If 1 is one of the zeros of the polynomial x²- x + k then the value of k will be ?​

0

Step-by-step explanation:

The sum of the roots of the equation is and products of the root is

Here one of the root is 1.

Let the other option p

Now,

Sum of the roots =p×1 =1

  that means p=0

Product of the roots = p×1=k

k=0

Therefore, answer will be 0.

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%
