Answer:

b = 1

Step-by-step explanation:

-18+4b=7(4)+(7)-(6b)

-18+4b= 28 + (-42b)

4b-16=-42b+28

Add 42b to both sides.

4b-16+42b=-42b+28+42b

46b-18=28

Add 18 to both sides.

46b-18+18=28+18

46b=46

b= 46/46

b=1

10. Evaluate if: y = 4 and z = -2

Bas_tet [7]

Substitute with y = 4 and z = -2

= 4^2*(-2)/4 + 10

= 16*(-2)/4 + 10

= -32/4 + 10

= -8 + 10

= 2

Suppose the random variables X, Y, and Z have the following joint probability distribution. x y z f ( x , y , z ) 1 1 1 0.05 1 1

Airida [17]

Answer:

Determine the conditional probability distribution of X given that Y = 1 and Z = 2. Round your answers to two decimal places (e.g. 98.76).

answer:

Given that Y = 1 : 2/5

Given that Z = 2 : 3/5

Step-by-step explanation:

The conditional probability distribution of X F x | yz^( x )

Given that Y = 1

F x | yz . ( x | yz ) = 2/5

Given that z = 2

= 3/5

attached below is the detailed solution
