Worksheet 1B - MATHEMATICS [FORMAL ASSESSMENT] 2.2 Determine the median of burglary/fire incidents over the five years. 2.3 Explain what the mean tells us about incidents of burglary/fire trends in South Africa over the five years.

The incidents are: $1145, 1981, 1203, 1579, 1050$.
Sorted list: $1050, 1145, 1203, 1579, 1981$.

Since there are 5 data points (an odd number), the median is the middle value.
The middle value is the $3^{\text{rd}}$ term in the sorted list.
The $3^{\text{rd}}$ term is 1203.

The median number of burglary incidents is $\boxed{1203}$.

Incidents in $2023 = 1579$
Incidents in $2024 = 1050$

$\frac{\text{Decrease}}{\text{Original Value}} \times 100\%$.

The percentage decrease in burglary/fire incidents from 2023 to 2024 is $\boxed{33.50\%}$.

3.2 The number of reported burglary or fire incidents increased by an average of 9% from 2024 to 2025. Using the number of incidents recorded in 2024, calculate and predict the number of incidents for 2025.

Incidents in $2024 = 1050$

Since the number of incidents must be a whole number, we round to the nearest whole number.

The predicted number of incidents for 2025 is $\boxed{1145}$.
