Answer:
-1 < x < 4
Step-by-step explanation:
First separated the compound
-14 < 4x - 10
4x - 10 < 6
Then solved for each
-14 < 4x - 10
-4 < 4x
-1 < x
4x - 10 < 6
4x < 16
x < 4
Then put the inequality together (if applicable)
-1 < x < 4

Answer: 1020 ways
Step-by-step explanation:
Let C= comedy
Let M= Mystery
Number of movies(comedy) = 10
Number of movies (mystery) = 10
The total number of movies from which selection is to be made is 10 + 10
= 20
We want to pick 3 movies from 10 comedies and 10 mysteries with at least one mystery.
The selection will be from;
Unconditional selection - (0 mysteries)
=unconditional selection - ( all comedy included)
= 20C3 - 10C3 For combination, [nCr = n! /(n-r) r! ]
= [20!/(20-3)!3!] - [10!/(10-3)!3!
= (6840/6) - (720/6)
= 1140 - 120
= 1020 ways
