Answer:

A ∩ B = {3,9}

Step-by-step explanation:

Consider the completer question is "Stephanie is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is odd} and let B = {the sum of the number cubes is divisible by 3}. List the outcomes in A ∩ B.  Options : {1,3,5,7,9,11} , {1,3,9} , {3,9}, {3,9,12}"

It is given that Stephanie is playing a board game and rolls two number cubes.

Let A = {The sum of the number cubes is odd}

A = {3,5,7,9,11}

B = {The sum of the number cubes is divisible by 3}

B = {3,6,9,12}

We need to find the outcomes in A ∩ B.

It means we need to find the common elements of A and B.

A ∩ B = {3,9}

Therefore, the required set of values is {3,9}.

Answer:

A ∩ B = {3, 9}

Step-by-step explanation:

First we find the possible values for the set A.

By launching the number cubes you can only get numbers from 1 to 6

You can get:

A = \{3, 5, 7, 9, 11\}

For set B you can get:

B = \{3, 6, 9, 12\}  <em> The numbers that are divisible by 3</em>

The set A ∩ B will be formed by the elements that are in A and are also in B. In this case they are: the odd numbers that are divisible by 3

Finally we have that:

A ∩ B = {3, 9}

mamaluj [8]

Answer: The test contains 10 three-point questions and 14 five-point questions.

Step-by-step explanation:

Let x represent the number of 3-point questions.

Let y represent the number of 5-point questions.

The maths test consists of 24 questions. This means that

x + y = 24

Each question is worth either 3 points or 5 and the test is worth 100 points. This means that

3x + 5y = 100 - - - - - - - - - - -1

Substituting x = 24 - y into equation 1, it becomes

3(24 - y) + 5y = 100

72 - 3y + 5y = 100

- 3y + 5y = 100 - 72

2y = 28

y = 28/2 = 14

Substituting y = 14 into x = 24 - y , it becomes

x = 24 - 14 = 10
