The latest 4K TVs are very sophisticated pieces of technology. They have to be built to a very high standard. All companies employ a quality control person to make random tests regularly to make sure 95% of the 4K TVs they build meet their standards. The null hypothesis of the test is that the proportion of all 4K TVs produced meet a specified standards is equal to 95 percent. The alternative hypothesis is that the proportion of all 4K TVs produced that meet their standards is greater than 95%. Which of the following describes a Type I error that could result from the test?

Big boi and travis scott are performing at the super bowl. travis scott is 62 years younger than twice big boi’s age. the sum of their ages is 70 years old. use b to represent big boi’s age. write and solve an equation.

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.)

Xy x xy if a and b are positive integers such that a*b=9 and b*a=72 what is the value of a/b
