The answer is C because when you divide it out you get 6
Answer:
SD = 2x
UD = x
Step-by-step explanation:
The hypotenuse of a 30-60-90 triangle is 2 times the length of the shorter leg.
SU is the shorter leg = x
So, SD = 2x
The longer leg of a 30-60-90 triangle is times the shorter leg.
So, UD = x
Answer:
y = three-halves x minus 3
Step-by-step explanation:
Subtract 3x from both sides of the original equation.
-2y = -3x +6
Divide by -2
y = 3/2x -3
Answer:
1c 2b 1d
Step-by-step explanation:
did the math
Solution :
From the given equation :
E[ E (X|Y) ] = E (X)
a). Then,
E[ E [ X|Y,Z] | Z] = E [ X|Z ]
---- True
E [ E [ X|Y ] | Z ] = E [ X|Z ]
---- False
E [E [X | Y,Z ]] = E [X|Y ]
---- False
b). Th quantity E [ g (X,Y) | Y,Z ] is ,
- A random variable ----- True
- A number ----- False
- A function of (X,Y) ----- False
- A function of (Y,Z) ----- True
- A function of Z only ------- False
