Question

The graph shows the data points in the table and the exponential regression model associated with the data. A 2-column table with 5 rows. The first column is labeled days after treatment with entries 2, 4, 6, 8, 10. The second column is labeled number of weeds with entries 100, 26, 6, 2, 1. A graph shows days after treatment labeled 1 to 11 on the horizontal axis and number of weeds on the vertical axis. A line shows a downward trend. Based on the graph of the regression model, which is true? The number of weeds is decreasing by a multiplicative rate. The number of weeds is increasing by a multiplicative rate. The number of weeds is decreasing by an additive rate. The number of weeds is increasing by an additive rate.

Answer 1

The number of weeds is decreasing by a multiplicative rate.

Step-by-step explanation:

The graph shows a downward trend in the number of weeds as the days after treatment increase. Based on the graph of the regression model, the number of weeds is decreasing by a multiplicative rate.

In an exponential decay model, the value decreases or decays at a constant percentage for each increment of the independent variable. In this case, as the days after treatment increase, the number of weeds decreases by a certain percentage each time.

For example, let's consider the data points in the table. From day 2 to day 4, the number of weeds decreases from 100 to 26. It can be observed that the value is not decreasing by a constant amount but rather by a percentage. This indicates that the number of weeds is decreasing by a multiplicative rate.

Answer 2
