In a recent year, 19.4% of all registered doctors were female. If there were 52,500 female registered doctors that year, what wa

sukhopar [10]

Answer: 10,185 registered female doctors.

Step-by-step explanation: We basically want to find how many females were doctors, if 19.4% of the 52,500 females were registered doctors. Basically we want to find 19.4% of 52,500. We will write an equation that works to solve this problem.

19.4/100 = x/52,500 (This equation represents that 19.4% out of 100% is x out of the 52,500 registered doctors.) Solve for x.

19.4/100 x 52,500 = x/52,500 x 52,500.

(19.4 x 52,500 = 1,018,500/100 = 10,185. And, x/52,500 x 52,500 = x.

10,185 = x.

So, 19.4% of all registered doctors would be 10,185 females out of 52,500 females.

goldenfox [79]

Answer:

243 ways

Step-by-step explanation:

Calculating the number of posible outcomes:

We have n trials.

Each trial has m possible outcomes.

The total number of outcomes is:

$T = m^{n}$

In this question:

5 questions, that is, 5 trials, so $n = 5$

Each question has 3 options(True, false or unanswered). So $m = 3$

How many ways?

$T = 3^{5} = 243$
