Refer to the model Q (t) = Qe -0.000121 used for radiocarbon dating. At an archeological site, scientists uncovered human remains. A sample from a human bone taken from the site showed that 24.9% of the carbon-14 still remained. How old is the sample? Round to the nearest year. Do not round intermediate calculations. The sample from the human remains is approximately years old. X S 90 B 199 V
