Answer
(a) $-7^o$ F
(b) $-33^o$ F
Work Step by Step
Use the table to find the "windchill" temperature.
(a)
$10^o$ F is in the 8th column while $15$ mph wind is in the 4th row of the first column.
The intersection of the 4th row and the 8th column is $-7$.
Thus, the "windchill" temperature is $-7^o$ F.
(b)
$-5^o$ F is in the 11th column while $35$ mph wind is in the 7th row of the first column.
The intersection of the 7th row and the 11th column is $-33$.
Thus, the "windchill" temperature is $-33^o$ F.
