Answer:
-8
Step-by-step explanation:
-3x + 7x - 8 = 34 + 9x - 2
-3x + 7x - 9x = 34 - 2 + 8
-5x = 40|: (-5)
x = -8
A combination is a selection of part from a set of objects. In a combination the order of selecting object does not matters.
So we use combination for selecting 3 from the population of 10
We know combination of selecting 'r' objects from 'n' is nCr
We need to find 10C 3
= 120
120 different samples of size 3 can be taken from a finite population of size 10
