Answer:
r < -7 or r > 10
Step-by-step explanation:
-2|3 - 2r| < -34
|3 - 2r| > 17 (Note the inequality sign flips because we divide by negative)
Now we split it up into 2 inequalities :-
3 - 2r > 17
-2r > 14
r < -7 (answer)
and
3 - 2r < -17
-2r < -20
r > 10 (answer).
There are

female teachers, and

male teachers.
This means that, out of a total of 75 teachers, 45 are female, leading to a probability of

So, out of a total of 21 teachers, there are 13 female teachers, leading to a probability of

of selecting a female teacher.
