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
That would be a total of 9 half meters

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>

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

<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>
