Question

Marta measured the temperature as 65°f. what is the margin of error?

a. 60°f to 70°f
b.64°f to 66°f
c.64.5°f to 65.5°f
d.65.5°f to 66.5°f

Answer 1

The margin of error is usually one half unit on each side of the measured unit.

Subtract 0.5: 65 - 0.5 = 64.5

Add 0.5: 65 + 0.5 = 65.5

The answer would be c.64.5°f to 65.5°f
