What is the value of the discriminant for the quadratic equation 0 equals X squared minus 4X +5 and how many number of real solutions does the equation have

Discriminant: -4

No real solutions

Step-by-step explanation:

You might remember this long, seemingly very hairy thing called the quadratic formula from earlier in algebra:

The discriminant of a quadratic equation of the form is that bit under the square root: . What does the discriminant tell us? Since we're taking its square root, we know that is only real for non-negative values of . If , we have two real roots, one for and one for . If , the function has a rational root, since the formula becomes

In your case, we have the equation ; here, , , and , so our discriminant is . Since we'd have a negative under our square root in the quadratic formula, we have no real solutions.

based on context clues you gave i'm assuming the answer would be c.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
