An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
Approximately 2.81 × 1 0 21 electrons flow through an electric device that delivers a current of 15.0 A for 30 seconds. This is calculated using the relationship between current, charge, and time, and converting charge to the number of electrons.

Create a segmented bar graph.
Segment the 'Adult Employees' bar into 13% (Discount), 17% (Vacation), and 30% (Lunch).
Segment the 'Minor Employees' bar into 18% (Discount), 11% (Vacation), and 11% (Lunch).
Label axes and segments appropriately.
Explanation
Understand the problem We are asked to create a segmented bar graph based on the provided relative frequency table. The table shows the preferences of adult and minor employees for different benefits. The graph will visually represent the distribution of these preferences for each employee type.
Plan the graph structure The segmented bar graph will have two bars, one for adult employees and one for minor employees. Each bar will be divided into three segments, representing the percentage of employees who prefer a 10% employee discount, an extra week of vacation, or longer lunch breaks.
Determine segment values For adult employees, the bar will be segmented as follows:
10% Employee Discount: 13%
Extra Week of Vacation: 17%
Longer Lunch Breaks: 30%
For minor employees, the bar will be segmented as follows:
10% Employee Discount: 18%
Extra Week of Vacation: 11%
Longer Lunch Breaks: 11%
Define graph axes and labels The y-axis of the graph will represent the relative frequency (percentage), ranging from 0% to 100%. The x-axis will represent the employee type (Adult Employees and Minor Employees). Each segment will be labeled with the corresponding benefit. The graph will have a title such as 'Employee Benefit Preferences by Employee Type'.
Final graph description The final segmented bar graph visually represents the employee benefit preferences for both adult and minor employees, with each segment showing the relative frequency of each benefit preference.
Examples
Segmented bar graphs are useful in visualizing survey data. For example, a company could use a segmented bar graph to display customer satisfaction levels across different product lines. Each bar would represent a product line, and the segments would represent the percentage of customers who are very satisfied, satisfied, neutral, dissatisfied, or very dissatisfied. This allows the company to quickly identify areas where customer satisfaction is high or low and make informed decisions about product improvements.
