Step-by-step explanation:

to solve this question, we need to use the graph on the left to find the proportions of students who prefer each pasta dish, and then multiply those proportions by 400 to get the estimated number of students in the whole school who prefer each pasta dish. Then we need to plot those numbers on a bar graph with the pasta dishes on the horizontal axis and the number of students on the vertical axis. The graph below shows one possible way to create the bar graph:

We can see that the vertical axis is numbered from 0 to 120 in increments of 20. The bars show the estimated number of students who prefer each pasta dish, based on the sample of 16 students. For example, since 4 out of 16 students prefer spaghetti, we can estimate that 4/16 x 400 = 100 students in the whole school prefer spaghetti. Similarly, since 3 out of 16 students prefer lasagna, we can estimate that 3/16 x 400 = 75 students in the whole school prefer lasagna. We can repeat this process for the other pasta dishes and plot them on the graph.

The length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.

Let's start by using the formula for the area of a rectangle, which is:

Area = length x width

We are given that the width of the platform is (x+4) meters, so we can write:

Area = length x (x+4)

We are also given that the area of the platform is 3x^2+10x−8, so we can set these two expressions equal to each other and solve for the length:

3x^2+10x−8 = length x (x+4)

Expanding the right side, we get:

3x^2+10x−8 = length x^2 + 4length

Subtracting 4length from both sides, we get:

3x^2+10x−8−4length = length x^2

Rearranging, we get a quadratic equation:

length x^2 + 4length − 3x^2 − 10x + 8 = 0

To solve for length, we can use the quadratic formula:

length = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = 4, and c = -3x^2 - 10x + 8. Plugging in these values, we get:

length = (-4 ± sqrt(4^2 - 4(1)(-3x^2 - 10x + 8))) / 2(1)

Simplifying under the square root:

length = (-4 ± sqrt(16 + 12x^2 + 40x - 32)) / 2

length = (-4 ± sqrt(12x^2 + 40x)) / 2

length = (-4 ± 2sqrt(3x^2 + 10x)) / 2

length = -2 ± sqrt(3x^2 + 10x)

Since the length must be positive, we take the positive square root:

length = -2 + sqrt(3x^2 + 10x)

Therefore, the length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.

Answer:

$4139.93

Step-by-step explanation:

Formula for amount accrued at compound interest annually is given by

A = P( 1+ r)ⁿ

where
P = principal
r = interest rate expressed as a decimal
n = number of years

Given P = 3900, r = 1/100 = 0.01, n = 6 we get

A = 3900(1 + 0.01)⁶ = 3900(1.01)⁶ = 4139.93

So the amount accrued after 6 years = $4139.93

The rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. The correct option is C.

The function C(x) = 25x² - 98x represents the cost of printing magazines per day at a printing press. To find the rate of change of cost when 17 magazines are printed per day, we need to calculate the derivative of the function with respect to x (the number of magazines printed), which represents the rate of change at a given point.

The derivative of C(x) with respect to x can be found using the power rule for differentiation. For a function of the form f(x) = [tex]ax^n[/tex], its derivative is f'(x) = [tex]n*ax^{(n-1)[/tex].

Applying the power rule to our function, we get:
C'(x) = 2(25x) - 98 = 50x - 98.

Now, we need to evaluate C'(x) when x = 17 (the number of magazines printed per day):
C'(17) = 50(17) - 98 = 850 - 98 = 752.

Therefore, the rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. So, the correct answer is: C. 752$/print.

The statements are classified as follows:

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations, which is also called the cardinality of the data-set.

8 is a low outlier, hence it is a value lower than the mean, meaning that the mean increases if we remove the observation of 8.

The range of a data-set is calculated as the difference between the highest value and the lowest value in the data-set, thus if we remove the low value of 8, the next low value is of 47, meaning that the range decreases.

The ordered data-set is given as follows:

8, 47, 48, 50, 51, 51.

The data-set has an even cardinality of 6, hence the median is calculated as the mean of the two middle elements as follows:

Median = (48 + 50)/2

Median = 49.

Removing 8, the data-set is given as follows:

The Fourier series Using the complex form of f(x) is

f(x) = 1/2 + ∑[n=1, ∞] [2*(-1)^(n+k)/(nπ)]*sin(nπx), 2k-0.25 < x < 2k+0.25

where k is an integer.

To find the Fourier series of the function f(x) over the interval [-1, 1], we first note that f(x) is periodic with period T = 0.5. We can then write f(x) as a Fourier series of the form

f(x) = a0/2 + ∑[n=1, ∞] (ancos(nπx) + bnsin(nπx))

where

a0 = (1/T) ∫[0,T] f(x) dx

an = (2/T) ∫[0,T] f(x)*cos(nπx) dx

bn = (2/T) ∫[0,T] f(x)*sin(nπx) dx

Since f(x) = 0 for x < -0.25 and x > 0.25, we only need to consider the interval [-0.25, 0.25]. We can break this interval into subintervals of length 0.5 centered at integer values k

[-0.25, 0.25] = [-0.25, 0.25] ∩ [1.5, 2.5] ∪ [-0.25, 0.25] ∩ [0.5, 1.5] ∪ ... ∪ [-0.25, 0.25] ∩ [-1.5, -0.5]

For each subinterval, the Fourier coefficients can be calculated as follows

a0 = (1/0.5) ∫[-0.25, 0.25] f(x) dx = 1/2

an = (2/0.5) ∫[-0.25, 0.25] f(x)*cos(nπx) dx = 0

bn = (2/0.5) ∫[-0.25, 0.25] f(x)sin(nπx) dx = 2(-1)^k/(nπ)

Therefore, the Fourier series of f(x) is

f(x) = 1/2 + ∑[n=1, ∞] [2*(-1)^(n+k)/(nπ)]*sin(nπx), 2k-0.25 < x < 2k+0.25

a) The height of the tide at low tide is 3.7 feet.

b) The period of the function is 12 hours and it means that the tide goes through a full cycle of high tide.

c) The first time the tide reaches a height of 3 feet is therefore either 23.82 hours or 40.18 hours after high tide.

a. To find the height of the tide at low tide, we need to find the minimum value of the function f(x).

Since cos(π/6 x) has a maximum value of 1 and a minimum value of -1, the minimum value of the entire function occurs when cos(π/6 x) = -1.

This happens when π/6 x = π + 2nπ, where n is any integer.

Solving for x, we get x = 12 + 12n.

Substituting this value of x into the function, we get f(x) = 0 + 3.7 = 3.7 feet.

b. The period of the function is the time it takes for the function to complete one full cycle. Since the period of cos(π/6 x) is 2π/π/6 = 12 hours, the period of the entire function f(x) is also 12 hours. This means that the tide goes through a full cycle of high tide and low tide every 12 hours at this location.

c. To find the first time the tide reaches a height of 3 feet, we need to solve the equation 3 = 3.5 cos (π/6 x) + 3.7 for x.

Subtracting 3.7 from both sides and dividing by 3.5, we get cos(π/6 x) = -0.086.

Taking the inverse cosine of both sides, we get π/6 x = 1.67 + 2nπ or π/6 x = -1.67 + 2nπ, where n is any integer.

Solving for x, we get x = 40.18 + 24n or x = 23.82 + 24n.

The first time the tide reaches a height of 3 feet is therefore either 23.82 hours or 40.18 hours after high tide.

The estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

To estimate the quantity of the substance at t = 1.9 using linear approximation, we can use the formula:

ΔR ≈ dR/dt * Δt

Given the point R(2) = 35 and the differential equation dR/dt = -1/5(R – 20), we can first find the value of dR/dt at t = 2.

dR/dt(2) = -1/5(R(2) – 20) = -1/5(35 – 20) = -1/5(15) = -3

Now, we can calculate Δt, which is the difference between the given t-value (2) and the desired t-value (1.9):

Δt = 1.9 - 2 = -0.1

Next, we can calculate ΔR using the linear approximation formula:

ΔR ≈ dR/dt * Δt ≈ -3 * (-0.1) = 0.3

Finally, we can estimate the quantity of the substance at t = 1.9 by adding ΔR to the given value of R(2):

R(1.9) ≈ R(2) + ΔR ≈ 35 + 0.3 = 35.3

Therefore, the estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

Answer: To have infinitely many solutions, the equation must be true for all values of x. In other words, the left side and right side of the equation must be equivalent, meaning that the coefficients of x on both sides of the equation must be equal, and the constant terms on both sides must be equal.

We can simplify the given equation as follows:

5(x + 3) = a(x + 4) + 3x + b

5x + 15 = ax + 4a + 3x + b

Simplifying further, we get:

8x + 4a + b = 5x + 15

Rearranging terms, we get:

3x + 4a + b - 15 = 0

For this equation to have infinitely many solutions, the coefficients of x on both sides must be equal to zero, meaning that:

3 = 0

This is not possible, so the equation cannot have infinitely many solutions for any values of a and b.

Therefore, there are no values of a and b for which the given equation will have infinitely many solutions.

Neave should mark 12 sections as "win" on the prize wheel to achieve the expected number of winners of 60 out of 200 students.

To determine how many sections should be marked "win" on Neave's prize wheel, we need to consider the expected number of winners and the total number of sections on the wheel.

Neave wants the expected number of winners to be 60 out of 200 students. This means that the probability of winning should be 60/200 = 0.3 or 30%.

If the wheel is split into 40 equally sized sections, we can assume that each section has an equal probability of being selected by a student. Therefore, to have a 30% chance of winning, we need to mark a proportionate number of sections as "win".

To calculate the number of sections to mark as "win", we multiply the total number of sections by the desired probability of winning:

40 sections * 0.3 = 12 sections.

It's important to note that the concept of expected value assumes an idealized scenario with perfect randomness. In reality, the actual number of winners may vary due to random chance and individual spin outcomes.

To find the surface area of a prism, you need to add up the area of all of its faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Make sure that all of these measurements are in the same units, such as inches or centimeters.

Once you have calculated each of the areas, add them together to get the total surface area of the prism. Make sure to include the units in your answer, which will be in square inches or in2.

You will need to know its dimensions and follow these steps:

1. Determine the shape and dimensions of the base and top faces.
2. Calculate the area of the base and top faces.
3. Determine the shape and dimensions of the lateral faces.
4. Calculate the area of the lateral faces.
5. Add the areas of all the faces to find the total surface area.

Without specific dimensions, I cannot provide a numerical answer. However, once you have the dimensions, follow the steps above to find the surface area of the prism in square inches (in²).
