Answer:
Interference for regression
Explanation:
Interference for regression is the most suitable statistical test to use to find out if there is any link between number of missed classes and the final test scores.
Because those two variables are related and student test score can be predicted using number of classes that are missed.
Answer:
option 4
Step-by-step explanation:
option 2 and 4 are the more closest options but option 2 is a graph function between the negative numbers, so the answer is option 4.
Answer:
The slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.
Step-by-step explanation:
From the line equation, let us take two points
Finding the slope between two points




As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be:

Thus, the slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.
we have

using a graph tool
see the attached figure
in the graph observe that
As x goes to negative infinity-------> f(x) decreases
and
As x goes to positive infinity-------> f(x) increases
therefore
the answer is
As x goes to negative infinity, f(x) goes to negative infinity, and as x goes to positive infinity, f(x) goes to positive infinity.
