Find the amount (percent of one gram) of carbon-14 lasting less than 5,730 years. This means, find P(x < 5,730).
a. Sketch the graph, and shade the area of interest
b. Find the probability. P(x < 5,730) = __________
Carbon-14 is a radioactive element with a half-life of about
5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14.
We are interested in the time (years) it takes to decay carbon-14. The distribution for X is ______.
A distribution is given as . What is ? Find thepercentile.
