How do you find the equation of the midline for a function?
Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .
What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equality of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to express the connection between two phrases on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
Here,
The midline equation is y = M+m /2
when a function has: o a max M AND a min m or o (if it does not have extrema) a bound above M and a bound below m, where M is the minimum bound above and m is the maximum bound below.
When one of the following conditions is true for a function, even though it has a bound below, there is no midline (even if it has a bound above)
It is solely constrained from above (or below)
Any line is midline if a function has the values (-∞, +∞)
Therefore , the solution to the given problem is the equation of the midline is: y = M+m /2 .

The ultimatum game is a popular research tool for studying topics such as fairness and altruism. The game itself is simple. Two players are told that they will be dividing up a sum of money. One player is designated as the proposer. Her job is to suggest a division of the sum. The second player is designated the responder, and he decides to either accept the proposed division (in which case the division stands and each player is paid accordingly) or to reject the proposed division, in which case both players get nothing.
Part 1 (1 point) See Hint Consider an implementation of the ultimatum game in which the players divide up a pot of $60. To keep the analysis easier, you can assume that all divisions must occur in $1 increments. What is the rational, game-theoretic solution to this game?
A. The proposer suggests a 50/50 division (so each player would get $30), and the responder rejects.
B. The proposer suggests an uneven split favorable to herself (so the proposer would get $36, and the responder would get $24), and the responder accepts.
C. The proposer suggests an uneven split favorable to the other player (so the proposer would get $24, and the responder would get $36), and the responder accepts.
D. The proposer suggests close to an all/nothing split favorable to the other player (so the proposer would get $1, and the responder would get $59), and the responder rejects.
E. The proposer suggests an uneven split favorable to the other player (so the proposer would get $24, and the responder would get $36), and the responder rejects.
F. The proposer suggests close to an all/nothing split favorable to the other player (so the proposer would get $1, and the responder would get $59), and the responder accepts.
G. The proposer suggests an uneven split favorable to herself (so the proposer would get $36, and the responder would get $24), and the responder rejects.
H. The proposer suggests a 50/50 division (so each player would get $30), and the responder accepts.
I. The proposer suggests close to an all/nothing split favorable to herself (so the proposer would get $59, and the responder would get $1), and the responder accepts.
J. The proposer suggests close to an all/nothing split favorable to herself (so the proposer would get $59, and the responder would get $1), and the responder rejects.
Part 2 (1 point) See Hint When this game is played with real people, does the result typically match the game-theory prediction discussed in Part 1? yes no
Answer:
1. The rational, game-theoretic solution to this game is:
H. The proposer suggests a 50/50 division (so each player would get $30), and the responder accepts.
2. No. When this game is played with real people, the result does not typically match the game-theory prediction discussed in Part 1.
Step-by-step explanation:
Players in a game respond with different strategies, which are usually unknown to the second player. While people are expected to act rationally, most times, they do not. They are propelled by different rationality and preferences. Therefore, players' game strategies are unpredictable.

310
260
200
If the probability of s1 = .6 the value above node degree 4 will be 320, as determined by the solution.
What does a node's degree mean?The area of mathematics known as probability deals with numerical descriptions about how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
According to the given information:S1 probability = 0.6
F's likelihood is 0.40.
If the probability of S1 is given a value of 0.6, then
Probability of S2 then equals 0.4.
Using the table equation's payoff values as an exception.
EV=Σ
Each decision's expected value is calculated.
EV(Node 8) = 0.6 * 100 + 0.4 * 300
= 180
EV(Node 9) = 0.6 * 400 + 0.4 * 200= 320
We chose the best value for node 4 from nodes 8 and 9.
The ideal option for node 9 is the line complicated branch with EV(node 8) = 180.
The ideal anticipated value is determined to be 320.
Node 4's EV is 320.

Answer: 3.75 ft
Step-by-step explanation:

So since area is A= L*W
8*3.75=30 ft2
2) Which of the following would be A' if A (2, -3)
was reflected over the x axis?
a. A'(-2, -3)
c. A'(-2, 3)
b. A'(2, 3)
d. A'(2, -3)
A'(-2, -3) would result if A (2, -3) was reflected over the x axis. Point (2,3)'s representation under the x-axis is (2,-3). from the y-axis P image (-a,b).
What is (2, -3) reflected over the x-axis?Changing the sign of the value on the opposite axis, in this case the y-value, is all that is required to reflect a point such as (-2,3) across the x-axis in a question. As a result, this location has a y-value of 3. A positive number, this. A negative sign produces a result of -3.
While the Y coordinate remains the same when you reflect across the Y-axis, the X coordinate changes sign. Determining the reflection of (2, 3) across the Y-axis is therefore (-2, 3). The Y-coordinate of each point must be negative while reflecting across the X axis, but the X value must remain constant.
Therefore the correct answer is option a ) A'(-2, -3)

Answer:
[tex]\implies \boxed{\red{\sf ( x +1)^2 = \dfrac{1}{4}}} [/tex]
Step-by-step explanation:
Given :-
A equation is given to usThe equation is 4x² + 8x + 3 = 0And we need to write the equation by completing the square. Here's the step by step explanation .
Step 1: Make the coefficient of x² as 1 :-
[tex]\implies \dfrac{4x^2}{4} + \dfrac{8x}{4} + \dfrac{3 }{4}= 0 [/tex]
Step 2: Rewrite the equation :-

Step 3: Add 1² to both sides :-
[tex]\implies x^2 + 2x + 1^2+\dfrac{3}{4}= 0 + 1^2 [/tex]
Step 4: Rewriting in whole square form:-
[tex]\implies ( x +1)^2 = 1 - \dfrac{3}{4} [/tex]
Step 5: Simplify the RHS :-
[tex]\implies ( x +1)^2 = \dfrac{4- 3}{4} [/tex]
Step 6: The required form of equⁿ :-

A manufacturer produces soda cans and a quality control worker randomly selects two cans from the assembly line for testing. Past statistics show that 10% of the cans are defective. What is the probability that the two selected cans are defective if the quality control worker selects the two cans from a batch of 60 cans?
Answer:
It would be 1%
Step-by-step explanation:
First of all, note that any of the cans with the batch have the same chance at being defective, so ingore that. However, note the chance that each one is defective:
10%
So if you picked up any can, it would have a 10% chance of being defective. With this, by picking up two cans, you would do:
0.1 * 0.1 = 0.01
To find the chance of both cans being defective, being 1% for both of the selected cans being defective.

What is a system of linear equations?A system of linear equations is a collection of two or more linear equations that have the same variables. A linear equation is an equation in which the highest power of the variable is 1. In other words, the equation is a straight line when graphed.
Here is an example of a system of linear equations:
3x + 2y = 19
2x + 4y = 18
This is a system of equations problem, where we can use the information provided to set up two equations and then solve for the unknown variables. Let x be the cost of one cheeseburger and y be the cost of one cup of lemonade.
From the information provided, we know that:
3x + 2y = 19 (the cost of 3 cheeseburgers and 2 cups of lemonade is $19)
2x + 4y = 18 (the cost of 2 cheeseburgers and 4 cups of lemonade is $18)
To find the cost of one cheeseburger and one cup of lemonade, we can solve this system of equations. One way to do this is by substitution.
3x + 2y = 19
we get
[tex]x=\frac{19-2y}{3}[/tex]
substituting x in equation 2x+4y=18
we get
[tex]2(\frac{19-2y}{3})+4y=18[/tex]
[tex]38 - 4y + 12y = 54\\8y = 16\\y = 2[/tex]
substituting y in equation 3x+2y=19
[tex]3x+2(2)=19\\3x=19-4\\3x=15\\x=5[/tex]

question 1: Since it's a parallelogram opposite sides are equal.
4x+5=5x-1 add one to both sides
4x+6 =5x subtract 4x from both sides
6 = x
So AD is equal to 5(6) - 1 = 30-1 = 29=AD
Question 2: Since diagonals in a parallelogram bisect each other AE = EC
So...
5x+5 = 8x- 7 add 7 to both sides
5x+12 = 8x subtract 5x from both sides
12=3x divide both sides by 3
4=x
AC= 5(4) + 5 + 8(4) - 7
