Answer:

The organism died 35900 years ago

Step-by-step explanation:

Half life C-14 is 5730 years.
For decay of radioactive nuclides:
$(N)/(N_(0))=((1)/(2))^{\frac{t}{t_{(1)/(2)}}}$
is the fraction of radioactive nuclide remain present after t time and
$t_{(1)/(2)}$ is the half-life of radioactive nuclide
Here
is 0.013 and
$t_{(1)/(2)}$ is 5730 yeras

Plug-in all the values in the above equation:

$0.013=((1)/(2))^{(t)/(5730years)}$

So, t = 35900 years

Hence the organism died 35900 years ago
