To find the partial derivatives of the function z = 4y^3 - 7yx + 5x^2, we can use the formal definition of partial derivatives. First, we find the difference quotient with respect to y and evaluate it at a given point. Second, we find the difference quotient with respect to x and evaluate it at the same point.

The given function is z = 4y^3 - 7yx + 5x^2. To find the partial derivative ∂z/∂y, we use the formal definition of partial derivatives. The difference quotient is given by [f(x, y + h) - f(x, y)]/h, where h is a small value approaching zero. Substituting the function into the difference quotient, we have [(4(y + h)^3 - 7x(y + h) + 5x^2) - (4y^3 - 7xy + 5x^2)]/h. Simplifying this expression, we expand (y + h)^3 to y^3 + 3y^2h + 3yh^2 + h^3 and distribute the terms. After canceling out common terms and factoring out h, we can take the limit of h as it approaches zero to find the partial derivative ∂z/∂y.

Similarly, to find the partial derivative ∂z/∂x, we use the same difference quotient formula. We substitute the function into the difference quotient [(4y^3 - 7x(y + h) + 5(x + h)^2) - (4y^3 - 7xy + 5x^2)]/h and simplify it. Expanding (x + h)^2 to x^2 + 2xh + h^2, distributing the terms, canceling out common terms, and factoring out h, we can evaluate the limit as h approaches zero to find the partial derivative ∂z/∂x.

By following these steps, we can find the partial derivatives ∂z/∂y and ∂z/∂x of the given function using the formal definition of partial derivatives.

(a) The probability of ending up with two hits is approximately 0.1406.

(b) The probability of ending up with no hits is approximately 0.4219.

(c) The probability of ending up with exactly three hits is approximately 0.0156.

(d) The probability of ending up with at most one hit is approximately 0.8438.

To solve the given problem, we need to use the concept of binomial probability since each at-bat is independent and has the same probability of a hit. We'll use the batting average of 0.250 to calculate the probabilities.

The probability of a hit is given by the batting average, which is 0.250.

(a) To find the probability that she ends up with two hits:

Using the binomial probability formula, the probability of getting exactly two hits in three at-bats can be calculated as follows:

P(X = 2) = (3 choose 2) * \((0.250)^2 * (1 - 0.250)^(^3^ -^ 2^)\)

Calculating the values:

P(X = 2) = (3 choose 2) * \((0.250)^2 * (0.750)^1\)

P(X = 2) = 3 * 0.0625 * 0.750

P(X = 2) ≈ 0.1406

Therefore, the probability that she ends up with two hits is approximately 0.1406.

(b) To find the probability that she ends up with no hits:

Using the same binomial probability formula, the probability of getting no hits in three at-bats can be calculated as follows:

P(X = 0) = (3 choose 0) *\((0.250)^0 * (1 - 0.250)^(^3^ -^ 0^)\)

Calculating the values:

P(X = 0) = (3 choose 0) *\((0.250)^0 * (0.750)^3\)

P(X = 0) = 1 * 1 * 0.4219

P(X = 0) ≈ 0.4219

Therefore, the probability that she ends up with no hits is approximately 0.4219.

(c) To find the probability that she ends up with exactly three hits:

Using the same binomial probability formula, the probability of getting three hits in three at-bats can be calculated as follows:

P(X = 3) = (3 choose 3) \(* (0.250)^3 * (1 - 0.250)^(^3^ -^ 3^)\)

Calculating the values:

P(X = 3) = (3 choose 3) *\((0.250)^3 * (0.750)^0\)

P(X = 3) = 1 * 0.0156 * 1

P(X = 3) ≈ 0.0156

Therefore, the probability that she ends up with exactly three hits is approximately 0.0156.

(d) To find the probability that she ends up with at most one hit:

We can find this probability by calculating the sum of the probabilities of getting 0 hits and 1 hit.

P(X ≤ 1) = P(X = 0) + P(X = 1)

Substituting the calculated values:

P(X ≤ 1) ≈ 0.4219 + P(X = 1)

To calculate P(X = 1), we can use the binomial probability formula as before:

P(X = 1) = (3 choose 1) * \((0.250)^1 * (0.750)^(^3^-^1^)\)

Calculating the values:

P(X = 1) = (3 choose 1) * \((0.250)^1 * (0.750)^2\)

P(X = 1) = 3 * 0.250 * 0.5625

P(X = 1) ≈ 0.4219

Substituting back into the equation:

P(X ≤ 1)

≈ 0.4219 + 0.4219

P(X ≤ 1) ≈ 0.8438

Therefore, the probability that she ends up with at most one hit is approximately 0.8438.

Step-by-step explanation:

I can explain the process of finding the test statistic for testing the equality of variances for three brands. Please note that the exact calculation depends on the specific statistical test you are using.

To test the equality of variances among three brands, you can use the Bartlett's test or Levene's test. Here, I will explain the steps for performing Levene's test:

Step 1: Set up hypotheses

- Null hypothesis (H0): The variances of the three brands are equal.

- Alternative hypothesis (HA): The variances of the three brands are not equal.

Step 2: Calculate the test statistic

Levene's test statistic is based on the absolute deviations of each observation from the group mean. The test statistic is given by:

\[ W = \frac{(N-k)}{(k-1)} \times \frac{\sum_{i=1}^{k}N_i(\bar{Z_i} - \bar{Z})^2}{\sum_{i=1}^{k}\sum_{j=1}^{N_i}(Z_{ij} - \bar{Z_i})^2}\]

where:

- N is the total number of observations.

- k is the number of groups (in this case, three brands).

- Ni is the number of observations in the i-th group.

- Zi is the absolute deviation of each observation in the i-th group from the group mean.

- Z is the overall mean of all observations.

Step 3: Conclusion

Compare the calculated test statistic with the critical value from the appropriate distribution (e.g., F-distribution). If the calculated test statistic is greater than the critical value, you would reject the null hypothesis and conclude that the variances are not equal. Conversely, if the calculated test statistic is less than the critical value, you would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest a difference in variances among the three brands.

Remember to round your answer to three decimal places as requested.

It's important to note that without specific data, I can't provide an actual calculation or conclusion. The above explanation provides a general overview of the steps involved in testing the equality of variances for three brands.

The area of a square can be found by using the following expression:

where "A" is the area and "l" is the length of each side of the square. The square on this problem has an area of 9 cm², so we can find the sides by replacing A for 9 on the expression above.

To solve it we need to take the square root on both sides of the equation.

Each side of the square has a length of 3 cm, so the sides are 3 cm x 3 cm.

Answer:

\(y=-\frac{9}{8} x+7\)

Step-by-step explanation:

The slope is found by doing the equation \(\frac{rise}{run}\). When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal \(-\frac{9}{8}\).

The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.

The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!

If Mo and Beth split £48 in the ratio 3.5, Beth gets £10.67.

Let's call the amount that Beth gets "x". Then, the amount that Mo gets is 3.5x.

We know that the total amount they split is £48, so we can set up the following equation:

x + 3.5x = £48

Next, we'll simplify the left side of the equation by combining like terms:

4.5x = £48

Finally, we'll solve for x by dividing both sides of the equation by 4.5:

x = £48 / 4.5 = £10.67

So Beth gets £10.67.

Connect the points where the first arc crosses the triangle's base and the second arc intersects the base of the triangle with the straightedge to create the triangle's third side, BC.

Generally, To accurately construct triangle ABC, you will need a straightedge (such as a ruler) and a protractor. Here are the steps to follow:

Use the straightedge to draw a straight line segment of length 8 cm, which will represent side AB. This line segment will be the base of the triangle.

Place the point of the protractor at one end of the line segment and draw an arc that intersects the other end of the line segment.

Measure the angle formed by the line segment and the arc using the protractor. The measure of this angle should be 70 degrees.

Without changing the position of the protractor, draw another arc that intersects the first arc and the base of the triangle.

Use the straightedge to connect the point where the second arc intersects the base of the triangle to the point where the first arc intersects the base of the triangle. This will form the third side of the triangle, AC.

Finally, use the straightedge to draw the third side of the triangle, BC, by connecting the point where the first arc intersects the base of the triangle to the point where the second arc intersects the base of the triangle.

To determine if a data point is considered an outlier for a data set, we need to calculate the interquartile range (IQR) and use it to define the outlier boundaries. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). The correct option is (B).

We have that Q1 = 9 and Q3 = 17, we can calculate the IQR as follows:

IQR = Q3 - Q1 = 17 - 9 = 8

To identify outliers, we can use the following rule:

- Any data point that is less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR is considered an outlier.

Using this rule, we can evaluate each data point:

A. 27: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

B. 17: This data point is not an outlier because it is equal to the third quartile (Q3).

C. 3: This data point is less than Q1 - 1.5 * IQR = 9 - 1.5 * 8 = -3. It is considered an outlier.

D. 41: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

Therefore, the outliers in the data set are A (27) and D (41).

As for when to use the mean, it is generally recommended to use the mean as a measure of central tendency when the data is symmetric and does not have extreme values.

Therefore, the correct option would be B. When the data is symmetric.

The 14.9% increase in Sylvia's lead lathe tech's hourly wage of $18.50 results in a $2.75 per hour increase. Assuming the lead lathe tech works 2,080 hours per year, the additional cost to Sylvia's annual wages budget would be approximately $5,720, excluding benefits or taxes.

First, we need to find the percentage increase in the lead lathe tech's hourly wage. The increase requested is $2.75, which is 14.9% of the current wage rate ($18.50). To calculate the percentage increase, we divide the increase by the current wage rate and multiply by 100: ($2.75 / $18.50) * 100 ≈ 14.9%.

To determine the additional cost to Sylvia's annual wages budget, we need to know the total number of hours worked by the lead lathe tech in a year. Let's assume the lead lathe tech works 40 hours per week and there are 52 weeks in a year, resulting in a total of 2,080 hours.

To calculate the annual cost of the wage increase, we multiply the hourly increase ($2.75) by the total number of hours worked (2,080): $2.75 * 2,080 ≈ $5,720.

The Taylor polynomials of orders 0, 1, 2, and 3 generated by f(x) = 7ln(x) at a=1 are:

\(P_0(x) = 0\\P_1(x) = 7x - 7\\P_2(x) = 7x - 7 - 7(x-1)^2/2\\P_3(x) = 7x - 7 - 7(x-1)^2/2 + 14(x-1)^3/3\)

The Taylor polynomials of orders 0, 1, 2, and 3 generated by f(x) = 3/x at x=4 are:

\(P_0(x) = 3/4\\P_1(x) = 3/4 - 3/16(x-4)\\P_2(x) = 3/4 - 3/16(x-4) - 3/64(x-4)^2\\P_3(x) = 3/4 - 3/16(x-4) - 3/64(x-4)^2 + 3/256(x-4)^3\)

To find the Taylor polynomial of order 3 based at a=1 for the function \(f(x) = e^{(2^x)\), we need to find the derivatives of f at x=1 and evaluate them at a.

The derivatives of \(f(x) = e^{(2^x)\) are:

\(f'(x) = 2^x * e^(2^x) * ln(2)\\f''(x) = (2^x * ln(2))^2 * e^(2^x) + 2^x * e^(2^x) * ln(2)\\f'''(x) = (2^x * ln(2))^3 * e^(2^x) + 3 * (2^x * ln(2))^2 * e^(2^x) * ln(2) + 2^x * e^(2^x) * ln(2)\)

Evaluating the derivatives at x=1:

\(f'(1) = 2 * e^2 * ln(2)\\f''(1) = (2 * ln(2))^2 * e^2 + 2 * e^2 * ln(2)\\f'''(1) = (2 * ln(2))^3 * e^2 + 3 * (2 * ln(2))^2 * e^2 * ln(2) + 2 * e^2 * ln(2)\)

The Taylor polynomial of order 3 based at a=1 is given by:

\(P_3(x) = f(1) + f'(1)(x-1) + f''(1)(x-1)^2/2! + f'''(1)(x-1)^3/3!\)

To find the Taylor polynomials of orders 0, 1, 2, and 3 generated by f(x) = 7ln(x) at a=1, we need to evaluate the function and its derivatives at x=1.

f(1) = 7ln(1)

= 7 * 0

= 0 (constant term)

f'(x) = 7 * 1/x

f'(1) = 7 * 1/1

= 7

\(f''(x) = -7/x^2\\f''(1) = -7/1^2\\ = -7\)

\(f'''(x) = 14/x^3\\f'''(1) = 14/1^3 \\= 14\)

The Taylor polynomial of order 0 is simply the constant term: P0(x) = f(1) = 0.

The Taylor polynomial of order 1 is:

\(P_1(x) = f(1) + f'(1)(x-1)\)

= 0 + 7(x-1)

= 7x - 7

The Taylor polynomial of order 2 is:

\(P_2(x) = f(1) + f'(1)(x-1) + f''(1)(x-1)^2/2! \\= 0 + 7(x-1) - 7(x-1)^2/2\)

The Taylor polynomial of order 3 is:
