students measure the length of a paper clip whose actual length is 3.2 cm. whose measurement are precise but not accurate?
samuel:2.7, 2.7, 2.7, 2.8
jose:2.2, 2.6, 3.0, 3.3
nikita:3.1, 3.1, 3.2, 3.2
anne:2.6, 3.2, 3.2, 3.6
ps help
Measure the width of the paper clip to the nearest millimeter.
To determine which measurements are precise but not accurate, we need to compare each measurement to the actual length of the paper clip, which is 3.2 cm.
Samuel's measurements: 2.7, 2.7, 2.7, 2.8
Based on these measurements, Samuel's measurements are not accurate because none of them match the actual length of 3.2 cm. However, they are precise because they are consistent with each other, with values ranging from 2.7 to 2.8 cm.
Jose's measurements: 2.2, 2.6, 3.0, 3.3
Jose's measurements are also not accurate because none of them match the actual length of 3.2 cm. However, they are not precise either because the values vary widely, ranging from 2.2 to 3.3 cm.
Nikita's measurements: 3.1, 3.1, 3.2, 3.2
Nikita's measurements are accurate because two of the values (3.2 cm) match the actual length of 3.2 cm. They are also precise because they are consistent with each other.
Anne's measurements: 2.6, 3.2, 3.2, 3.6
Anne's measurements are accurate because one of the values (3.2 cm) matches the actual length of 3.2 cm. However, they are not precise because the values vary, ranging from 2.6 to 3.6 cm.
Based on the above analysis, Samuel's measurements (2.7, 2.7, 2.7, 2.8) are precise but not accurate.
thankssssss
precise means the measurements are all close to each other
accurate means the measurements are all close to the true value
