The number of ways can 8 people be seated in a circle if 3 people insist on sitting next to each other is 56 ways.
<h3>How to illustrate the information?</h3>
Combinations are also referred to as selections. Combinations implies the selection of things from a given set of things. In this case, we intend to select the objects.
Combination formula
nCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
This will be:
= 8! / (8 - 3!) 3!
= 8! / 5! 3!
= 8 × 7 × 6 / 3 × 2
= 5
There can be 56 ways.

You need more information. If you had the bmi's of every man between 20 and 29 you could get an exact answer. If you had a good sample you could get a good estimate of this answer.
Answer:
44.95
Step-by-step explanation:
Because I divided them together to get that
Using sampling concepts, it is found that this is an example of independent samples.
- For dependent samples, there is a paired measurement for one set of items.
- For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.
In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

Answer:
answer is
{X^2 + 4, X<2
{X + 4, X>2
Step-by-step explanation:
Because both solution set graph is at the begining hole at the value of X = 2 this means both sets doesn't contain 2.
