A person's age and height

Step-by-step explanation:

Required

Select which do not represent proportionality

Proportionality exists when a unit rate can be calculated.

For instance:

- If 2 litres of gas is $2, then the unit rate is $1 per litre

- If an employee is paid $100 for 5 days, then the unit rate is $20 daily

- If 5 movie tickets cost $50, then the unit rate is $10 per movie

The above scenario are used to describe options (2 - 4) because they can be expressed in unit rates.

However, this is not the same for age and height because age is not a function of height and height is not a function of age. In other words, they can not be expressed in proportions.

So, option (a) is not a situation of proportionality.
