A ball is thrown downward with an initial velocity of 35 meters per second from a cliff that is 130 meters high. The height of the ball is given by the quadratic equation: h=-4.9 t^{2}[/tex]-35t+160 where h is in meters and t is the time in seconds since the ball was thrown. After how many seconds will the height of the ball be 30 meters? WILL GIVE BRAINLIEST!

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).
