Answer:

Step-by-step explanation:

Given that St. Mary's Church is holding a raffle in which 1172 tickets have been sold at a cost of $2.00 each.

Three prizes will be awarded: 1 for S500;1 for $250; 1 for $125.

Thus total number of tickets = 1172

Of these prize winning are 3

i.e. Tickets        Prize $     Net win amount            Prob       Net win amt*prob

         1                 500                (500-2) =448          1/1172           448/1172

         1                250                 (250-2) =248          1/1172           248/1172

          1               125                   (125-2) =123            1/1172          123/1172

       1169               0                    (0-2) =    -2             1169/1172    -2338/1172

Expected value = Total                                                                 -1519/1172

=-1.296

The digits of a two-digit number sum to 8. When the digits are reversed, the resulting number is 18 less than the original numbe
Oksanka [162]

Answer:

original number = 53

Step-by-step explanation:

In two digits number:

Let the tens place digit be x and units place digit be y.

So,

Original number = 10x + y

Number obtained after reversing the digits = 10y + x

According to the first condition:

x + y = 8.... (1)

According to the second condition:

10y + x = 10x + y - 18

10y + x - 10x - y = - 18

9y - 9x = - 18

-9(x - y) = - 18

x - y = - 18/(-9)

x - y = 2.......(2)

Adding equations (1) & (2), we find

x + y + x - y = 8 + 2

2x = 10

x = 10/2

x = 5

Plug x = 5 in equation (1), we find:

5 + y = 8

y = 8 - 5

y = 3

10x + y = 10*5 +3 = 50 + 3 = 53

Hence, original number = 53

Phantasy [73]

Answer:

it cost 80 dollars

Step-by-step explanation:

cost per bag for X brand =25 $

cost per bag for y brand = 20$

minimize Z=(25X +20 y)

further formulate the problem

the given constraints are

2x + y equal 12

2x + 9y equal 36

2x + 3y equal 24

well on the graph given plot of the constraints

the corner points are

(0;0)

(6;0)

(0;4)

(9;2.5)

minimum z occurs at (0:4)

value of Z(minimum cost)=80$
