The number of conversions Mrs. Yellow's company can achieve is 10, and the revenue they can earn is $10,000.

Mrs. Yellow is an email marketing manager and her company has the following characteristics:

20% open rate, 5% click-through rate, 5% conversion rate, and $1000 average order value. She is sending the promotion email to a list of 20000 members.

To calculate the number of conversions and revenue, we need to use the following formula:

Revenue = Number of conversions × Average order value

Number of conversions = Total number of emails × Conversion rate

Total number of emails = Total number of opened emails × Click-through rate

Total number of opened emails = Total number of sent emails × Open rate

Total number of sent emails = 20,000

Revenue = Number of conversions × Average order value

Total number of sent emails = 20,000

Total number of opened emails = 20,000 × 20/100 = 4,000

Total number of emails = 4,000 × 5/100 = 200

Number of conversions = 200 × 5/100 = 10

Revenue = 10 × 1,000 = $10,000

a.  The 68% of the widget weights lie between  33 ounces and  55 ounces.

b. The percentage of widget weights lying between 11 and 55 ounces is approximately 68%.

c. The percentage of widget weights lying above 22 ounces is approximately = 5%.

Based on the given data points: 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, the five-number summary can be identified as follows:

Minimum: 5

First Quartile (Q1): 7

Median (Q2): 11

Third Quartile (Q3): 15

Maximum: 18

Now, let's answer the questions related to the distribution of widget weights using the Empirical Rule:

a) The Empirical Rule states that for a bell-shaped distribution, approximately 68% of the data lies within one standard deviation of the mean. Since the mean is 44 ounces and the standard deviation is 11 ounces, we can say that approximately 68% of the widget weights lie between 44 - 11 = 33 ounces and 44 + 11 = 55 ounces.

b) To determine the percentage of widget weights lying between 11 and 55 ounces, we need to calculate the z-scores for these values. The z-score is calculated using the formula: z = (x - mean) / standard deviation.

For 11 ounces: z1 = (11 - 44) / 11 = -33/11 = -3

For 55 ounces: z2 = (55 - 44) / 11 = 11/11 = 1

Using the Empirical Rule, we know that approximately 68% of the data lies within one standard deviation of the mean. Therefore, the percentage of widget weights lying between 11 and 55 ounces is approximately 68%.

c) To determine the percentage of widget weights lying above 22 ounces, we need to calculate the z-score for 22 ounces: z = (22 - 44) / 11 = -22/11 = -2.

Using the Empirical Rule, we know that approximately 95% of the data lies within two standard deviations of the mean. Therefore, the percentage of widget weights lying above 22 ounces is approximately 100% - 95% = 5%.

In Euler's Formula for graphs that are not necessarily connected states that the number of vertices minus the number of edges plus the number of connected components is equal to the Euler characteristic of the graph.

Euler's Formula, which states that the number of vertices minus the number of edges plus the number of faces is equal to 2 for planar graphs, can be extended to graphs that are not necessarily connected. In this generalization, we consider the number of connected components in the graph. A connected component is a subgraph where there is a path between any two vertices.

Let V be the number of vertices, E be the number of edges, C be the number of connected components, and X be the Euler characteristic of the graph. The generalization of Euler's Formula for non-connected graphs is given by V - E + C = X.

To prove this formula, we start with Euler's Formula for connected graphs, which states V - E + F = 2, where F is the number of faces. For a disconnected graph, the number of faces can be defined as the sum of the number of faces in each connected component minus the number of edges that belong to more than one connected component. This can be written as F = F1 + F2 + ... + FC - N, where Fi is the number of faces in the i-th connected component and N is the number of edges connecting different components.

By substituting F = F1 + F2 + ... + FC - N into Euler's Formula for connected graphs and rearranging terms, we get V - E + C = X, which is the generalization of Euler's Formula for non-connected graphs. Therefore, the formula holds true for any graph, whether connected or not.

Answer:

72°

Step-by-step explanation:

From the question,

Area of the circle = πr²

A = πr²................. Equation 1

Where r = radius of the circle.

⇒ r = √(A/π)............. Equation 2

Given: A = 346.5 cm², π = 3.14

r = √(346.5/3.14)

r = √(110.35)

r = 10.5 cm.

Therefore,

circumference of the circle = 2πr = 2×3.14×10.5

circumference = 65.94 m

If the length of the arc(s) is 1/5 of its circumference.

Therefore, length of arc (s) = 13.188

⇒ length of arc/circumference = 13.188/65.94 =  1/5

s/2πr = θ/360

Where θ = angle substends at the center of the circle

1/5 = θ/360

Answer:

The population of the town in Iowa after 13 years is 9,130

Step-by-step explanation:

The given parameters of the town are;

The population of the town in Iowa in 2007, a = 12,355

The rate at which the people of the town leave Iowa for Minnesota, r = 2.3% per year

We are required to find the population of the town after t = 13 years

The given population decay function is presented as follows;

[tex]f(t) = a \cdot (1 - r)^t[/tex]

Where;

a = The initial population of the town = 12,355

r = The annual percentage rate at which the people of the town leave Iowa for Minnesota = 2.3% per year = 0.023

t = The number of years over which the population changes = 13 years = 13

∴ f(13) = 12,355 × (1 - 0.023)¹³ = 9130.02734094

Therefore, the population of the town in Iowa after 13 years ≈ 9,130 (we round down to the nearest whole number).

The correct answer to 0.125 x 0.08 is 0.01. Dina's calculator provided the correct result.

The rule Dina mentioned about multiplying 125 x 8 and then moving the decimal point 5 places is not applicable in this case. When multiplying decimal numbers, we need to consider the number of decimal places in each factor.

Here's the correct approach to multiply 0.125 x 0.08:

Step 1: Ignore the decimal point and multiply the numbers as if they were whole numbers:

0.125 x 0.08 = 125 x 8

Step 2: Count the total number of decimal places in the original numbers:

0.125 has three decimal places

0.08 has two decimal places

Step 3: Add the number of decimal places from the original numbers:

Three decimal places + two decimal places = five decimal places

Step 4: Place the decimal point in the result by counting five places from the right:

125 x 8 = 1000

Adding the decimal point five places from the right gives us the final answer: 0.01000

Therefore, the correct answer to 0.125 x 0.08 is 0.01. Dina's calculator provided the correct result.

It is a fundamental concept in statistical inference and scientific research.

The hypothesis is a statement that the value of a population parameter is equal to some claimed value. A hypothesis serves as a proposed explanation or prediction about the population based on existing knowledge or observations. In statistical hypothesis testing, two types of hypotheses are considered: the null hypothesis (H0) and the alternative hypothesis (Ha). The null hypothesis assumes no significant relationship or difference between variables, while the alternative hypothesis suggests the presence of a significant relationship or difference.

Hypothesis testing involves collecting sample data and performing statistical analysis to evaluate the evidence against the null hypothesis. The goal is to determine whether the data provides enough evidence to reject the null hypothesis in favor of the alternative hypothesis. This process allows researchers to make conclusions about the population based on the available evidence.

Hypothesis testing provides a framework for making objective and informed decisions in various fields of study, such as psychology, biology, economics, and more. It enables researchers to validate or challenge theories, investigate causal relationships, and contribute to the advancement of knowledge in their respective disciplines.

The specificity of the diagnostic test is 88%, indicating its ability to accurately identify individuals without the disease as negative.

Specificity is a measure of the test's ability to correctly identify individuals without the disease as negative. To calculate the specificity, we need to consider the number of true negatives (controls who yield negative tests) and the total number of controls.

In this case, the number of controls tested is 250, and out of those, 30 yield positive tests. The number of true negatives can be calculated by subtracting the number of false positives (controls who yield positive tests) from the total number of controls:

Negatives which are true = Total Controls - False Positives

True Negatives = 250 - 30 = 220

The specificity is then calculated as the ratio of true negatives to the total number of controls:

Specificity = True Negatives / Total Controls

Specificity = 220 / 250 ≈ 0.88

Therefore, the specificity of this test is approximately 0.88 or 88%. This means that the test correctly identifies 88% of individuals without the disease as negative.

1. 2,3,3*

 Statistics 1: Sum of the values = 2 + 3 + 3 = 8

 Statistics 2: Average of the values = (2 + 3 + 3) / 3 = 2.67

 Statistics 3: Median of the values = 3

2. 2,3,4

   Statistics 1: Sum of the values = 2 + 3 + 4 = 9

   Statistics 2: Average of the values = (2 + 3 + 4) / 3 = 3

   Statistics 3: Median of the values = 3

3.  2,3,4*

    Statistics 1: Sum of the values = 2 + 3 + 4 = 9

    Statistics 2: Average of the values = (2 + 3 + 4) / 3 = 3

    Statistics 3: Median of the values = 3

4. 2,3*,4*

Statistics 1: Sum of the values = 2 + 3 + 4 = 9

Statistics 2: Average of the values = (2 + 3 + 4) / 3 = 3

Statistics 3: Median of the values = 3

5. 2,4,4*

Statistics 1: Sum of the values = 2 + 4 + 4 = 10

Statistics 2: Average of the values = (2 + 4 + 4) / 3 = 3.33

Statistics 3: Median of the values = 4

6. 3,3*,4

Statistics 1: Sum of the values = 3 + 3 + 4 = 10

Statistics 2: Average of the values = (3 + 3 + 4) / 3 = 3.33

Statistics 3: Median of the values = 3

7.  3,3*,4*

Statistics 1: Sum of the values = 3 + 3 + 4 = 10

Statistics 2: Average of the values = (3 + 3 + 4) / 3 = 3.33

Statistics 3: Median of the values = 3

8.  3,4,4*

Statistics 1: Sum of the values = 3 + 4 + 4 = 11

Statistics 2: Average of the values = (3 + 4 + 4) / 3 = 3.67

Statistics 3: Median of the values = 4

9.  3*,4,4*

Statistics 1: Sum of the values = 3 + 4 + 4 = 11
