five times to accept input for each number, adding each to sum. After the loop, calculate the average by dividing sum by 5. Display both the sum and the average. Here’s a simple representation: BEGIN sum = 0 FOR i FROM 1 TO 5 DO INPUT number sum = sum + number END FOR average = sum / 5 OUTPUT "Sum: ", sum OUTPUT "Average: ", average END
It is: 4+7+5+4+5 = 25/5 = 5 which is the average number
If the average is 10 then 15 is 5 above average.
If the average of 5 numbers is 23 and the range is 10, what are the 5 numbers?
5-8
The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125 The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100 → the excluded number is 125 - 100 = 25. Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.
Since there is only one number, the average is the number itself! It is 132/10 = 66/5
3, 5, and 7 are three prime numbers whose average is 5.

If the average of 5 numbers is 86, then their sum is 430.If the average of 6 numbers is 84, then their sum is 504.The sum grew by (504 - 430) = 74, so that was the 6th number.
The average number of toes for an American is 10, as most people have 10 toes (5 on each foot).
3, 5, and 7 are three prime numbers whose average is 5.
