Answer: 8

Step-by-step explanation:

We can use trigonometry to solve this:

If we call the angle at the top Ф then x is the opposite and 8 is the adjacent

Therefore we use Tan to solve this:

Tan Ф = opposite/adjacent

Tan 45 = X/8

1 = X/8

8 x 1 = X

Therefore X = 8

Five thousand raffle tickets are sold for $5 each. 50 winnings numbers will be chosen, 40 of which will win $100 each and 10 of

Allisa [31]

Answer:

Step-by-step explanation:

Given

there are 50 winning number out of which 40 get $ 100 each and 10 wins $ 1000 .

let x denotes the winning from a randomly selected ticket

$x=100\ with\ Probability\ \frac{40}{5000}$

$x=1000\ with\ Probability\ \frac{10}{5000}$

Expected value is given by

$E(x)=100\times \frac{40}{5000}+1000\times \frac{10}{5000}$

$E(x)=0.8+2=2.8$

and Expected return is given by

$=100\times \frac{40}{5000}+1000\times \frac{10}{5000}-5$

$=2.8-5=$ -2.2$
