Ashop owner, mr. smith, finds that each week 18% of his customers are between the ages of 12 and 15. during a three-week period, he served 450 customers. how many of them would you expect to be 12 to 15 years old?

(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

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

70.30

step-by-step explanation:

the answer would be 0.54
