Answer :
Final answer:
To convert the infant's temperature of 100.4 degrees F to Celsius, the formula C = (F - 32) × 5/9 is used, resulting in 38.0 degrees C.
Explanation:
The student is asking about converting a temperature from Fahrenheit to Celsius. To convert a temperature from Fahrenheit to Celsius, we can use the formula C = (F - 32) × 5/9, where F is the temperature in Fahrenheit and C is the temperature in Celsius.
In the case of the 4-month old infant with a temperature of 100.4 degrees F, the conversion would look as follows:
C = (100.4 - 32) × 5/9
C = (68.4) × 5/9
C = 342 / 9
C = 38.0 degrees C
Therefore, the correct option is 2) 38.0 degrees C.
