Suppose certain coins have weights that are normally distributed with a mean of 5.315 and a standard deviation of 0.7 to a vending machine is configured to accept those coins with weights between 5.235 and 5.395 if 300 different coins are inserted into the vending machine what is the expected number of rejected coins

Ans: 0.9464*270 = 256 when rounded up

(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

chase is right because he already been to the swings and he know how far it will be to get there
