Astudent reports three trials to measure the density of an unknown metal. the percent error in these trials is given in the table. trial count percent error trial 1 0.05 trial 2 0.02 trial 3 0.01 indicate the most accurate valu

Trial 3 is most accurate because the percent error is 0.01.

Step-by-step explanation:

The table of percent error is given below.

Trial Count          Percent Error

   Trial 1                    0.05

   Trial 2                   0.02

   Trial 3                    0.01

A trial is most accurate if the percent error is minimum.

From the given table it is clear that the percent errors of three trials are 0.05, 0.02 and 0.01 respectively. The value 0.01 is least amount the given percent error.

Therefore, Trial 3 is most accurate.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

answer: -1
