Colored Wax & Co. sells candles with a mean burn time of 50 minutes. The company wants to test its candles' burn time against a competitor's candles. Researchers from Colored Wax & Co. randomly select 25 candles from its competitor for testing. From previous research, the staff of Colored Wax & Co. knows that σ = 12.5.

Suppose the mean burn time is actually 53 minutes. Find the possibility of a Type II error (β) and the power of the test.

List the sides of δrst in in ascending order (shortest to longest) if: a ∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

Select all of the following expressions that are equal to 2.5.

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i. e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
