The sides of a backgammon die are marked with numbers 2,4,8,16,32 and 64. Describe an outcome that has a probability of 2/3
Cloud [144]
The probability 2/3 means that there are 2 events we are interested in (which probability to happen we calculate) and there are 3 total events that may happen.
The probability 2/3 is equal to the probability 2/3*2/2=4/6.
An possible outcome would be : The probability that the side of the backgammon can be divided with 8 (there are 4 possibilities: 8, 16, 2 and 64).

The stem & leaf show demonstrates that 0.55 for both the data is indeed a reasonable value.

The probable outlier is the data value 0.76.

The variability of the techniques is relatively large.

It show isn't symmetrical and seems to be optimistic.

Matrix A is said to be involutory if A2 = I. Prove that a square matrix A is both orthogonal and involutory if and only if A is
goblinko [34]

Answer:

4 · 1/4 (I-0) = (A-0)∧2

see details in the graph

Step-by-step explanation:

Matrix A is expressed in the form A∧2=I

To proof that Matrix A is both orthogonal and involutory, if and only if A is symmetric is shown by re-expressing that

A∧2=I in the standard form

4 · 1/4 (I-0) = (A-0)∧2

Re-expressing

A∧2 = I as a graphical element plotted on the graph

X∧2=I

The orthogonality is shown in the graphical plot displayed in the picture. Orthogonality expresses the mutually independent form of two vectors expressed in their perpendicularity.

you distribute the 4 by multiplying it with the variables within the parenthesis.

(2x-6)+(4x-3)

you can loose the parenthesis and group common factors together.

2x+4x-6-3

add
