Question

Will measured the diameter of a penny as 1.9 cm using the ruler

Answer 1

What is the margin of error?

1.5 cm to 2.0 cm
1.5 cm to 2.5 cm
1.85 cm to 1.95 cm
1.90 cm to 1.95 cm

Answer 2

Since the scale is 1 mm, the margin of error is half a millimeter either way.

Answer 3

It will be either side of 1.9

Answer 4

1.90 cm to 1.95 cm

Answer 5

Thanks guys!

Answer 6

No, it's not 1.90 to 1.95
You need 0.05 less and 0.05 more than 1.9
That's what I mean by 0.05 to either side of 1.9
