I can help you with question 2.3.3. Unfortunately, the chart mentioned in question 2.3.2 is not visible in the image, so I cannot answer parts 2.3.2 (a) and (b).

Here are the calculations for 2.3.3:

2.3.3 a) Calculate the fan's BMI using the formula provided.

Identify the given values for weight and height.
Weight $= 105 \text{ kg}$
Height $= 1.73 \text{ m}$
Use the BMI formula
$\text{BMI} = \frac{\text{Weight (kg)}}{(\text{Height in m})^2}$ .
$\text{BMI} = \frac{105}{(1.73)^2}$
Calculate the square of the height.
$(1.73)^2 = 2.9929$
Substitute the squared height into the BMI formula and calculate.
$\text{BMI} = \frac{105}{2.9929}$ $\text{BMI} \approx 35.088$
The fan's BMI is approximately $\boxed{\text{35.09}}$ .

2.3.3 b) Determine how many full kilograms this fan must lose to reach a BMI of exactly 30.
Identify the target BMI and the fan's height.
Target BMI $= 30$
Height $= 1.73 \text{ m}$
Rearrange the BMI formula to solve for the target weight.
$\text{Weight (kg)} = \text{BMI} \times (\text{Height in m})^2$
Calculate the target weight for a BMI of 30.
$\text{Target Weight} = 30 \times (1.73)^2$ $\text{Target Weight} = 30 \times 2.9929$ $\text{Target Weight} = 89.787 \text{ kg}$
Calculate the difference between the current weight and the target weight.
Current weight $= 105 \text{ kg}$
$\text{Kilograms to lose} = \text{Current Weight} - \text{Target Weight}$ $\text{Kilograms to lose} = 105 \text{ kg} - 89.787 \text{ kg}$ $\text{Kilograms to lose} = 15.213 \text{ kg}$
Determine the number of full kilograms to lose.
The fan must lose $\boxed{\text{15 full kilograms}}$ .
