The correct statement is that g(x) is a function because f(x) is one-to-one.

What is an inverse function?

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

We know a function f(x) has its inverse g(x) if and only if f(x) is a one-to-one function.

From the given statements the only true statement is, g(x) is a function because f(x) is one-to-one.

At the start of a soccer game, the referee flips a coin to determine which team gets the ball first. The referee making
the calls for your upcoming game has seen the last 5 coin flips come up tails. The team captain plans to call heads
during the coin flip because he says it is long overdue.
Is your friend's reasoning correct?
O Yes, the coin flip is more likely to come up heads in order for the probability of heads to get back to 0.5.
No, it is highly unlikely to get 5 tails in a row by chance alone, so the friend should continue to go with tails. This
referee must be using an unfair coin.
O No, the probability of getting heads or tails is 0.5, regardless of the outcomes of the previous flips.
Yes, after so many tails in a row, the coin is due to show heads.

Here are recipes for two mixtures of salt and water that taste different. Mixture A: salt (teaspoons) water (cups) 4 5 7 8 3/4 9 11 1/4 Mixture B is defined by the equation y=2.5x , where x is the number of teaspoons of salt and y is the number of cups of water. Respond to the following questions: 1. If you used 10 cups of water, which mixture would use more salt? How much more? Explain or show your reasoning. 2. Which mixture tastes saltier? Explain how you know.

Answers

Answer:

1.) Mixture A will use more salt.

Mixture A will require 4 more spoons of salt than mixture B of 10 cups of water is used.

2.) Mixture A

Step-by-step explanation:

Given the daya:

MIXTURE A

___Salt A(teaspoons _____water (Cups)

___4 _____________5

___7 _____________8 3/4

___9 _____________ 11 1/4

Mixture B is defined by the equation'

y = 2.5x ;

x = number of teaspoons of salt ;

y = number of cups of water

Respond to the following questions:

1.) If you used 10 cups of water, which mixture would use more salt? How much more? Explain or show your reasoning.

For mixture B:

If number of cups of water, y = 10

y = 2.5x ; 10 = 2.5x

10/2.5 = x

x = 4 ; 4 teaspoons of salt

Let's write an equation in terms of y and x to represent mixture A.

Mixture A:

5 = k4

k = 5/4

k = 1.25

Equation for mixture A:

y = 1.25x

10 = 1.25x

10/1.25 = x

x = 8 ; 8 teaspoons of salt

Mixture A will use more salt.

Mixture A will require 4 more spoons of salt than mixture B of 10 cups of water is used.

2. Which mixture tastes saltier? Explain how you know.

Mixture A is saltier as it makes use of more teaspoons of salt for the same amount of water.

1. Mixture A will use 4 more teaspoon of salt

2. The mixture that makes use of more teaspoon of salt (4 teaspoon) for the same quantity of water (10 cups) will taste saltier, which is: Mixture A.

Recall:

A proportionate relation is defined by the formula: y = kxk is the constant of proportionality or unit rate between two variables.

From the information given:

x = quantity of salt (teaspoons)y = quantity of water (cups)

Therefore, k = y/x

Equation for mixture B is given as: y = 2.5x

Using a pair of values from the table for mixture A, let's find the constant of proportionality and the equation that defines Mixture A.

Using (4, 5):

k = y/4 = 5/4 = 1.25

Thus, substitute k = 1.25 into y = kx

Equation for Mixture A is: y = 1.25x

1. Let's find the mixture that will have more salt if y = 10 (cups of water).

Substitute y = 10 in each equation that defines each mixtures

Mixture A: y = 1.25x

10 = 1.25x

Divide both sides by 1.25

8 = x

x = 8

Amount of salt you will have in mixture A is you use 10 cups of water is 8 teaspoons

Mixture B: y = 2.5x

10 = 2.5x

Divide both sides by 2.5

4 = x

x = 4

Amount of salt you will have in mixture A is you use 10 cups of water is 4 teaspoons

Thus, Mixture A will use 4 more teaspoon of salt.

2. The mixture that makes use of more teaspoon of salt (4 teaspoon) for the same quantity of water (10 cups) will taste saltier, which is: Mixture A.

Permutation represents each of the several possible ways in which a set or number of things can be ordered or arranged.

Given is a bride who is choosing a dress for her bridesmaids which are available in 4 styles, 7 colors, and 5 fabrics.

Now, for every possible style there exist a dress for that color. So, with 4 styles and 7 colors, the total number of possible dresses will be = 7 x 4 = 28. Now, for these 28 dresses, their are 5 different fabric available, so the total number of possible ways or dresses from which she can select the dress are = 28 x 5 = 140

Consider the problem of utility over territory. Lets start simplywith a one-dimensional representation. Consider two actors, 1and 2, with utility functions defined over a single-dimensionalissue space X = [0, 1], but where the actors can own sections orprovinces of the interval. The boundaries between sections aredefined by a vector B = (b1, b2, b3, . . . , bn, 1). Thus, there are n+ 1 provinces. Define a size vector containing the lengths ofeach province, S = (b1, b2 b1, b3 b2, . . . , 1 bn). Define foreach actor an ownership vector Oi with 1s in the place of theprovinces that it owns and 0s elsewhere.1. Assume that each actors utility function is a simple sum ofhow much of the space they own so ui=n+1,j=1, oj,sj(a) Can the players both be made better off by exchangingexisting provinces?(b) Can the players both be made better off by altering theboundaries of the existing provinces while preserving theownership structure?(c) Can the players both be made better off by reducing thenumber of provinces for instance, by consolidatingcontiguous provinces that are owned by the same actor?2. Now assume that the utility function is a function of the sumof the squares of the provinces owned, indicating that there areincreasing returns to the size of a province ui=n+1,j=1, (oj,sj)^2(a) Can the players both be made better off by exchangingexisting provinces (without doing anything else)?(b) Can the players both be made better off by reducing thenumber of provinces for instance, by consolidatingcontiguous provinces that are owned by the same actor?(c) If the actors are free to adjust both the number ofprovinces and the ownership structure, what set ofboundaries is Pareto optimal with this utility function?2.2 (see formula in the attachments) Consider two states, state 1 and state 2, which can unilaterallyset their tariff rates on imported goods, ti 0. Each state has anideal level for its own tariff, and prefers that the othersides tariff be 0, Assume that each sides utility declineswith the distance between the tariff levels and their ideal point,as follows1.
