<u>Given</u>:

Given that in a game a player draws and replaces a card from a deck 2 times.

The possible outcomes and payouts are given.

We need to determine the expected value for someone playing the game.

<u>Expected value:</u>

The expected value for someone playing the game can be determined by

EV=(\frac{26}{52})(\$ 20)+(\frac{52}{52})(\$4)+(\frac{52}{52})(\$ 0)+(\frac{26}{52})(-\$12)

Simplifying the values, we have;

EV=(\frac{1}{2})(\$ 20)+(1)(\$4)+(1)(\$ 0)+(\frac{1}{2})(-\$12)

Dividing the terms, we get;

EV=\$ 10+\$4+\$ 0+-\$6

Adding, we have;

EV=\$ 8

Thus, the expected value for someone playing the game is $8

As shown, a section of a roller coaster track (figure 3) follows the form of y=(2/3)x1.5. locate the centroid x? of the track be
LiRa [457]
F(x)=(2/3)x^1.5

The centroid position along the x-axis can be obtained by 
integrating the function * x to get the moment about the y-axis, 
then divide by the area of the graph,
all between x=0 to x=3.5m.

Expressed mathematically,
x_bar=(&int;f(x)*x dx )/(&int; f(x) dx  limits are between x=0 and x=3.5m
=15.278 m^3 / 6.1113 m^2
=2.500 m

What is the value of k?
Romashka-Z-Leto [24]

Answer:

k = 10

Step-by-step explanation:

The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.  

So 10k + 15 must equal the remaining 115

subtract 15 from each side and you get 10k = 100

divide each each by 10 and you get the answer of k = 10
