What are permutation and combination?

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.


Required number of  codes = 26 * 8 * 8 * 8 * 8 * 8
                                         = 851,968

A distribution is given as X ~ U(0, 12). Find P(x > 6). (Enter an exact number as an integer, fraction, or decimal.)

Answers

Answer:

Step-by-step explanation:

The value of P(x>6) is 1/5.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Given that A distribution is given as X ~ U(0, 12).

We need to find the value of  P(x > 6)

The probability density function of the uniform distribution is defined as:

f(x)=1/b-a, a<x<b

a=0 and b=12

f(x)=1/12 , 0<x<12

The required probability is P(x>6)

Now P(x>6)= [tex]\int\limits^2_6 {f(x)} \, dx[/tex]

P(x>6)=(12/12-6/12)

=1-1/2

=1/2=0.5

Hence, the value of P(x>6) is 1/5.

Step-by-step explanation:

Convert the inequality to an equation.

2x² - 5x = 12

2x² - 5x - 12 = 0

Factor by grouping.

(2x + 3)(x - 4) = 0

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

2x + 3 = 0

x - 4 = 0

Solve for x.

x = -3/2

x = 4

Use each root to create test intervals.

The solution consists of all of the true intervals.
