In a group of 120 people. each person has a dog, a cat, or a bird. The frequency table shows how many people have each kind of pet. complete a relative frequency table to show the distribution of the data with respect to all 120 people.

25%    19.2%  45.0%

18.3%   16.7%   34.0%

11.7%     8.3%    20.7%

55.8%   44.2%   100%

Step-by-step explanation:

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
