Answer:
C
Step-by-step explanation:
This is because using the formula of area for shapes, you get this equation
A=2(wl+hl+hw)=2·(4·6+4·6+4·4)=128
Answer:
6=y
Step-by-step explanation:
5y + 6 = -3y +54
isolate y
+3y
8y +6 =54
subtract 6 to isolate y.
8y = 48
divide by 8 so y is alone w no coefficient other than 1
y=6
Answer:
10.488cm
Step-by-step explanation:
5²+6²=61
don't need to square root it because you need to square it again if you do
61+7²=110
square root of 110 is 10.4880885
answer is 10.4880885, but you can round it down if you need to.
Hope this helped! :^)
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
