Ayearbook printer charges based on the number of pages printed. here is a table that shows the cost of some recent yearbooks.
number of pages 50 100 150 200
cost 1.75 2.55 3.35 4.15
which equation gives the cost, y, in terms of the number of pages, x?

Solve the equation x/4 - 5= -8 -27 -12 -7 12

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).

Solve the equation by completing the square. x^2+2x=17
