A scatter plot is made to model the number of grams of fat in different portions of fried shrimp. The data used for the scatter plot are shown in the table:

| Number of portions | 5 | 3 | 8 | 6 | 1 | 4 |
|--------------------|---|---|---|---|---|---|
| Number of grams of fat | 45 | 27 | 72 | 54 | 9 | 36 |

What does the slope of the model represent?

A. The number of fried shrimp having one gram of fat
B. The number of grams of fat in each portion of fried shrimp
C. The original number of portions of fried shrimp
D. The price of each portion of fried shrimp



Answer :

To determine what the slope of the model represents, let's analyze the problem step by step.

1. Understanding the Data and Scatter Plot:
- We have a set of values representing the number of portions of fried shrimp and the corresponding number of grams of fat.
- The data table is as follows:
[tex]\[ \begin{tabular}{|c|c|c|c|c|c|c|} \hline Number of portions & 5 & 3 & 8 & 6 & 1 & 4 \\ \hline Number of grams of fat & 45 & 27 & 72 & 54 & 9 & 36 \\ \hline \end{tabular} \][/tex]

2. Linear Relationship:
- The relationship between the number of portions [tex]\(x\)[/tex] and the number of grams of fat [tex]\(y\)[/tex] can be modeled using a simple linear regression equation of the form [tex]\(y = mx + b\)[/tex], where [tex]\(m\)[/tex] is the slope and [tex]\(b\)[/tex] is the y-intercept.

3. Interpreting the Slope:
- The slope [tex]\(m\)[/tex] indicates the rate of change of [tex]\(y\)[/tex] with respect to [tex]\(x\)[/tex]. In this context, it represents how many grams of fat change for each additional portion of fried shrimp.

4. Given the Slope Value:
- From the given answer, the slope [tex]\(m\)[/tex] has been determined to be [tex]\(9.000000000000002\)[/tex].

5. Conclusion:
- This value for the slope suggests that for each additional portion of fried shrimp, the amount of fat increases by 9 grams.

Therefore, the correct interpretation of the slope in this context is:

The number of grams of fat in each portion of fried shrimp.

Hence, the correct answer is:
The number of grams of fat in each portion of fried shrimp.
