The weights of thoroughbred racehorses are normally distributed with a mean of 1140 pounds and a standard deviation of 100 pounds find the probability that a thoroughbred racehorse race weighs between 1000 and 1250.

(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

step-by-step explanation:

the shape,the size and the distance

slope intercept form is y = mx + b

i think this is a open ended question but i agree with other guy who said you should ask it at english section
