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
$64 is 80% of $80. To find how many percent of $80 is $64. $64/$80 = 0.8 or 80%
To find how many percent of decrease, just subtract 80-64=16; $16/$80= 0.2 or 20%
Answer:
10/12 = 5/6
10/12 = 20/24
10/12 = (10*x)/(12*x) with x ≠ 0
The first letter can be any of 26. Each remaining letter can be any of the 25 that remain after the one before is deleted from consideration. Your number is
26·25^5 = 253,906,250
The GCF would be one and if you were to change the numbers 3,12,15 to fractions the I guess that would be one too
