Answer:
The slope of this line is 1021.
Step-by-step explanation:
A regression line has the following format:
y = b + ax
In which a is the slope, that is, how much y changes with a variation of a single unit in x.
In this problem, our line is:
forest loss=7500+1021x
In which x is the number of years after 2000.
So the slope of this line is 1021.
It is b Bc if you actually look at the other one it don’t make sense
PEMDAS
2.5x + 0.1x = 2.6x
2.6x - 0.01x = 2.59x
<u>Answer-</u>
<em>A. strong negative correlation.</em>
<u>Solution-</u>
<u>Direction of a relationship</u>
- Positive- If one variable increases, the other tends to also increase. If one decreases, the other tends to also. It is represented by positive numbers(i.e 0 to 1).
-
Negative- If one variable increases, the other tends to decrease, and vice-versa. It is represented by negative numbers(i.e 0 to -1)
<u>Strength of a relationship</u>
- Perfect Relationship- When two variables are linearly related, the correlation coefficient is either 1 or -1. They are said to be perfectly linearly related, either positively or negatively.
- No relationship- When two variables have no relationship at all, their correlation is 0.
As in this case, correlation coefficient was found to be -0.91, which is negative and close to -1, so it is a strong negative correlation.
The answer is forty five.
