Lila recorded the number of books she read each month for 5 months. The data is shown below: Month: 1 2 3 4 5 Books: 4 6 5 8 7 What is the average number of books Lila read per month over these 5 months?
- 6 ✓
- 5
- 7
- 8
Why: To find the average number of books read per month, add the total number of books and then divide by the number of months. Lila read 4 + 6 + 5 + 8 + 7 = 30 books in total. Then divide 30 by 5 months: 30 / 5 = 6. Thus, the average number of books Lila read each month is 6.
Imani is collecting data for her science project on plants. She measured the height of five different plants in her home over one week and recorded the following heights in centimeters: 15, 20, 18, 25, and 22. What is the average height of the plants Imani measured?
- 20 ✓
- 21
- 22
- 18
Why: To find the average height of the plants, add the heights together: 15 + 20 + 18 + 25 + 22 = 100. Then, divide the total by the number of plants (5): 100 / 5 = 20. Therefore, the average height of the plants is 20 cm.
Sofia collected data on the number of books read by students in her study group for a month. The data is as follows: Kenji read 5 books, Imani read 3 books, Noah read 4 books, and Carlos read 6 books. What is the average number of books read by the students in the group?
- 4.5 ✓
- 4
- 5
- 6
Why: To find the average number of books read, add the total number of books read by all students: 5 + 3 + 4 + 6 = 18. Then, divide the total by the number of students: 18 / 4 = 4.5. Therefore, the average number of books read by the students in the group is 4.5.
Mateo keeps track of the rainfall in his hometown over five consecutive days. The amounts of rainfall in inches are recorded as follows: 2, 1.5, 3, 0.5, and 2.5. What is the average rainfall over these five days?
- 1.8 ✓
- 1.5
- 2
- 2.2
Why: To find the average rainfall, you first add up all the amounts: 2 + 1.5 + 3 + 0.5 + 2.5 = 9 inches. Then, you divide the total rainfall by the number of days: 9 inches / 5 days = 1.8 inches. Therefore, the average rainfall over the five days is 1.8 inches.
Lila is keeping track of the number of books she reads each month. The table below shows the number of books she read over five months: January: 4, February: 6, March: 5, April: 7, May: 8. What is the average number of books Lila read per month over this five-month period?
- 6 ✓
- 5
- 7
- 8
Why: To find the average number of books Lila read per month, first add the total number of books read: 4 + 6 + 5 + 7 + 8 = 30. Then, divide the total by the number of months, which is 5: 30 / 5 = 6. Therefore, the average number of books Lila read per month is 6.
Carlos keeps track of the number of books he reads each month. The data from the last five months is shown in the table below: | Month | Books Read | |-------------|------------| | January | 3 | | February | 5 | | March | 2 | | April | 4 | | May | 6 | What is the average number of books Carlos read per month over these five months?
- 4 ✓
- 5
- 3
- 6
Why: To find the average number of books read, first add the total number of books: 3 + 5 + 2 + 4 + 6 = 20. Then divide this total by the number of months, which is 5: 20 / 5 = 4. Therefore, the average number of books Carlos read per month is 4.
Aisha keeps track of the number of books she reads each month. Here are the totals for the last four months: January - 6 books, February - 8 books, March - 7 books, and April - 9 books. What is the average number of books Aisha read per month over this four-month period?
- 7
- 7.5 ✓
- 8
- 8.5
Why: To find the average number of books Aisha read per month, add the number of books read each month and then divide by the number of months. Aisha read a total of 6 + 8 + 7 + 9 = 30 books. Since this covers 4 months, the average is 30 / 4 = 7.5. Therefore, the correct answer is 7.5.
Jamal is collecting data for his science project. He measured the heights of five plants in centimeters: 15, 20, 25, 30, and 35. What is the average height of the plants?
- 25 ✓
- 20
- 30
- 35
Why: To find the average height, first add all the heights together: 15 + 20 + 25 + 30 + 35 = 125. Then divide the total by the number of plants: 125 / 5 = 25. Therefore, the average height of the plants is 25 cm.
