Answer:
x ∈ (-3, -1)
Step-by-step explanation:
In the graph, the vertical axis represents the y-value, while the horizontal axis represents the x-value.
y < 0 (y smaller than zero) happens in the region where the graph is below the horizontal axis.
Only by looking at the graph, we can see that y < 0 (the graph is below the horizontal axis) for the values of x in the interval (-3, -1)
Then all the values of x such that y < 0 are:
x ∈ (-3, -1)

Answer:
d. f(2) < g(2)
Step-by-step explanation:
The attached table and graph shows how the functions relate for the various x-values of interest. The true statement is ...
f(2) < g(2)
-3 < 0
Estimate: 4x980= 3920
Actual Product: 3916
Answer:
The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.
The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.
Step-by-step explanation:
The simple linear regression line is used to determine the changes in the dependent variables when the independent variable is changed.
The general form of the simple linear regression line is:

The simple linear regression model for the reaction time of a certain chemical process based on the temperature (°F) in the chamber in which the reaction takes place is:

Here,
<em>y</em> = reaction time (in hours)
<em>x</em> = temperature (°F)
Compute the expected change in reaction time for a 1°F increase in temperature as follows:


The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.
Compute the expected change in reaction time for a 8°F increase in temperature as follows:


The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.
