Carbon emission scope:  Typically refrigerant leaks belong to Scope 1 emission.  The heating/cooling consumption of its own data center belongs to scope 2 emission.  Scope 3 emission includes all upstream (i.e., cradle-to-gate) emissions from producing products and services purchased or acquired by the reporting company in the reporting year.

(Continued from the previous question) To counter no-shows, the airline is considering overbooking by selling 20 additional tickets, for a total of 220 tickets. The airline will be able to sell all 220 tickets given the high demand. If more passengers show up than there are available seats, the airline will have to compensate those passengers who cannot be accommodated. The compensation amount is normally distributed with a mean of $650 and a standard deviation of $100. Set up and run a simulation of 1,000 trials. Based on your simulation results, find and report the approximate probability that the revenue obtained from this overbooking strategy will exceed the revenue from Question 12. Would you recommend that the airline implement the overbooking policy? Why or why not?

Cruella, an aspiring fitness influencer, is trying to decide which workouts she should live stream on TikTok in the upcoming week. She is trying to balance between several alternatives, and factors that are important to her include “Intensity level”, “Morning workout?”, “Impressive for TikTok?”, and “Minutes per Livestream.” The workouts are rated as follows: Workout Running Yoga Strength Training HIIT Pilates Cycling Dance Intensity Level (1 = low, 4 = high) 4 1 3 5 2 4 3 Morning Workout? (1 = Yes, 0 = No) 1 1 0 0 0 0 0 Impressive for TikTok? (1 = low, 4 = high) 3 4 5 2 2 1 5 Minutes per Livestream 90 40 50 50 40 60 40 Cruella wants to maximize how impressive her live streams are (i.e., maximize the “Impressive for TikTok” score), while satisfying the following requirements: She can include only one workout that is scheduled for the morning She must complete at least 4 different workouts during the week. The average “Intensity Level” of her selected workouts must be at least 3. Cruella wants to set a limit on her total streaming time. The limit depends on whether or not she includes running, which is time-intensive. She will set either 280 minutes as her limit if she includes running, or 240 minutes if she does not include running. Let Xi = 1 if exercise i is chosen and 0 if not; i = 1 (Running), 2 (Yoga), 3 (Strength Training), 4 (HIIT), 5 (Pilates), 6 (Cycling), 7 (Dance). The binary decision variable implies that Cruella will stream each chosen workout only once during the week. Which four LINEAR constraints describe the four requirements above? Please check all four constraints.

The shadow price of a constraint represents the change in the optimal objective value if the right-hand-side of the constraint increased by ________________.

Determine if the following prompt describes an experiment or observational study. Waymo places complimentary water bottles in 50% of its autonomous vehicles, randomly selected through an algorithm. Over the course of a month, the system tracks ride ratings to determine whether offering water improves passenger satisfaction.

A client who has had cold symptoms for a week visits the local urgent care center with report of left ear discomfort, dizziness, and decreased hearing. What additional assessment findings would the nurse expect with otitis media?

Did you complete the Human Flourishing and Patient Centered Assignment Case Study?

A nurse contacts the primary health care provider after reviewing a client’s abnormal  laboratory results of a blood urea nitrogen (BUN) of 35 mg/dL (12.5 mmol/L) and a serum creatinine of 1.0 mg/dL (88.4 mcmol/L). What collaborative care measure would the nurse recommend?
