You're on a roll — 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. Step 1: Identify the given values for weight and height. Weight = 105 kg Height = 1.73 m Step 2: Use the BMI formula: BMI = Weight (kg)(Height in m)^2. BMI = (105)/((1.73)^2) Step 3: Calculate the square of the height. (1.73)^2 = 2.9929 Step 4: Substitute the squared height into the BMI formula and calculate. BMI = (105)/(2.9929) BMI ≈ 35.088 The fan's BMI is approximately 35.09. 2.3.3 b) Determine how many full kilograms this fan must lose to reach a BMI of exactly 30. Step 1: Identify the target BMI and the fan's height. Target BMI = 30 Height = 1.73 m Step 2: Rearrange the BMI formula to solve for the target weight. Weight (kg) = BMI × (Height in m)^2 Step 3: Calculate the target weight for a BMI of 30. Target Weight = 30 × (1.73)^2 Target Weight = 30 × 2.9929 Target Weight = 89.787 kg Step 4: Calculate the difference between the current weight and the target weight. Current weight = 105 kg Kilograms to lose = Current Weight - Target Weight Kilograms to lose = 105 kg - 89.787 kg Kilograms to lose = 15.213 kg Step 5: Determine the number of full kilograms to lose. The fan must lose 15 full kilograms. What's next?
