A museum tests a model warming pack near a temperature-sensitive display. The pack passes the test only if the temperature never exceeds 37 °C during the first six minutes. A probe records one reading every two minutes.
| Elapsed time (min) | Temperature (°C) |
|---|---|
| 0 | 30 |
| 2 | 36 |
| 4 | 36 |
| 6 | 33 |
Question 1
Which statement is established by the recorded readings?
- The pack never exceeds 37 °C.
- The temperature is constant between minutes two and four.
- Every recorded temperature is at most 37 °C.
- The pack is hottest at exactly minute two.
Question 2
Explain why the readings at minutes two and four do not guarantee that the pack passes.
