Question

A student used a ruler to measure a pencil, as shown below: A pencil beside a metric ruler. The ruler is scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number. One end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6. © 2010 Jupiterimages Corporation Which of the following measurements is both accurate and precise?

Answer 1

the measurement from the ruler states that the pencil is 5.5 centimeters long. so the missing options in this question would be,

55 mm

5 cm

44 mm

6 cm

so 55 mm in centimeters is 5.5 cm, so your answer would be 55 mm.

hope i helped. :)

Answer 2

Imagining the illustration where a pencil is beside a metric ruler, scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number and one end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6, we can conclude that the precise and accurate measurement of the ruler would 5.5 centimeters. Since the point is pointing in the midway of 5 and 6, we can interpret that the point is pointing in the exact half between 5 and 6 thus we can conclude that this would be a 0.5 addition to 5, giving us the 5.5 cm.
