Is number of purchase made in a month a discrete or continuous variable?
Discrete as you cannot have half a purchase and do not need to use a measuring device.- Discrete : Information that is counted or measured in distinct separate units eg. kids in a family, books on a shelf- Continuous : Information measured along a continuous scale, requiring a measuring device eg. height, temperature, mass
What did Archimedes do about pi?
Archimedes made pi more precise
How do you use the word precision in a sentence?
Jennifer used precisely two cups of flour in the cake. The fastest sprinter ran forty yards in precisely 4.6 seconds. It is difficult to precisely estimate the number of homeless people in the city.
What is an specific and precise measurement called?
Synonyms of "specific" and "precise" include accurate, detailed, explicit, stringent or rigorous. A precise measurement is one made with well-maintained equipment and using the correct methods in a careful manner.
What is Fiberglass measuring tape?
A measuring tape made of fiberglass. I have 3, very smooth and much better than steel tapes.
Which of these measurements was made with the most precise measuring device 8.1956 m 8.20 m or 8.196 m?
8.1956 m
Why is measuring tape used by tailors not made of elastic?
Measuring tapes used by tailors are not made of elastic because elastic materials can stretch over time, leading to inaccuracies in measurements. A non-elastic measuring tape ensures consistent and precise measurements for tailoring garments.
Why is the use of zero-error necessary in a measuring instrument?
Zero-error is necessary in a measuring instrument because it ensures accuracy in measurements by accounting for any inherent discrepancies in the instrument itself. By calibrating the instrument to have a zero-error, any readings taken will be more reliable and consistent, allowing for more precise measurements to be made.
Are all factory-made cookies shaped the same and do they have the same measurements?
If you see roughly, then you will see that all factory-made cookies (of same type) have same shape and measurement. But if you use very precise measuring tools (such as vernier scale or screw gauge) you may find some difference.
What are calibrations?
Calibration is the validation of specific measurement techniques and equipment. At the simplest level, calibration is a comparison between measurements-one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device. This has been taken from Wikipedia and the link is added.
What is special in the construction of the apparatus used for measuring small volumes?
Apparatus used for measuring small volumes typically have a smaller scale division to allow for more precise measurements. They also often incorporate a burette or micropipette for accurate dispensing of liquids. Additionally, they may be made from materials that are resistant to corrosion and can be easily sterilized to prevent contamination.
Measuring cup laboratory apparatus?
A measuring cup is a simple laboratory apparatus used in scientific experiments to accurately measure the volume of liquids. It is typically made of glass or plastic and comes in various sizes, facilitating precise measurements for use in experiments and research. To ensure accuracy, measuring cups are calibrated to display volume markings in milliliters or cubic centimeters.
What is special in the construction of different instruments used for measuring small volumes?
Instruments used for measuring small volumes, such as micropipettes, require precise construction to ensure accurate and reproducible measurements. They often contain a piston mechanism that allows for precise volume adjustments and are made with materials that resist corrosion and ensure minimal retention of liquid. Additionally, these instruments may have a calibrated scale or digital display for easy reading of the measured volume.
Who needs to know how to use measuring tools?
Anyone who measures things and anyone who receives information concerning measurements made with tools.

What is the miniscus?
mEniscus is the curve or crescent of the surface on a liquid or substance and can be concave or convex. The meniscus should be taking in to account when a readings made to make precise measurements.
What is a measuring can?
A measuring can is a container typically used in laboratory settings to accurately measure and dispense liquids. It is equipped with a spout and graduations on the side to indicate volume measurements. They are often made from materials such as glass or plastic to ensure accuracy and ease of cleaning.
