Suppose that a die is rolled twice. What are the possible values that the following random variables can take on: (a) the maximu

Fiesta28 [93]

Answer:

See explanation

Step-by-step explanation:

Suppose that a die is rolled twice. Each time one of 6 numbers (1, 2, 3, 4, 5, 6) can be rolled.

A. the maximum value to appear in the two rolls is 6

B. the minimum value to appear in the two rolls is 1

C. the sum of the two rolls can vary from 2 to 12 (it can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

D. the value of the first roll minus the value of the second roll can very from -5 to 5 (-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5)

Here -5 can be obtained as 1 - 6 (1 on the first roll and 6 on thesecond roll), -4 can be obtained as 1 - 5 or 2 - 6 and so on.

Using Cramer’s Rule, what is the value of x in the system of linear equations below?

cluponka [151]

Answer:

x = 8 is the answer

Step-by-step explanation:

In order to find the solution of Equations using Cramer's rule

we shall find matrices

D= $\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right]$ =

$D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]$

l D l = Determinant formed by coefficient of variables

Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7

l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations

Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56

here x is given by $\frac{l D1 l}{l D l}$

x = $\frac{-56}{-7}$

x = 8
