Final answer:Inequalities are a way of describing the relationship between two values in mathematics. For example, 'x ≤ 4' means that 'x' is less than or equal to 4. They can be used to define a range of possible values for 'x', or to represent probabilities.Explanation:The subject here relates to solving an inequality in mathematics. An inequality describes the relative size or value of two values. Let's consider the statement '1.5 ≤ x ≤ 4.5'. This means thatxcan be any number between 1.5 and 4.5, inclusive. Solving for 'x' in this case simply means identifying those possible values.For example, if we wanted to express 'x is less than or equal to 4', we would write this as 'x ≤ 4'. Likewise, 'x is greater than 4' is 'x > 4'. 'X equals 4' would be 'x = 4', and so on.We can also use inequalities to describe probabilities. For instance, the probability that 'x' is between zero and two can be represented as '0 ≤ x ≤ 2', and we might specify that this probability equals 0.1, or 10%Learn more about Inequalities here:brainly.com/question/30231190#SPJ11...
