120 students in 5 grade class are surveyed about what kinds of pets they have. of the 120 students, 30 have a goldfish, 40 have a mouse, and 10 have a goldfish and a mouse. using this information, answer each of the following questions. let’s g be event that a randomly selected student has a goldfish and m be the event that a randomly selected student has a mouse.

step-by-step explanation: yes

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

r = 78539458390583095803458309458039485093485 or just 3
