Answer: The answer can be 3.4, 3.5, 3.6, and even 3.7
Explain:
It is all because if you got an answer that you need to be between into it, you can start like this. For example: What number is between 3 and 4, well it's 3.5. So do that with the decimal, it's like the same thing.
What if it was between 3.4 and 3.6, than it's anywhere 3.51, like that, or 3.5, to make it simple.
I hope that was helpful

To determine the regression:
Intercept
= 131760.9563
Slope
The regression line equation
We then make a comparison of the slope of the equation to y = mx+c
slope of the equation = -1.2600
the y-intercept corresponds to when X = 0, thus:
y-intercept = 131760.9563
Yes, it is reasonable to interpret the y-intercept of the regression line, Using atmospheric pressure as an explanatory variable due to the fact that:
X is the independent variable and Y exists as the dependent variable.
Answer:
Perpendicular: 4, Parallel: -1/4
Step-by-step explanation:
The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.
First write the equation of the line in slope-intercept form
-x-4y=7
-4y=x+7
y=-(1/4)x-7/4;
The slope to the line is -1/4; Now find the slope of the perpendicular line;
-(-1/4)^-1 = 4
4
The slope of a line parallel to a line is the same as the given slope;
when we calculated the given slope, it was -1/4
The slope of the line parallel to this line is also -1/4
-1/4
