PLEASE HELP ME James is running around a square field. He starts at point A, then runs around the perimeter, passing through points B, C, and D, until he gets back to point A. Then he cuts across the diagonal to point C. In total, he covers 271 m. If AB¯¯¯¯¯¯ is 50 m long, what is the length of the diagonal AC¯¯¯¯¯¯?
A. 67.75 m
B. 17.75 m
C. 71 m
D. 221 m

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
