Please help; I have no idea how to solve this!! The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F

) using the formula F(C)= 9/5C+k, where k is a constant. Find k, if to C=−40°C corresponds F=−40°F.

amid [387]

From 2 to 101 , the perfect square numbers are ,

4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .

Total number of possible outcomes = 100.

Total number of favourable outcomes = 9 .
