Three officers—a president, a treasurer, and a secretary—are to be chosen from among four people: ann, bob, cyd, and dan. suppose that bob is not qualified to be treasurer and cyd’s other commitments make it impossible for her to be secretary. how many ways can the officers be chosen? can the multiplication rule be used to solve this problem?

y=1/4x-4

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

yes   because as the functions are graphed they eventually will intersect unless otherwise
