</span>
C_{11}^6= \frac{11!}{6!\cdot (11-6)!}= \frac{1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7\cdot8\cdot9\cdot10\cdot11}{1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot1\cdot2\cdot3\cdot4\cdot5}  = \frac{7\cdot8\cdot9\cdot10\cdot11}{2\cdot3\cdot4\cdot5} =462.

Answer: 462 ways to complete the <span>drumline for a football game.</span>

sukhopar [10]

Answer:

242 members voted in favor while 193 members voted against

Step-by-step explanation:

Let those that voted against be x will those in favor will be (x+49)

Since today number of voters is 435

To find x

X + (x+49) = 435

2x + 49 = 435

2x = 435 - 49

2x = 386

X = 386/2

X = 193

Therefore, those against is 193 while this in favor is 193+49 = 242
