Thats a of T is equal to a naught times one-half to the T over K where K is the half-life.

How can a carbon-14 calculator be used to determine the age of a fossil?

This is an example ofMoreA fossil contains 60% of its original carbon-14 how old is the fossil. This is an example of radioactive decay. So our equation is going to be a of T equals a naught e to the KT decay.

How old is a fossil that has 25% of the original amount of carbon-14?

The half-life for 14C is approximately 5700 years, therefore the 14C isotope is only useful for dating fossils up to about 50,000 years old. Fossils older than 50,000 years may have an undetectable amount of 14C. For older fossils, an isotope with a longer half-life should be used.

What is the formula for mode in grouped data?

Mode for grouped data is given as Mode=l+(f1−f02f1−f0−f2)×h , where l is the lower limit of modal class, h is the size of class interval, f1 is the frequency of the modal class, f0 is the frequency of the class preceding the modal class, and f2 is the frequency of the class succeeding the modal class.
