11395610 — 2025-09-30 11:39:39 UTC

because precision needs multiple measurements

218619_2 — 2025-09-30 11:39:46 UTC

A single measurement is not enough to determine precision because precision refers to the consistency or repeatability of results.

220577_18 — 2025-09-30 11:41:00 UTC

False, you should wait for your instructor to tell you what to do next.

precision can only be determined by a large number of measurements

228004_13 — 2025-09-30 11:41:24 UTC

[does not effectively answer the question - see other student responses or look it up - PUPELLO]

1122405 — 2025-09-30 11:41:36 UTC

without multiple measurements its hard to point our errors and collect data

[Does not effectively answer the question - see other student responses or look it up - PUPELLO]

207605_3 — 2025-09-30 11:42:01 UTC

true; a single measurement isn't enough to determine precision because you can't measure all things with the same measurement in case of a reaction, etc.

225670_3 — 2025-09-30 11:43:44 UTC

precision refers to the consistency or repeatability of a set of measurements. To know if your measurements are consistent, you must have more than one to compare them to.

220577_18 — 2025-09-30 11:46:36 UTC

A single measurement can't tell you how precise your measurement is because precision is all about how consistently you get the same result. If you only measure once, you have no way of knowing if you'd get the same result if you measured again.

because there is nothing to compare it to since precision is when measurements are close to one another but not necessarily near the intended target.

1888041 — 2025-09-30 11:47:57 UTC

[Not completely correct - see other student responses or look it up - PUPELLO]

221055_30 — 2025-09-30 11:53:34 UTC

because you need way more measurements to pinpoint the exact location and its also not about measurements but the power you put into the ball

1788991 — 2025-09-30 11:55:35 UTC

precision is a measure of thzzze consistency or repeatability of a result

[Incorrect - see other student responses or look it up - PUPELLO]

225975_4 — 2025-09-30 12:06:35 UTC

because precision is measurements near the pin pointed location not directly it

[Does not answer the question. See other student responses - PUPELLO]

226237_7 — 2025-09-30 12:11:11 UTC

No ,a single measurement is not enough to determine accuracy because the quantity may vary and this can lead to error.

false

185390_7 — 2025-09-30 12:11:17 UTC

false

185390_7 — 2025-09-30 12:12:34 UTC

Precision refers to the repeatability and consistency of a set of measurements and not individually.

185390_7 — 2025-09-30 12:15:02 UTC

225670_3 — 2025-10-07 11:37:47 UTC

8.25 inches is more precise than 8 inches. The level of precision is often associated with the number of significant figures used.

218619_2 — 2025-10-07 11:38:25 UTC

8.25 inches is a more accurate measurement than 8 inches because it provides more information about the true value being measured.

[Explain what you mean; be specific - PUPELLO] 8.25 because its more accurate

1862961 — 2025-10-07 11:40:08 UTC

8.25 refers to how consistent or repeatable a measurement is, indicated by the number of decimal places or significant figures.

1888041 — 2025-10-07 11:42:28 UTC

220577_18 — 2025-10-07 11:46:08 UTC

8.25 inches is more accurate because it includes a more precise measurement to the hundredths place, whereas 8 inches is only accurate to the nearest whole number.

demarqus sanders

221055_30 — 2025-10-07 11:51:15 UTC

8.25 because providing more numbers is being more specific and accurate

[Explain what you mean; be specific - PUPELLO] 8.25 because there's decimals

228004_13 — 2025-10-07 11:52:42 UTC

Accuracy

226237_7 — 2025-10-07 11:52:56 UTC

8.25 inches is more accurate precise because it has more significant figures .

1788991 — 2025-10-07 11:58:02 UTC

The measurement of 8.25 inches is more accurate because it has more significant figures and a smaller possible error. Accuracy in measurement is about how close a measured value is to the true value.

[Add your LAST NAME please - Explain what you mean; be specific - PUPELLO]

2025-10-07 12:04:17 UTC

maybe they put 8.25 to be specific than the number been whole

Qisir Jones

1118914 — 2025-10-07 12:04:45 UTC

Based on the principles of significant figures and precision, 8.25 inches is a more precise measurement than 8 inches, but that does not mean it is more accurate.

2025-10-07 12:06:35 UTC

False if it contains liquid it would be dangerous since the liquid that we use could be poison or deadly it would be better asking the teacher to get rid of them.

[Put on safety equipment - PUPELLO]

[Add your LAST NAME please - [Explain what you mean; be specific - PUPELLO]

2025-10-07 12:16:49 UTC

8.25 is a more accurate measurment and 8 would basically be a estimate of the exact number

[Explain what you mean; be specific - PUPELLO] 8.25 because it goes into more depth about the number

115193_10 — 2025-10-07 12:19:05 UTC

207605_3 — 2025-10-07 14:35:09 UTC

8.25 inches is more accurate because it's more precise than just 8 inches
