11. On Satunday, the high temprature was \( 22^{\circ} \mathrm{C} \) and the low temprature was \( 15^{\circ} \mathrm{C} \). Which inequality represents the temprature, \( t \), in this situation? a) \( 15 \leq t \) or \( t \geq 22 \) b) \( 15 \leq t \leq 22 \) c) \( 15 \geq t \geq 22 \) d) \( 15 \geq t \) or \( t \leq 22 \)

The correct inequality that represents the temperature \( t \) on that Saturday is \( 15 \leq t \leq 22 \). This indicates that the temperature was at least \( 15^{\circ} \mathrm{C} \) and did not exceed \( 22^{\circ} \mathrm{C} \). Understanding temperature ranges is vital in various fields, including agriculture and meteorology. Farmers depend on recorded temperature ranges to make informed decisions about planting and harvesting, while meteorologists use such data to predict weather patterns and alert the public to any potential climate issues.
