Transcribed Image Text:**Radioactive Decay Observation**
A 200 mg sample of a radioactive substance is observed as it decays. The following table shows the mass remaining at various times, using an exponential decay model to calculate the half-life of the substance. Calculation should employ the least squares method. (See Section 6.7 for further guidance. Round your answer to the nearest day.)
| Time (days) | Mass (mg) |
|-------------|-----------|
| 0 | 200 |
| 30 | 170 |
| 60 | 145 |
| 90 | 124 |
To analyze this data, observe that as time progresses, the mass of the substance decreases, demonstrating an exponential decay pattern. Use this table to find the half-life by fitting an exponential decay curve using the least squares method.
