Answer:

a)125970

b)95040

c)35640

Step-by-step explanation:

a) selecting 12 player from 20 players can be one in $^{20} C_{12}$

$^{20} C_{12}$ = $\frac{20!}{12!X (20-12)!}$

= $\frac{20!}{12!X8!}$

= $125970$

b) since each position has an identity permutations can be used so

Number of ways = $^{12} P_{5}$

= $\frac{12!}{(12-5)!}$

= $\frac{12!}{7!}$

= $95040$

c) coach permutes 4 players for position other than centers in $^{12}P_{4}$ ways and selects center in 3 ways

so, number of ways = $^{12}P_{4}X3$

= $\frac{12!}{8!}X3$

= $35640$

Vas happening?
You break it down
3 ^5 is 3 x 3 x 3 x 3 x 3 = 729
4 ^ 5 is 4 x 4 x 4 x 4 x 4 = 1024
729 times 1024 = 746,496
12 ^ 10 is 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12 x 12 = 6.19174e10
So the answer is incorrect

Answer:

$11,280

Step-by-step explanation:

Plug in 150 as p into the equation to solve for the cost, C:

C = 30 + 75p

C = 30 + 75(150)

C = 30 + 11,250

C = 11,280

= $11,280
