Asurvey asked 40 students if they plan an instrument and if they are in band. 1. 25 students play an instrument. 2. 20 students are in band. 3. 20 students are not in band which table shows these data correctly entered in a two-way frequency table? apex

Option: C is the correct answer.

The two-way frequency table is given as:

                                         Band            Not in Band       Total

Play instrument                    20                     5                   25

Do not play instrument        0                       15                 15

Total                                     20                      20                40

Step-by-step explanation:

We are given a survey of 40 students regarding whether they play an instrument or not.

We are given an information as:

1. 25 students play an instrument.

2. 20 students are in band.

3. 20 students are not in band

Hence, the table can be formed as:

                                          Band            Not in Band       Total

Play instrument                    20                     5                   25

Do not play instrument        0                       15                 15

Total                                     20                      20                40

( Since, those who don't play any instruments can't even play band hence the value of that in table is 0)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

hi how are you doing today, if you need just ask me.
