Final answer:
The total number of registered doctors is approximately 133,434.
Step-by-step explanation:
To find the total number of registered doctors, we can use the fraction of female doctors and the given number of female doctors.
Since 32.9% of all doctors are female, this means that 0.329 of the total number of doctors are female.
We can set up the equation:
0.329 * Total number of doctors = Number of female doctors
Substituting the given values, we have:
0.329 * Total number of doctors = 43,900
To solve for the total number of doctors, we divide both sides of the equation by 0.329:
Total number of doctors = 43,900 / 0.329
Simplifying this calculation gives us:
Total number of doctors ≈ 133,434
