-5x-6=2y then....
y = -2.5x-3 Slope-Intercept form
Answer: 81% of the variance in dependent variable is explained by this correlation .
Step-by-step explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say
<em> </em>of the<em> </em>variance in Y is explained by Variable X.
Given: r= 0.90

So, 81% of the variance in dependent variable is explained by this correlation .
6 gallons in 4 1/2 seconds to travel 1/4 mile
Multiply through by 4
-------
The dragster will :
use 24 gallons in 18 seconds to travel 1 mile.
You have to make the lines congruent so it is 23by10
Using the sine rule:
sinx/37 = sin42/31
sinx = 37 x sin42/31
x = (i dont have a calulator but use inverse sign to get this answer)
