    Describe the trend of the graph above. - ProProfs

    Describe the trend of the graph above.

    • Positive correlation

    • Negative correlation

    • No correlation

    Correct Answer
    A. No correlation
    Explanation
    The graph above shows no correlation between the variables being measured. This means that there is no clear relationship or pattern between the two variables. As one variable increases, the other variable does not consistently increase or decrease. The data points are scattered randomly across the graph, indicating that there is no systematic relationship between the variables.

    Use Figure 2 to compare the life expectancy of the tree and beetle population.  What can be inferred from this chart? - ProProfs

    Use Figure 2 to compare the life expectancy of the tree and beetle population.  What can be inferred from this chart?

    • Beetles breed more slowly than trees.

    • The beetle population increases more rapidly than the tree population.

    • Trees will become extinct after 40 years.

    • The number of trees is greater than the number of beetles after 40 years.

    Correct Answer
    A. The beetle population increases more rapidly than the tree population.
    Explanation
    From Figure 2, it can be inferred that the beetle population increases more rapidly than the tree population. This is because the line representing the beetle population has a steeper upward slope compared to the line representing the tree population. This indicates that the beetles are reproducing and increasing in number at a faster rate than the trees.

    Describe the trend of the graph above. - ProProfs

    Describe the trend of the graph above.

    • Positive correlation

    • Negative correlation

    • No correlation

    Correct Answer
    A. Negative correlation
    Explanation
    The graph above shows a negative correlation. This means that as one variable increases, the other variable decreases. In other words, there is an inverse relationship between the two variables. As the values on the x-axis increase, the values on the y-axis decrease. This can be observed by the downward slope of the line on the graph.

    What is the dependent variable?

    • Miles per gallon

    • Weight of Car

    • Comparing Car Weights

    Correct Answer
    A. Miles per gallon
    Explanation
    The dependent variable in this context refers to the variable being measured or observed, which is affected or influenced by other variables. In this case, the dependent variable is "Miles per gallon." This means that the number of miles a car can travel per gallon of fuel is being measured, and it is influenced by factors such as the weight of the car, engine efficiency, and driving conditions.

    Describe the trend of the graph above.

    • Positive correlation

    • Negative correlation

    • No correlation

    Correct Answer
    A. Positive correlation
    Explanation
    The graph above shows a positive correlation. This means that as one variable increases, the other variable also increases. The relationship between the variables is positive, indicating that they move in the same direction.

    Rate this question:

  • 8. 
    What is the independent variable? - ProProfs

    What is the independent variable?

    • Miles per Gallon

    • Weight of Car

    • Y-axis

    Correct Answer
    A. Weight of Car
    Explanation
    The independent variable in a study or experiment is the variable that is manipulated or changed by the researcher. In this case, the weight of the car is the independent variable because it can be controlled and varied by the researcher. The researcher can select different weights for the car and observe how it affects the other variables, such as miles per gallon. The weight of the car is not dependent on any other variable in this scenario, hence making it the independent variable.

    Describe the trend of the above graph.

    • Positive trend

    • Negative trend

    • No correlation

    Correct Answer
    A. Negative trend
    Explanation
    The trend of the graph is negative, indicating a downward movement or decrease over time. This means that as the independent variable increases, the dependent variable decreases. There is an inverse relationship between the two variables, suggesting a negative correlation.

    Rate this question:

  • 10. 
    What is the independent variable? - ProProfs

    What is the independent variable?

    • Years

    • Beetles

    • Trees

    • Beetle/tree life

    Correct Answer
    A. Years
    Explanation
    The independent variable in this scenario is "years". This means that the variable being studied or manipulated is the number of years. In other words, the researchers are interested in how the passage of time affects or influences the other variables in the study, such as beetles or trees. By studying the changes that occur over different years, they can observe any patterns or trends that may emerge.

    • Number of trees

    • 30,000

    • Trees Needed To Support the Beetle Population

    Correct Answer
    A. Number of trees
    Explanation
    The independent variable in this question is the number of trees. This means that the number of trees is the factor that is being manipulated or changed in the experiment. The question is asking which option represents the independent variable, and the correct answer is "number of trees".

  • 12. 
    What is the beetle population after 20 years? - ProProfs

    What is the beetle population after 20 years?

    • 10 million

    • 20 million

    • 30 million

    • 40 million

    Correct Answer
    A. 20 million
    Explanation
    The beetle population is projected to reach 20 million after 20 years. This can be inferred from the given options, where the second option states that the population after 20 years is 20 million. Therefore, based on the information provided, 20 million is the correct answer for the beetle population after 20 years.

    Extrapolate to a car weighing 4500 lbs - ProProfs

    Extrapolate to a car weighing 4500 lbs

    • 50 mpg

    • 30 mpg

    • 15 mpg

    Correct Answer
    A. 15 mpg
    Explanation
    The answer of 15 mpg suggests that when extrapolating the car's fuel efficiency to a weight of 4500 lbs, it is estimated to have a fuel efficiency of 15 miles per gallon. This implies that the heavier the car gets, the less fuel efficient it becomes, as it requires more energy to move the increased weight.

    Regarding Figure 1, which of these statements is incorrect? - ProProfs

    Regarding Figure 1, which of these statements is incorrect?

    • A greater number of trees indicates a higher beetle population.

    • The number of beetles in an area is dependent upon the number of trees in that area.

    • There is a positive correlation between the number of beetles in an area and the number of trees.

    • There appears to be no correlation between the number of trees in an area and the beetle population.

    Correct Answer
    A. There appears to be no correlation between the number of trees in an area and the beetle population.
    Explanation
    The given answer is incorrect because the figure clearly shows that a greater number of trees indicates a higher beetle population. The graph shows a positive correlation between the number of trees and the beetle population, with an increase in the number of trees corresponding to an increase in the number of beetles. Therefore, the statement "There appears to be no correlation between the number of trees in an area and the beetle population" is incorrect.

    Which of the following statements is true regarding Figure 1? - ProProfs

    Which of the following statements is true regarding Figure 1?

    • The beetle population is the independent variable.

    • The number of trees is the depedent variable.

    • The beetle population is the depdent variable.

    • Botht the beetle population and the number of trees are independent variables.

    Correct Answer
    A. The number of trees is the depedent variable.
    Explanation
    The correct answer is that the number of trees is the dependent variable. This means that the number of trees is being influenced or affected by another variable, which in this case is the beetle population. The beetle population is the independent variable, as it is the variable that is being manipulated or changed in order to observe its effect on the number of trees. Therefore, the number of trees is dependent on the beetle population.
