Cimetidine oral syrup contains 40 mg/mL and a 61.6 lbs German Shepherd Dog requires 7 mg/kg TID. Approximately how many milliliters should the dog receive over the next 7 days?

Below is a boxplot of the arrival delay in minutes for flights arriving in Buffalo Niagara International Airport on a given day. The low outlier is most likely a system data error. The high outlier was a flight arriving from SFO that was diverted mid-flight due to storms over the central plains and eventually arrived in Buffalo over 12 hours late.   Removing both outliers will create what impact, if any, on the mean and median arrival delay for this data set? boxplot.jpg

Cloud Nova, a cloud computing company, manages 500 data servers that require routine maintenance to prevent unexpected failures. Each maintenance session takes 2 hours per server, while an unexpected failure results in 10 hours of downtime, costing $5,000 per hour. Without maintenance, each server has some probability of failure per week, which increases the longer it has been since the server has had a maintenance session. The company wants to use a simulation model to identify the optimal maintenance frequency (every 2, 4, or 6 weeks), balancing scheduled downtime with failure-related downtime. A) Identify the elements needed for the design of the simulation model: fixed inputs, random inputs and choice variable. B) Write 3 business questions for analysis that could be answered with a Monte Carlo simulation model in this business scenario. After completing the simulation modeling and trial runs, Cloud Nova’s management team was presented with the following visualization of the analytics output.   Sim_1.jpg C) Summarize the simulation findings, discussing each option’s simulated downtime costs, as well as the risk associated with each option. End with a recommendation to the management team for which maintenance frequency should be adopted. Support your recommendation.

The Human Resources Department of a large insurance agency presented the following report to their senior management team.  Briefly discuss any issues with the design of the HR Department’s initiative and threats to the validity of their conclusions.”We are pleased to present the results of a recent initiative aimed at enhancing job satisfaction and employee engagement within our organization.Initial Assessment: An in-depth analysis was conducted to gauge current levels of job satisfaction and engagement among staff who volunteered to participate in the program, utilizing validated assessment tools to establish a reliable baseline for comparison.Intervention: “EmpowerOne” ProgramDuration: 3-month long employee engagement programObjective: To catalyze positive change in employee engagement through strategic workshops and skill development sessions.Subsequent Evaluation: Following the “EmpowerOne” program, a thorough re-evaluation was carried out with the program participants to measure shifts in employee attitudes and engagement.Findings of the “EmpowerOne” Program: Job Satisfaction: There was a significant 60% increase in job satisfaction scores among participants, indicating a substantial rise in workplace contentment. Employee Engagement: Post-intervention data indicated a 45% enhancement in employee engagement metrics, reflecting a robust increase in active contribution and commitment to job roles.Renewed Vigor: A noteworthy elevation in participants’ energy levels and enthusiasm for their daily tasks was observed, suggesting a positive shift in workplace dynamics. “EmpowerOne” was a resounding success! We should invest the necessary resources to roll out the program to all of our employees, in order to enjoy these increased satisfaction and engagement metrics throughout the company. This initiative underscores our commitment to fostering a work environment that promotes personal growth and organizational success. The “EmpowerOne” program stands as a testament to our dedication to investing in our most valuable asset—our employees.”

A kindergarten teacher plans an activity where students listen to the word “cat” and then identify the first sound they hear. This activity primarily addresses which skill?

As an additional support to her five students struggling with the phonemic awareness lesson during whole group instruction, a kindergarten teacher uses Elkonin boxes with colored tiles. As the teacher says a word, the student moves a tile in a box for each sound they hear in the target word. The teacher calls on each student to tell her the sounds they hear in the word while touching the colored tiles. This strategy should enhance understanding of identifying sounds because:
