| :---- | :--- | :--- | :---- | :--- | :----- | :--- | :--- |
| Hours | 5.5 | 12 | 9.5 | 11 | 7 | 10 | 8 |
Answer (1)
Calculate the total hours worked during the week: 5.5 + 12 + 9.5 + 11 + 7 + 10 + 8 = 63 .
Divide the total hours by the number of days in the week to find the average: 7 63 = 9 .
The average number of hours worked per day is 9.
The final answer is 9 .
Explanation
Understanding the Problem We are given the number of hours worked each day for a week and asked to find the average number of hours worked per day. To do this, we need to sum the hours worked each day and then divide by the number of days in the week, which is 7.
Calculating Total Hours First, we calculate the total number of hours worked during the week by summing the hours for each day: T o t a l Ho u rs = 5.5 + 12 + 9.5 + 11 + 7 + 10 + 8 = 63 So, the total number of hours worked during the week is 63 hours.
Calculating Average Hours Next, we divide the total number of hours by the number of days in the week (7) to find the average number of hours worked per day: A v er a g eHo u rs = 7 T o t a l Ho u rs = 7 63 = 9 Therefore, the average number of hours worked per day is 9 hours.
Final Answer The average number of hours worked per day is 9 hours.
Examples
Understanding averages is crucial in many real-life situations. For instance, if you're tracking your spending over a month, calculating the average daily expenditure can help you budget effectively. Similarly, in sports, a basketball player's average points per game helps assess their performance consistency. This concept is also fundamental in business for analyzing sales trends or production efficiency.
