Answers
A choice rule is rationalizable by a rational preference relation if and only if it satisfies Arrow's axiom, which states that if a choice rule selects a set A from a set of alternatives and there is a subset A' of A such that the choice rule also selects A' when presented separately, then the choice rule should select the intersection of A and A'.
Arrow's axiom is a fundamental property of choice rules, and it serves as a condition for rationality in decision-making. A choice rule that satisfies Arrow's axiom ensures consistency in decision-making by treating subsets of selected alternatives consistently.
If a choice rule is rationalizable by a rational preference relation, it means that the choice rule can be explained or represented by a preference relation that follows the principles of rationality. Rational preferences adhere to transitivity, completeness, and continuity.
Arrow's axiom guarantees that a choice rule is consistent with rational preferences. If a choice rule satisfies Arrow's axiom, it implies that the preference relation that rationalizes the choice rule is also consistent with transitivity, completeness, and continuity. Conversely, if a choice rule is rationalizable by a rational preference relation, it must satisfy Arrow's axiom to maintain consistency with rational decision-making.
In conclusion, a choice rule is rationalizable by a rational preference relation if and only if it satisfies Arrow's axiom. This demonstrates the relationship between rational preference relations and the consistency condition set by Arrow's axiom in decision-making processes.

if 19 fish are randomly selected, what is the probability that the mean weight will be between 16.1 and 20.6 lb?
Answers
To find the probability that the mean weight of 19 fish is between 16.1 and 20.6 lb, you would need to know the distribution of the weights of the individual fish. If the weights of the fish are normally distributed with a mean of 18.4 lb and a standard deviation of 2.5 lb, then you can use a normal distribution to find the probability that the mean weight of the 19 fish falls in the specified range.
How does probability work exactly?
Probability is calculated by dividing the total possible outcomes by the number of outcomes that are theoretically possible. Probability differs from odds in this regard. Calculating odds involves dividing the likelihood of a particular event by the likelihood that it won't occur.

Answers
The volume of the rectangular building is 2,731,050 feet³ depending on the given height, base and width.
The volume of the building will be calculated by the formula -
Volume = length × breadth × height

where g(x) is the translation 1 unit down of f(x)=x2.
Answers
The required equation of function g(x) is x²- 1.
To find the function g(x), which is the translation 1 unit down of f(x) = x², we can subtract 1 from the y-coordinate of each point on the graph of f(x).
The graph of f(x) = x² is a parabola that opens upward and passes through the origin (0, 0). The y-coordinate of any point on this parabola is equal to the square of its x-coordinate.
The function g(x) can be written as:
g(x) = f(x) - 1
= x² - 1

https://brainly.com/question/12463306
#SPJ1
After the translation 1 unit down of the function f(x)=x² is g(x) = x² - 1.
The given function is f(x)=x².
The translation of a function f(x) 1 unit down is given by g(x) = f(x) - 1.
So, for f(x) = x², the translation 1 unit down of f(x) is g(x) = x² - 1.
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Horizontal Shift: None
Vertical Shift: Down 1 Units
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: None
Therefore, after the translation 1 unit down of the function f(x)=x² is g(x) = x² - 1.

Ralph deposited $910 in an account that pays 5.2% simple interest, for 3 1/2years.
a. How much interest did the account earn?
Answers
Answer:
$1075.62
Step-by-step explanation:
Given data
Principal=$910
Rate= 5.2%
Time=3 1/2 years = 3.5 years
The simple interest expression is given as
A=P(1+rt)
Substitute
A=910(1+0.052*3.5)
A=910(1+0.182)
A=910*1.182
A=$1075.62
Hence the account balance will be $1075.62
a ladder 26 feet long is leaning against the wall of a house (see the figure below). the base of the ladder is pulled away from the wall at a rate of 3 feet per second. how fast is the top of the ladder moving down the wall when its base is 10 feet from the wall?
Answers
The rate at which the top of the ladder is moving down the wall = 9 feet/second.
This is a problem of right triangle similarity.
We can use the Pythagorean theorem to find the height of the ladder, which is the hypotenuse of a right triangle.
We can use the relationship between similar triangles to find the rate at which the top of the ladder is moving down the wall.
Let x be the distance of the base of the ladder from the wall.
We know that the ladder is 26 feet long, so the height of the ladder is the square root of (26^2 - x^2).
We know that the base of the ladder is moving away from the wall at a rate of 3 feet per second.
So, the rate at which the top of the ladder is moving down the wall is (3 feet/second) * (height of ladder / x)
When x = 10 feet, the height of the ladder is the square root of (26^2 - 10^2) = the square root of (676) = 26 feet.
So, the rate at which the top of the ladder is moving down the wall is (3 feet/second) * (26 feet / 10 feet) = 9 feet/second.

Assuming that all four of the following functions are defined, which one will be called by the function call square( 23.4 )?
Answers
The specific function that will be called by the function call square(23.4) cannot be determined without knowing the definitions of the four functions.
The answer depends on the function signatures and parameter types of the defined functions.
To determine which function will be called, we need to consider the parameter types and function signatures of the four defined functions. If one of the functions has a parameter that matches the type of the argument passed (in this case, 23.4), that function will be called.
The function definition must explicitly state a parameter of the appropriate type to match the argument. Without knowledge of the function definitions and their parameter types, it is not possible to determine which specific function will be called by the function call square(23.4).

find the gradient of a line that is perpendicular to 8y+4x=5
Answers
Answer:
gradient = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
8y + 4x = 5 ( subtract 4x from both sides )
8y = - 4x + 5 ( divide the terms by 8 )
y = - \(\frac{1}{2}\) x + \(\frac{5}{8}\) ← in slope- intercept form
with gradient = - \(\frac{1}{2}\)
Given a line with gradient m then the gradient of a line perpendicular to it is
\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{2} }\) = 2
2 is the gradient of a line that is perpendicular to 8y+4x=5
What is slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane
The slope of line can also be called ad gradient of a line.
The standard form of line or slope intercept form of a line is given by
y=mx+c
where m is the slope of line and c is the y intercept.
The given equation of line is 8y+4x=5
We need to convert the equation of line to Slope intercept form
8y=5-4x
Divide both sides by 8
y=5/8-4/8x
y=-1/2x+5/8
So m is -1/2.
Two lines are said to be perpendicular if m₁m₂ =-1
if m₁=-1/2
then we need to calculate m₂
-1/2m₂=-1
m₂=2
Hence gradient of a line that is perpendicular to 8y+4x=5 is 2.

Six teachers and 12 students volunteer for a committee to discuss extra-curricular activities. How many committees of 5 people can be made if:
a) there must be exactly 3 students on the committee
b) there must be at least one teacher and at least one student on the committee
Answers
Answer:
a) 11,880
b) 7,770
Step-by-step explanation:
The number of teachers that volunteer = 6 teachers
The number of students that volunteer = 12 students
The number of people in the committee = 5 people
a) The exact number of student on the committee = 3 student
Therefore, the number of teachers in the committee of 5 = 5 - 3 = 2
The number of teachers in the committee = 2 teachers
We get;
The number of committees that can be made = ₁₂C₃ × ₆C₂ = 792×15 = 11,880
b) When there is at least one teacher and at least one student on the committee, we have;
₁₂C₄ × ₆C₁ + ₁₂C₃ × ₆C₂ + ₁₂C₂ × ₆C₃ + ₁₂C₁ × ₆C₄ = 7,770
The number of committees having at least one teacher and at least one student = 7,770
