To solve this problem, we can use the equation: Distance = Speed x Time. Julia's trip takes 4.58 hours.

Distance is usually calculated by measuring the length or space between two points, or finding the shortest route between two points.

To solve this problem, we can use the equation:

Distance = Speed x Time

For the first part of the journey, the distance is 1/3 of 3540km, which is 1180km. We can use this distance and the speed of 720km/h to calculate the time:

Time = 1180km/720km/h

= 1.63 hours

For the second part of the journey, the distance is 2/3 of 3540km, which is 2360km.

We can use this distance and the speed of 800km/h to calculate the time:

Time = 2360km/800km/h

= 2.95 hours

Therefore, the total time for Julia's trip is

1.63 hours + 2.95 hours = 4.58 hours.

In conclusion, Julia's trip takes 4.58 hours.

Step-by-step explanation:

not sure but i think this is it

Answer:

13

Step-by-step explanation:

This is a right angle (90°).

Now, write the expression:

5x + 25 = 90

Subtract 25 from both sides:

5x + 25 = 90 ---> 5x = 65

Divide both sides by 5:

5x = 65 ---> x = 13

The measurement that gives you the difference between the points on the scatterplot and the prediction line for the same value of x is the residual. Therefore, the correct answer is C. Residual.

In regression analysis, the residual represents the vertical distance between the observed data points and the corresponding predicted values on the regression line. It is calculated by taking the difference between the actual observed value and the predicted value for a specific value of the independent variable (x). The residuals provide a measure of how well the regression line fits the data, with smaller residuals indicating a better fit.

a. The appropriate amount of safety stock is 92 kg. b. The item should be reordered when the inventory level reaches approximately 692 kg.

To determine the amount of safety stock and the reorder point (ROP), we need to consider the expected demand during the lead time, the standard deviation of demand during the lead time, and the acceptable stockout risk.

a. Amount of safety stock:

Safety stock is the additional inventory kept to mitigate the risk of stockouts. It acts as a buffer to account for unexpected fluctuations in demand. The formula to calculate safety stock is:

Safety stock = (Z * Standard deviation of demand during lead time)

Where Z is the z-score corresponding to the acceptable stockout risk. Since the acceptable stockout risk is 5 percent, we need to find the corresponding z-score.

Looking up the z-values table for a 5 percent risk (two-tailed test), the z-score is approximately 1.645.

Substituting the values into the formula:

Safety stock = (1.645 * 56)

≈ 92.12 kg

b. Reorder point (ROP):

The reorder point is the level of inventory at which an item should be reordered to ensure that it arrives before the stock runs out during the lead time. It can be calculated using the formula:

ROP = Expected demand during lead time + Safety stock

Substituting the given values:

ROP = 600 + 92

≈ 692 kg

The most effective measure of central tendency for this data is the median.

Given the following data, the most effective measure of central tendency would be the median. Here's how:

To find the mean for the given data,

we will add all the values and then divide it by the number of values:

\(41 + 33 + 33 + 31 + 21 + 23 + 28 + 28 + 28 + 27 + 17 + 18 + 17 + 30 + 21 + 23 + 14 + 16 + 26 + 26 = 478.\)

Mean \(= 478 / 20\)

\(= 23.9.\)

Now let's calculate the median by arranging the values in order:

\(14, 16, 17, 17, 18, 21, 21, 23, 23, 26, 26, 27, 28, 28, 28, 30, 31, 33, 33, 41\)

There are 20 values, and the middle two values are 26 and 27.

Therefore, the median is \((26+27)/2 = 26.5.\)

The mode is the value that appears most frequently in the data.

In this case, there is no value that appears more than once,

so there is no mode.

Standard deviation is a measure of dispersion, not central tendency,

so it is not an appropriate measure for this question.

Therefore, the most effective measure of central tendency for this data is the median.

The partial derivatives of the function f(x, y) are fx = 9y^2 and fy = 4yx^2 + 18xy, and evaluating them at the point (1, 1) gives fx(1, 1) = 9 and fy(1, 1) = 22.

To find fx and fy, we need to compute the partial derivatives of the function f(x, y) with respect to x and y, respectively.

Taking the partial derivative of f(x, y) with respect to x (fx), we treat y as a constant and differentiate each term separately:

fx = (d/dx) [9xy^2 + 2y^2]

= 9y^2 (d/dx) [x] + 0 (since 2y^2 is a constant)

= 9y^2

Taking the partial derivative of f(x, y) with respect to y (fy), we treat x as a constant and differentiate each term separately:

fy = 2 (d/dy) [y^2x^2] + (d/dy) [9xy^2]

= 2(2yx^2) + 9x(2y)

= 4yx^2 + 18xy

To evaluate fx and fy at the given point (1, 1), we substitute x = 1 and y = 1 into the expressions we obtained:

fx(1, 1) = 9(1)^2 = 9

fy(1, 1) = 4(1)(1)^2 + 18(1)(1) = 4 + 18 = 22

Therefore, fx(1, 1) = 9 and fy(1, 1) = 22.

To write a differential equation that models the rate of change for this rumor spreading situation, we need to consider both the number of students who have heard the rumor (P) and the number of students who have not heard the rumor (200 - P). Let t be the time in minutes since the rumor began to spread.

Since the rate of change is directly proportional to both P and (200 - P), we can express the rate of change as dP/dt = k * P * (200 - P), where k is the constant of proportionality.

The differential equation representing this situation is:
dP/dt = k * P * (200 - P)

This equation models the rate at which the rumor spreads among the 200 students at the dance, considering both the students who have heard the rumor (P) and those who have not (200 - P).
