Answer:
The correct option is b.
Step-by-step explanation:
It is given that y-axis of a scatter plot represents the property taxes and x-axis represents the sizes of their homes, in square feet.
The equation of least squares regression line is
We have to find the property taxes to be for a 1300-square-foot home in the area.
Substitute x=1300 in the given equation.
The property taxes for a 1300-square-foot home in the area is $2473.30. Therefore the correct option is b.

Answer:
B. -6 does not belong to the domain but belongs to the range of f(x).
Step-by-step explanation:
We have the function, .
So, the domain of the function is obtained when i.e.
That is, the domain is {x | x≥ 7}.
Now as we have,
→
→
→
→
.
That is,
Thus, the range of the function f(x) is {y | y≤ 1}.
Thus, we can see that,
-6 does not belong to the domain but belongs to the range of f(x).
<h3>Answer: 95 degrees</h3>
=======================================================
Explanation:
I recommend drawing it out to see what's going on. See the drawing below.
In the diagram, both angles are in the northeast corner of their four-corner configurations. They are both congruent corresponding angles. So that's why the second angle is also 95 degrees.
Side note: we could replace "northeast" with any of the other directions on the compass (such as southwest). All that matters is that they are in the same configuration.
