NUMERIC RESPONSE
1. The temperature-humidity index I (or humidex, for short) is the perceived air temperature
when the actual temperature is T and the relative humidity is h, so we can write I = f (T, h).
The following table of values of I is an excerpt from a table compiled by the National Oceanic
and Atmospheric Administration. For what value of T is ?
