Step-by-step explanation:

The probability of selecting a user who chooses cinnamon and is under 13 years old is: 0.18 or 18% (rounded to two decimal places).

In the problem, we are given the number of users who choose bacon and are under 13 years old, which is 8. We are also given the number of users who choose plain and are under 13 years old, which is 5. Therefore, the total number of users under 13 years old is 8 + 5 = 13.

Next, we are asked to find the probability of selecting a user who chooses cinnamon and is under 13 years old. We know that the number of users who choose cinnamon and are under 13 years old is 3. Therefore, out of the total 13 users under 13 years old, the probability of selecting a user who chooses cinnamon and is under 13 years old is:

The total number of users under 13 years old is 8 (choose bacon) + 5 (choose plain) = 13.

The number of users who choose cinnamon and are under 13 years old is 3.

Therefore, the probability of selecting a user who chooses cinnamon and is under 13 years old is:

3 / 13 ≈ 0.23 or 23% (rounded to two decimal places)

The population of the bees when it was first measured was 500 bees

The bees are  growing by the same factor each week. The answer is yes

At the fist time the bees where measured, we have to measure from the origin of the graph.

The first point on the graph is at the population of 500

2. To get if the growth is by the same factor, we have to observe how the growth is taking place weekly

In the first week, it grew from 500 to 1000

1000 / 500 = 2

In the second week, the growth is from 2000 to 1000

2000 / 1000 = 2

In the third week. the growth is from 2000 to 4000

4000 / 2000 = 2

Hence there is a growth constant of 2 across the weeks

The running back gained a total of 80.3 yards during the game. The correct answer is option b 80.3 yards.

Let's solve the given problem. Since the running back gained an average of 12.1 yards per carry, the total yards he gained in the first half of the game can be given as follows:

Total yards gained in the first half of the game = Average yards gained per carry x Number of carries

= 12.1 x 8= 96.8 yards

Now, the running back had a net loss of 16.5 yards in the second half of the game.

Total yards lost in the second half of the game = 16.5 yards

Therefore, the total yards gained during the game can be found as the difference between the total yards gained in the first half of the game and the total yards lost in the second half of the game.

Total yards gained during the game = Total yards gained in the first half of the game - Total yards lost in the second half of the game= 96.8 - 16.5= 80.3 yards

Hence, the running back gained a total of 80.3 yards during the game.

Therefore, the correct option is B) 80.3 yards.

The expected number of mismatches is 24.

In a certain store, the probability of a scanned price not matching the advertised price is 0.03. The cashier scans 788 items, and we want to find the expected number of mismatches. To calculate this, we multiply the probability of a mismatch (0.03) by the number of items scanned (788).

Expected Number of Mismatches = Probability of Mismatch × Number of Items Scanned

                          = 0.03 × 788

                          = 23.64

Rounding to the nearest whole number, the expected number of mismatches is 24. This means that, on average, we can expect approximately 24 items out of the 788 scanned to have a mismatch between the scanned price and the advertised price.

Expected value, or the expected number of mismatches in this case, is a mathematical concept used to determine the average outcome of a random event. It is calculated by multiplying the probability of each possible outcome by its corresponding value and summing them up. In this case, we multiplied the probability of a mismatch (0.03) by the number of items scanned (788) to find the expected number of mismatches. This helps businesses estimate potential discrepancies and plan for potential issues that may arise during sales transactions.

The case fatality rate is 400 * 100 / 1500 = 26.67 (option d).

For the first scenario, the data determine that there is a difference in average expenditure between the two countries (option c). The P-value of 0.063 suggests that there is a moderate level of statistical significance, indicating that the difference in average expenditure is likely not due to random chance.

In the second scenario, the fact that the 95% confidence interval for the average number of times participants saw their provider per year (3.3) ranges from 0.1 to 6.1 is of statistical use because it provides a range estimate within which the true population means is likely to fall. This interval helps account for the uncertainty associated with the sample estimate and provides a measure of the precision of the estimate (option a).

For the third scenario, the average operating margin is appropriate to use because it is a measure of central tendency that represents the typical financial performance of rural hospitals. The standard deviation provides information about the variability of the operating margins (option d).

In the fourth scenario, the consideration factor that will ultimately contribute to the spread of Ebola is the population density of the affected area (option b). While factors like the influence of non-indigenous people and climatic conditions may play a role, population density is a key determinant in the transmission and spread of infectious diseases.

For the fifth scenario, the case fatality rate is calculated by dividing the number of deaths from the disease (400) by the total reported cases (1500) and multiplying by 100. Therefore, the correct calculation is 400 * 100 / 1500 = 26.67 (option d). This indicates that the case fatality rate is approximately 26.67%.

To find the volume V of the solid obtained by rotating the region bounded by the curves x = \(2 + (y - 5)^2\)and x = 11 about the x-axis using the method of cylindrical shells, we can follow these steps:

Determine the limits of integration. Since we are rotating about the x-axis, we need to find the x-values where the curves intersect. Set the two equations equal to each other and solve for y:

\(2 + (y - 5)^2 = 11\)

Simplifying, we get:

(y - 5)^2 = 9

Taking the square root, we have:

y - 5 = ±3

This gives us two values for y: y = 2 and y = 8. So the limits of integration for y are from 2 to 8.

In this case, the radius r is given by x (since we are rotating about the x-axis) and the height h is the difference between the x-values of the two curves at each y-value.

The radius r = x = 11 - (y - 5)^2, and the height h = 11 - (2 + (y - 5)^2). Therefore, the integral becomes:

V =\(∫(2π(11 - (y - 5)^2)(11 - (2 + (y - 5)^2)))dy\)

Evaluate the integral by integrating with respect to y over the given limits of integration:

V = \(∫[2π(11 - (y - 5)^2)(11 - (2 + (y - 5)^2))]\)dy from 2 to 8

After evaluating the integral, you will obtain the volume V of the solid.

The number of cows needed to satisfy the beef appetite would be 5263

With an average yield of 570 pounds (258.1 Kg.) of prepared beef per cow, we need to determine how many people can be fed from this amount. The number of people fed per cow can vary depending on various factors such as portion sizes and individual dietary preferences. Assuming a reasonable estimate, let's consider that one pound (0.45 Kg.) of prepared beef can feed about three people.

To find the number of cows needed to satisfy the beef appetite for New York City's population of approximately 9,000,000 people, we divide the population by the number of people fed by one cow. Thus, the calculation becomes 9,000,000 / (570 pounds x 3 people/pound).

After simplifying the equation, we get 9,000,000 / 1710 people, which equals approximately 5,263 cows. However, it's important to note that this is a rough estimate and does not consider factors such as variations in consumption patterns, distribution logistics, or other sources of meat supply. Additionally, individual dietary choices and preferences may result in different consumption rates. Therefore, this estimate serves as a general indication of the number of cows needed to satisfy the beef appetite for New York City's population.

In a strongly right-skewed data set, the median will be smaller than the mean. This implies that the majority of the data points are concentrated towards the lower end of the distribution, resulting in a longer tail on the right side.

The median represents the middle value of a data set when arranged in ascending order. Since the tail on the right side of the distribution is stretched due to the skewness, the median will be pulled towards the lower values, making it smaller than the mean.

The mean, on the other hand, takes into account the values of all data points and is influenced by extreme values. In a right-skewed distribution, the presence of a few very high values on the right side can significantly increase the mean. Therefore, the mean will be larger than the median, indicating the overall shift towards higher values caused by the skewness.

The volume of the solid obtained by rotating the region bounded by y=9x^4, y=9x, x>=0, about the x-axis is determined.

To find the volume of the solid, we can use the method of cylindrical shells. Consider an infinitesimally thin vertical strip of width dx at a distance x from the y-axis. The height of this strip is the difference between the functions y=9x^4 and y=9x.

The circumference of the cylindrical shell is 2πx (since we are rotating about the x-axis), and the height of the shell is given by (9x^4 - 9x). The volume of the shell is then given by dV = 2πx(9x^4 - 9x)dx. To obtain the total volume, we integrate this expression from x=0 to x=1 (where the two curves intersect).

Thus, the volume is V = ∫(0 to 1) 2πx(9x^4 - 9x)dx, which can be calculated using integral calculus.
