Can some one me with this? : a python curls up to touch the tip of its own tail with its nose, forming the shape of a circle. the python is 2.6pi meters long. what is the radius r of the circle that the python forms?

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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.
