For given functions, f(g(4)) = 2, f(f(8)) = ∛2 and f(g(x)) = ∛ ( x² - 8 ).
Describe a function.A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range and a co-domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
In math, various function types exist. Among the crucial kinds are:
When there is a mapping for a range for each domain between two sets, this is known as an injective function or one to one function.
When more than one element is mapped from domain to range, the function is said to be surjective or to be an onto function.
a polynomial function is a function made by of polynomials
Now,
For functions f(x) = ∛ x and g(x) = x²-8
f(g(x)) = ∛ (x²-8)
f(f(x)) = ∛ ∛ x
g(f(x)) = ( ∛ x ) ² - 8
Therefore,
f(g(4))=∛4²-8= ∛16 - 8
= ∛8 = 2
f(f(8)) = ∛ ∛ 8 = ∛2

Ten members Three juniors and seven seniors from the science club qualify for a national competition, but only five
people per school can attend the event. The coach decides to put the 10 members' names on identical slips of
paper, put the slips in a hat, and pull out five names, one at a time. Those five students will go to the national
competition. Let X represent the number of juniors selected to attend the competition.
Have the conditions for a binomial setting been met for this scenario?
Yes, all four conditions in BINS have been met.
O No, we do not know how many people overall will go to the national competition.
No, there is no way to find out the probability of choosing just one student to attend.
No, the names were pulled and not replaced in the hat, so the independence condition is not met.
No, the independence condition is not met. The conditions for a binomial setting have not been met in this scenario because the names were pulled and not replaced in the hat, which violates the independence condition.
In a binomial setting, the trials must be independent, meaning that the outcome of one trial does not affect the outcome of any other trial.
Since the names were not replaced in the hat, the outcome of each draw is not independent, and the conditions for a binomial setting have not been met.

The letter represented by the star symbol is 1.
We can start by using the rules of arithmetic. Since each symbol represents a different digit, we can represent the symbols with the numbers 0 to 9. Then we can write the equation as an algebraic expression and solve for the star symbol.
Let's assign the value of the letter represented by the star symbol to x.
A + B = 10x + x = 11x
We know that the maximum value for the result of the addition (C) is 18 (9 + 9) and that the maximum value for 11x is 990 (90 * 11), so x cannot be greater than 9.
Let's try the lowest value for x, which is 0.
A + B = 10 * 0 + 0 = 0
Since 0 cannot be a digit in A or B, x cannot be 0.
Let's try the next value for x, which is 1.
A + B = 10 * 1 + 1 = 11
Since 11 is a valid result of the addition, x = 1 is a solution.

The value of x in the triangle is given by x = 33.7°
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of hypotenuse = AC = 18 cm
The measure of the opposite side = AB = 10 cm
From the trigonometric relations ,
sin θ = opposite / hypotenuse
Substituting the values in the equation , we get
sin x = 10 / 18
On simplifying the equation , we get
sin x = 0.555556
Taking inverse on both sides of the equation , we get
x = sin⁻¹ ( 0.555556 )
On further simplification , we get

What do you mean by equation?Equation can be used to represent relationships between variables and to solve problems. They are written using an equal sign (=) and can include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.
To make y the subject of the equation x = √((y-1)/(y+1)),
x = √[(y-1)/(y+1)]
we can square both sides:
x² = (y-1)/(y+1)
Next, we can multiply both sides by (y+1) to get rid of the fraction:
x² × (y+1) = y-1
x²y + x² = y - 1
Rearranging the terms:
x² + 1 = y - x²y
x² + 1 = y(1 - x²)
Divide both side by (1-x²) we get
y = (x²+1)/(1-x²)

At a little-known vacation spot, taxi fares are a bargain. A 14-mile taxi ride takes 16 minutes and costs $11.20. You want to find the cost of a 33-minute taxi ride
Answer:
Step-by-step explanation:
To find the cost of a 33-minute taxi ride, we first need to determine the cost per minute of the taxi ride. We can do this by dividing the cost of a 14-mile taxi ride ($11.20) by the time it took (16 minutes):
$11.20 ÷ 16 minutes = $0.70 per minute
Now that we know the cost per minute, we can find the cost of a 33-minute taxi ride by multiplying the cost per minute by 33:
$0.70 x 33 minutes = $23.10
So a 33-minute taxi ride at this vacation spot would cost $23.10.

Solution
This is a normal distribution problem with
Mean = μ =
Standard deviation = o = .
A) Probability that a randomly selected medical
student who took the test had a total score that
was less than 484 = P(x < 484)
We first normalize or standardize 484
The standardized score for any value is the value
minus the mean then divided by the standard
deviation.
z = (x-μ)/o = (484 - 500)/10.4 = - 1.54
To determine the required probability
P(x < 484) = P(z < -1.54)
We'll use data from the normal distribution table
for these probabilities
P(x < 484) = P(z < -1.54) = 0.06178
B) Probability that a randomly selected study
participant's response was between 504 and 516
= P(504 ≤ x ≤ 516)
We normalize or standardize 504 and 516
For 504
z = (x -μ)/σ = (504 500)/10.4 = 0.38
For 516
z = (x - μ)/σ = (516-500)/10.4 = 1.54
To determine the required probability
P(504 ≤ x ≤ 516) = P(0.38 ≤ Z ≤ 1.54)
We'll use data from the normal distribution table
for these probabilities
P(504 ≤ x ≤ 516) = P(0.38 ≤ Z ≤1.54)
= P(z ≤ 1.54) - P(z ≤ 0.38)
= 0.93822 - 0.64803
= 0.29019
C) Probability that a randomly selected study
participant's response was more than 528 = P(x >
528)
We first normalize or standardize 528
z = (x - μ)/σ = (528 - 500)/10.4 = 2.69
To determine the required probability
P(x > 528) = P(z > 2.69)
We'll use data from the normal distribution table
for these probabilities
PP(x > 528) = P(z > 2.69) = 1 - P(z ≤ 2.69)

The complete question is as follows -
In a recent year, the total scores for a certain standardized test were normally distributed, with a mean of 500 and a standard deviation of 10.4.
A) Find the probability that a randomly selected medical student who took the test had a total score that was less than 484. The probability that a randomly selected medical student who took the test had a total score that was less than 484 is:_______.
B) Find the probability that a randomly selected study participant's response was between 4 and 6 The probability that a randomly selected study participant's response was between 4 and 6 is:_______.
C) Find the probability that a randomly selected study participant's response was more than 8. The probability that a randomly selected study participant's response was more than 8 is:________.
The probability that a randomly selected medical student who took the test had a total score that was less than 480 is 0.49, which means that approximately 49% of medical students had a score lower than 480.
To calculate the probability that a randomly selected medical student who took the test had a total score that was less than 480, we need to start by looking at the data given. In this case, the data tells us that the mean score was 500 and the standard deviation was 50. This means that the scores are normally distributed, which means that the probability of finding a score lower than 480 can be calculated using the normal distribution formula. We can use this formula to calculate the area under the curve (or probability) below the score of 480. The result of this calculation is 0.49, which means that approximately 49% of medical students had a score lower than 480.

when using the general multiplication rule, p(a and b) is equal to
The General Multiplication Rule in probability states that the probability of the intersection (occurrence) of two events, A and B, is equal to the product of their individual probabilities. The formula can be written as follows:
p(A and B) = p(A) * p(B | A)
where p(A) represents the probability of event A occurring, and p(B | A) represents the probability of event B occurring given that event A has already occurred.
The formula reflects the idea that the probability of both events occurring is equal to the probability of one event occurring, multiplied by the probability of the other event occurring given that the first event has already happened.
For example, let's say we have two events: "rolling a 6 on a dice" (A) and "choosing a spade from a deck of cards" (B). The probability of rolling a 6 on a dice is 1/6, and the probability of choosing a spade given that a 6 was rolled is 13/52. Using the general multiplication rule, the probability of both events occurring would be (1/6) * (13/52) = 13/312.
In summary, the general multiplication rule is a fundamental concept in probability that helps us calculate the probability of the intersection of two events.

for which numbers c is this matrix not invertible, and why not
The identity matrix of C is invertible, when its determinant is zero.
A matrix is a collection of numbers arranged in rows and columns. In linear algebra, we often work with square matrices, which are matrices with the same number of rows and columns.
Here we have given that for which numbers c is this matrix not invertible.
Here we have to consider that an important property of a square matrix is its invertibility, which determines whether or not the matrix can be "reversed" to get back to the identity matrix.
Therefore, the number "c" for which the matrix is not invertible is when the determinant of the matrix is zero. In other words, the matrix is singular and has no inverse. This can occur when the rows of the matrix are linearly dependent, meaning that one row can be written as a linear combination of the other rows. When this happens, the matrix collapses to a lower-dimensional space, and its determinant becomes zero.
In conclusion, a matrix is not invertible when its determinant is zero, and this is because the matrix has linearly dependent rows and collapses to a lower-dimensional space.

the conical tank shown here is filled with olive oil weighing 41 lb/ft3. how much work does it take to pump all of the oil to the rim of the tank?
The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil multiplied by height of the tank.
Work = 41 lb/ft3 x (height of the tank)
For example, if the height of the tank is 6 ft,
Work = 41 lb/ft3 x 6 ft = 246 lb-ft
The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil multiplied by the height of the tank.
The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil (which is typically measured in pounds per cubic foot) multiplied by the height of the tank in feet. Thus, the work required can be expressed as: Work = (Weight of olive oil) x (Height of tank in feet). For example, if the olive oil has a weight of 41 pounds per cubic foot and the height of the tank is 6 feet, the work required to pump the olive oil to the rim of the tank would be 246 lb-ft (41 lb/ft3 x 6 ft).

The answer inequality of the given line will be -4<n<5.
What is number line?A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0).
These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.
The endpoints of the given line are -4 and +5.
So the value of inequality should lie between these two lines only.
The inequality can be written as n< 5 and n>-4
or -4<n<5
Hence the answer inequality of the given line will be -4<n<5.

The area of the right triangle shown is 24 square feet.
Which equations can be used to find the lengths of the legs of the triangle? Select three options.
0.5(x)(x + 2) = 24
x(x + 2) = 24
x2 + 2x – 24 = 0
x2 + 2x – 48 = 0
x2 + (x + 2)2 = 100
The equation for the length of the legs is:
0.5*(x + 2)*x = 24
Which equation can be used to find the area?Remember that the area of a right triangle is equal to the product between the lengths of the legs over 2.
Then, if here the area is 24ft.
And the legs measure x and (x + 2), then the area equation will be:
x*(x + 2)/2 = 24
We can rewrite the 1/2 as 0.5, so we will get.
0.5*(x + 2)*x = 24
That is the equation on the first option.
