For the school play, adult tickets cost 4 and children tickets cost 2. Natalie is working at the ticket counter and just sold 20

Svetradugi [14.3K]

The possible combinations of adult tickets and children tickets are : (0, 10), (1, 8), (2, 6), (3, 4), (4, 2), (5, 0)

<u><em>Explanation</em></u>

Suppose, the number of adult tickets is $x$ and the number of children tickets is $y$

Given that, adult tickets cost 4 and children tickets cost 2 and Natalie sold 20 worth of tickets. So the equation will be.....

$4x+2y=20\\ \\ 2y= 20-4x\\ \\ y= 10-2x$

If x = 0, then $y= 10-2(0)= 10$

If x = 1 , then $y= 10-2(1)= 8$

If x = 2 , then $y= 10-2(2)= 6$

If x = 3 , then $y= 10-2(3)= 4$

If x = 4 , then $y= 10-2(4)= 2$

If x = 5 , then $y= 10-2(5)= 0$

If we take x value greater than 5 , then y will become negative which is not possible.

So, the possible combinations of adult tickets and children tickets are : (0, 10), (1, 8), (2, 6), (3, 4), (4, 2), (5, 0)

Answer:

s inversely proportional 1/t

s=0.3, t=8

s=k/t

0.3=k/8

k=0.3×8

k=2.4

find s when t=0.4

s=2.4/0.4

s=6.0 or 6

A dice game lets you roll 2 6 sided disc and find the sum of the numbers. A 12 wins 100 dollars, 10 or 11 wins 50 dollars, a 2 w

Advocard [28]

Answer:

Step-by-step explanation:

A two 6 sided die is rolled

Sample space would be (1,1)...(1,6)....(6,1)....(6,6)

Let x be the sum obtained

X can take values as 2 or 3 ....12

P(x=12) = P(6,6) =1/36

P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36

P(2) =P(1,1) = 1/36

For other outcomes no payment

Thus we can list this as

Sum 2 3 4 5 6 7 8 9 10 or 11 12

Prob 1/36 5/36 1/36

Gain 3 0 0 0 0 0 0 0 50 100

E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36

E(gain) = total= 353/36

Cost of game = 6

E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6

= 3.806
