Classify each number according to which sets of numbers it belongs in:

True [87]

Answer:

Natural, integer, rational: 10, 9, $3(12-\frac{2}{2})$

Integer, rational: -6

Rational: 3.7, 3.3333333

Irrational: $\pi$ , 1.41421356

Step-by-step explanation:

Given numbers:

$10,\pi, -6, 3.3333333333, 9, 3.7, 3(12-2/2),1.41421356$

To classify them in natural integer, whole rational or irrational numbers.

Solution:

Natural numbers are whole numbers stating from 1.

{1,2,3,4,5,6..........}

Whole numbers are integers starting from 0.

{0,1,2,3,4,5...........}

Integers are all real numbers that do not include decimals or fractions.

{.............-4,-3,-2,-1,0,1,2,3,4.........}

Rational numbers are those numbers which can be represented as fraction of whole numbers. For example:

$-1.5=-\frac{3}{2}$

$0.1111.....=\frac{1}{9}$

$5=\frac{5}{1}$

Irrational numbers are those numbers which cannot be represented as simple fractions.

<em>Based on the above definitions, we can classify numbers.</em>

1) 10

Natural, Integer, Rational

2) $\pi$

Irrational

3) -6

Integer, Rational

4) 3.33333333333

Rational

5) 9

Natural, Integer, Rational

6) 3.7

Rational

7) $3(12-\frac{2}{2})=3(12-1)=3(11)=33$

Natural, Integer, Rational

8) 1.41421356

andreyandreev [35.5K]

Answer and explanation:

Given : Suppose that a die is rolled twice.

The sample space form is

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

To find : What are the possible values that the following random variables can take on

(a) The maximum value to appear in the two rolls;

The possible values are 1; 2; 3; 4; 5; 6.

b) The minimum value to appear in the two rolls;

The possible values are 1; 2; 3; 4; 5; 6.

c) The sum of the two rolls;

The possible values are 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.

The possible values are -5; -4; -3; -2; -1; 0; 1; 2; 3; 4; 5.
