The evaluation of f(x, y) on the curve c is f(x, y) = y * sin(z) = sin(t) * sin(t) = sin^2(t).

We are given the function f(x, y) = y * sin(z) and the curve c parameterized as x = cos(t), y = sin(t), and z = t. To evaluate f(x, y) on the curve c, we substitute the values of x, y, and z from the parameterization into the function. Therefore, f(x, y) = y * sin(z) becomes f(x, y) = sin(t) * sin(t), which simplifies to f(x, y) = sin^2(t).

The evaluation gives us the expression sin^2(t), which represents the value of f(x, y) on the curve c.

The given equation y = -0.114x + 1.658 represents a linear model that relates the depth (x) of a major river to its velocity (y).

The slope of the equation, -0.114, indicates the rate at which the velocity of the river changes with respect to the depth. The intercept, 1.658, represents the velocity of the river when the depth is zero.

The correlation coefficient, 0.964, indicates the strength and direction of the relationship between the depth and velocity of the river. It signifies a strong positive correlation, meaning that as the depth increases, the velocity of the river tends to decrease. The closer the correlation coefficient is to 1, the stronger the linear relationship between the variables. In this case, the correlation coefficient of 0.964 suggests a significant relationship between the depth and velocity of the river, indicating that the linear model is a good fit for the data.

Part A: The slope of the equation, -0.114, represents the rate of change in the velocity of the river with respect to the depth. For every increase of 1 foot in depth, the velocity decreases by 0.114 feet per second. This implies that as the depth of the river increases, the velocity tends to decrease at a certain rate.

The intercept of the equation, 1.658, represents the velocity of the river when the depth is zero. In this context, it means that when the river has no depth (such as at the surface or a shallow area), the velocity is 1.658 feet per second.

Part B: The correlation coefficient, 0.964, indicates the strength and direction of the relationship between the depth and velocity of the river. A correlation coefficient of 0.964 suggests a strong positive correlation, meaning that as the depth of the river increases, the velocity tends to decrease. The closer the correlation coefficient is to 1, the stronger the linear relationship between the variables. In this case, the high correlation coefficient of 0.964 suggests that the depth and velocity of the river are strongly related, and the linear model provides a good approximation for the data collected.

Answer:

\( k = 26 \)   or   \( k = -\dfrac{22}{5} \)

Step-by-step explanation:

|3k - 2| = 2|k + 12|

\( \dfrac{|3k - 2|}{|k + 12|} = 2 \)

\( |\dfrac{3k - 2}{k + 12}| = 2 \)

\( 3k - 2 = 2(k + 12) \)   or   \( 3k - 2 = -2(k + 12) \)

\( 3k - 2 = 2k + 24 \)   or   \( 3k - 2 = -2k - 24 \)

\( k = 26 \)   or   \( 5k = -22 \)

(a) Matched pairs t-test

(b) The test statistic is 5.4508.

(c) The critical value is 3.2502.

(d) Answer B. yes is correct.

(a) The test method to be used to consider (Test A - Test B) with a 0.01 significance level to test the claim that people do better on the second test than they do on the first is Matched Pairs.

(b) The test statistic is calculated using the formula

t = d/ (s/ √n). Here, d is the difference between the two sets of data, s is the standard deviation of the differences and n is the number of matched pairs in the sample.

Since the sample size is small and the population variance is unknown, the t-distribution should be used. If the value of t lies in the critical region, then the null hypothesis is rejected. Using the data given, we have,

Mean of differences = 5

The standard deviation of differences = 4.5826

n = 10

t = 5 / (4.5826 / √10)

t = 5.4508

(c) The critical value is obtained from the t-table, using a significance level of 0.01 and 9 degrees of freedom. The critical value is 3.2502.

(d) Since the calculated t-value (5.4508) is greater than the critical value (3.2502), we reject the null hypothesis. Therefore, there is sufficient evidence to support the claim that people do better on the second test than they do on the first. The answer is B. Yes.

The measure of center should be used is Mean, because Sunny Town is symmetric.

When comparing the data to determine which location typically has the cooler temperature, the measure of center that should be used is the mean. The mean (average) is a suitable measure of center for symmetric distributions, which is the case in Sunny Town. When a distribution is symmetric, the mean provides an accurate representation of the center of the data.

On the other hand, the distribution in Beach Town is skewed.

A skewed distribution means that the data is not symmetric and has a long tail on one side. In such cases, the median is a more appropriate measure of center. The median represents the middle value of a dataset and is less affected by extreme values or outliers, making it a better choice for skewed distributions.

Answer:

Instructions are below.

Step-by-step explanation:

Giving the following information:

Fixed costs= 4,000 + 10,000= $14,000

Unitary variable cost= $5.5

Selling price= $7.2

To calculate the number of units to be sold to break-even, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 14,000 / (7.2 - 5.5)

Break-even point in units= 8,235 units

In dollars:

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 14,000 / (1.7/7.2)

Break-even point (dollars)= $59,294

Now, imagine the company requires a profit of $50,000:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= 64,000/1.7

Break-even point in units= 37,647 units

Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio

Break-even point (dollars)= 64,000 / (1.7/7.2)

Break-even point (dollars)= $271,059

The number of bricks needed to cover the patio is approximately 1811 bricks.

To find the number of bricks needed for the patio in the English system, we follow these steps:

Step 1: Find the total width and length of the patio in inches.

Convert the width and length in meters to inches:

Width: 5 m = 5 x 39.37 = 196.85 in.

Length: 6 m = 6 x 39.37 = 236.22 in.

Add these values to the portion of the width and length of the patio expressed in inches to find totals:

Total width: 196.85 in. + 16 in. = 212.85 in.

Total length: 236.22 in. + 19 in. = 255.22 in.

Step 2: Find the area of each brick in square inches.

Multiply its width by its length:

Brick area: 3.75 in. x 8 in. = 30 in².

Step 3: Find the number of bricks needed by dividing the patio area by the brick area (round up to the nearest whole brick):

Patio area: 212.85 in. x 255.22 in. = 54,318.837 in².

Number of bricks needed: 54,318.837 in² / 30 in² ≈ 1810.63 bricks.
