777dan777 [17]

Answer:

a) 1680

<em>The number of ways to listen to four CDs from a selection of 8 CDs = 1680</em>

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given data the number of CD' s n = 8

<em>We have to selected '4' CD' s  from total '8' CD's</em>

<em>By using permutations </em>

<em>The number of ways to listen to four CDs from a selection of 8 CDs.</em>

<em>                          =     </em>8_{P_{4} }<em> </em>

<em>  we know that </em>

           n_{P_{r} } = \frac{n!}{(n-r)!}

          8_{P_{4} } = \frac{8!}{(8-4)!} = \frac{8 X 7 X 6 x 5 X 4!}{4!} = 1680

<em>The number of ways to listen to four CDs from a selection of 8 CDs = 1680</em>

The sum of two numbers is 27 and the difference is 19. Find the 2 numbers.
zhuklara [117]

Answer:

the sum of two numbers is 27. their difference is 5. find the number

Step-by-step explanation:

Let x be the first number and y be the second number    ...   so we have

x + y  = 27

x - y  =   5            Adding the equations, we have

2x = 32                Dividing through by 2, we have

x = 16                  And substituting  or x in the first equation, we have

16 + y  = 27         Subtract 16 from both sides  

y = 11
