The ramp at a loading dock rises 2.5 metres over a run of 4 metres. Find the slope of the ramp.
The formula for the slope of an inclined surface is Rise divided by Run. Here, the vertical rise is given as 2.5 metres and the horizontal run is given as 4 metres. Dividing the rise by the run yields slope = 2.5 / 4. Multiplying the numerator and denominator by 2 gives 5/8, which equals 0.625. HencRead more

See lessThe following diagrams represent ski hills. Rank the hills in order of their steepness, from least to greatest.
Steepness is determined by the slope, calculated as vertical rise divided by horizontal run. For Hill A, slope = 60/70 ≈ 0.857. For Hill B, slope = 60/110 ≈ 0.545. For Hill C, slope = 80/100 = 0.800. Comparing these values shows that Hill B is the least steep, followed by Hill C and Hill A is the stRead more

See lessA triathlon is an endurance race consisting of swimming 3.8 km, cycling 180 km and running 42.2 km. Athletes compete for the fastest overall time, completing each segment in that order. The following table shows the finish time of 3 athletes in each segment. (i) What is a suitable representation of this data—a stacked bar chart or a 100% stacked bar chart? Why do you think so? (ii) Suppose a 100% stacked bar chart is drawn. Which of the following question(s) can be answered by looking at just that chart: (a) Who finished the race first? (b) Approximately what fraction of their race time did Athlete 1 spend cycling? (c) Which athlete took the longest for running?
(i) A regular stacked bar chart is much more suitable because triathlon ranking depends entirely on the absolute total time taken to complete all three segments, which total bar lengths clearly display. (ii) Only question (b) can be answered. A 100% stacked bar chart normalizes each total to 100%, sRead more

See lessIndividual project: Do at least one of the following. (i) Recall the previous day and fill in the approximate time spent lying down, sitting and standing/moving around, etc. Ask at least 2 of your family members about their day and fill it in. Alternatively, you can choose to track just your own body-state for any one of the weekdays, Saturday and Sunday. Visualise it using a stacked bar chart. Discuss with your class how you arrived at the estimated time spent in each state. (ii) Visualise your family’s monthly expenditure using a 100% stacked bar chart. (a) First, identify the expense categories in your family budget. (b) Discuss with your family members to decide how you will collect and organise the data. (c) Collect expense data for at least 3 months. (d) Represent the data in a 100% stacked bar chart, with each bar showing how the total monthly expenditure is divided across the different categories. (e) Finally, write your observations and inferences based on the chart.
Choosing project (i), track daily 24-hour routines across three individuals: for instance, recording 8 hours lying, 10 hours sitting and 6 hours moving. In a stacked bar chart, represent each person along one axis while stacking their category hours sequentially up to 24 hours. This clearly illustraRead more
Choosing project (i), track daily 24-hour routines across three individuals: for instance, recording 8 hours lying, 10 hours sitting and 6 hours moving. In a stacked bar chart, represent each person along one axis while stacking their category hours sequentially up to 24 hours. This clearly illustrates both individual lifestyle differences and the fixed daily total for each family member.

I notice that sensory (seeing and hearing) and movement-related disabilities form the vast majority across every age bracket. The elderly group (60+) displays a noticeably larger proportion of visual and auditory impairments compared to children. I wonder if aging biological factors explain this trend. We can infer that healthcare policies must prioritize mobility aids and vision-hearing care heavily for senior populations.
