Sylvia surveyed her classmates at school to find out who plays sports at her school.the table below shows the number of students

Neporo4naja [7]

Answer:

Using the info you just gave,

Basketball, 8 studentsfootball, 7 studentsSoccer 12 studentsother, 13 students

We can now figure out the percentage of students that did NOT select soccer.

First, you need to add all the students together.

8 + 7 + 12 + 13

You get 40 students all together.

Now, add together the students that DID NOT choose soccer.

7 + 8 + 13 = 29

That means that 28/40 of the students did not choose soccer.

Now, convert that to a percentage.

28/40 = 0.7

To make that into a percentage, multiply by 100

Thus, the percentage of students that did not select soccer is 70%.

Hope this helped!

Students were surveyed about their preference between dogs and cats. The following two-way table displays data for the sample of

lesya [120]

Based on the data presented, it can be concluded out of the 52 females 26 prefer cats.

<h3>How to read the graph?</h3>

To read the graph we must take into account that the rows refer to the preference of men, preference of women and those who have no preference.

On the other hand, the columns refer to the number of students of both genders who prefer or do not prefer each animal. Additionally, adding all the students of each gender we have the total of the sample.

According to the above, the total sample of female students would be 52.

20 + 26 + 6 = 52

According to the above, the fraction that expresses this relationship correctly is:

$\frac{26}{52}$

Note: This question is incomplete because the graph is missing. Here is the graph.
