The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is
. The third solution can be easily found using the rational root theorem, and it's equal to -1.
Answer:
It's B. 0.4
Step-by-step explanation:
the first probability is 0.6 and 0.6+x=1 so x is 0.4
You don't define the ratio, so there are two answers:
If 2/3 is boys to girls, then,
2/3 = 24/x
x = 36 girls
If 2/3 is girls to boys, then,
2/3 = x/24
x = 16 girls
