The 95% confidence interval for the population proportion favoring stricter gun control laws in the district is approximately 0.4612 to 0.5188. This means that 95% are confident that the true proportion of voters in the population who favor stricter gun control laws falls within this range.

The 95% confidence interval for the population proportion favoring stricter gun control laws based on a poll of 1,100 voters in which 49% of them favored stricter laws.

To find the confidence interval, follow these steps:

1. Determine the sample proportion (p-hat): p-hat = favorable votes / total votes = 0.49.

2. Determine the sample size (n): n = 1,100 voters.

3. Calculate the standard error (SE): \(SE = \sqrt(p-hat \times (1 - p-hat) / n)\)

\(= \sqrt(0.49 \times (1 - 0.49) / 1100) \approx 0.0147.\)

4. Find the critical value (z) for a 95% confidence interval: z = 1.96 (from a standard normal distribution table).

5. Calculate the margin of error (ME): \(ME = z \times SE = 1.96 \times 0.0147 \approx 0.0288.\)

6. Find the lower and upper limits of the confidence interval:

Lower limit = p-hat - ME = \(0.49 - 0.0288 \approx 0.4612;\)

Upper limit = p-hat + ME = \(0.49 + 0.0288 \approx 0.5188.\)

In conclusion, the 95% confidence interval for the population proportion favoring stricter gun control laws in the district is approximately 0.4612 to 0.5188. This means that we are 95% confident that the true proportion of voters in the population who favor stricter gun control laws falls within this range.

The sum of the first 10 terms is approximately 414.66667. The estimated error is less than or equal to 0.00008.

The sum of the first 10 terms of the series can be approximated by evaluating the expression 9 + n\(^5\) for n = 1 to 10 and summing the results.

The calculated sum is 1 + 32 + 243 + 1024 + 3125 + 7776 + 16807 + 32768 + 59049 + 100000, which equals 41466667.

To estimate the error, we can use the remainder term formula Rn ≤ (1/x\(^5\)) where x is the value of n.

Substituting x = 10, we get R10 ≤ 1/10\(^5\) = 0.00001.

Rounding the estimated error to five decimal places, we have an error of 0.00001.

The vertex of the parabola is given as (3,2), which means that the squared term is (x-3)^2.

The equation of the graph below is: y = -(x - 3)^2 + 2

This is because the graph is a parabola that opens downwards, which means it has a negative coefficient for the squared term. The vertex of the parabola is given as (3,2), which means that the squared term is (x-3)^2. The constant term is 2, which is added to shift the parabola up by 2 units. Thus, the equation of the parabola is y = -(x-3)^2 + 2.

Option (b) y = -(x + 2)^2 + 2 would also open downwards, but its vertex would be at (-2,2) and not (3,2) as given in the graph. Option (c) y = (x-2)^2 + 2 and option (d) y = (x+3)^2 + 2 would both open upwards, which is not consistent with the graph.

Based on the given data and the median travel times, Bus 47 typically has the faster travel time compared to Bus 18.

To compare the travel times and determine which bus typically has the faster travel time, we can examine the measures of center, specifically the median and the mean, for each bus.

For Bus 18:

Median: 13

Mean: We don't have enough information to calculate the mean.

For Bus 47:

Median: 16

Mean: We don't have enough information to calculate the mean.

Comparing the medians, we see that Bus 47 has a higher median travel time (16) compared to Bus 18 (13).

This suggests that, on average, the travel times for Bus 47 are higher than those for Bus 18.

1. The ratio of the surface area to volume of the cube = 3/ 5

2. The ratio of the surface area to volume of the cuboid = 113/ 62

Surface area and volume of a figure.

The surface area of a given figure is the area of the total external boundary of the figure. While the volume of a figure is the quantity of substance that can fill up the figure.

To solve the question, we have;

1. The surface area of a cube = 6a

where: a = length x length

              = 10 * 10

            a = 100 square centimeters

So that;

surface area of the cube = 6*100

                               = 600 sq cm

ii. Volume of a cube = l^3

                        = 10^3

volume of the cube = 1000 cubic centimeters

iii. The ratio of its surface area to volume = 600/ 1000

                                        = 6/ 10 = 3/ 5

2. The surface area of a cuboid = 2a + 2b + 2c

                = 2(a + b + c)

where a = b = c = length * width

a = length x width

  = 4*2

a = 8 sq. m

b = length x width

  = 6.2 x 4

b = 24.8 sq. m

c = length x width

      6.2 x 2

c = 12.4 sq. m

Surface area of the cuboid = 2(8 + 24.8 + 12.4)

                      = 90.4 sq. m

ii. volume of a cuboid = length x width x height

                             = 6.2 x 4 x 2

                             = 49.6 cubic meters

iii. The ratio of surface area to volume of the cuboid = 90.4/ 49.6

I used GeoGebra to make the graph. Desmos is another option I recommend.

The equation we graph is y = (1/2)^x since we're splitting the paper in half each time. This is an exponential decay function. Note how the curve slopes downhill when moving to the right.

It appears the curve touches or crosses the x axis; which is misleading. Instead, the curve is getting closer and closer to this horizontal asymptote. It will never reach the x axis. Think of it like an electric fence.

As the graph indicates, we don't have a straight line. Therefore, the function isn't linear. It's a nonlinear curve.

Step-by-step explanation:

In cylindrical coordinates, the equations can be written as:

(a) \(9r^2 - z^2 = 5\)

(b) 6r cos(θ) - r sin(θ) + z = 7

The first equation, \(9x^2 + 9y^2 - z^2 = 5\), represents a quadratic surface in Cartesian coordinates. To express it in cylindrical coordinates, we need to substitute the Cartesian variables (x, y, z) with their respective cylindrical counterparts (r, θ, z).

The variables r and θ represent the radial distance from the z-axis and the azimuthal angle measured from the positive x-axis, respectively. The equation becomes \(9r^2 - z^2 = 5\) in cylindrical coordinates, as the conversion formulas for x and y are x = r cos(θ) and y = r sin(θ).

The second equation, 6x - y + z = 7, is a linear equation in Cartesian coordinates. Using the conversion formulas, we substitute x with r cos(θ), y with r sin(θ), and z remains the same. After the substitution, the equation becomes 6r cos(θ) - r sin(θ) + z = 7 in cylindrical coordinates.

Expressing equations in cylindrical coordinates can be useful in various scenarios, such as when dealing with cylindrical symmetry or when solving problems involving cylindrical-shaped objects or systems.

By transforming equations from Cartesian to cylindrical coordinates, we can simplify calculations and better understand the geometric properties of the objects or systems under consideration.

The conversion from Cartesian coordinates (x, y, z) to cylindrical coordinates (r, θ, z) is given by:

x = r cos(θ)

y = r sin(θ)

The basis for the eigenspace corresponding to the eigenvalue λ = 2 is {[1, 1, 0]}.

To find a basis for the eigenspace corresponding to the eigenvalue λ = 2, we need to solve the equation (A - λI)X = 0, where A is the given matrix, λ is the eigenvalue, X is the eigenvector, and I is the identity matrix.

Given matrix A:

[2 -1 1]

[0 -3 -4]

[0 8 9]

Eigenvalue: λ = 2

We subtract λI from A to get (A - λI):

[2 - 1 1]

[0 -3 -4]

[0 8 9] - 2 * [1 0 0]

[0 1 0]

[0 0 1]

Simplifying, we have:

[2 - 1 1]

[0 -3 -4]

[0 8 9] - [2 0 0]

[0 2 0]

[0 0 2]

= [0 -1 1]

[0 -5 -4]

[0 8 7]

Now we need to solve the equation (A - λI)X = 0 to find the eigenvectors.

Substituting λ = 2 into (A - λI), we have:

[0 -1 1]

[0 -5 -4]

[0 8 7]X = 0

To solve this homogeneous system of equations, we can use row reduction. We start with the augmented matrix:

[0 -1 1 0]

[0 -5 -4 0]

[0 8 7 0]

Performing row operations, we can obtain the row-echelon form:

[0 -1 1 0]

[0 0 -1 0]

[0 0 0 0]

From this, we can write the system of equations:

-x + y = 0 ---> x = y

-z = 0 ---> z = 0

0 = 0 ---> no restriction on any variable

In vector form, the eigenvectors can be expressed as:

X = [y, y, 0] = y[1, 1, 0]

This indicates that for any scalar value y, the vector [y, y, 0] is an eigenvector corresponding to the eigenvalue λ = 2.

Therefore, a basis for the eigenspace corresponding to λ = 2 is { [1, 1, 0] }.

In summary, the basis for the eigenspace corresponding to the eigenvalue λ = 2 is {[1, 1, 0]}.

The answers are : mean = 0, standard deviation = 1, skewed to the right.

And the correct option is A.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

The mean finish time for 48 racers who finished the grueling 50 km cross-country ski race at the Olympics is 2.164 hours,

and the standard deviation is 0.85 hours.

That means, we have;

μ = 2.164 and σ = 0.85

So, the z-score;

z = (\(\bar x\) - μ) / σ

z =  (\(\bar x\) - 2.164) / (0.85)

The mean of z-score is,

E(z) = E (\(\bar x\)) - μ / σ

E(z) = μ  - μ / σ

E(z) = 0 / σ

E(z) = 0

SD of z-score is,

SD (z) = SD(\(\bar x\)) - μ / σ

SD (z) = SD(\(\bar x\)) - 0 / σ

SD (z) = SD(\(\bar x\)) / σ

SD (z) = σ / σ

SD (z) = 1

Median of the distribution \(\bar x\) ≈ 2.13.

It responds to cumulative relative frequency of 0.50.

Median < mean

The coefficient of skewness is given by;

S = 3 (median - mean) / σ

S = 3 (2.164 - 2.13) / σ

S > 0

That means, the shape of the distribution of z - score is skewed to the right.

Therefore,  mean = 0, standard deviation = 1, skewed to the right.

The probability of the spinner landing on 5 is 1/8.

The spinner is divided into 8 equal sections, and each section represents a number from 1 to 8. Since there is only one section with the number 5, the favorable outcome is landing on 5.

To calculate the probability, we need to determine the ratio of the favorable outcomes (landing on 5) to the total number of possible outcomes (numbers 1 to 8 on the spinner).

The total number of possible outcomes is 8, as there are 8 numbers on the spinner. Therefore, the probability of landing on 5 can be calculated as follows:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 1 (favorable outcomes) / 8 (total possible outcomes)

Simplifying the expression:

Probability = 1/8
