A store sells packages of comic books with a poster. A poster and 6 comics cost $14.99. A poster and 14 comics cost $22.99. Write a linear function rule that models the cost y of a package containing any number x of comic books.
Suppose another store sells a similar package, modeled by a linear function rule with initial value $6.99. Use pencil and paper. Explain which store has the better deal.

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
