There is a dice game at the casino that costs $3 to play. A player rolls two dice. If the player gets a sum of 2 or 12 he or she gets back $ 28 (wins $25). the person gets a 7he or she gets back $5 (wins $2). If the player rolls anything other than a 2, 12 or 7 he or she gets nothing back (loses $3). Find the expected value for the player?
Answer:
The expected value for the player is -$0.63.
Step-by-step explanation:
The dice game has the following rules:
The game costs $3 to play. A player rolls two dice. If the player gets a sum of 2 or 12 he or she gets back $ 28 (wins $25). If the person gets a 7 he or she gets back $5 (wins $2). If the player rolls anything other than a 2, 12 or 7 he or she gets nothing back (loses $3).The outcomes for a sum of 2 or 12 are: {(1, 1) and (6, 6)}
The probability of a sum of 2 or 12 is: 2/36 = 0.055.
The outcomes for a sum of 7 is: {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2) and (6, 1)}
The probability of a sum of 7 is: 6/36 = 0.167.
The probability of a sum other than 2, 12 or 7 is: 1 - 8/36 = 0.778
The probability distribution is:
Result X P (X)
Sum 2 or 12 $25 0.055
Sum 7 $2 0.167
Others -$3 0.778
Total 1.000
Compute the expected value as follows:
[tex]E(X)=\sum x\cdot P(x)\\\\[/tex]
[tex]=(25\times 0.055)+(2\times 0.167)+(-3\times 0.778)\\\\=1.375+0.334-2.334\\\\=-0.625\\\\\approx -0.63[/tex]
Thus, the expected value for the player is -$0.63.

The area of a 2D form is the amount of space within its perimeter. The area of the field in square kilometres is 45,000.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that the rectangular field is 300meters long and 150 meters wide. Therefore, the area of the field in square kilometres is,
Area = Length x Width
= 300 meter x 150 meter
= 45,000 meter²
Hence, the area of the field in square kilometres is 45,000.

reflect triangle stu across line st which of these is a valid reason why the image u will coincide with j
1 the image u and j are on the same side of st and make the same angle with it at t
2 the image u and j are the same distance along the same ray from t
3 the image of u and j will not coincide after a reflection over st
4 none of the above
Answer:
4. None of the above
Step-by-step explanation:
Reflection is a type of transformation that can be used to change the orientation of a given figure or shape without changing it size and shape.
When triangle STU is reflected across ST, the image U coincides with J because the two are on the opposite side and at the same distance from ST. Therefore, J is like the image of U.

Answer:
Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)
Step-by-step explanation:
First you have to do all the Distributive property which the answer would be:
2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18
Then you have to find the common demoninator which would be 18
After that you have to put them in the correct order since there is two different terms which would be:
2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x
After that you solve the problem which in the end after solving both terms it ends up as..:
10 2/18 - 1 5/18x
and I think that is as simplified as you can go term wise.

Y=1200 x (1+0.3)^t
What is the initial value and what is the rate of growth
Answer:
initial value is 1200, rate of growth is 0.3
Step-by-step explanation:
A(t) = P(1+r)^t
p= initial value
r= rate of growth
A(t)= amount after
t= time
The initial value is 1200 and rate of growth is 0.3.
What is Exponential function?An exponential function is a mathematical function of the following form: f ( x ) = [tex]a^x[/tex] where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e
Given:
Function: Y=1200 x [tex](1+0.3)^t[/tex]
Now, We know using the Amount formula
A(t) = P[tex](1+r)^t[/tex]

To raise money for after-school programs at an elementary school, a group of parents is holding a weekend of games in a community center. They charge $8 per person for entry into the event. The group would like to earn at least $600, after paying for the cost of renting the space, which is $40 an hour. If x represents the number of entry tickets sold and y the hours of space rental, which inequality represents the constraints in the situation? Group of answer choices 8x-40y 600 8x-40y > 600
Answer:
[tex]8x-40y\geq 600[/tex] and [tex]x>0,y>0[/tex]
Step-by-step explanation:
The number of people is [tex]x[/tex] and the number of hours they are present in the space is [tex]y[/tex].
Per person entry cost is $8.
Per hour cost of rent is $40.
They plan to earn a minimum of $600.
Donations by all the people entering the space is [tex]8x[/tex]
Total cost of renting the space is [tex]40y[/tex] which will be subtracted from the total amount of donations.
The inequality that represents the situation is [tex]8x-40y\geq 600[/tex] and [tex]x>0,y>0[/tex].
