An object was measured by a worker as
27.0cm long, however, the manufacturer
specifications list the length of the object at
27.7cm. what is the percent error in the
workers measurement?

2.5271%

Explanation:

The percent error is defined as;

(error/actual value) * 100%

In this case the error will be;

27.7cm - 27.0cm = 0.7cm

The actual value is 27.7cm since it is the one specified by the manufacturer.

The percent error in the worker's measurement is thus;

(0.7cm/27.7cm) * 100 = 2.5271%

the statement is true

the fossil record provides evidence of a common ancestor to many species.
