The relationship between B, the boiling point of water in degrees Celsius, and x, the vertical height above the sea level in meters, is given by B=100+mx. It is given that the boiling point of water is 64 degrees Celsius at a height of 10 km. a) Find the value of m.
b) if water boils at the top of the Alphubel in Switzerland at 84 degrees Celsius, find the height of the top of the Alphubel above the sea level.

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

This is different from the first one can someone me

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).
