Part A

Question

Rohan made an error in his model. Explain his error Include the correct grouping for model.

Part B

what is the quotient of 1.38 divide by 3 written as a decimal ?

Answer 1

Part A: Rohan's Error in His Model

While the specifics of Rohan's error are not provided, common errors in modeling could include incorrect assumptions, faulty calculations, or inappropriate grouping of data.

For example, if Rohan was attempting to model a phenomenon involving ratios, proportions, or data points that require categorization, he might have grouped dissimilar items together, leading to inaccurate conclusions.

To illustrate, if Rohan was modeling sales data and grouped together all products regardless of their category (e.g., electronics, clothing, food), he would likely miss critical insights about trends specific to each category. The correct grouping would involve separating the data by relevant categories to ensure that trends can be accurately analyzed within each group.

Part B: Quotient of 1.38 Divided by 3 as a Decimal

To calculate \( 1.38 \div 3 \):

1. Perform the division:
   \( 1.38 \div 3 = 0.46 \)

Thus, the quotient of \( 1.38 \div 3 \) written as a decimal is \( 0.46 \).
