Me solve this: cos^2x=0.36, find sin^2x

The useful trig identity is

... cos(x)² + sin(x)² = 1

Then

... sin(x)² = 1 - cos(x)²

For your value of cos(x)² = 0.36, this becomes

... sin(x)² = 1 - 0.36 = 0.64

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.
