Answer:
The numbers on this ruler represent centimeters. 1.70cm
What is the precision of this ruler?
What is the greatest possible error for the measurement indicated by the arrow?
What is the margin of error for the measurement based on where the arrow is pointing on the ruler?
Step-by-step explanation:
The required solutions are,
0.1 cm is the precision of this ruler
0.05 cm is the greatest possible error for the measurement indicated by the arrow.
1.65 cm to 1.75 cm is the margin of error for the measurement based on where the arrow is pointing on the ruler
What is a ruler?
A ruler is a mathematical tool, used to measure the lengths of objects.
Rulers are calibrated into various units of measurement such as meters, centimeters, and milimeters, etc.
Here,
A scale is given for 10cm measurements and an arrow is pointed over 1.70 cm on the ruler,
0.1 cm is the precision of this ruler because every line on the ruler is 0.1 cm of measurement.
0.05 cm is the greatest possible error for the measurement indicated by the arrow.
1.65 cm to 1.75 cm is the margin of error, because the error could arise to the nearest point on the ruler, for the measurement based on where the arrow is pointing on the ruler,
Thus, solutions for the given problem are described above.
