Answer:

Step-by-step explanation:

The 90% confidence interval for the population proportion of adults who believe in UFOs is (0.309, 0.339).

C. With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.

To construct a 90% confidence interval for the population proportion of adults who believe in UFOs, we can use the formula:

Confidence Interval = Sample Proportion ± Margin of Error

First, we calculate the sample proportion:

Sample Proportion \(\hat{p}\) = Number of adults who believe in UFOs / Total number of adults surveyed = 736 / 2266 ≈ 0.324

Next, we need to calculate the margin of error.

Since we are dealing with a large sample size, we can use the formula for a 90% confidence interval:

Margin of Error\(= Z \times \sqrt{(\hat{p} \times (1 - \hat{p}) / n)}\)

Here, Z represents the z-value for a 90% confidence level, which corresponds to a z-value of 1.645. n represents the sample size.

Margin of Error\(= 1.645 \times \sqrt{(0.324 \times (1 - 0.324) / 2266)}\) ≈ 0.015

Finally, we can construct the confidence interval:

Confidence Interval = 0.324 ± 0.015 = (0.309, 0.339)

Therefore, the 90% confidence interval for the population proportion of adults who believe in UFOs is (0.309, 0.339).

Now, let's interpret the results.

The correct answer is:

C. With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.

This means that we are 90% confident that the true proportion of adults who believe in UFOs falls within the range of 0.309 to 0.339.

The extra amount that Robby is to pay in interest to purchase the television is calculated as: $98

To calculate the extra amount paid in interest, you need to determine the total cost of the loan, including the interest, and subtract the original amount borrowed.

Here's the formula to calculate the extra amount paid in interest:

Extra Amount Paid in Interest = Total Cost of Loan - Original Amount Borrowed

Where, Total Cost of Loan = Original Amount Borrowed + Interest

To calculate the interest, you can use the following formula:

Interest = Original Amount Borrowed x Interest Rate x Time

The interest on the cash advance is calculated as follows:

$350 x 28% = $98

So, the total amount Robby will pay for the television after interest is:

$350 + $98 = $448

Therefore, the extra amount Robby will pay in interest to purchase the television is:

$448 - $350 = $98

Answer:

The probability that each player will receive three picture cards = 0.0324

Step-by-step explanation:

As given,

A deck of 52 cards contains 12 picture cards

Remaining card = 52 - 12 = 40

So,

Total number of ways in which 12 picture card is distributed = \(\frac{12!}{3! 3! 3! 3!}\)

Now,

The Total number of ways in which Remaining cards are distributed = \(\frac{40!}{10! 10! 10! 10!}\)

So,

Total number of ways of getting 3 picture card and remaining card = \(\frac{12!}{3! 3! 3! 3!}\)× \(\frac{40!}{10! 10! 10! 10!}\)

= \(\frac{12! 40!}{(3!)^{4} (10!)^{4} }\)

Now,

Total number of ways to distribute 52 cards so that each people get 13 card = \(\frac{52!}{13! 13! 13! 13!} = \frac{52!}{ (13!)^{4} }\)

∴ The probability = \(\frac{\frac{12! 40!}{(3!)^{4} (10!)^{4} }}{\frac{52!}{(13!)^{4} }}\)

                            = \(\frac{12! 40!}{(3!)^{4} (10!)^{4} }\)×\(\frac{(13!)^{4} }{ 52! }\)

                           = \(\frac{12! 40!}{(3!)^{4} (10!)^{4} }\)×\(\frac{(13.12.11.10!)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41.40! }\)

                           = \(\frac{12!}{(3!)^{4} }\)×\(\frac{(13.12.11)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}\)

                           = \(\frac{479,001,600}{(6)^{4} }\)×\(\frac{(1716)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}\)

                           = 0.0324

∴ we get

The probability that each player will receive three picture cards = 0.0324

The volume of the rectangular prism is 900 cubic inches.

What is prism?

A prism is a three-dimensional geometric shape that has two identical ends, called bases, and flat, parallel sides that connect the bases.

The formula for the volume of a rectangular prism is:

Volume = Base Area x Height

where the base area is the product of the length and width of the base. Since we are given the base area as 60 square inches, we can write:

Base Area = length x width = 60 sq in

The volume of a rectangular prism is given by multiplying the area of the base by the height. In this case, the height is given as 15 inches, and the area of the base is given as 60 square inches. Therefore, the volume of the rectangular prism can be calculated as follows:

Volume = Base Area x Height

Volume = 60 sq in x 15 in

Volume = 900 cubic inches

Therefore, the volume of the rectangular prism is 900 cubic inches.

The length of the diameter of the sphere is 30 cm.

The surface area of a sphere is given by the formula:

\(A = 4\pi r^2\)

where A is the surface area and r is the radius of the sphere.

We are given that the surface area of the sphere is 900π cubic cm. Therefore:

\(A = 4\pi r^2 = 900\pi\)

Dividing both sides by 4π, we get:

\(r^2 = 225\)

Taking the square root of both sides, we get:

r = 15

The diameter of the sphere is twice the radius, so:

d = 2r = 30

Option of the matrices a, b, and d are non symmetric.

Symmetric matrices are those matrices that have equal dimensions, i.e. the number of rows is same as the number of columns. They are also known as square matrices.

It is provided that A and B are symmetric n × n matrices.

To multiply two matrices of different order, the number of rows of the first matrix must be same as the number of columns of the second matrix.

Suppose X is a 2 × 3 matrix and Y is a 3 × 2.

Then the product AB will be a n × n matrix.

(a) A= C+CT

Thus the sum of matrix A and B will be a n × n matrix.

Thus, the matrix A is non symmetric.

(b) B = C-CT

So, matrix D will also be a n × n matrix.

Thus, the matrix D is non symmetric.

(c) D = CTC = (CT) × C

Then the product CT will be a n × n matrix.

The next step would be to multiply CT and C.

Both are n × n matrices.

Thus, the matrix D is symmetric.

(d) E = CTC - CCT

Then he product CT will be a n × n matrix.

Similarly, the product CT will be a n × n matrix.

Thus, the matrix E is non symmetric.

Similalry,

(e) F = (I +C)(I + CT

Thus, the matrix F is symmetric.

(f) G = (I +C)(I -CT)

Thus, the matrix G is symmetric.

Step-by-step explanation:

First of all, let's find the shaded region for our given inequality:

y > ⅓x +4

To determine whether the origin is included in the shaded region, let's put in the value of x and y at the origin (0,0)

Plugging in x = 0 and y = 0 into the inequality gives;

0 > ⅓(0) + 4

0 > 4

0 is not greater than 4 like it states and thus it is false

Therefore, we conclude that the point (0,0) which is the origin is not included in the shaded region

It is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a Wide range of factors

As an AI language model, I do not have access to up-to-date information about salaries of coaches in Jacksonville. However, in general, the salaries of coaches vary widely depending on a number of factors, such as the type of sport, the level of competition, the location, the success of the team, and the budget of the institution.

In terms of tennis and football, football is generally considered to be a more popular and high-profile sport than tennis in the United States, which could result in higher salaries for football coaches at the collegiate level. Football also typically generates more revenue and has larger budgets for athletic programs, which could also influence the salaries of coaches.

However, there are also factors that could affect the salaries of tennis coaches. For example, if a tennis program has a particularly successful season or has produced successful players, the coach may negotiate a higher salary. Additionally, some colleges may place a greater emphasis on tennis or have larger budgets for tennis programs, which could also impact the salaries of coaches.

Overall, it is difficult to make a general statement about whether tennis coaches generally get paid more than football coaches in Jacksonville or elsewhere, as the salaries of coaches are influenced by a wide range of factors. It is also important to note that salaries can vary widely between individual institutions, even within the same sport, and that negotiations between coaches and their institutions can play a significant role in determining salaries.
