Enter the exponential decay function described in the situation and answer the question
asked. You may find using a graphing calculator helpful in solving this problem.
Carbon-14 is a radioactive isotope of carbon that is used to date fossils. There are about 1.5
atoms of carbon-14 for every trillion atoms of carbon in the atmosphere, which known as
1.5 ppt (parts per trillion). Carbon in a living organism has the same concentration as
carbon-14. When an organism dies, the carbon-14 content decays at a rate of 11.4% per
millennium (1,000 years). Write the equation for carbon-14 concentration (in ppt) as a
function of time (in millennia) and determine how old a fossil must be that has a measured
concentration of 0.3 ppt. Round your answer to two decimal places.

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
