From what I recall, just set both the equations equal to each other
6x=5x+7
6x=5x+7
-5x -5x
1x=7
x=7
Then just plug in what you found.
y=6(7)
y=42
y=5(7)+7
y=35+7
y=42
42=42
Thus, you know your answer is correct.
Answer:
b = r(sy/sx)
Step-by-step explanation:
The sign of the slope Coefficient and the correlation are the same because both the slope and correlation Coefficient evaluates the changes in one variable with respect to the other . A decrease in y as x increases will result in a negative slope value and also a negative correlation Coefficient. While increase in x which results in the increase in y imvariable will result in a positive correlation Coefficient value and r value.
Slope, b = correlation Coefficient,r (Sy /Sx)
Sx = standard deviation of x values
Sy = standard deviation of Y Values
Answer:
3,400
Step-by-step explanation:
X = 11
angle LKM = angle KLM = angle LMK because it is an equilateral triangle
180/3 = 60
60=3x-27
60-27=3x
33=3x
x=11
