1.5655 is your starting value, you need to both subtract and add 3 to that value to determine your range.

1.5655-3= -1.4345

1.5655+3= 4.5655

so your range is -1.4345 to 4.5655

Percentage error measures the error in relation to the quantity measured. For example if something weighs 100 grams with a possible error of plus or minus 5 grams, this is an error of 5%   A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9 the margin of error is the percentage of error that could be within a political study.

The idea of subtraction or addition was indicated by the determinative hieroglyph for "motion", a pair of legs joined at the knees - their direction indicated which mathematical process was required.   Take 8 minus 3 and that equals 5. Just act like the percent symbol isn't there. This is actually impossible, even for machines, but a zero error would mean there is no uncertainty in the measurement, as in no possibly plus or minus a unit.  Negative (minus) means that you are most likely not pregnant. a symbol or function denoting an operation, like plus or minus signs. ###### Math and ArithmeticAudio Editing and RecordingSynonyms and AntonymsScienceMicrosoft WindowsNumbers Jobs & EducationChemistryGeometryPolitics and GovernmentAncient EgyptEconomicsPercentages, Fractions, and Decimal ValuesPhysicsProbabilityPregnancy TestsAtoms and Atomic Structure Copyright © 2020 Multiply Media, LLC.
