The combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3
<h3>Permutation and Combination</h3>
While combination has to do with selection, permutation has to do with arrangement.
According to the combination rule
nCr = n!/(n-r)!r!
The expression that gives the result of 20 is expressed below;
6C3 = 6!/(6-3)!3!
6C3 = 6!/3!3!
6C3 = 6!/6*6
6C3 = 720/36
6C3 =20
Hence the combination expression that demonstrates how the 20 is calculated using the combination pattern is 6C3

Answer:
The total number of registered doctors was 192,473.
Step-by-step explanation:
This question can be solved using a rule of three.
53700 is 27.9% = 0.279. The total number of registered doctors is x, which is 100% = 1. So
53700 doctors - 0.279
x doctors - 1



Rounding to the nearest whole number.
The total number of registered doctors was 192,473.

Answer:
z*(z - 3) = 520
Step-by-step explanation:
Use the following representations:
Width: W
Length: L = W + 3, or W = L - 3
Area = L*W = L*(L - 3) = 520
Equation b) is the correct one: z*(z - 3) = 520
