Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :
The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
-(1/2)p<-16
Divide both sides by the coefficient of p. Flip the inequality sign because you are dividing a negative number.
p>32
Final answer: A
To find the probability, you need to divide the amount of red marbles by the total amount of marbles.
1/10 = 0.1.
The probability of choosing a red marble is 0.1, or 10%
A square root can’t be a negative value, so the root would be greater than or equal to zero.
Range:
Y>=O
