Answer:
Step-by-step explanation:
Given the various variance of normal body temperature expressed by the function f(t) = |98.6-x| where x is persons current body temperature in degree Fahrenheit.
If medical professional says that healthy individual cannot have a variance of no more than 0.5F, we can get the variance by substituting x = 0.5 into the modeled function as shown;
Note that the function can either be negative or positive because of the modulus sign
If x = 0.5
For positive value,
f(0.5) = 98.6-0.5
f(0.5) = 98.1
If the function is negative
f(0.5) = -(98.6-0.5)
f(0.5) = -98.6+0.5
f(0.5) = -98.1
The variance for healthy individual will be expressed as -98.1≤f(x)≤98.1
