hope it helps!

we have to convert the mixed fractions to improper fraction and do the arithmetic as follows:

\(\frac{25}{2}-(-\frac{9}{2} ) =\frac{25}{2} +\frac{9}{2}=\frac{34}{2} =17\)

\(12\frac{1}{2} -(-4\frac{1}{2} )=?\)

The fractions are represented in mix fractions. Therefore, let's convert it it to improper fractions before doing the arithmetic.

\(12\frac{1}{2} = \frac{25}{2}\)

\(-4\frac{1}{2} = -\frac{9}{2}\)

Therefore,

\(\frac{25}{2}-(-\frac{9}{2} ) =\frac{25}{2} +\frac{9}{2}\)

Note - × -  = +

Therefore,

\(\frac{25}{2} +\frac{9}{2} =\frac{25+9}{2}\)

\(\frac{25+9}{2} = \frac{34}{2}=17\)

Therefore, the arithmetic is 17

The Retail Positioning Matrix is a tool used in retail marketing that helps to visualize and evaluate potential positioning strategies. It is composed of two main dimensions: price and quality.

While quality relates to the perceived value of a product or service in terms of its features, advantages, and performance, price is the amount of money consumers are prepared to pay for a good or service.

High price/high quality, high price/poor quality, low price/high quality, and low price/low quality are the four quadrants that the matrix divides price and quality into.

Retailers can choose which positioning approach will work best in a particular market by looking at each of these four quadrants, which each feature a different positioning strategy.

The true statement of the parabola is (a) directrix will cross through the positive part of the y-axis.

Parabolas are examples of a conic section such that it is formed by the intersection of a cone with a plane parallel to its side.

From the question, the given parameters are:

Vertex = (0,0)

Focus = Negative side of the y-axis

A parabola has quite a number of forms, one of these forms is the general form.

The general form is represented as:

(x - h)^2 = 4p(y - k)

The vertex of the parabola is

(h, k) = (0, 0).

So, we have:

(x - 0)^2 = 4p(y - 0)

Evaluate the difference

x^2 = 4py

Since the focus is on the negative side, the value of p will be negative.

Also, because the vertex is at the origin, the directrix of the parabola will cross through the positive part of the y-axis.

This means that the true statement of the parabola is (a) directrix will cross through the positive part of the y-axis.

Step-by-step explanation:

The probability of having exactly 4 students arriving during a randomly selected office hour is approximately 0.1264, or 12.64%.

The given problem is an example of a Poisson distribution, where the probability of a certain number of events occurring in a fixed interval of time is proportional to the average number of events in that interval.

The probability of having exactly 4 students arriving during an office hour can be calculated using the Poisson distribution formula:

P(X=4) = (e^(-λ) × λ⁴) / 4!

where λ is the average number of events in the given interval, which is 3.7 in this case.

Substituting the values, we get:

P(X=4) = (e^⁽⁻³.⁷⁾ × 3.7⁴) / 4!

P(X=4) = 0.1264

Answer:

not linear since all first differences are not equal

Step-by-step explanation:

To find the first differences, subtract each y value from the next y value.

Use only y values.

here are the 4 first differences you need to calculate.

1 - 0 = 1

4 - 1 = 3

9 - 4 = 5

16 - 9 = 7

Now you place them in the appropriate column in the table.

x   y      first difference

0   0       1

1   1         3

2   4       5

3   9       7

4   16

If the first differences were all equal, the function would be a linear function.

In this case, the first differences are all different, 1, 3, 5, 7, so the function is not linear.

Answer:

The answer is 7/24

Step-by-step explanation:

Answer:

a = 16

Step-by-step explanation:

6 = a/4 + 2

4 = a/4            Subtract 2 from both sides

16 = a                 Multiply 4 to both sides

Answer: a=16

Step by Step Explanation

Step 1: Switch sides so that the product is last. It is now a/4=2=6

Step 2: Subtract 2 from both sides.    2-2=0      6-2=4

Step 3: Now we have a/4=4. Multiply both sides by 4.  

Step 4: 4 times 4 equals 16.

a=16

To check ur answer, plug it into the equation. 16/4+2=6

Let's check if it's right.

16/4=4    4+2=6      6=6   This is correct

3/8 gallon of white paint

2 7/8 gallon of blue paint

11/4 gallon of red paint

First, let’s answer the first question.

Francis has made _____ gal of paint when he first mixes the three colors.

Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.

Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.

Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)

The cosine form of the function 10sin(wt - 40)  is 10cos(wt - 50).

The cosine form of the function 10sin(wt - 40) can be found using the identity sin(x - y) = sin(x)cos(y) - cos(x)sin(y).

By applying this identity to the given function, we can rewrite it in terms of cosine.

10sin(wt - 40) = 10(sin(wt)cos(40) - cos(wt)sin(40))

Now, we can use the fact that cos(90 - x) = sin(x) and sin(90 - x) = cos(x) to further simplify the expression.

10(sin(wt)cos(40) - cos(wt)sin(40)) = 10(sin(wt)sin(50) + cos(wt)cos(50))

Finally, we can use the identity cos(x + y) = cos(x)cos(y) - sin(x)sin(y) to rewrite the expression in terms of cosine.

10(sin(wt)sin(50) + cos(wt)cos(50)) = 10cos(wt - 50)

Therefore, the cosine form of the function 10sin(wt - 40) is 10cos(wt - 50).

The coordinate vector of g(t) relative to the basis F is (-2, 1, -2).

We can do this by equating the coefficients of q(t) and the linear combination of p₁(t), p₂(t), and p₃(t) and solving for c₁, c₂, and c₃. Specifically, we want to solve the system of equations:

c₁ + 2c₂ + 2c₃ = -8

c₁ + 0c₂ + 0c₃ = 0

2c₁ - 3c₂ + 2c₃ = -10

The first equation comes from equating the coefficients of t⁰ in q(t) and the linear combination, the second equation from equating the coefficients of t¹, and the third equation from equating the coefficients of t².

Solving this system of equations, we get c₁ = -2, c₂ = 1, and c₃ = -2. Therefore, we can write q(t) as -2p₁(t) + p₂(t) - 2p₃(t). This means that the coordinate vector of q(t) with respect to the basis F is (-2, 1, -2), which is the vector of scalars that we used to form the linear combination of p₁(t), p₂(t), and p₃(t) that equals q(t).

The matrix can be diagonalized, and the correct choice is B. For P= ⎡⎣​3−110​11​⎤⎦, D= ⎡⎣​393​000​⎤⎦.

To diagonalize a matrix, we need to find its eigenvectors and use them to construct a matrix P, where the columns of P are the eigenvectors. The diagonal matrix D is formed by placing the eigenvalues on the diagonal.

First, we find the eigenvalues λ by solving the characteristic equation det(A - λI) = 0, where A is the given matrix and I is the identity matrix. By calculating the determinant, we have (33 - λ)(9 - λ) - (-3)(18) = 0, which simplifies to λ^2 - 42λ + 315 = 0. Solving this quadratic equation gives λ = 3 and λ = 9.

Next, we find the corresponding eigenvectors. For λ = 3, we solve the equation (A - 3I)v = 0, where v is the eigenvector. This leads to the eigenvector v = ⎡⎣​3−110​⎤⎦. For λ = 9, we solve (A - 9I)v = 0, which gives v = ⎡⎣​11​1​⎤⎦.

We construct matrix P by using the eigenvectors as columns: P = ⎡⎣​3−110​11​⎤⎦. The diagonal matrix D is formed by placing the eigenvalues on the diagonal: D = ⎡⎣​393​000​⎤⎦.

Therefore, the correct choice is B. For P= ⎡⎣​3−110​11​⎤⎦, D= ⎡⎣​393​000​⎤⎦.

The expected value of the sampling distribution of p is 0.8.

A statistic's probability distribution is called a sampling distribution when it is calculated from a larger number of samples taken from a particular population. The distribution of frequencies for a variety of outcomes that could possibly occur for a statistic of a population is known as the sampling distribution of that population.

The normal distribution, which is also known as the Gaussian distribution, is symmetric about the mean. It demonstrates that data close to the mean occur more frequently than data far from the mean. The normal distribution is depicted graphically as a "bell curve."
