Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position
There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C
Multiply those values out: 9*8*7 = 72*7 = 504
There are 504 ways to pick three people from a pool of nine.
Answer: 504
Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer
Answer:
y=2/3+4
Step-by-step explanation:
This equation is in Slope-Intercept form, the most common, therefore, y=-2/-3+4 just needs to apply the - x - = + rule to get, y=2/3+4
Answer:
Step-by-step explanation:
so there is 32 kids....1/2 are blonde, 1/4 have black hair, 1/4 have brown hair
