Given the following Venn diagram, choose the correct set for M UN

Reil [10]

Answer:

Third choice: {3, 4, 6, 7, 9}

Explanation:

Please, find the Venn diagram attached.

You have to find the set that represents the union of the set M and N (M ∪ N). That is a set with the elements that belong either to set M or set N.

The elements that belong to the set M are the numbers inside the circle M: 3, 4, 7 and 9.

The elements that belong to the set N are the numbers inside the circle N: 4, 6 and 7.

The complete list of the numbers in the union set is 3, 4, 6, 7, and 9, as you must not repeat the elements that belong to both sets.

So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.

What is the missing value?

Drupady [299]

Answer:

I believe that the missing value is 5, y=5

Step-by-step explanation:

1st since you can see in the ordered pair that 8 is in the x place that means 8 is the x value so what you can do is rewrite the equation to look like this: 5(8)-2y=30

2nd solve for y

5(8)-2y=30

40-2y=30

-40. -40 -subtract 40 on both side

-2y=-10

÷-2. ÷-2 -divide -2 on both sides

y=5

marissa [1.9K]

Answer:

There are 9 teams possible each having 14 third-graders, 20 Fourth-graders, 22 Fifth-graders

Step-by-step explanation:

126 third-graders

180 fourth-graders

198 fifth-graders

Find the highest common factor of 126, 180, 198

Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.

Factors of 180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

Factors of 198: 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198.

The highest common factor of 126, 180, 198 is 9

The largest possible number of teams that can be formed is 9

Each team has

third-graders = 126 / 9

= 14

Fourth-graders = 180 / 9

= 20

Fifth-graders = 198 divided by 9

= 22

There are 9 teams possible each having 14 third-graders, 20 Fourth-graders, 22 Fifth-graders
