Explain the use of plans and their importance in assessing the quality of pharmaceutical products. Provide a step-by-step design of a sampling plan based on a normal inspection for a 75,000 tablets with an AQL of 0.12% using the attached table (at the end of exam paper).
A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 9 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month? Express your answer as an integer.
9.16 According to Figure 9.2, the total energy supply in the United States in 2016 was 111.261015 Btu. Express this value in joules and in calories. FIGURE 9.2 Energy production and consumption (in quadrillion Btu) in the United States during the year 2016. The discussion in the text explains how to read this complex figure, which contains an enormous amount of information about the energy economy. Data come from the Department of Energy and do not always add up exactly as expected due to rounding and other issues.
The combustion of ammonia in the presence of excess oxygen yields NO2 and H2O: 4 NH3 (g) + 7 O2 (g) → 4 NO2 (g) + 6 H2O (g) The combustion of 261 g of ammonia consumes __________ g of oxygen. Atomic weights: N=14.01, H=1.01, O=15.99. Input values only with 2 decimal places.
The recommended daily dose of calcium for an 18-year-old male is 1200 mg. If 1.0 cup of whole milk contains 290 mg of calcium and milk is his only source of calcium source, how much milk should an 18-year-old male drink each day in mL? Suppose the child is lactose intolerant, do some research and explain what type of milk would be a good substitute for the child. Please give mg of calcium per cup of alternative milk value, and show calculations for how much of the alternative milk an 18-year-old male should drink each day in mL. (Hint: 1 cup = 236.588 mL) Show all work. Give numerical answers in 2 significant figures.
