Answer:
a. always
Step-by-step explanation:
In a simple linear regression, the slope measures the steepness of the linear relationship between the two variables, it ranges from (-∞ to +∞ ) while the correlation coefficient measures the tightness of the linear relationship between the two variables, it ranges from (-1 to +1 ).
So the correlation coefficient and the slope will always have the same sign though their values might differ.

This equation in standard form is 4x - 3y = 3
<h3>How to rewrite this equation in standard form?</h3>
The equation is given as
y= 4 over 3x - 2 over 3
Rewrite properly as:
y = 4/3x - 2/3
Multiply through 3by
3y = 4x - 3
Subtract 4x from both sides
-4x + 3y = -3
Multiply through by -1
4x - 3y = 3
Hence, this equation in standard form is 4x - 3y = 3

Answer:
15.3 in
Step-by-step explanation:
The lengths are proportional, so you can write ...
model/train = 3 in/(35 ft) = (x in)/(178.5 ft)
Multiplying by 178.5 ft, we get ...
x in = (3 in)(178.5/35) = 15.3 in
The length of the model is 15.3 inches.
