1. The given line l is a horizontal straight line parallel to the x-axis. For any two distinct points chosen on this line, the vertical coordinate remains constant, meaning the vertical rise (y₂ - y₁) is zero while the horizontal run (x₂ - x₁) is non-zero. Therefore, the slope is calculated as 0 divideRead more

    The given line l is a horizontal straight line parallel to the x-axis. For any two distinct points chosen on this line, the vertical coordinate remains constant, meaning the vertical rise (y₂ – y₁) is zero while the horizontal run (x₂ – x₁) is non-zero. Therefore, the slope is calculated as 0 divided by run, which gives a slope of 0.

  2. 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

  3. 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

  4. (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.

    (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%, showing relative proportions rather than actual elapsed times needed for questions (a) and (c).

    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.
