The average of 30 numbers is 12.The average of the first 20 of them is 11 and that of the next 9 is 10.The last number is?
50
What is the average of the first ten odd numbers?
Just add them together, and divide the result by 10. (For the average of a larger set of consecutive odd numbers, it's faster to use the formula for an arithmetic series to add them up. Also, the average of such a set is the same as if you just average the first and the last number.)
In set of seven numbers the average of the first four is 15 and the average of the last three is 8 .what is the average of all seven numbers?
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).
How is the last digit of a measurement different from the other digits?
the first number is usually in feet, the last number is in inches. so the last number = 1/12 of the first numbers value.
What is the average of first 2000 odd natural numbers?
The first 2000 odd natural numbers form an arithmetic sequence where the first term is 1 and the common difference is 2. The nth odd number can be expressed as (2n - 1). Therefore, the 2000th odd number is (2 \times 2000 - 1 = 3999). The average of these numbers is given by the formula for the average of an arithmetic sequence, which is ((\text{first term} + \text{last term}) / 2), resulting in ((1 + 3999) / 2 = 2000).

What is the quickest way to add the first 25 odd numbers?
Use the formula for an arithmetic series. That is, take the average of the first and the last number in the series, and multiply by 25. The first number in the series of course is 1; the last number is 1 + 2(24), since there are 24 intervals.

What is the average of seven numbers if the average of the first two is 9 and the average of the last five is 16?
first two add up to 2 x 9 = 18 last 5 add up to 5 x 16 = 80 total of all numbers = 98 Average of all seven numbers = 14
In a set of seven numbers the average of the first four is 15 and the average in the last three is 8 then what is the average in all 7?
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.

Can you define mode?
The Mode is another word for the Average. This means that it is the number that is most likely to occur if you repeat the action that gave you the last numbers. To get the mode, it is pretty simple. You first add all the numbers together, and divide them by the amount of numbers you had to begin with.
How do you find the median in an odd number of data?
List the numbers in order, cross out the first number, the last number, the second first number then the second last number, and so on. The only number left is your median.Here's an Example:Here's the set of numbers.3,9,5,6,1,2,8Place them in order.1,2,3,5,6,8,9Crossing out.1,2,3,5,6,8,91,2,3,5,6,8,91,2,3,5,6,8,9Your answer is revealed!Your final answer is 5.
