A company produces metal pipes of a standard length, and claims that the variance of the length is at most 1.4 cm. One of its clients decides to test this claim, with an assumption that the population of pipe lengths is normally distributed. Which test statistic should the client plan to use?

(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:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

she will travel a distance in the range of 3 - 11 miles

is there supposed to be a picture here?
