As people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not.
What are the values of a and b in the relative frequency table for the survey results? Round answers to the nearest percent.
A survey among freshmen at a certain university received that the number of hours spent studying the week before final exams was normally distributed with mean 25 and standard deviation 7. Round your answers to nearest hundredth. (e.g. 0.345 would be entered as 0.35) (a) Find the 98th percentile of the number of hours studying.
The 98th percentile of the number of hours spent studying the week before final exams is approximately 39.35 hours.
The 98th percentile of the number of hours spent studying the week before final exams, assuming a normal distribution with mean 25 and standard deviation 7, can be calculated using the standard normal distribution table.
To find the z-score corresponding to the 98th percentile, we use the formula:
z = (x - μ) / σ
where x is the value at the 98th percentile, μ is the population mean, and σ is the population standard deviation.
Using a calculator, we find that the z-score corresponding to the 98th percentile is approximately 2.05.
To find the value of x at the 98th percentile, we rearrange the formula as:
x = μ + zσ
Substituting the given values, we get:
x = 25 + 2.05 × 7 ≈ 39.35

A triangle has sided with lengths of 20 miles, 25 miles, and 30 miles. Is it a right triangle ?
Answer:
No
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
For a Triangle to be a Right-Angled Triangle, should follow the Pythagoras Theorem which states that
If a is the larger side and b , c are the lengths of the other two sides
Then \(a^{2} =b^{2} +c^{2}\)
Here a=30 , Then \(a^{2}=30^{2} =900\)
and b=20 , c=25 , Then \(b^{2} +c^{2} =20^{2} +25^{2} =1025\)
Since \(a^{2} \neq b^{2} +c^{2}\)
Then the Triangle is not Right Triangle
which of the following describes (8+9) in the expression below?
Please see the image below(math)
Answer:

Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
AD AH
----- = ---------
AB AH +y
3 9
---- = ------
10 9+y
Using cross products:
3(9+y) = 9*10
27+3y = 90
3y = 90-27
3y =63
y = 63/3
y = 21
Answer:
y = 21
Step-by-step explanation:
According to the Side Splitter Theorem, if a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.
Therefore, according to the Side Splitter Theorem:
\(\boxed{\sf AD : DB = AH : HC}\)
From inspection of the given triangle, the lengths of the line segments are:
AD = 3DB = 7AH = 9HC = yTo find the value of y, substitute the given line segment lengths into the proportion and solve for y:
\(\begin{aligned}\sf AD : DB &=\sf AH : HC\\\\3:7&=9:y\\\\\dfrac{3}{7}&=\dfrac{9}{y}\\\\3 \cdot y&=9 \cdot 7\\\\3y&=63\\\\\dfrac{3y}{3}&=\dfrac{63}{3}\\\\y&=21\end{aligned}\)
Therefore, the value of y is 21.

air is approaching a converging-diverging nozzle with a low velocity at 20and 300 kpa, and it leaves the nozzle at a supersonic velocity. the velocity of air at the throat of the nozzle is
The velocity of air at the throat using the local speed of sound at the given pressure and temperature conditions.
The velocity of air at the throat of the converging-diverging nozzle can be calculated using the principle of continuity and the isentropic flow equation. It is a function of the Mach number, which is constant at the throat, and the local speed of sound.
To calculate the velocity of air at the throat, we need to use the principle of continuity, which states that the mass flow rate of a fluid remains constant as it passes through a converging-diverging nozzle. This means that the mass flow rate at the throat is the same as the mass flow rate at the inlet and outlet of the nozzle.
Using the isentropic flow equation, we can relate the velocity of the air to the Mach number and the local speed of sound. At the throat, the Mach number is equal to 1, which means that the velocity of the air is equal to the local speed of sound. Therefore, we can calculate the velocity of air at the throat using the local speed of sound at the given pressure and temperature conditions.

Give an example of a metric space (X, d) and a non-empty subset A such that every point in A is a limit point of A but int(A) = θ
Metric spaces are mathematical structures that consist of a set and a distance function. An example of a metric space (X, d) and a non-empty subset A that satisfies the given conditions is:
X = R (the set of real numbers)
d(x, y) = |x - y| (the absolute value of the difference between x and y)
A = [0, 1) (the closed interval from 0 to 1, including 0 but excluding 1)
Can a subset have limit points without an interior?In this example, the metric space X is the set of real numbers, and the distance function d(x, y) is defined as the absolute value of the difference between x and y. The subset A is the closed interval from 0 to 1, including 0 but excluding 1.
To show that every point in A is a limit point of A, we consider any point x in A. Since A contains all its limit points, any neighborhood of x contains points both in A and outside A. Hence, there will always be other points in A arbitrarily close to x, making x a limit point of A.
However, the interior of A, denoted int(A), refers to the set of all points in A that have a neighborhood entirely contained in A. In this case, int(A) is the empty set (∅). This is because every point in A, including 0, has points outside A arbitrarily close to it. Thus, no neighborhood of any point in A is entirely contained within A, resulting in an empty interior.
Limit points are points in a set that can be aproximated by other points in the set. In the given example, every point in the subset A = [0, 1) is a limit point of A because any neighborhood of a point in A contains infinitely many points in A. However, the interior of A is empty because no point in A has a neighborhood entirely contained within A. This example demonstrates that a set can have limit points without possessing an interior.

The dash triangle is a dilation image of the solar triangle with a center at the origin. Is a dilation and enlargement or a reduction find the scale factor of the dilation.
Because the scaling factor is a whole number, which is 3, the enlargement of the dashed triangle is a dilatation.
Recall:
Dilation enlarges or shrinks a figure or shape.The original image prior to any reduction or expansion is the image of a dilatation.The new image created following any necessary reduction or enlargement is the scale copy.Any side length of the new image divided by the corresponding side length of the old image gives the scale factor.The dilation is a reduction if the scale factor is a fraction.The dilatation is an enlargement if the scale factor is a whole number.Thus:
For the dashed triangle, measure the separation between the points (2, -2) and (0, -2).
(2, -2) to (0, -2) is separated by 2 units.Using the coordinates (6, -6) and (0, -6) for the solid triangle, calculate the equivalent distance:
(6, -6) and (0, -6) are separated by 6 units.Scale factor = 6/2 = 3
The dilation is an enlargement because the scale factor is a whole number.
In conclusion, the enlarged dashed triangle indicates a dilatation because the scale factor, which is 3, is a whole number.

Part A: When the biologist concluded her study, the radius of the algae was approximately 13.29 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 4 to d = 11, and what does it represent? (4 points)
{Please make sure to say what the piece of Part C represents and what the y-intercept of the graph of the function f(d) represent clearly}
The y - intercept of the graph represent the initial radius of the algae, the average rate of change is 0.63
What is the reasonable domain to plot the growth function1. Since the radius of the algae is increasing with time, a reasonable domain to plot the growth function would be the set of positive real numbers. In other words, d should be greater than or equal to zero.
2. The y-intercept of the graph of the function f(d) represents the initial radius of the algae, or the radius of the algae on day 0.
3. The average rate of change of the function f(d) from d = 4 to d = 11 is:
average rate of change = [f(11) - f(4)] / (11 - 4)
Substituting the given function, we get:
average rate of change = [7(1.06)^11 - 7(1.06)^4] / 7
average rate of change - 0.64
This represents the average increase in the radius of the algae per day between days 4 and 11.

Consider the financial statements for a publicly traded REIT, given above. In order for the REIT to maintain its tax exempt status, what is the minimum dividend it must pay per share? (assume no book tax differences) Ch21
a. $3.50 per share
b. $0.27 per share
c $44.10 per share
d $3.15 per share
The minimum dividend that the REIT must pay per share to maintain its tax-exempt status is $3.15 per share.
To determine the minimum dividend per share, we need to consider the requirements for a Real Estate Investment Trust (REIT) to maintain its tax-exempt status. According to the tax laws governing REITs, they are required to distribute at least 90% of their taxable income to shareholders in the form of dividends.
In this case, the net income of the REIT is $300,000. To calculate the taxable income, we need to add back the deduction for depreciation and amortization, as these are non-cash expenses. Therefore, the taxable income is $3,500,000 ($300,000 + $4,600,000).
To maintain the tax-exempt status, the REIT must distribute at least 90% of the taxable income to shareholders. Thus, the minimum dividend per share can be calculated as follows:
Minimum Dividend per Share = (Taxable Income / Number of Shares) * 90%
= ($3,500,000 / 1,000,000) * 90%
= $3.15 per share
In order for the REIT to maintain its tax-exempt status, it must pay a minimum dividend of $3.15 per share. By distributing at least 90% of the taxable income to shareholders, the REIT fulfills the requirements set by tax laws governing REITs.

Based on the given information, it seems that we are dealing with a linear transformation. Let's break down the steps to find the image of the vector v and the matrix representation of the linear transformation T with respect to the given bases.
Finding the image of vector v:
We apply the linear transformation T to the vector v:
T(v) = T(1, 9, 4) = (1 - 9, 9 - 4) = (-8, 5)
So, the image of vector v is (-8, 5).
Finding the matrix representation of T with respect to the given bases:
To find the matrix representation of T, we need to express the images of the basis vectors in terms of the new basis vectors.
T applied to the first basis vector:
T(1, 1, 1) = (1 - 1, 1 - 1) = (0, 0) = 0(1, 2) + 0(1, 1)
The coefficients of the basis vectors in the new basis are 0 and 0.
T applied to the second basis vector:
T(1, 1, 0) = (1 - 1, 1 - 0) = (0, 1) = 1(1, 2) + 0(1, 1)
The coefficients of the basis vectors in the new basis are 1 and 0.
T applied to the third basis vector:
T(0, 1, 1) = (0 - 1, 1 - 1) = (-1, 0) = -1(1, 2) + 0(1, 1)
The coefficients of the basis vectors in the new basis are -1 and 0.
Therefore, the matrix representation of T with respect to the given bases is:

For a quadratic equation, we start out seeking 2 solutions.
According to the statement
We have to find about the quadratic equation.
So, For this purpose, we know that the
Quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power
From the given information:
when we solve a quadratic equation, how many solutions should we always start out seeking.
Then
Here, we are required to search out out what number solutions to start out out seeking while solving a equation and also the condition for a quadratic graph not having zeros ( no x-intercepts).
Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.
And, a quadratic can haven't any zeros ( no x intercepts) if the roots of the equation are complex numbers.
A quadratic is one which has the very best degree of its variable ( usually x) to be 2.
Consequently, after we solve a quadratic, one should start out seeking two (2) solutions.
This is so because, the quantity of solutions to begin out seeking corresponds with the very best power of the experimental variable, X.
Therefore, where X³ occurs in an equation, it's cubic and consequently has 3 solutions.
Therefore, where X¹ occurs in an equation, it's linear and consequently has 1 solution.
And, where X² occurs in an equation, it's quadratic and consequently has 2 solutions.
It is possible to possess a quadratic with no zeros (i.e no x-intercepts).
So, For a quadratic equation, we start out seeking 2 solutions.
