Is (2, 3) a solution to the equation y = x - 1? yes or no
and pls explain for i can lead this already

Find the missing factor. 7s2 + 25s + 12 = (s + 3)( ).

What is the average rate of change for this function for the interval from x=2 to x=4 ?

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).
