Question

Accepted Answer

### Question 1
# Brief Explanations:
In an experiment or graph, the dependent variable is what is being measured. Here, the graph shows temperature (on y - axis) as a function of month (x - axis) for two cities. So the dependent variable is the one that depends on the independent variable (month), which is temperature.
# Answer:
The dependent variable is temperature (°F).

### Question 2
# Brief Explanations:
Looking at the y - axis label of the graph, it is labeled "Temperature (°F)". So the unit on the y - axis is degrees Fahrenheit (°F).
# Answer:
The units on the y - axis are degrees Fahrenheit (°F).

### Question 3
# Brief Explanations:
The legend of the bar graph shows two cities: New York (°F) and Sydney (°F). So these are the two cities being compared.
# Answer:
The two cities being compared are New York and Sydney.

### Question 4
# Brief Explanations:
We look at the bars representing New York's temperature (the black bars). We compare the heights of these bars for each month. The bar for July (and maybe August, but typically July is the peak for New York's summer) is the tallest among the New York bars.
# Answer:
New York has the highest average temperature in July (and/or August, but July is a common peak).

### Question 5
# Brief Explanations:
We look at the bars representing Sydney's temperature (the white bars) from August to December. From August to December, we can see that the height of the bars (temperature) generally increases (with some fluctuations, but overall a rising trend) as we move from August towards December.
# Answer:
The temperature in Sydney, Australia between August and December generally increases (shows an upward trend).

### Question 6
# Brief Explanations:
We look at the black bars (New York's temperature) and check which months have a height (temperature) below 50°F. By observing the graph, January, February, March, and maybe April (depending on the graph's scale) have temperatures below 50°F. From the visual, January, February, March seem to be clearly below 50°F.
# Answer:
New York experiences average temperatures below 50°F in January, February, and March (and possibly April).

### Question 7
# Brief Explanations:
To find the range, we calculate the difference between the maximum and minimum temperatures for each city. For New York, the minimum temperature (in winter months) is relatively low (e.g., around 30 - 40°F) and the maximum (in summer, July/August) is around 80 - 90°F. For Sydney, the minimum (in winter, June - August) is around 60 - 70°F and the maximum (in summer, December - February) is around 80 - 90°F. The difference (range) for New York is larger (e.g., 90 - 30 = 60°F approximately) compared to Sydney (e.g., 90 - 60 = 30°F approximately). So New York has a greater range as its temperatures vary more from winter to summer.
# Answer:
New York has a greater range in temperature throughout the year. Explanation: New York's temperatures are much lower in winter (e.g., 30 - 40°F) and higher in summer (e.g., 80 - 90°F), so the difference between its maximum and minimum temperatures (range) is larger than Sydney's, where winter temperatures are not as low (60 - 70°F) and summer temperatures are similar to New York's, leading to a smaller range.
