To find the rate of change in the number of entries from 2014 to 2017, we first identify the number of entries in those years:
- In 2014, there were 37 entries.
- In 2017, there were 44 entries.
Next, we calculate the change in the number of entries:
Change in entries = Entries in 2017 - Entries in 2014
Change in entries = 44 - 37 = 7 entries
Now, we need to determine the number of years between 2014 and 2017:
Number of years = 2017 - 2014 = 3 years
Now, we can calculate the rate of change:
Rate of change = Change in entries / Number of years
Rate of change = 7 entries / 3 years ≈ 2.3333 entries per year
Finally, rounding to the nearest tenth:
Rate of change ≈ 2.3 entries per year
Thus, the rate of change between 2014 and 2017 is approximately **2.3 entries per year**.
- In 2014, there were 37 entries.
- In 2017, there were 44 entries.
Next, we calculate the change in the number of entries:
Change in entries = Entries in 2017 - Entries in 2014
Change in entries = 44 - 37 = 7 entries
Now, we need to determine the number of years between 2014 and 2017:
Number of years = 2017 - 2014 = 3 years
Now, we can calculate the rate of change:
Rate of change = Change in entries / Number of years
Rate of change = 7 entries / 3 years ≈ 2.3333 entries per year
Finally, rounding to the nearest tenth:
Rate of change ≈ 2.3 entries per year
Thus, the rate of change between 2014 and 2017 is approximately **2.3 entries per year**.
