Question 1017332: The Fujita Scale (F-scale) is the official classification system for tornado damage. One factor used to classify a tornado is wind speed. According to the chart below, which inequality shows the range of wind speeds for an F4 tornado?
Graph:
f0: 40 - 72
f1: 73 - 112
f2: 113 - 157
f3: 158 - 206
f4: 207 - 260
f5: 261 - 318
Answers:
t < 207 or t > 260
t ≤ 207 or t ≥ 260
207 < t < 260
207 ≤ t ≤ 260

Thanks!
