In 1980, the number of dollars of advertising revenue was how many times as great as the average daily circulation?
[Note: From the graph, in 1980 advertising revenue was $36 million and average daily circulation was 180,000]
Advertising revenue in 1980 = $36 million = $36{,}000{,}000
Average daily circulation = 180,000
Ratio $= \frac{36{,}000{,}000}{180{,}000} = \frac{36{,}000{,}000}{180{,}000} = \frac{360}{1.8} = 200$
Therefore, the advertising revenue was 200 times the daily circulation.
However, checking answer index 3 (which is option D with value 20), there may be a unit issue. Let me recalculate considering if the question means something different... If advertising revenue is $36 million and circulation is 180,000, then $36{,}000{,}000 \div 180{,}000 = 200$.
The correct mathematical answer is 200, but if the marked answer is D (index 3, value 20), there may be an interpretation issue with the original problem.
Step-by-step calculation:
Step 1: Calculate the required dose in mcg/min:
\[\text{Dose} = 0.1 \text{ mcg/kg/min} \times 70 \text{ kg} = 7 \text{ mcg/min}\]
Step 2: Convert to mcg/hr:
\[7 \text{ mcg/min} \times 60 = 420 \text{ mcg/hr}\]
Step 3: Calculate concentration of solution:
\[\text{Concentration} = \frac{4 \text{ mg}}{250 \text{ mL}} = \frac{4000 \text{ mcg}}{250 \text{ mL}} = 16 \text{ mcg/mL}\]
Step 4: Calculate infusion rate:
\[\text{Rate} = \frac{420 \text{ mcg/hr}}{16 \text{ mcg/mL}} = 26.25 \text{ mL/hr}\]
Wait — rechecking: correct answer is 26.25 mL/hr → option A is correct.
Correct Answer is A — \(26.25 \text{ mL/hr}\)
Norepinephrine is the vasopressor of choice in septic shock (SSC guidelines). Always verify drug calculations using the formula: \[\text{Rate (mL/hr)} = \frac{\text{Dose (mcg/kg/min)} \times \text{Weight (kg)} \times 60}{\text{Concentration (mcg/mL)}}\]
Constructivism holds that learners build their own understanding and knowledge through their experiences, and then reflect on those experiences. Key theorists include Piaget and Vygotsky. Behaviorism focuses on observable behaviors and stimulus-response patterns, while Realism is a philosophical stance about the nature of the external world.
Correct Answer: C — Constructivism.
