The half-life of Carbon $, that is, the time required for half of the Carbon $ in a sample to decay, is variable: not every Carbon $ specimen has exactly the same half life.The half-life for Carbon $ has a distribution that is approximately normal with a standard deviation of $ years.For example, you can’t find the remaining amount of an isotope as 7.5 half-lives by finding the midpoint between 7 and 8 half-lives.This decay is an example of an exponential decay, shown in the figure below.

This task addresses a very important issue about precision in reporting and understanding statements in a realistic scientific context.We will deal with carbon dating first and then with the other dating methods.Carbon has unique properties that are essential for life on Earth.C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.
