If cos A=28/53 and sin B=60/61 what is the value of sin(A-B)

0.358

Step-by-step explanation:

cos A=28/53 = 58.11

sin B=60/61 = 79.61

sin(79.11 - 58.11) = sin 21 = 0.358

your answer is d 2,500

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.
