At a dog training park, 10 dogs have just completed their training for the day and are being returned to their humans. For the last trick, the trainer randomly assigns each dog to a human and that dog runs to the randomly assigned human. What is the expected number of lucky pups who get assigned to their own human?

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

range is infinite on both x and y axis positive and negative

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
