Dimas [21]

Answer:

Na = 720 - 120 = 600 ways

The 3 people can arrange themselves in 600 possible ways.

Step-by-step explanation:

For at least one of the three friends to seat on an aisle seat, the number of possible arrangements can be given as;

Na = Nt - Nn .....1

Where;

Na = number of possible arrangements with at least one of the seating on an aisle seat.

Nt = total number of possible arrangements for the three friends

Nn = number of possible arrangements with none of the three friends seating on an aisle seat.

Given;

Total number of seats available = 10

Total number of aisle seats available = 4

Total number of people = 3

So;

Nt = 10C3 = 10×9×8 = 720

Nn = (10-4)C3 = 6C3 = 6×5×4 = 120

From equation 1;

Na = 720 - 120 = 600 ways

The 3 people can arrange themselves in 600 possible ways.

DENIUS [597]

Answer:

She have <u>53</u> type of quarters and <u>27</u> type of nickels.

Step-by-step explanation:

Given:

Sam has a jar contain 80 coins, all of which are either quarters or nickels.

The total value of quarters and nickels is $14.60.

Now, to get each type of coin she have.

Let the number of quarters be $x.$

And let the number of nickels be $y.$

<u><em>So, total number of coins:</em></u>

$x+y=80$

$y=80-x\ \ \ ....(1)$

<u><em>Now, the total value of coins:</em></u>

$0.25(x)+0.05(y)=14.60$

Substituting the value of $y$ from equation (1):

$0.25(x)+0.05(80-x)=14.60$

$0.25x+4-0.05x=14.60$

$0.20x+4=14.60$

<em>Subtracting both sides by 4 we get:</em>

<em /> $0.20x=10.60$ <em />

<em>Dividing both sides by 0.20 we get:</em>

$x=53.$

<u>The number of quarters = 53.</u>

Now, to get the number of nickels by substituting the value of $x$ in equation (1):

$y=80-x\\\\y=80-53\\\\y=27.$

<u>The number of nickels = 27.</u>

Therefore, she have 53 type of quarters and 27 type of nickels.
