Instructor Guidance Example Week 2 Written Assignment Paper

Students, you are perfectly welcome to format your math work just as I have done in these examples. However, the written parts of the assignment MUST be done in your own words. You are NOT to simply copy my wording into your posts! [The introductory paragraph must be written by each individual student and the content will vary depending on what the student decides to focus on in the general information of the topic.]

On page 151 of our textbook we find the formula for Body Mass Index or BMI as follows: BMI = 703W / H^2 Where W = one’s weight in pounds, and H = one’s height in inches. We are asked to calculate four intervals based on our own height.

My height is 67.25 inches. The specified intervals include three compound “between” inequalities, and one regular inequality. Everywhere “BMI” shows up in the inequalities I will substitute the formula and solve the inequality for W to specify the weight ranges which fit each category for my height. The first interval shows who might have a longer life span than average. The compound inequality for this is: 17

H

17 4522.5625 / 703 4522.5625 / 703. Calculating these bounds provides the weight interval for a longer-than-average lifespan.

I will proceed with similar steps to derive the second, third, and fourth weight intervals, substituting respective BMI boundary values and simplifying accordingly. The second interval corresponds to BMI between 23 and 25, indicating a normal weight range. The third interval indicates overweight, with BMI between 25.1 and 29.9. The fourth interval indicates obesity, with BMI of 30 or above. I will methodically substitute, multiply, and divide to find the numerical bounds for each category for my height.

Expressing these in set notation, for example, the probably not overweight category: X = {w | 148

In conclusion, calculating BMI intervals based on height involves algebraic manipulation and substitution of the BMI formula. These calculations provide insight into different weight categories relative to height, aiding in understanding health implications. Accurate determination of these ranges can assist individuals in evaluating their weight status and making informed lifestyle choices.

Paper For Above instruction

Body Mass Index (BMI) is a widely used measure to categorize weight status in relation to height, serving as an essential tool for health assessment. The BMI formula, as given in our textbook on page 151, is BMI = 703W / H^2, where W is weight in pounds, and H is height in inches. By analyzing BMI, health professionals and individuals can understand potential health risks associated with underweight, normal weight, overweight, and obese categories. This paper explores how to calculate BMI-based weight intervals for an individual with a specific height (67.25 inches), illustrating the algebraic process involved, and interpreting the resulting intervals within the context of health.

The first step involves understanding the BMI categories and formulating inequalities to find corresponding weight ranges. For example, the interval indicating a potential longer lifespan corresponds to BMI between 17 and 22. Substituting the BMI formula, we derive the inequalities: 17

Given that H = 67.25 inches, its square (H^2) equals approximately 4522.56. Plugging this into the inequalities, we get:

17 4522.56 / 703 4522.56 / 703.

Calculating these bounds yields:

W > (17 * 4522.56) / 703 ≈ 109.1 lbs

W

Thus, for this height, individuals weighing between approximately 109.1 lbs and 141.5 lbs might have a longer lifespan than average.

Similarly, the normal weight range corresponds to BMI values between 23 and 25, leading to inequalities:

23

Multiplying through by H^2, we obtain:

23H^2

Substituting H^2 ≈ 4522.56, the bounds are:

W > (23 * 4522.56) / 703 ≈ 148.0 lbs

W

Individuals within this weight range for height 67.25 inches are likely to be within a normal weight category, with lower risk of weight-related health issues.

The overweight category spans BMI values from 25.1 to 29.9. Applying the same approach:

25.1 4522.56 / 703 4522.56 / 703.

Calculating bounds:

W > (25.1 * 4522.56) / 703 ≈ 161.5 lbs

W

Individuals weighing between approximately 161.5 lbs and 192 lbs are considered overweight for this height.

The obesity threshold begins at BMI 30, leading to:

W ≥ 30 * 4522.56 / 703 ≈ 193.0 lbs.

Individuals weighing 193 lbs and above are categorized as obese, which could pose significant health risks and indicate the need for lifestyle modifications.

These calculations demonstrate how algebraic manipulation of the BMI formula allows precise determination of weight categories tailored to specific heights. Recognizing these thresholds can motivate health-conscious decisions and early intervention to reduce health risks associated with excessive weight.

In conclusion, the process of deriving BMI-based weight intervals involves substitution, multiplication, and division, culminating in concrete weight ranges corresponding to health categories. Applying these methods to individual height data enhances understanding of personal health status and guides lifestyle choices aimed at achieving optimal well-being.
