A survey asked 40 students If they play 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?

352x^2

Step-by-step explanation:

40/times 1.25x/times 2.20x/times 3.2040*1.25x*2.20x*3.20

(40) 1.25x2.20x3.20

+ -. ln > <

* : / log ≥ ≤

() logx = %

1 Take out the constants.

(40/times 1.25/times 2.20/times 3.20) xx (40*1.25*2.20*3.20) xx

2 Simplify 40/times 1.2540*1.25 to 5050.

(50/times 2.20/times 3.20) xx (50*2.20*3.20) xx

3 Simplify 50/times 2.2050*2.20 to 110110.

(110/times 3.20) xx (110*3.20) xx

4 Simplify 110/times 3.20110*3.20 to 352352.
