<h2>
Answer:</h2>
Option: C is the correct answer.
C) The equation is y = 2x, and the height is 40 inches.
<h2>
Step-by-step explanation:</h2>
We could clearly observe that the line of best fit passes through the point (0,0) and (20,40)
We know that the equation of a line passing through point (a,b) and (c,d) is calculated by the help of the formula:
Here we have:
(a,b)=(0,0) and (c,d)=(20,40)
Hence, the equation of line of best fit is:
Hence, the equation is:
y=2x
Also when x=20 we have:
y=40
Answer:
=−8x2+35x
Step-by-step explanation:
multiply first
Answer:
1.9
Step-by-step explanation:
First step would be to separate r from t
Then just insert the numbers
Answer:
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
Step-by-step explanation:
Assuming the following options:
A. there is a positive correlation between X and Y
B. there is a negative correlation between X and Y
C. if X is increased, Y must also increase
D. if Y is increased, X must also increase
E. none of the above
If we want a model 
where m represent the lope and b the intercept
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
