An exact number is 2, or 4, or 5345. Something that we have counted, or that we know exactly.
We have two apples. There are four people in the room.
A measurement, however, always has some degree of uncertainty. We can say that the line is 2 inches long. However, if we used a plastic ruler, the line may actually be 1.98 inches long, or 2.03 inches long, and we wouldn't be able to tell the difference with our instrument (the ruler).
If we used a micrometer to measure the line, and the micrometer told us that the line was 4.35 cm long, then we would have to determine the precision (how correctly we can be certain of the results from the micrometer). The micrometer may be precise to within 5/1000 cm, or .005 cm. If that's true, then we're pretty sure that the line is between 4.345 cm and 4.355 cm, but we cannot be sure where in that range the actual length of the line falls.

What number lies between one third and one fifth?
A whole lot of numbers! The simplest example would probably be 0.3. To be exact, there exist uncountably infinitely many real numbers between any 2 distinct real numbers.
Why is precise measurements important?
It is important because PRECISE means exact, and exact measurements are important because it tells you the actual measurement of an object, other than to tell you an estimate, not knowing the exact measurement of that object
What are advantages and disadvantages of representing a relationship between variables in a table?
advantages: its easier to figure out or look at exact numbers disadvantages: its harder to see the change between intervals
What number is between 0.1 and 0.24?
0.125 is one of many numbers that are between 0.1 (also called 0.10) and 0.24. If you are looking for the number in the exact center between the two (the average), then it would be 0.17.
Desccride a situation in which estimating mixed numbers would not be good idea?
Estimating mixed numbers may not be a good idea when precise measurements are crucial, such as in scientific experiments or architectural designs. In these situations, even small errors in estimation could lead to significant inaccuracies. Additionally, when dealing with financial transactions or recipe measurements, estimating mixed numbers could result in incorrect amounts, leading to financial discrepancies or unsatisfactory outcomes. Therefore, it is important to use exact calculations for accurate results in such scenarios.
What is difference between measurement and estimation?
The difference between a measurement and an estimation is that a measurement is an exact data while an estimation is a guess as to what something may measure. For example, you can use a ruler to get the exact measurements of a piece of paper. However, if you don't have a ruler, you can make an educated guess as to what the paper's length and width measurements may be.
What is the difference between direct and indirect measurement?
Direct is an exact measurement and indirect is an estimate.

What is the difference between biome and life zone?
there is no difference they both mean the exact same thing =)
Difference between frequency table and relative frequency table?
Frequancy Tables only use whole numbers while relative frequency tables use exact percentages or decimals.
