How do you find the sum of a set of numbers?
To find the sum of a set of numbers, you can use this formula: ∑ = (x)(x+1)/2 That is..... The sum = (The number of samples)(The number of samples + 1)/2 Example: What is the sum of all numbers between 500 and 1000? Assuming that we do not include 500 or 1000 in our answer, we have 498 numbers to add up. Let's put that into the formula.... ∑ = (498)(498+1)/2 ∑ = (498)(499)/2 ∑ = (248,502)/2 ∑ = 124,251 The Answer is 124,251
What is the estimate of the sum of 14.30 143.08 and 19.74?
Well, the idea is to round each number, then add them. This basically allows you to do estimated calculations in your head, whereas the complete operation would require (for most people) to use pencil and paper, or a calculator. Since there are different ways to round numbers, the answers may vary. I would suggest, in this case, to round each number to the nearest multiple of 10.
What is the sum of the first 22 odd numbers?
The sum of a sequence is given by sum = n/2(2a + (n-1)d) where: n = how many a = first number of sequence d = difference between terms of sequence. For the first 22 odd numbers these are: n = 22 a = 1 d = 2 → sum = 22/2(2×1 + (22 - 1)×2)) = 22² = 484 The sum of the first n odd numbers is always n²: sum = n/2(2×1 + (n-1)2) = n/2(1 + (n-1))×2 = n(n) = n²
How do you use rounding to estimate a product?
You round the two numbers you are multiplying and try it. Lets use 16 and 13 and round to the nearest ten. We would round 16 to 20, and 13 to 10. Then we multiply 20 and 10 and get 200. So the answer would be around 200. The actual answer is 208 by the way.
What 5 numbers will equal 40?
To find five numbers that equal 40, you can use any combination of numbers that add up to 40. For example, you could use 8, 8, 8, 8, and 8. Another combination could be 10, 10, 5, 5, and 10. As long as the sum of the five numbers equals 40, there are multiple possibilities for the specific numbers you can use.
What numbers would you use to estimate the sum of 17.23 and 3.71?
17 and 4: sum is 21.
What numbers would you use to estimate the sum of 38 and 51?
I would use 40 for the 38 and 50 for the 51. 90 would be my estimate.
When all addends are about the same you can use to estimate their sum.?
you can use whole numbers
Which pair of compatible numbers would be best to estimate the sum of 249 and 752?
You could use 250 and 750.
What numbers would you use to estimate the sum of 23 and 65?
If I had to, I would use 20 and 70.
When would a scientist use estimate numbers?
When working with very large numbers or very small numbers and they would use a system of numeracy known as scientific notation.
Use the numbers 5678 to write an equation with the largest possible sum?
use the numbers 5,6,7,8 to write an equation with the largest possible equation
What compatible numbers would you use to estimate 129.4 divided by 23?
5.6261
Would you use rounding or compatible numbers to estimate the quotient of 46.8366.404?
50.0000.000
What six numbers average out to 4?
To find six numbers that average out to 4, we can use the formula for calculating averages: Average = (Sum of all numbers) / (Total number of numbers). Since we have six numbers, the sum of all numbers must be 6 * 4 = 24. To evenly distribute this sum, we can choose the numbers 3, 3, 4, 4, 5, and 5. Their sum is 24, and when divided by 6, the average is indeed 4.
A method used to estimate a sum when all addends are close to the same value?
Hm well you can use whole numbers. Now my boy do you get it? Get that brain working!
How do you use comparable numbers to estimate multiplication?
the answer is yes because you can estimate any numbers
