Solve for x. Enter your answer below as an improper fraction in lowest terms,

ICE Princess25 [194]

Answer:

x = $\frac{83}{36}$

Step-by-step explanation:

Given

x - 2 $\frac{1}{4}$ = $\frac{1}{18}$ ( change mixed number to improper fraction )

x - $\frac{9}{4}$ = $\frac{1}{18}$

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = $\frac{83}{36}$

A raffle has a grand prize of a European cruise valued at $10000 with a second prize of a Rocky Point vacation valued at $700. I

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
