Answer:

an= 12 + (-6)(n-1)

Step-by-step explanation:

you should find two values: a1 and d

a1= first number =12

d= a number of the sequence mines the number of the sequence before the one you chose = 0-6 = -6

a1+(n-1)d= 12-6(n-1)

What value is a permutation of n things taken r at a time divided by to get the combination of n things taken r at a time?

Lera25 [3.4K]

Answer:

A. r!

Step-by-step explanation:

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

Permutation of n things taken r at a time

$P_{(n,r)} = \frac{n!}{(n-r)!}$

Combination of n things taken r at a time:

$C_{n,r} = \frac{n!}{r!(n-r)!}$

Division:

$\frac{P_{(n,r)}}{C_{n,r}} = \frac{\frac{n!}{(n-r)!}}{\frac{n!}{r!(n-r)!}} = \frac{n!}{(n-r)!} \times \frac{r!(n-r)!}{n!} = r!$

So the correct answer is:

A. r!
