Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences ab
1 answer:
Answer: 6,77,040 different random samples of four accounts are possible.
Step-by-step explanation:
We have to calculate the different random samples of four accounts are possible from the population of 65 bank accounts.
we are using combination formula for calculating various combination of four accounts:
=
Where,
n - total population of bank accounts
r - random samples drawn from the population
=
=
=
=
= 6,77,040 different random samples of four accounts are possible.

Answer:
Step-by-step explanation:
we would like to figure out the derivative of the following:
to do so, let,
By simplifying we acquire:
use law of exponent which yields:
take derivative in both sides:
use sum derivation rule which yields:
By constant derivation we acquire:
use exponent rule of derivation which yields:
simplify exponent:
two negatives make positive so,
by law of exponent we acquire:
simplify addition:
and we are done!
