To analyze the rate of change of the number of items packed with respect to time, we can calculate the number of items packed per minute over the different time intervals given.
Let's look at the data provided and calculate the rate of change:
- For 4 minutes: 20 items packed
- For 6 minutes: 20 items packed
- For 12 minutes: 44 items packed
- For 14 minutes: 50 items packed
Now let’s check the intervals:
1. From 4 to 6 minutes:
- Items packed = 20 - 20 = 0
- Time interval = 6 - 4 = 2 minutes
- Rate of change = 0 items / 2 minutes = 0 items per minute
2. From 6 to 12 minutes:
- Items packed = 44 - 20 = 24
- Time interval = 12 - 6 = 6 minutes
- Rate of change = 24 items / 6 minutes = 4 items per minute
3. From 12 to 14 minutes:
- Items packed = 50 - 44 = 6
- Time interval = 14 - 12 = 2 minutes
- Rate of change = 6 items / 2 minutes = 3 items per minute
Now summarizing the rates of change for each interval:
- From 4 to 6 minutes: \(0\) items per minute
- From 6 to 12 minutes: \(4\) items per minute
- From 12 to 14 minutes: \(3\) items per minute
Based on the calculations, the rate of change of the number of items packed in boxes varies over time, indicating that the worker's packing efficiency is not constant.
In conclusion, the statement describing the rate of change is that the rate of packing items varies depending on the time intervals, showing an increase from 0 to 4 items per minute in the earlier intervals, and then a decrease to 3 items per minute later on.
Let's look at the data provided and calculate the rate of change:
- For 4 minutes: 20 items packed
- For 6 minutes: 20 items packed
- For 12 minutes: 44 items packed
- For 14 minutes: 50 items packed
Now let’s check the intervals:
1. From 4 to 6 minutes:
- Items packed = 20 - 20 = 0
- Time interval = 6 - 4 = 2 minutes
- Rate of change = 0 items / 2 minutes = 0 items per minute
2. From 6 to 12 minutes:
- Items packed = 44 - 20 = 24
- Time interval = 12 - 6 = 6 minutes
- Rate of change = 24 items / 6 minutes = 4 items per minute
3. From 12 to 14 minutes:
- Items packed = 50 - 44 = 6
- Time interval = 14 - 12 = 2 minutes
- Rate of change = 6 items / 2 minutes = 3 items per minute
Now summarizing the rates of change for each interval:
- From 4 to 6 minutes: \(0\) items per minute
- From 6 to 12 minutes: \(4\) items per minute
- From 12 to 14 minutes: \(3\) items per minute
Based on the calculations, the rate of change of the number of items packed in boxes varies over time, indicating that the worker's packing efficiency is not constant.
In conclusion, the statement describing the rate of change is that the rate of packing items varies depending on the time intervals, showing an increase from 0 to 4 items per minute in the earlier intervals, and then a decrease to 3 items per minute later on.

To analyze the rate of change of the altitude of the airplane with respect to time, we will look at the given data points and calculate the altitude changes over the time intervals.
### Given Data
- At \(x = 1.5\) minutes, \(y = 28,000\) feet
- At \(x = 4.25\) minutes, \(y = 24,500\) feet
- At \(x = 3\) minutes, \(y = 19,000\) feet
### Finding the Rate of Change
We'll calculate the altitude change between each pair of times.
1. **From 1.5 to 4.25 minutes:**
- Change in altitude: \(24,500 - 28,000 = -3,500\) feet
- Change in time: \(4.25 - 1.5 = 2.75\) minutes
- Rate of change: \(-3,500 \text{ feet} / 2.75 \text{ minutes} \approx -1,272.73\) feet per minute
2. **From 1.5 to 3 minutes:**
- Change in altitude: \(19,000 - 28,000 = -9,000\) feet
- Change in time: \(3 - 1.5 = 1.5\) minutes
- Rate of change: \(-9,000 \text{ feet} / 1.5 \text{ minutes} = -6,000\) feet per minute
3. **From 3 to 4.25 minutes:**
- Change in altitude: \(24,500 - 19,000 = 5,500\) feet
- Change in time: \(4.25 - 3 = 1.25\) minutes
- Rate of change: \(5,500 \text{ feet} / 1.25 \text{ minutes} = 4,400\) feet per minute
### Summary of Rates:
- From 1.5 to 4.25 mins: approximately -1,273 feet/minute
- From 1.5 to 3 mins: -6,000 feet/minute
- From 3 to 4.25 mins: approximately 4,400 feet/minute
From this analysis, we can see that the altitude of the airplane is decreasing during the first two time intervals and then increasing in the last interval.
### Filling in the Blanks
Given that the overall pattern shows a significant decrease in altitude at the lowest of the intervals you provided (specifically the largest negative rate calculated):
1. **The altitude of the airplane:**
- **Decrease**
2. **Fill this blank with a number:**
- The most significant decrease in altitude occurs at around 6,000 feet per minute from 1.5 to 3 minutes.
3. **Fill this blank with the rate of:**
- **6,000 feet per minute**
Therefore, the completed statement would be:
- The altitude of the airplane **decrease** by **6,000** feet per minute.
### Given Data
- At \(x = 1.5\) minutes, \(y = 28,000\) feet
- At \(x = 4.25\) minutes, \(y = 24,500\) feet

- Rate of change: \(-3,500 \text{ feet} / 2.75 \text{ minutes} \approx -1,272.73\) feet per minute
2. **From 1.5 to 3 minutes:**
- Change in altitude: \(19,000 - 28,000 = -9,000\) feet
- Change in time: \(3 - 1.5 = 1.5\) minutes
- Rate of change: \(-9,000 \text{ feet} / 1.5 \text{ minutes} = -6,000\) feet per minute
3. **From 3 to 4.25 minutes:**
- Change in altitude: \(24,500 - 19,000 = 5,500\) feet
- Change in time: \(4.25 - 3 = 1.25\) minutes
- Rate of change: \(5,500 \text{ feet} / 1.25 \text{ minutes} = 4,400\) feet per minute
### Summary of Rates:
- From 1.5 to 4.25 mins: approximately -1,273 feet/minute

To determine the rate of change of the altitude of the airplane, we will calculate the altitude changes at various time intervals based on the given data.
### Given Data
- At \(x = 1.5\) minutes, \(y = 28,000\) feet
- At \(x = 3\) minutes, \(y = 19,000\) feet
- At \(x = 4.25\) minutes, \(y = 24,500\) feet
### Finding the Rate of Change
1. **From 1.5 to 3 minutes:**
- Change in altitude:
\[
y_2 - y_1 = 19,000 - 28,000 = -9,000 \text{ feet}
\]
- Change in time:
\[
x_2 - x_1 = 3 - 1.5 = 1.5 \text{ minutes}
\]
- Rate of change:
\[
\text{Rate} = \frac{-9,000 \text{ feet}}{1.5 \text{ minutes}} = -6,000 \text{ feet per minute}
\]
2. **From 3 to 4.25 minutes:**
- Change in altitude:
\[
y_3 - y_2 = 24,500 - 19,000 = 5,500 \text{ feet}
\]
- Change in time:
\[
x_3 - x_2 = 4.25 - 3 = 1.25 \text{ minutes}
\]
- Rate of change:
\[
\text{Rate} = \frac{5,500 \text{ feet}}{1.25 \text{ minutes}} = 4,400 \text{ feet per minute}
\]
3. **From 1.5 to 4.25 minutes (overall change):**
- Change in altitude:
\[
y(4.25) - y(1.5) = 24,500 - 28,000 = -3,500 \text{ feet}
\]
- Change in time:
\[
x(4.25) - x(1.5) = 4.25 - 1.5 = 2.75 \text{ minutes}
\]
- Rate of change:
\[
\text{Rate} = \frac{-3,500 \text{ feet}}{2.75 \text{ minutes}} \approx -1,272.73 \text{ feet per minute}
\]
### Summary of Findings:
1. **From 1.5 to 3 minutes: -6,000 feet per minute (decrease)**
2. **From 3 to 4.25 minutes: +4,400 feet per minute (increase)**
3. **Overall from 1.5 to 4.25 minutes: approximately -1,272.73 feet per minute (decrease)**
### Filling in the Statements
Now we can fill in the blanks based on your question:
1. **The altitude of the airplane:**
- **Decrease**
2. **Fill this blank with a number:**
- Based on the first interval of time, the most significant decrease noted is **6,000** feet per minute.
3. **Fill this blank with the rate of:**
