Step-by-step explanation:

Representing inequalities on number line:

First of all we write the inequalities that are to be represented.

Let x represent the elevation of the miner at any time of the day.

The minimum elevation is 6 ft below the sea level. If we consider the sea level as 0 on the number line, the lower limit is -6.

The maximum elevation is 6 ft above the sea level. Hence the upper limit is 6.

The elevation throughout the day is represented by the inequality:

-6 ≤ x ≤ 6 and represented on the line as shown in the picture attached.

Note: The solid end points of the line at 6 and -6 means that 6 and -6 are included in the inequalities.

The table that shows the relative frequency of data is in the below further explanation.

<h3>Further explanation</h3>

A set is a clearly defined collection of objects.

To declare a set can be done in various ways such as:

With words or the nature of membership

With set notation

By registering its members

With Venn diagrams

$\texttt{ }$

Multiplying set A x B is by pairing each member of set A with each member of set B.

Example:

A = {1, 2, 3}

B = {a, b}

Then

A x B = {(1, a), (1, b), (2, a), (2, b), (3, a), (3, b)}

$\texttt{ }$

Union of set A and B ( A ∪ B ) is rewriting each member A and combined with each member B.

Intersection of set A and B ( A ∩ B ) is to find the members that are both in Set A and Set B.

Example:

A = {1, 2, 3, 4}

B = {3, 4, 5}

A ∪ B = {1, 2, 3, 4, 5}

A ∩ B = {3, 4}

Let us now tackle the problem!

$\texttt{ }$

A sports club has 84 members who learned baseball, and 42 of those members also learned basketball.

$\left[\begin{array}{ccc}&Play Baseball&Don't Play Baseball\\Play Basketball&\boxed{42}& \\Don't Play Basketball& & \end{array}\right]$

$\texttt{ }$

Number of members who learned baseball but did not learn basketball will be ( 84 - 42 ) = 42 members

$\left[\begin{array}{ccc}&Play Baseball&Don't Play Baseball\\Play Basketball&42& \\Don't Play Basketball&\boxed{42}& \end{array}\right]$

$\texttt{ }$

There are 25 students who did not learn baseball but learned basketball

$\left[\begin{array}{ccc}&Play Baseball&Don't Play Baseball\\Play Basketball&42&\boxed{25} \\Don't Play Basketball&42& \end{array}\right]$

$\texttt{ }$

8 students did not learn either baseball or basketball

$\left[\begin{array}{ccc}&Play Baseball&Don't Play Baseball\\Play Basketball&42&25 \\Don't Play Basketball&42&\boxed{8} \end{array}\right]$

$\texttt{ }$

Total Number of Students = 42 + 42 + 25 + 8 = 117

$\texttt{ }$

Table of relative frequency

$\left[\begin{array}{ccc}&Play Baseball&Don't Play Baseball\\Play Basketball&\boxed{\frac{42}{117}}&\boxed{\frac{25}{117}} \\Don't Play Basketball&\boxed{\frac{42}{117}}&\boxed{\frac{8}{117}} \end{array}\right]$
