Question
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.
The 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 # describes the meaning of the coordinate point (4, 6.25).
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.

The correct statement that describes the meaning of the coordinate point (4, 6.25) is:
**Statement #2: There is 6.25 percent of the carbon-14 remaining when 4 half-lives have elapsed.**
In this context, the x-coordinate (4) represents the number of half-lives elapsed, and the y-coordinate (6.25) represents the percentage of carbon-14 remaining. Thus, after 4 half-lives, 6.25% of the carbon-14 is left.
**Statement #2: There is 6.25 percent of the carbon-14 remaining when 4 half-lives have elapsed.**
In this context, the x-coordinate (4) represents the number of half-lives elapsed, and the y-coordinate (6.25) represents the percentage of carbon-14 remaining. Thus, after 4 half-lives, 6.25% of the carbon-14 is left.
