Rounding and Estimating Numbers

3240

126945 .

Inspect the hundred number, '9' in this case.

If the hundred number is '5' or greater , then you add '1' to the thousands number. ( 6 + 1 = 7)

Hence

127,000 is the answer.

NB if the hundreds number is 0 - 4 , then the thousands number remains unvhanges.

e.g. 126, 495 The hundred number is '4' in this case.

Hence to the nearest thousand it is 126,000

1000

600

To the nearest ten, 650

To the nearest hundred, 600

To the nearest tenth, 649.0

To round 34279.38 to the nearest kilometer, you look at the digit in the tenths place, which is 3. Since it is less than 5, you round down. Therefore, 34279.38 rounded to the nearest kilometer is 34279 kilometers.

620

10

It is already to the nearest ten as 3490

0.9999 rounded to the nearest whole number is 1. This is because it is greater than 0.5, which means it rounds up to the next whole number.

To round .8 to the nearest tenth, you look at the digit in the hundredths place, which is 0. Since 0 is less than 5, you round down. Therefore, .8 rounded to the nearest tenth is .8.

It is already rounded to the nearest hundred thousand. You can't round a number to itself.

Round down to zero to the nearest hundred and 32.07 to the nearest hundredth.

what is 60,614 round to the nearest hundred

67 rounded to the nearest hundred is 100.

The Model 20ga 3 mod P fires 20-gauge shotgun shells. Specifically, it is designed to accommodate 3-inch (or 76mm) shells, which are commonly used in various shotgun applications. This size is ideal for hunting and sport shooting, providing a balance of power and manageable recoil.

To find the surface area of a pyramid, first calculate the area of the base, which depends on the shape (e.g., square, triangular). Then, determine the area of the triangular faces by using the formula for the area of a triangle (1/2 * base * height) for each triangular face. Add the area of the base to the sum of the areas of the triangular faces. Round the final result to the nearest whole number for the surface area.

Hand

380 ends with a zero, so it is already rounded to a ten, so it is 380.

The sum of 5.7 cm and 6.2 cm would typically need to be rounded because it is the result of adding two measurements, each with one decimal place. When adding measurements, the result should be rounded to the least precise measurement, which in this case is one decimal place. Thus, the sum of 11.9 cm would remain as is, but if it were to be expressed in a different context requiring rounding, it might be rounded further.

The numbers that round to 645,000 when rounded to the nearest thousand are those from 644,500 to 645,499. This range includes all values starting at 644,500 (inclusive) and going up to 645,499 (inclusive). Any number within this range will round to 645,000 when applying standard rounding rules.

Point estimation is essential because it provides a single, best estimate of a population parameter based on sample data, facilitating decision-making and analysis. It simplifies complex data into a manageable form, allowing researchers and statisticians to make inferences about the larger population. Additionally, point estimates serve as the foundation for further statistical analysis, including hypothesis testing and confidence interval construction, making them crucial in statistical practice.

The number 50 is already a multiple of 10, so when rounded to the nearest ten, it remains 50.

The nearest whole unit of 44 is 44 itself, as it is already a whole number. Whole units refer to integers without any fractional or decimal component, and since 44 fits this definition perfectly, there is no need for rounding.
