If a method produces a random error for each measurement of 4%, but a percent error of equal to or less than 1% is required for this value for later analysis, what is the minimum number of measurements that must be collected and averaged

7.05

Explanation:

Random error is = 0.282

Remember ( random error / total sum of errors ) x 100 = 4%

Which is 0.282/ total sum of errors = 428.2

Total sum of errors = 7.05

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

the answer is 0.8m.
