Question 1

A student records the temperature outside every hour for a day. The data is: 6am-55°F, 7am-57°F, 8am-60°F, 9am-65°F, 10am-70°F. What is the most reasonable prediction for the temperature at 11am?

Accepted Answer

74°F

Answer

The data shows a clear trend of the temperature increasing by 2, 3, 5, and then 5 degrees each hour. The rate of warming is accelerating. Continuing this warming trend, a temperature around 74°F or 75°F is the most logical prediction.

Question 2

A graph shows the population of deer in a forest over 20 years. The line on the graph goes up steadily for 10 years and then begins to fluctuate up and down around a certain level. What is the best interpretation of the data after year 10?

Accepted Answer

The deer population reached the carrying capacity of the forest.

Answer

When a population reaches its carrying capacity, the environment can no longer support continued growth due to limited resources like food and space. The population size will then tend to fluctuate around this limit.

Question 3

A table shows the results of an experiment testing the effectiveness of three different dish soaps on a greasy pan. Soap A left 2mg of grease, Soap B left 5mg, and Soap C left 1mg. Which conclusion is supported by this data?

Accepted Answer

Soap C is the most effective.

Answer

The most effective soap would be the one that removes the most grease, which means it leaves the least amount behind. Soap C left only 1mg, which is the lowest amount, making it the most effective in this test.

Question 4

A student measured the growth of a plant over five weeks and recorded the following heights: Week 1: 2 cm, Week 2: 4 cm, Week 3: 6 cm, Week 4: 8 cm, Week 5: 10 cm. What is the average weekly growth rate?

Accepted Answer

2 cm/week

Answer

The plant grows consistently by 2 cm each week (4-2=2, 6-4=2, etc.). Because the rate is constant, the average growth rate is 2 cm/week.

Question 5

A bar chart compares the average rainfall in four different cities. City A: 10 inches, City B: 45 inches, City C: 42 inches, City D: 25 inches. Which statement accurately compares the rainfall in City B and City A?

Accepted Answer

City B receives more than four times the rainfall of City A.

Answer

To compare the rainfall, divide the amount in City B (45 inches) by the amount in City A (10 inches). 45 / 10 = 4.5. This means City B receives 4.5 times the rainfall of City A, which is more than four times.
