The average of the first ten prime numbers is 12.9.
To find the average of the three numbers, first calculate the third number by subtracting the sum of the first two from the total sum: (456 - (121.3 + 175.4) = 456 - 296.7 = 159.3). Next, add all three numbers: (121.3 + 175.4 + 159.3 = 456). Finally, divide the total by 3 to find the average: (456 \div 3 = 152). Thus, the average of the three numbers is 152.
To find the average of all seven numbers, we first calculate the total for the first four numbers. Since their average is 15, their total is (4 \times 15 = 60). For the last three numbers, with an average of 8, their total is (3 \times 8 = 24). Therefore, the total of all seven numbers is (60 + 24 = 84), and the average of all seven numbers is ( \frac{84}{7} = 12).
To get the simple average of a series of numbers, you add the numbers up and divide by however many numbers there were. For example, the average of 2, 3 and 4 is the sum of the numbers (which adds up to 9) divided by 3 (because there are three numbers). So the average is 9/3 = 3.
3 x 5 x 5 = 75

18 is composite. 18 = 2 * 3 * 3 = 2 * 32
average of first five prime numbers = 5.6 first five prime numbers = 2, 3, 5, 7, 11average = sum of first prime numbers/5= (2 + 3 + 5 + 7 + 11)/5= 28/5= 5.6

5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.

The average of several numbers is the sum of the numbers divided by the quantity of the numbers. (3 + 3.5 + 6) ÷ 3 = 4 1/6

To find the average of all seven numbers, we can use the formula for the average: (sum of all numbers) / (total number of numbers). Given that the average of the first four numbers is 15, the sum of the first four numbers is 15 * 4 = 60. Similarly, the sum of the last three numbers is 8 * 3 = 24. Therefore, the sum of all seven numbers is 60 + 24 = 84. Finally, the average of all seven numbers is 84 / 7 = 12.
Yes. For example, the average of the numbers 1, 2, and 3 is 2. 1+2+3=6 6/3=2
