Answer:

89 2 irrational roots

Step-by-step explanation:

The discriminant Is b²-4ac when the equation is in the form

ax²+bx+c so in the equation

a=2 b=5 and c=-8

plug into the equation for the discriminant

so 5²-4(2)(-8)

25-(-64) 2 negatives make a positive so

Nitella [24]

Answer: 0.9730

Step-by-step explanation:

Let A be the event of the answer being correct and B be the event of the knew the answer.

Given: P(A)=0.9

P(A^c)=0.1

P(B|A^{C})=0.25

If it is given that the answer is correct , then the probability that he guess the answer P(B|A)= 1

By Bayes theorem , we have

P(A|B)=\dfrac{P(B|A)P(A)}{P(B|A)P(A)+P(C|A^c)P(A^c)}

=\dfrac{(1)(0.9)}{(1))(0.9)+(0.25)(0.1)}\\\\=0.972972972973\approx0.9730

Hence, the student correctly answers a question, the probability that the student really knew the correct answer is 0.9730.
