Tickets numbered 1 - 30.......greater then 20, less then 30 = (21 - 29) = 9 tickets......9/30

tickets numbered 21 - 48...greater then 20 or less then 30 = (21 - 29) = 9 tickets.....9/28

9/30 * 9/28 = 81/840 = 27/280

lisov135 [29]

Answer:

- 3.027

Step-by-step explanation:

First price = 10000 ; second price = 700

Number of tickets sold = 11000

Ticket cost = $4

Probability that a ticket wins grand price = 1 / 11000

Probability that a ticket wins second price = 1 / 11000

X ____ 10000 _____ 700

P(x) ___ 1 / 11000 ___ 1/11000

Expected winning for a ticket buyer :

E(X) = Σx*p(x)

E(X) = (1/11000 * 10000) + (1/11000 * 700) - ticket cost

E(X) = 0.9090909 + 0.0636363 - 4

E(X) = - 3.0272728

E(X) = - 3.027

Answer:

The area of the pentagon is = 31.5

Step-by-step explanation:

<em>First, we determine the perimeter of the "Pentagon" drawn in the attachment:</em>

p=4+4+4+4.5+4.5=21

<em>Now, we'll check the formula for pentagons:</em>

a=\frac{perimeter x apothem}{2}

<em>we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:</em>

apothem=3

<em>then, we can substitute the values in the formula</em>

a=\frac{21(perimeter) x 3(apothem)}{2} =\frac{63}{2} =31 \frac{1}{2} or 31.5
