Worked Solution & Example Answer:A travel agent records the duration and cost of the 15 flights he sold on one day - OCR - GCSE Maths - Question 14 - 2020 - Paper 3
Step 1
The data for the final two flights is:
Answer
To plot the final two flights on the scatter diagram:
-
For the first flight:
- Duration: 210 minutes
- Cost: £130 Locate the point (210, 130) on the graph and plot it.
-
For the second flight:
- Duration: 100 minutes (1 hour 40 minutes is equal to 100 minutes)
- Cost: £80 Locate the point (100, 80) on the graph and plot it.
Step 2
Circle the most likely flight on the scatter diagram.
Answer
To identify the most likely flight that has been discounted:
Examine the plotted points on the scatter diagram. The flight that appears significantly lower in cost than others at a similar duration level is most likely the one discounted. Based on the plot, circulate the flight at approximately (100, 80) since it stands out as a lower cost for its duration.
