you want to determine what uniform color shirt is the most preferred among 7th grade students. You survey 6 random students in your art class. 4 choose red, so you conlude that red us the preferred color of shirt. is your conclusion valid. explain.

Answers

Answer 1

The conclusion that red is the preferred color of shirt among 7th grade students based on a survey of 6 random students in an art class is not necessarily valid due to the small sample size, sampling bias, and lack of generalizability.

How to determine if the conclusion is valid.

The sample size of six pupils is tiny and may not be typical of the overall seventh-grade population. It's probable that the six students in the art class have different preferences or biases than the other seventh-grade students.

Also, the sample of six pupils is drawn at random from an art class rather than from the total 7th grade population. Students who are interested in art may have different preferences than students who are not. This can add bias into the sample.

Finally, the language of the survey question is critical. If the survey question specifically asks about the most chosen color of shirt among 7th grade kids in general, the conclusion that red is the most preferred color of shirt follows.

according to a 2009 reader's digest article, people throw away approximately of what they buy at the grocery store. assume this is the true proportion, and you plan to randomly survey 100 grocery shoppers to investigate their behavior. what is the probability that the sample proportion exceeds ? round your answer to three decimal places.

Answers

Answer: The problem states that the proportion of people who throw away a portion of what they buy at the grocery store is p = 0.4. We want to find the probability that the sample proportion exceeds a certain value, which we will denote as p-hat.

The sample size is n = 100, which is large enough to use the normal approximation to the binomial distribution.

The formula for the standard error of the sample proportion is:

SE = sqrt[p * (1 - p) / n]

Substituting the values given in the problem, we get:

SE = sqrt[0.4 * 0.6 / 100] = 0.049

To find the z-score corresponding to a sample proportion of , we use the formula:

z = (p-hat - p) / SE

Substituting the values given in the problem, we get:

z = ( - 0.4) / 0.049 = -2.04

Using a standard normal table, we find that the probability of obtaining a z-score of -2.04 or lower is 0.0207. Therefore, the probability that the sample proportion exceeds is approximately 0.0207, rounded to three decimal places.

Charles correctly answered 23 questions on a test, receiving a grade of 92%. How many questions were on the test?

Answers

Answer:

Let's start by using a proportion to find the total number of questions on the test. We know that Charles answered 23 questions correctly and received a grade of 92%, which means he missed 8% of the questions.

Let x be the total number of questions on the test. Then 8% of the questions that Charles missed can be expressed as 0.08x.

The number of questions that Charles answered correctly plus the number of questions he missed must add up to the total number of questions on the test:

23 + 0.08x = x

Simplifying and solving for x, we get:

0.92x = 23

x = 23 / 0.92

x ≈ 25

Therefore, the total number of questions on the test was approximately 25.

As association class is frequently required for what kind of relationship?
a. zero to one c. many to many
b. one to many d. zero to many

Answers

An association class is frequently required for a many-to-many relationship.

In object-oriented programming, an association class is a class that is used to represent an association between two or more other classes. An association class is typically used when the relationship between the other classes is many-to-many, which means that each instance of one class can be associated with multiple instances of another class, and vice versa.

For example, consider a database that stores information about students and the courses they are enrolled in. Each student can be enrolled in multiple courses, and each course can have multiple students.

To represent this many-to-many relationship between students and courses, we can create an association class called "Enrollment" that has attributes such as the date of enrollment and the grade received. The Enrollment class would have a many-to-one relationship with both the Student class and the Course class.

Verify that fxy = fyx for the following function. f(x,y)=e*+y+3

Answers

To verify that fxy = fyx for the given function f(x,y)=e^(x+y+3), we need to find the partial derivatives of f with respect to x and y, and then check if they are equal.

Let's begin by finding the partial derivative of f with respect to x (f_x): f_x = (∂f/∂x) = (∂/∂x) e^(x+y+3) = e^(x+y+3) * (∂/∂x) (x+y+3) [using chain rule] = e^(x+y+3)

Now, let's find the partial derivative of f with respect to y (f_y): f_y = (∂f/∂y) = (∂/∂y) e^(x+y+3) = e^(x+y+3) * (∂/∂y) (x+y+3) [using chain rule] = e^(x+y+3)

Now, let's find the mixed partial derivative of f with respect to x and y (f_xy): f_xy = (∂^2 f/∂y∂x) = (∂/∂y) e^(x+y+3) = e^(x+y+3) * (∂/∂y) (x+y+3) [using chain rule] = e^(x+y+3)

Similarly, the mixed partial derivative of f with respect to y and x (f_yx) can be found as: f_yx = (∂^2 f/∂x∂y) = (∂/∂x) e^(x+y+3) = e^(x+y+3) * (∂/∂x) (x+y+3) [using chain rule] = e^(x+y+3)

Now, we can see that fxy = fyx, as both are equal to e^(x+y+3). Hence, we have verified that the given function f(x,y)=e^(x+y+3) satisfies the condition fxy = fyx.

The measure of ∠CFE is 40°

How do we find ∠CEF?

To solve for triangle ∠CEF, we know that

Parallel to DE is BC

Arc length BD = 58°

Arc length DE = 142°

We can then draw a diameter across the center of the circle and give it a name as the first step. The diameter in this situation is line ZT.

The arcs BD and DE are split in half by the line ZT.

Which is:

Arc SC = 1/(1/2(arc BC) = 1/(58)

Arc SC = 29°

142 = 1/2(arc DE) + arc TE

Arc TE = 71°

Sum of the angles of a semicircle is 180 degrees: Arc SC + Arc CE + Arc TE

29° + Arc CE + 71° = 180°

Arc CE + 100° = 180°

Arc CE = 180-100

Arc CE = 80°

Angle inscribed equals half of angle intercepted

Savannah is playing a game with the spinner below. She gets to spin twice.

Write the sample space of all possible outcomes of these two spins.

Answers

The sample space of the spinner after spinning it twice is given by { (A, A) , (A, B ) , (A, C ), (A, D ) , ( B, A ), ( B, B ) , ( B, C ) ,  ( B, D ) ,  ( C, A ),

(C, B ) , ( C, C ) , (C, D ) , ( D, A ) , ( D, B ) , ( D, C ) , ( D, D ) }

Game played by Savannah using a spinner.

She spin the spinner twice.

To create a sample space for two spins of a spinner,

List all the possible outcomes of the first spin in one column.

And then list all the possible outcomes of the second spin in another column.

Then combine each outcome from the first column with each outcome from the second column to create all possible pairs of outcomes.

For example, suppose the spinner has 4 equally sized sections labeled A, B, C, and D.

The sample space for two spins would be,

{ (A, A) , (A, B ) , (A, C ), (A, D ) , ( B, A ), ( B, B ) , ( B, C ) ,  ( B, D ) , ( C, A ),

(C, B ) , ( C, C ) , (C, D ) , ( D, A ) , ( D, B ) , ( D, C ) , ( D, D ) }

Here, there are 16 possible outcomes for two spins of the spinner.

Therefore, the sample space of all possible outcomes of two spins is equal to  { (A, A) , (A, B ) , (A, C ), (A, D ) , ( B, A ), ( B, B ) , ( B, C ) ,  ( B, D ) ,  ( C, A ), (C, B ) , ( C, C ) , (C, D ) , ( D, A ) , ( D, B ) , ( D, C ) , ( D, D ) } .

Answers

We have shown that the diagonals of rectangle MNOP bisect each other and are congruent.

Describe Diagonal?

In geometry, a diagonal is a line segment connecting two non-adjacent vertices of a polygon, such as a triangle, quadrilateral, or higher-order polygon. For example, in a rectangle, the diagonals are the line segments connecting opposite corners.

A diagonal can also refer to a line segment connecting two opposite corners of a three-dimensional solid, such as a cube or rectangular prism.

In many cases, diagonals have important properties and can be used to solve geometric problems. For example, in a rectangle, the diagonals are congruent and bisect each other. In a regular polygon with n sides, the number of diagonals can be calculated using the formula (n(n-3))/2. The length of a diagonal in a right triangle can be found using the Pythagorean theorem.

To show that the diagonals of rectangle MNOP bisect each other, we need to prove that the midpoint of diagonal MP is the same as the midpoint of diagonal NO.

Let's find the coordinates of the midpoints of MP and NO:

Midpoint of MP:

((x1 + x2)/2, (y1 + y2)/2)

= ((-7 + 5)/2, (1 - 7)/2)

= (-1, -3)

Midpoint of NO:

((x1 + x2)/2, (y1 + y2)/2)

= ((5 - 7)/2, (1 - 7)/2)

= (-1, -3)

As we can see, the midpoint of MP and NO are both (-1, -3), which means the diagonals bisect each other.

To show that the diagonals of rectangle MNOP are congruent, we need to find the length of both diagonals and prove that they are equal.

Let's find the length of diagonal MP:

MP = √((5 - (-7))² + ((-7) - 1)²)

= √(12² + (-8²)

= √(144 + 64)

= √(208)

Let's find the length of diagonal NO:

NO = √((5 - (-7))² + (1 - (-7)²)

= √(12² + 8²)

= √(144 + 64)

= √(208)

As we can see, the length of both diagonals is sqrt(208), which means the diagonals are congruent.

Therefore, we have shown that the diagonals of rectangle MNOP bisect each other and are congruent.

In the second round, each of the 5 people from the first round hands out 5 fliers to 5 other people. So, there are now 5 x 5 = 25 people with fliers (including the original 5).

In the third round, each of the 25 people from the second round hands out 5 fliers to 5 other people. So, there are now 25 x 5 = 125 people with fliers (including the original 5 and the 25 from the second round).

In the fourth round, each of the 125 people from the third round hands out 5 fliers to 5 other people. So, there are now 125 x 5 = 625 people with fliers (including the original 5, the 25 from the second round, and the 125 from the third round).

Consider a two-period binomial model with risk-neutral prob- ability distribution p=0.6, q=0.4. Let V2 be the payoff for a derivative with: Va(ww.) = { s 1 if w1 = H, W2 = H or w1 = T, W2 =T 0 otherwise Find the price of this derivative.

Answers

To price the derivative using the two-period binomial model, we need to calculate the expected payoff of the derivative using the risk-neutral probabilities.

The possible outcomes for the two-period binomial model are H and T,  there are four possible states of the world: HH, HT, TH, and TT.

To calculate the expected payoff we need to calculate the probability of each state occurring. The probability of HH occurring is pp=0.60.6=0.36, the probability of HT and TH occurring is pq+qp=0.60.4+0.40.6=0.48, and the probability of TT occurring is qq=0.40.4=0.16.

Next, we can calculate the expected payoff in HH and TT states, the derivative pays off 1, and in the HT and TH states, the derivative pays off 0. The expected payoff of the derivative in the HH and TT states is 10.36=0.36, and the expected payoff in the HT and TH states is 00.48=0.

We need to discount the expected payoffs back to time 0 using the risk-neutral probabilities.

The probability of that state occurring multiplied by the discount factor, which is 1/(1+r), where r is the risk-free interest rate.

Since this is a risk-neutral model, the risk-free interest rate is equal to 1. Therefore, the risk-neutral probability of each state occurring is

HH: 0.36/(1+1) = 0.18

HT/TH: 0.48/(1+1) = 0.24

TT: 0.16/(1+1) = 0.08

Finally, we can calculate the price of the derivative

Price = 0.181 + 0.240 + 0.240 + 0.081 = 0.26

Therefore, the price of the derivative is 0.26.

Answers

The area of 0.6808 to its left using the Standard Normal Table.

steps: 1. Identify the area: In this case, the area to the left of the z-score is given as 0.6808.

2. Consult the Standard Normal Table: This table shows the area to the left of various z-scores, ranging from negative to positive values.

3. Locate the closest area value: Look for the value in the table that is closest to the given area (0.6808). The table is typically organized into rows and columns, with the row header representing the first two digits of the z-score and the column header representing the third digit.

4. Identify the z-score: Once you've found the closest area value, determine the corresponding z-score by combining the row and column headers where the value is located.

Upon checking the Standard Normal Table, the closest area value to 0.6808 is 0.6800, which corresponds to a z-score of 0.47.

Keep in mind that the Standard Normal Table may not have the exact area value of 0.6808, so you need to find the closest possible value.

I just need the perimeter

Example #2 - Coordinate Perimeter/Area Calculate the area and perimeter of the shape shown. Determine the: Perimeter Area​

Answers

Using composite figures, we can find that the area of the shape is 18unit² and the perimeter of the shape is 20 + √8 units.

Define composite figures?

A composite shape is a shape that is made by connecting a few polygons to form a different shape. These shapes or figures can be formed from a variety of shapes, including triangles, squares, quadrilaterals, etc. Divide a composite item into basic forms such a square, triangle, rectangle, or hexagon to get its area.

In essence, a composite shape is a combination of fundamental shapes. It goes by the name's "composite" or "complex" shapes.

In this composite figure,

We have 2 rectangles and a triangle.

Dimension of rectangle:

Base = 2units

Height = 2 units.

Hypotenuse = √ (2² + 2²)

= √8

Area of the triangle = 1/2 × b × h

= 1/2 × 2 × 2

= 2unit².

Now, the rectangles are equal in shape and size.

Dimensions are:

Length = 4 units

Breadth = 2 units.

Area = l × b

= 4 × 2

= 8unit².

We have 2 rectangles so total area = 2 × 8

= 16unit².

Total area of the shape = area of triangle + area of 2 rectangles

= 2 + 16

= 18unit²

Now coming to the perimeter of the shape, we have to find the sum of the measure of the sides of the shape:

So, we have

2 + 4 + 2 + 6 + 6 + √8

= 20 + √8 units.
