I’m attaching a photo. For each of these, start by multiplying both sides of the inequality by what’s in the denominator.
When drawing of the number lines, the circle is filled in if the any quality has an “equal than.” Otherwise, the circle is left open.
When dividing by a negative number, the direction of the inequality flips. Greater than becomes less than, and vice-versa.

Answer:
The number of ways of selection of 3 items taking 2 at a time in addition to the possible ways in which each girl selects the same style is 9 different ways. Since the list contains 9 different ways in which each of them can select a style, the list is complete.
Step-by-step explanation:
Here we have the number of ways the available styles can be arranged between each girl is given by the number of permutation of 3 items, taking two at a time plus the number of possible selections where both of them select the same style as follows
We note that the formula for permutation is
P
=
Therefore ₃P₂ = = 6 different ways
The number of possible selections where both of them select the same style is given by
(T, T), (s, s), (L, L) = 3 different ways
Total number of ways = 6 + 3 = 9 ways
Number of different ways available in the list = 9 ways
Therefore the list is complete
