Step-by-step explanation:
2.4 (-1/2)
=2.4×(-0.5)
=-1/2
Answer:
She took it off at 100 (because of the y-intercept) and it will last 20 hours because of where the line meets the x-axis.
<u>Given</u>:
Given that the graph of the regression model.
We need to determine the type of the best - fitting regression model.
<u>Model of the graph:</u>
From the graph, it is obvious that the points in the graph does not follows a straight line and thus the graph is not a linear model.
Also, from the graph, we can see that the points in the graph follows a curve pattern.
This curve pattern in the graph indicates that the graph follows an exponential curve.
Therefore, the best - fitting regression model for the given data plot is exponential model.
Hence, Option C is the correct answer.
$9.95 / 5 grapes = C / 4 grapes or 9.95:5 and C:4
