Oh, what a happy little math problem we have here! To find the average of all seven numbers, we can add the averages of the first four numbers and the last three numbers together, then divide by 7. So, (15 x 4 + 8 x 3) / 7 = 11. The average of all seven numbers is 11.
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.
Oh, dude, math time! So, the sum of the first four numbers is 15 x 4 = 60, and the sum of the last three numbers is 8 x 3 = 24. Add those together, you get 60 + 24 = 84. To find the average of all seven numbers, you divide 84 by 7, which gives you an average of 12. So, the average of all seven numbers is 12. Math wizardry!
The 12th odd number.
To calculate the average of two numbers, add them together, and divide the result by 2. (For the average of three numbers, you add up the three numbers, and divide by three, etc.) The average is (5000 + 7000)/2 = 6000
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
48
There are three whole numbers berween three and seven. They are four, five and six.
12
The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.
The 12th odd number.
To calculate the average of two numbers, add them together, and divide the result by 2. (For the average of three numbers, you add up the three numbers, and divide by three, etc.) The average is (5000 + 7000)/2 = 6000
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
125, 126 and 127.
3, 5, and 7 are three prime numbers whose average is 5.
Yes. For example, the average of 5, 7, and 9 is 7.
The average of the numbers 51, 52, and 56 is 53. To get the average you would add all three numbers and then divide by three.
The first three prime numbers are 2,3 and 5.
3, 5, and 7 are three prime numbers whose average is 5.
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
