Carbon dating is a technique used by archaeologists to estimate the age of organic remains. When organic remains are found, archaeologists measure the level of carbon 14 in the remains. That information, along with the known half-life of carbon 14 being about 5,730 years, is used to calculate the age of the organic remains. This graph models the percentage of carbon 14 remaining over the number of half-lives elapsed. Choose the statement that describes the meaning of the coordinate point (4,6.25) . Statement #1: When 6.25 half-lives have elapsed, there is 4 percent of the carbon 14 remaining. Statement #2: There is 6.25 percent of the carbon 14 remaining when 4 half-lives have elapsed. Statement #3: If 6.25 percent of half-lives have elapsed, then 4 percent of the carbon 14 remains. Statement #4: Four half-lives remain when 6.25 percent of the carbon 14 has elapsed. (1 point) Statement # describes the meaning of the coordinate point (4,6.25) .

Answer 1

Statement #1: When 6.25 half-lives have elapsed, there is 4 percent of the carbon 14 remaining.

Answer 2

This is statement #2

Answer 3

Apologies for the error in my response. The correct answer is indeed statement #2: There is 6.25 percent of the carbon 14 remaining when 4 half-lives have elapsed. Thank you for pointing that out.
