Someone help I think this is probability but I don’t know

ANSWER

1. 3391680

2. 3876

EXPLANATION

1. We want to find the value of:

$P^{12}_7$

This is called "12 permutation 7"

Permutation function is defined as follows:

$P^n_r\text{ = }\frac{n!}{(n-r)!}$

Therefore, we have that:

$\begin{gathered} P^{12}_7=\frac{12!}{(12\text{ - 7)}!}\text{ = }\frac{12!}{5!} \\ P^{12}_7=\frac{12\cdot11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5!}{5!} \\ P^{12}_7=\text{ 12 }\cdot11\cdot10\cdot9\cdot8\cdot7\cdot6 \\ P^{12}_7=3391680 \end{gathered}$

2. We want to find:

$C^{19}_{15}$

This is called "19 combination 15"

Combination function is defined as:

$C^n_r=\frac{n!}{(n-r)!\cdot r!_{}}$

Therefore, we have that:

$\begin{gathered} C^{19}_{15}\text{ = }\frac{19!}{(19-15)!\cdot15!}\text{ = }\frac{19!}{4!\cdot15!} \\ ^{}C^{19}_{15}=\frac{19\cdot18\cdot17\cdot16\cdot15!}{4\cdot3\cdot2\cdot1\cdot15!} \\ C^{19}_{15}=\frac{19\cdot18\cdot17\cdot16}{4\cdot3\cdot2\cdot1} \\ C^{19}_{15}=\text{ 3876} \end{gathered}$

Need help with this will mark brainiest

Harlamova29_29 [7]

Answer:

a) $\boxed{\boxed{\sf p = 18 }}$

b) $\boxed{\boxed{\sf t = 3 }}$

c) $\boxed{\boxed{\sf p = 6 / by /5 }}$

Explanation -

a) 2/3 p + 10 = r

Value of r = 22 (given)

2/3 p + 10 = 22

2/3 p = 22- 10

2/3 p = 12

p = 12 × 3 /2

p = 6 × 3

p=18

b) (-17) + 5k = t

value of k = 4 (given)

(-17) +5 (4) = t

(-17) + 20 = t

3 = t

c) 0 = 5p - 3b

b= 2 (given)

0 = 5p - 3(2)

0 = 5p - 6

6 = 5p

6/5 = p
