Suppose a body with weight W is pulled along a flat plane by a drag force which acts alongside a string fixed to the body. If the string creates an angle θ with the flat plane, then the drag force is F = μW μ sin θ + cos θ where the coefficient of friction is denoted by μ. Note that μ and W are constants. Determine such a θ for which F is minimum. Also evaluate that minimum value.

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.
