ANSWER
No real roots.
The roots are complex or imaginary.
EXPLANATION
The quadratic equation
has discriminant,
If the discriminant is less than zero , then the quadratic equation has no real roots.
The given discriminant is -9.
Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.
The number of permutations of 
objects from n objects is
Here 5 digits are chosen from 6 digits without replacement (order important).
The number of 5 digit numbers that can be formed is
Answer:

Answer:
-3 < x ≤ 4
Step-by-step explanation:
x is between -3 and 4, but -3 is not included in the solution set:
-3 < x ≤ 4
Answer:
Step-by-step explanation:
Since the fish bowl contains blue, green and red plastic fishes, it means that a fish picked at random would be any of these colors.
the probability of it being blue is 0.7 and the probability of it being green is 0.2, then probability of Matt picking a red fish is
1 - (0.7 + 0.2) = 0.1
If there are 60 fishes in the fish bowl, then the number of fishes that are red is
0.1 × 60 = 6 fishes
