  2. We can calculate frequency using specific formulas that take into account other related quantities like time period, wave speed, and wavelength. These formulas help us understand the behavior of waves and how they propagate through space. Formula 1: Frequency formula based on time period (T): f = 1 T.

  3. In the frequency formula, f = 1/T, T is the time period. T refers to the time to complete one cycle (in seconds). Time period is inversely proportional to the frequency. The frequency formula is used to find the frequency of the wave.

  4. Example: A biased coin is flipped 500 times. The relative frequency of landing on heads is calculated to be 0.65. How many times did the coin land on heads? Apply the formula for relative frequency, identifying the relative frequency and number of trials from the question: 0.65 =

  5. Question 4: The frequency polygons show the amount of time that 30 students in year 7 and 30 students in year 11 spent on their last maths homework. Compare the time spent on homework by the year 7s and the year 11s.

  6. These questions require working out to be shown. Failure to show sufficient working out is likely to result in no marks being awarded, even if the final answer is correct.
