How many ways can a committee of five be chosen from 120 employees to interview prospective applicants.

REY [17]

Answer:

190578024 ways.

Step-by-step explanation:

We are asked to find the number of ways in which a committee of 5 be chosen from 120 employees to interview prospective applicants.

We will use combinations to solve our given problem.

$_{r}^{n}\textrm{C}=\frac{n!}{(n-r)!r!}$ , where,

n = Total number of items,

r = Number of items being chosen at a time.

Upon substituting our given values in above formula, we will get:

$_{5}^{120}\textrm{C}=\frac{120!}{(120-5)!5!}$

$_{5}^{120}\textrm{C}=\frac{120!}{115!*5!}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116*115!}{115!*5*4*3*2*1}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116}{5*4*3*2*1}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116}{120*1}$

$_{5}^{120}\textrm{C}=\frac{119*118*117*116}{1}$

$_{5}^{120}\textrm{C}=\frac{190578024}{1}$

Therefore, the committee of five can be chosen from 120 employees in 190578024 ways.

Which is true about the volume or surface area of these prisms?

GrogVix [38]

The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...

Figure A's Volume= 60

Figure B's Volume= 60

Figure A's Surface Area= 104

Figure B's Surface Area= 248

So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.

Hope that helps. :)
