The firework is an illustration of the equation of a parabola.

The x-intercepts are 0 and 78, the y-intercept is 0, and the vertex is (39,760.5)

The casings hit the ground after 78 seconds.

This means that, a point on the graph is:

\(\mathbf{(x,y) = (78,0)}\)

The firework exploded at a maximum of 760.5.

This means that, the vertex is:

\(\mathbf{(h,k) = (39,760.5)}\)

The equation of a parabola is:

\(\mathbf{y = a(x - h)^2 + k}\)

So, we have:

\(\mathbf{0 = a(78 - 39)^2 + 760.5}\)

\(\mathbf{0 = a(39)^2 + 760.5}\)

Subtract 760.5 from both sides

\(\mathbf{a(39)^2 =- 760.5}\)

\(\mathbf{1521a =- 760.5}\)

Solve for a

\(\mathbf{a =- \frac{760.5}{1521}}\)

\(\mathbf{a =- 0.5}\)

Substitute \(\mathbf{a =- 0.5}\) and \(\mathbf{(h,k) = (39,760.5)}\) in \(\mathbf{y = a(x - h)^2 + k}\)

\(\mathbf{y = -0.5(x - 39)^2 + 760.5}\)

See attachment for the graph of \(\mathbf{y = -0.5(x - 39)^2 + 760.5}\).

From the graph:

From the equation:

Hence, the x-intercepts are 0 and 78, the y-intercept is 0, and the vertex is (39,760.5)

The estimated margin of error for the survey of the students would be 5%.

Margin of error is a percentage that reflects the degree of inaccuracy inherent in the sample of any survey. It suggests how far the sample estimate is likely to be from the real population value. It gives a measure of the quality of a sample, indicating how far it is from a true representation of the population.

The quick method to estimate the margin of error for a survey with a 95% level of confidence is:

ME = 1 / √n

Where, ME = Margin of error and n = Sample size

Using the given data, the sample size n = 375

Thus,

ME = 1 / √375 = 0.0519 ≈ 5%

Therefore, the estimated margin of error would be approximately 5%.

The number of ways that A and B can have subsets is the product of the number of subsets of A and the number of subsets of B, or (2^n) * (2^m) = 2^(n+m).

A set is a collection of distinct objects, and a subset is a set that contains only elements that are also in another set. If set A is a subset of set B, then all elements of A are also elements of B.

The number of subsets of a set with n elements is 2^n. So, if set A has n elements and set B has m elements (where m > n), the number of subsets of A is 2^n and the number of subsets of B is 2^m. The number of ways that A and B can have subsets is the product of the number of subsets of A and the number of subsets of B, or (2^n) * (2^m) = 2^(n+m).

So the dimensions of the box are:

Length: 20m

Width: 10m

Height: 10m

We can use the information provided in the problem to set up a system of equations. Let H be the height, L be the length, and W be the width.

From the problem, we know:

L = 2H (the length is twice the height)

W = L - 10 (the width is 10 meters less than the length)

2HW + 2LW + 2LH = 10WH (the surface area is 10 times the width times the height)

We can substitute the first and second equations into the third one to obtain:

2H(2H-10) + 2(2H)(2H-10) + 2(2H)(2H) = 10H(2H-10)

Solving this equation we get H = 10m

With this value we can solve for the other dimensions:

L = 2H = 2 * 10 = 20m

W = L - 10 = 20 - 10 = 10m

So the dimensions of the box are:

Length: 20m

Width: 10m

Height: 10m

The creation of strata, which are proportional to the size

What is Sampling?

Sampling refers to the process of selecting a subset of individuals or items from a larger population, in order to study and draw conclusions about the population. Sampling is often used in research, marketing, and other fields to collect data from a smaller group, which is then analyzed to make inferences or predictions about the larger population.

There are several different methods of sampling, including random sampling, stratified sampling, cluster sampling, and convenience sampling. Each method has its own strengths and weaknesses, and the choice of sampling method will depend on the research question, the size of the population, and other factors.

A sample is biassed when it does not accurately reflect the population that it is supposed to represent. A sample statistic (such the sample mean or proportion) that consistently overvalues or undervalues the real population parameter can result from this. The sample technique, sampling frame, and nonresponse are only a few examples of the variables that might lead to bias. In order for the sample to effectively represent the population and for valid statistical inferences to be formed, sampling bias must be minimised.

Using linear approximation, the value of f(3.01) can be approximated by evaluating the tangent line to the function f(x) = x^2 at x = 3 and using it to estimate the value at x = 3.01.

Linear approximation is a method used to estimate the value of a function near a specific point by considering the tangent line at that point. The tangent line is a linear function that approximates the behavior of the original function in the vicinity of the point.

To approximate f(3.01) using linear approximation, we start by finding the slope of the tangent line at x = 3. This can be done by taking the derivative of f(x) = x^2, which is f'(x) = 2x. Evaluating f'(3) gives us the slope of the tangent line at x = 3.

Next, we use the point-slope form of a linear equation to write the equation of the tangent line. Plugging in the values x = 3, y = f(3) = 9, and the slope from f'(3), we can determine the equation of the tangent line.

Finally, we evaluate the tangent line at x = 3.01 to approximate the value of f(3.01). This can be done by substituting x = 3.01 into the equation of the tangent line and solving for y. The resulting value is an approximation of f(3.01) using linear approximation.

The man has 23 dimes and 15 quarters.

Let's assume the number of dimes is represented by 'd' and the number of quarters is represented by 'q'.

According to the information given in the problem, we have two equations:

Equation 1: d + q = 38 (since the total number of dimes and quarters is 38)

Equation 2: 10d + 25q = 615 (since the total value of dimes and quarters is 615 cents)

We can solve this system of equations to find the values of 'd' and 'q'.

Let's multiply Equation 1 by 10 to eliminate 'd':

10d + 10q = 380

Now, subtract this equation from Equation 2:

10d + 25q - (10d + 10q) = 615 - 380

15q = 235

q = 235/15

q ≈ 15.67

Since we can't have a fractional number of quarters, we'll round down to the nearest whole number:

q ≈ 15

Now, substitute the value of 'q' back into Equation 1 to find 'd':

d + 15 = 38

d = 38 - 15

d = 23

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.
