The investigation that was carried out by the researcher illustrates a one-shot case study.

<h3>What is a one-shot case study?</h3>

It should be noted that a one-shot case study simply means a research design where a single group is observed after experiencing some treatment on a single occasion.

Since the researcher sits in the quad and records the number of minutes each student puts into studying, it's a one-shot case study.

Here, the single group of individuals are selected for observation.

If A = 8! and B = 8P8, then which one of the following is true:
meriva

Answer:

A. A = B

Step-by-step explanation:

Given

A = 8!

B = ^8P_8

Required

Which of the options is true

We start by simplifying B = ^8P_8

Permutation is calculated as follows

^nP_r = \frac{n!}{(n - r)!}

So.

^8P_8 =\frac{8!}{(8 - 8)!}

^8P_8 =\frac{8!}{0!}

0! = 1; So

^8P_8 =\frac{8!}{1}

^8P_8 =8!

Hence. B! = P!

<em>This implies that </em>A = B = 8!<em />
