Question

Alexa is training for a 10K race. For each of her training runs, she recorded the distance she ran and the time she ran. She made a scatter plot of her data and drew a trend line. Use the trend line to predict how long it would take Alexa to run 4.5 miles.

  1. 40 minutes
  2. 45 minutes
  3. 35 minutes
  4. 42 minutes

The correct answer is: 45 minutes


    For a distance of 4.5 miles, the trend line shows a time of 45 minutes. So, it will take Alexa about 45 minutes to run 4.5 miles.

      
      
      
      
      
      
    On x axis the graph has distance in miles and on y axis times in minute.
    For 1 mile alexa took 7.5 minute
    for 2 miles she took 15 minutes
    Similarily the trend of graph is clearly depicting the time taken for alexa to cover a distance of 4.5 mile is 45 minutes .

    The scatter plot shows David’s height at various ages. Choose the right answer that describe the type of association between David’s age and his height.

    The corerect option is (c)
    Reason :
    As the height of David increases with increase in his age , the graph is going upward as both the variable are increasing so it is a case of positive association and since there is almost constant change in both the variable it is shows linear relationship also
