Someone help I think this is probability but I don’t know
pickupchik [31]

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}

Hamburger Heaven is having a lunch special where customers buy one 1/2- pound cheeseburger and gets one free. If they set aside
ale4655 [162]

 

We are given that in one cheese burger, the amount of meat that it contains is a half pound, so:

meat in a cheese burger = 0.5 pound /cheese burger                                      ---> 1

 

We are also given that the total pounds of meat available for making the cheese burger is:

total meat available = 50 2 / 3 pounds

if expressed in decimal form is also equivalent to:

total meat available = 152 / 3 pounds = 50.67 pounds                                      ---> 2

 

Therefore to get the amount of burgers that can be make, we divide 2 by 1 to get units in cheese burger:

number of cheese burger = 50.67 pounds / (0.5 pound /cheese burger)

number of cheese burger = 101.33

 

Therefore about 101 cheese burgers can be made.
