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
Its 7/20 because 35% as a fraction is 35/100 and u divided 35 by 5 and get 7 as your top number and divided 100 by 5 and get 20 for your bottom number
X=-3\7 its a negative fraction
1.If AC = 5x + 2 and BD = 2x + 20, find BD. 5x+2=2x+20 D BD=216)+20=32 ... 5. In the accompanying diagram, ABCD is a rectangle. E is a point on CD:
