Answer:

18 rotations.

Step-by-step explanation:

As there are 360 degrees in a circle, by proportion, the time for 1 rotation

= (360/107) * 1

= 3.364 minutes.

So the number of rotations in 1 hour (60 minutes)

=  60 / 3.364

= 17.83

Number of rotations does the pulley make in an hour is 18.

Here,

A pulley rotates through 107° in one minute.

What is rotations?

The action or process of rotating on or as if on an axis or center.

Now,

As there are 360° in a circle, by proportion;

Time for one rotation = (360/107) x 1

                                = 3.364 minutes

Hence, number of rotations in 1 hour

= 60 / 3.364

= 17.83

So, Number of rotations does the pulley make in an hour is 18.

The general solution of the given system of differential equations is:

y = -37 × (1/2)x² + 5x + C, where C is the constant of integration.

The general solution of a system of derivative equations refers to a set of equations or formulas that represent all possible solutions of the given system. It includes an arbitrary constant or constants, which can take different values to yield different specific solutions.

The form of the general solution depends on the nature of the equations and the techniques used to solve them.

Here we have

dx/dt = 7x + y and dy/dt = -2x + 5y

To find the general solution of the given system of differential equations:

=> dx/dt = 7x + y  __ (1)

=> dy/dt = -2x + 5y  __(2)

Solve it using the method of simultaneous equations.

Solve Equation (1) for y:

y = dx/dt - 7x

Substitute the value of y in Equation (2):

dy/dt = -2x + 5(dx/dt - 7x)

Simplify the equation:

dy/dt = 5dx/dt - 2x - 35x

dy/dt = 5dx/dt - 37x

Rearrange the equation:

dy/dt - 5dx/dt = -37x

Multiply through by dt:

dy - 5dx = -37x dt

Integrate both sides of the equation:

∫(dy - 5dx) = ∫(-37x) dt

Integrate each term:

y - 5x = -37 * (1/2)x² + C

Simplify the equation:

y = -37 × (1/2)x² + 5x + C

Therefore,

The general solution of the given system of differential equations is:

Remark

If the entire circle was shaded the radius sweeping out the circle would go through 360 degrees.

So the way to solve this problem is to multiply the entire area of the circle by (81/360)

Area of the sector = (81/360) * pi * r^2

pi = 3.14

r =8.91 cm

Area of the sector = (81/360) * 3.14 * 8.91^2

The quadratic function that best models the given data is option d: y = -x^2 + 20x + 60 because it is a quadratic function and its graph is a downward-facing parabola.

To determine which function best models the given data, we will analyze the options and evaluate their fit based on the information provided.

\(Option a: y = -x^2 + 20x + 40Option b: y = -2x^2 + 20x + 60Option c: y = x^2 + 20x + 60Option d: y = -x^2 + 20x + 60\)

We will compare the options based on their general form and characteristics to see which one aligns best with the given data.

1. Quadratic form: All the options are quadratic functions in standard form, y = ax^2 + bx + c, which is suitable for modeling a parabolic relationship.

2. Coefficients: Let's compare the coefficients a, b, and c for each option:

  Option a: a = -1, b = 20, c = 40

  Option b: a = -2, b = 20, c = 60

  Option c: a = 1, b = 20, c = 60

  Option d: a = -1, b = 20, c = 60

  Among these options, we notice that options a, b, and d share the same coefficient values for a and b, while option c has a different value for a. Since the coefficients a and b are the same for options a, b, and d, we will focus on those.

3. Vertex and concavity: The vertex of a quadratic function in standard form is given by (-b/2a, f(-b/2a)), where f(x) represents the function. The concavity of the parabola can be determined by the sign of the coefficient a.

  For options a, b, and d, the vertex is (10, f(10)) since b = 20 and a = -1 for these options.

  Option a: Vertex (10, f(10))

  Option b: Vertex (10, f(10))

  Option d: Vertex (10, f(10))

  Since the coefficient a is negative in all three options, the parabolas will have a downward-facing concavity.

4. Evaluation: Based on the above analysis, we can conclude that options a, b, and d have similar characteristics and share the same vertex at (10, f(10)). However, option c differs from the others in terms of its coefficient a and does not match the given data as closely.

Therefore, the quadratic function that best models the given data is option d: y = -x^2 + 20x + 60 because it is a quadratic function and its graph is a downward-facing parabola.

The best function that models the given data is y = -x^2 + 20x + 60.

The best function that models the given data of the number of visitors in the park requiring first aid during the heat wave is option d. \(y = -x^2 + 20x + 60\).
To determine the best function, we need to consider the characteristics of the scatter plot. The function that models the data should exhibit a downward-opening parabolic shape because the number of visitors requiring first aid decreases as the number of visitors increases.

Looking at the options, we can see that option d is the only one that represents a downward-opening parabola. The negative coefficient of \(x^2\)(-1) ensures that the parabola opens downwards.
The coefficient of x in option d (+20) indicates that the parabola is shifted 20 units to the right. This makes sense because as the number of visitors increases, the number requiring first aid also increases, indicating that the peak of the parabola occurs at a higher number of visitors.
The constant term (+60) represents the y-intercept, which is the value of y when x is 0. In this case, it represents the initial number of visitors requiring first aid.

The correlation analysis indicates a moderate positive relationship between Column X and Column Y.

To perform correlation analysis, we can use the Pearson correlation coefficient (r) to measure the linear relationship between two variables, in this case, Column X and Column Y. The value of r ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.

Here are the steps to calculate the correlation coefficient:

Calculate the mean (average) of Column X and Column Y.

Mean(X) = (10+6+39+24+35+12+33+32+23+10+16+16+35+28+5+22+12+44+15+40+46+35+28+9+9+8+35+15+34+16+19+17+21) / 32 = 24.4375

Mean(Y) = (37+10+18+12+11+34+26+9+42+24+40+1+39+24+42+7+17+17+27+47+35+14+38+18+17+22+12+30+18+43+24+45+24) / 32 = 24.8125

Calculate the deviation of each value from the mean for both Column X and Column Y.

Deviation(X) = (10-24.4375, 6-24.4375, 39-24.4375, 24-24.4375, ...)

Deviation(Y) = (37-24.8125, 10-24.8125, 18-24.8125, 12-24.8125, ...)

Calculate the product of the deviations for each pair of values.

Product(X, Y) = (Deviation(X1) * Deviation(Y1), Deviation(X2) * Deviation(Y2), ...)

Calculate the sum of the product of deviations.

Sum(Product(X, Y)) = (Product(X1, Y1) + Product(X2, Y2) + ...)

Calculate the standard deviation of Column X and Column Y.

StandardDeviation(X) = √[(Σ(Deviation(X))^2) / (n-1)]

StandardDeviation(Y) = √[(Σ(Deviation(Y))^2) / (n-1)]

Calculate the correlation coefficient (r).

r = (Sum(Product(X, Y))) / [(StandardDeviation(X) * StandardDeviation(Y))]

By performing these calculations, we find that the correlation coefficient (r) is approximately 0.413. Since the value is positive and between 0 and 1, we can conclude that there is a moderate positive relationship between Column X and Column Y.

Using synthetic division, we can divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1. Performing the synthetic division, we obtain a quotient of x² + 6x - 6 and a remainder of 8.

To divide the polynomial x³ + 7x² - 12x + 14 by the divisor 1 using synthetic division, we set up the synthetic division table as follows:

1  |   1   7  -12   14

We begin by bringing down the coefficient of the first term, which is 1, and place it on the line below the division bar. Then we multiply the divisor, 1, by the value we brought down and write the result under the next coefficient. Adding the values in the second row, we obtain the new value. We continue this process for each term until we reach the last term.

1  |   1   7  -12   14

 1   8  -4     10

The values in the last row represent the coefficients of the quotient polynomial. Therefore, the quotient is x² + 6x - 6. The remainder, which is the last value in the last row, is 10. Since the divisor is 1, the remainder does not affect the quotient. Hence, the result of the division is x² + 6x - 6 with a remainder of 10.

The national average ACT score is greater than the Washington DC average

To conduct a hypothesis test, we start by stating the null hypothesis (H₀) and the alternative hypothesis (H₁). The null hypothesis is usually the claim or statement that we want to test, while the alternative hypothesis is the opposite of the null hypothesis. In this case, the null hypothesis is that the national average ACT score is not greater than the Washington DC average, while the alternative hypothesis is that the national average ACT score is greater than the Washington DC average.

Hypotheses: H₀ : µn <= µDC, H₁ : µn > µDC

Next, we need to determine the critical value(s) for the test. A significance level of 0.01 corresponds to a critical value of 2.33 for a one-tailed test, which is what we have in this case.

Critical value(s): CV = 2.33

To compute the test statistic. We will use a z-test since the population standard deviation is known.

Test statistic: z = (µn - µDC - 0) / (σ / √(n))

where µn = 21.4, µDC = 21.1, σ = 3, and n = 500.

Substituting the values, we get:

z = (21.4 - 21.1 - 0) / (3 / √(500))

z = 1.94

In this case, the test statistic is 1.94, which is greater than the critical value of 2.33. Therefore, we reject the null hypothesis and conclude that there is enough evidence to support the claim that the national average ACT score is greater than the Washington DC average

To find the margin of error (E) for the college students' annual earnings with a 99% confidence level, given a sample size of 71, a sample mean (x) of $3660, and a population standard deviation (σ) of $879, we can use the formula for margin of error. Therefore, the margin of error (E) for the college students' annual earnings with a 99% confidence level is approximately $252.43.

The margin of error (E) represents the maximum likely difference between the sample mean and the true population mean within a given confidence level. To calculate the margin of error, we use the following formula:

E = Z * (σ / √n)

Where:

Z is the z-score corresponding to the desired confidence level (in this case, for a 99% confidence level, Z is the z-score that leaves a 0.5% tail on each side, which is approximately 2.576).

σ is the population standard deviation.

n is the sample size.

Plugging in the given values, we have:

E = 2.576 * ($879 / √71) ≈ $252.43

Therefore, the margin of error (E) for the college students' annual earnings with a 99% confidence level is approximately $252.43. This means that we can estimate, with 99% confidence, that the true population mean annual earnings for college students lies within $252.43 of the sample mean of $3660.

a. To compute the mean, we sum up all the values in the sample and divide by the number of values:

Mean = (10 + 6 + 4 + 8 + 2) / 5 = 6

To compute the median, we arrange the values in ascending order and find the middle value. In this case, the values are already in ascending order, so the median is the middle value:

Median = 6

To compute the mode, we identify the value(s) that appear(s) most frequently. In this case, there is no value that appears more than once, so there is no mode.

b. To compute the range, we find the difference between the maximum and minimum values:

Range = 10 - 2 = 8

To compute the variance, we calculate the average squared deviation from the mean:

Variance = [(10 - 6)^2 + (6 - 6)^2 + (4 - 6)^2 + (8 - 6)^2 + (2 - 6)^2] / 5 = 8

To compute the standard deviation, we take the square root of the variance:

Standard Deviation = sqrt(8) = 2.83

The coefficient of variation is the ratio of the standard deviation to the mean, expressed as a percentage:

Coefficient of Variation = (2.83 / 6) * 100 = 47.17%

c. To compute the Z-scores, we subtract the mean from each value and divide by the standard deviation:

Z1 = (10 - 6) / 2.83 ≈ 1.41

Z2 = (6 - 6) / 2.83 ≈ 0

Z3 = (4 - 6) / 2.83 ≈ -0.71
