. The director of a race needs 10 volunteers. Because 20% of the volunteers in the past have not shown up, the director assigns 12 volunteers. Find the probability that 10 volunteers show up, 12 volunteers show up, and at least 10 volunteers show up. Do you think the director is assigning enough volunteers?​

idk

step-by-step explanation:

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

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

the correct answer is c
