Ateacher collected data from a class of eighth grade students on whether or not they play a sport and whether or not they are in the school musical. the two-way table below shows the data collected.

which association does the two-way table suggest?
a. none of the associations listed are correct.

b. those who are in the school musical tend not to play a sport.

c. those who are in the school musical tend to play a sport.

d. those who are not in the school musical tend not to play a sport.

B. Those who are in the school musical tend not to play a sport.

Step-by-step explanation:

The relative frequency for a data set n is calculated by dividing each frequency by n

.

We have a table that relates students who are in music school with students who practice a sport.

First, we take the population that is in the music school from the table.

Then, of the students who are in the music school, 5 practice some sport and 12 do not practice any sport

Then we calculate the relative frequencies for those who practice a sport and those who do not practice any sport.

________________________________________________________

Relative frequency   Students that are  in the school musical. n=17.  

-------------------------------------------------- ---------------------------------------------

Sport          No Sport      Total n

  5                  12                   17

_______________________________________________

Relative frequency   Students that are  in the school musical. n=17

-------------------------------------------------- --------------------------------------

  Sport  (fr)           No Sport  (fr)         Total n

  5/17 = 0.29           12/17= 0.71                  17

Most students who are in music school do not practice a sport.

70% of students who are in music school do not practice a sport

Now we calculate the relative frequency of students who are not in music school. Of these students 9 of them practice a sport and 4 of them do not practice any sport.

__________________________________________________________

Relative frequency  Students that are not in the school musical. n=13

-------------------------------------------------- ----------------------------------------------------------

 Sport           No Sport      Total n

  9                       4                 13

__________________________________________________________

_______________________________________________

Relative frequency  Students that are not in the school musical. n=13

-------------------------------------------------- --------------------------------------

 Sport   (fr)              No Sport   (fr)                  Total n

9/13= 0.69                 4/13= 0.21                         13

Note that of students who are not in music school, most of them practice a sport.

Finally you can conclude that  the association does the two-way table suggest is:

B. Those who are in the school musical tend not to play a sport.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
