Answer:

C

Step-by-step explanation:

If a class has 14 out of 30 students are boys, it has 30 - 14 = 16 girls

ratio of the number of <em>boys</em> to the number of <em>girls</em> means = \frac{Boys}{girls}

Because, firstly it's saying ''<em>boys'' </em>, after <em>''girls''</em>

Boys = 14 girls = 16

14/16 = 7/8

Hope this helps ^-^

7. If U= {2, 4, 6, 8, 10, 12, 14, 16} and<br> A = {6, 10, 14}, what is A'?
Tresset [83]

The compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

We are given the universal set as:

U = {2, 4, 6, 8, 10, 12, 14, 16}

We are also given that set A is:

A = {6, 10, 14}

We need to find A'

For this, we will subtract set A from the universal set, U.

So, we get that:

A' = U - A

A' = {2, 4, 6, 8, 10, 12, 14, 16} - {6, 10, 14}

Solving the expression, we get that:

A' = {2, 4, 8, 12, 16}

Therefore, we get that, the compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.
