To calculate the probability, we need to determine the number of students who drive and live farther than 5 miles away, and divide it by the total number of students in the class.
Given:
Total number of students = 27
Number of students who drive = 18
Number of students who drive from farther than 5 miles away = 12
To calculate the probability, we divide the number of students who drive from farther than 5 miles away by the total number of students:
Probability = Number of students who drive from farther than 5 miles away / Total number of students
Probability = 12 / 27
Simplifying the fraction, we get:
Probability = 4 / 9
Therefore, the probability that a student who drives lives farther than 5 miles away is 4/9 or approximately 0.444.

Answer:
sorry the image is not their
Step-by-step explanation:i would help if you give me the picture.
when using your calculator, please indicate the function used and the parameters you entered for the function. 1. The selling prices of various homes in a community follow a normal distribution with a mean of $276,000.00 and standard deviation of $32,000.00. a. Calculate the probability that the next home in the neighborhood will sell for less than $220,000.00. Label the mean, standard deviation, and indicate the appropriate area on the included graph of a normal distribution. b. Calculate the probability that the next home in the community will sell for less than $350,000.00 but more than $250,000.00. Label the mean, standard deviation, and indicate the appropriate area on the included graph of a normal distribution.
On the graph of the normal distribution, we would label the mean as 276,000, the standard deviation as 32,000, and shade the appropriate area to represent the probabilities we calculated.
To calculate the probabilities, we will use the normal distribution function on the calculator. The parameters we will enter are the mean, standard deviation, and the values we are interested in finding the probability for.
a. To find the probability that the next home will sell for less than $220,000.00, we need to calculate the z-score first.
z-score = (220,000 - 276,000) / 32,000 = -1.75
Using the calculator, we will enter the function:
normdist(-1.75, 0, 1, TRUE)
where -1.75 is the z-score, 0 is the mean, 1 is the standard deviation, and TRUE indicates that we want to find the area to the left of the z-score.
The result is 0.0401, which means there is a 4.01% chance that the next home will sell for less than $220,000.00.
b. To find the probability that the next home will sell for less than $350,000.00 but more than $250,000.00, we need to calculate the z-scores for both values.
z-score for $350,000 = (350,000 - 276,000) / 32,000 = 2.31
z-score for $250,000 = (250,000 - 276,000) / 32,000 = -0.81
Using the calculator, we will enter the function:
normdist(2.31, 0, 1, TRUE) - normdist(-0.81, 0, 1, TRUE)
where 2.31 and -0.81 are the z-scores for $350,000 and $250,000 respectively, 0 is the mean, 1 is the standard deviation, and TRUE indicates that we want to find the area to the left of the z-scores.
The result is 0.3758, which means there is a 37.58% chance that the next home will sell for less than $350,000.00 but more than $250,000.00.

Fernando Garza’s firm wishes to use factor rating to help select an outsourcing provider of logistics services.
a) With weights from 1–5 (5 highest) and ratings 1–100 (100 highest), use the following table to help Garza make his decision:
RATING OF LOGISTICS PROVIDERS
CRITERION WEIGHT OVERNIGHT SHIPPING WORLDWIDE DELIVERY UNITED FREIGHT
Quality 5 90 80 75
Delivery 3 70 85 70
Cost 2 70 80 95
b) Garza decides to increase the weights for quality, delivery, and cost to 10, 6, and 4, respectively. How does this change your conclusions? Why?
c) If Overnight Shipping’s ratings for each of the factors increase by 10%, what are the new results?
The changes in weights (b) did not affect the decision as Worldwide Delivery remained the most suitable provider. However, the increase in ratings for Overnight Shipping (c) resulted in it becoming the most suitable outsourcing provider according to the given criteria.
1) Factor rating
2) Outsourcing provider
3) Logistics services
4) Weights
5) Ratings
a) Factor rating is a method used to evaluate and select an outsourcing provider based on predetermined criteria. In this case, Fernando Garza's firm wants to select a logistics services provider using factor rating. The table provided includes the weights assigned to different criteria (quality, delivery, and cost) and the ratings of three potential providers (Overnight Shipping, Worldwide Delivery, and United Freight).
To make his decision, Garza needs to multiply the weight of each criterion by the rating of each logistics provider and sum up the results. The highest sum indicates the most suitable outsourcing provider. Let's calculate the results:
Overnight Shipping:
Quality: 5 (weight) x 90 (rating) = 450
Delivery: 3 (weight) x 70 (rating) = 210
Cost: 2 (weight) x 70 (rating) = 140
Total: 450 + 210 + 140 = 800
Worldwide Delivery:
Quality: 5 (weight) x 80 (rating) = 400
Delivery: 3 (weight) x 85 (rating) = 255
Cost: 2 (weight) x 80 (rating) = 160
Total: 400 + 255 + 160 = 815
United Freight:
Quality: 5 (weight) x 75 (rating) = 375
Delivery: 3 (weight) x 70 (rating) = 210
Cost: 2 (weight) x 95 (rating) = 190
Total: 375 + 210 + 190 = 775
Based on these calculations, Worldwide Delivery has the highest total score of 815, making it the most suitable outsourcing provider according to the given criteria.
b) Garza decides to increase the weights for quality, delivery, and cost to 10, 6, and 4, respectively. This change means that Garza now considers quality to be twice as important as before, delivery to be 1.5 times as important, and cost to be twice as important.
Let's recalculate the results with the updated weights:
Overnight Shipping:
Quality: 10 (weight) x 90 (rating) = 900
Delivery: 6 (weight) x 70 (rating) = 420
Cost: 4 (weight) x 70 (rating) = 280
Total: 900 + 420 + 280 = 1600
Worldwide Delivery:
Quality: 10 (weight) x 80 (rating) = 800
Delivery: 6 (weight) x 85 (rating) = 510
Cost: 4 (weight) x 80 (rating) = 320
Total: 800 + 510 + 320 = 1630
United Freight:
Quality: 10 (weight) x 75 (rating) = 750
Delivery: 6 (weight) x 70 (rating) = 420
Cost: 4 (weight) x 95 (rating) = 380
Total: 750 + 420 + 380 = 1550
With the updated weights, the new results show that Worldwide Delivery still has the highest total score of 1630, making it the most suitable outsourcing provider.
c) If Overnight Shipping's ratings for each of the factors increase by 10%, we need to recalculate the results while considering these changes.
Overnight Shipping:
Quality: 10 (weight) x (90 + 10% of 90) = 990
Delivery: 6 (weight) x (70 + 10% of 70) = 462
Cost: 4 (weight) x (70 + 10% of 70) = 308
Total: 990 + 462 + 308 = 1760
With the increased ratings, Overnight Shipping now has the highest total score of 1760, making it the most suitable outsourcing provider.
In summary, the changes in weights (b) did not affect the decision as Worldwide Delivery remained the most suitable provider. However, the increase in ratings for Overnight Shipping (c) resulted in it becoming the most suitable outsourcing provider according to the given criteria.

Soda can make up nice real-world statistics. For example, do you suppose that taste tests for New Coke led them to make the change the formula (for those of us old enough to remember that event) but looking too close at that quantitative data caused them to overlook other qualitative data, like perhaps a negative reaction to an iconic brand that would tank sales? They were inferring something (future sales) from only the data they had. Is anyone perhaps familiar with the term "GIGO"?
According to the case study on the new coke I found, Coca-Cola spent $4 million (way back when) on market research and concluded from its research and blind taste tests that people preferred the new formula. Unfortunately, they did not do a study to understand the "emotional attachment" consumers had with the classic coke. After launching the new formula, people were outraged, and Coca-Cola responded by returning to the original formula.
In this example the company did follow the statistics illustrated from the marketing research and ultimately made a very serious error. We could measure taste on a quantitative scale (for example 1 = really don’t like taste and 10 = really like taste) but the emotional attachment would be qualitative (not able to quantify).
Soda can make up nice real-world statistics. For example, do you suppose that taste tests for New Coke led them to make the change the formula (for those of us old enough to remember that event) but looking too close at that quantitative data caused them to overlook other qualitative data, like perhaps a negative reaction to an iconic brand that would tank sales? They were inferring something (future sales) from only the data they had. Is anyone perhaps familiar with the term "GIGO"?
"GIGO," which stands for "Garbage In, Garbage Out." It refers to the concept that if you input flawed or inaccurate data into a system or analysis, the output or results will also be flawed or inaccurate.
In the case of New Coke, it seems that Coca-Cola relied heavily on quantitative data, such as taste tests, to determine consumer preferences for the new formula. However, they overlooked the qualitative data related to the emotional attachment consumers had with the classic Coke brand. This oversight led to a significant error in judgment, as people reacted negatively to the change, resulting in outrage and a decline in sales.
This example demonstrates the limitations of relying solely on quantitative data and the importance of considering qualitative factors when making business decisions. By focusing solely on taste test results and neglecting the emotional attachment consumers had with the iconic brand, Coca-Cola failed to capture the full picture of consumer sentiment and made a costly mistake.
In summary, while quantitative data can provide valuable insights, it's crucial to consider qualitative factors and gather a comprehensive understanding of the situation to make informed decisions and avoid potential pitfalls.

Suppose you are given two ordered pairs A and B. Explain how to write the equation of a line parallel to AB through a given point.
Answer: To write the equation of a line parallel to AB through a given point, we need to follow these steps:
Find the slope of the line AB. The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:
m = (y2 - y1)/(x2 - x1)
Let the coordinates of points A and B be (x1, y1) and (x2, y2) respectively. Then, the slope of the line AB is:
m = (y2 - y1)/(x2 - x1)
Since we want to find the equation of a line parallel to AB, the slope of this line will also be equal to m.
Let the given point be (x0, y0). Using the point-slope form of the equation of a line, we can write the equation of the line passing through (x0, y0) with slope m as:
y - y0 = m(x - x0)
Substituting the value of m found in step 1, we get:
y - y0 = (y2 - y1)/(x2 - x1) * (x - x0)
This is the equation of the line parallel to AB passing through the point (x0, y0).
Note that we assume that the line passing through A and B exists and is not vertical. If the line is vertical, then its slope is undefined, and we cannot find the equation of a parallel line using this method. In that case, we need to use a different method to find the equation of the line.

4. A person wants to buy a car from Toyota Company. If the price of car
including VAT is Birr 5,000,000 then,
a) What is the price of car before VAT?
b) What is the value of VAT?
Answer:
Step-by-step explanation:a) To find the price of the car before VAT, we need to first calculate the percentage of VAT included in the price:
VAT% = (VAT / Total Price) x 100
where VAT% is the percentage of VAT, VAT is the value of VAT, and Total Price is the price of the car including VAT.
From the given information, we have:
Total Price = Birr 5,000,000
VAT% = 15% (assuming a VAT rate of 15% in Ethiopia)
Therefore, we can solve for the value of the car before VAT as follows:
Total Price = Car Price + VAT
Birr 5,000,000 = Car Price + 0.15Car Price
Birr 5,000,000 = 1.15Car Price
Car Price = Birr 4,347,826.09
So the price of the car before VAT is Birr 4,347,826.09.
b) To find the value of VAT, we can use the same formula as above and solve for VAT:
Total Price = Car Price + VAT
Birr 5,000,000 = Birr 4,347,826.09 + VAT
VAT = Birr 652,173.91
Therefore, the value of VAT is Birr 652,173.91.
If the assumptions for the large sample confidence interval for the population proportion are not met, what adjustments can be made?.
A confidence interval is made up of the mean of your estimate plus and minus the estimate's range. This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence.
A 95% confidence interval gives you a 5% chance of being wrong. A 90% confidence interval gives you a 10% chance of being wrong. In comparison to a 99% confidence interval, a 95% confidence interval is smaller (for example, plus or minus 4.5 percent instead of 3.5 percent).
When constructing a confidence interval for a propotion, if the condition of proportion requires 10 individuals in each category is not met, then confidence interval should be adjusted.
The number of individuals in each category is increased by 2 and sample size increases by 4.

a train ride is $2.85 per ride. a commuter can purchase an unlimited-ride card for $45 per month. how many rides are required for a commuter to save money by buying the card?
\(-$42.15/$2.85 = 14.79 ≈ 15\): This means that a commuter must take the train 15 times to make it worth purchasing an unlimited-ride card rather than paying for each individual ride.
To find out how many rides are required for a commuter to save money by buying the card, the following steps must be followed;
Step 1: Subtract $45 from $2.85 to determine how many times a commuter must take the train to pay the same amount as the unlimited-ride card.
This calculation gives us a net value of $2.85 - $45 = -$42.15
Step 2: Divide the result from Step 1 by $2.85 to determine how many times a commuter must take the train to pay the same amount as the unlimited-ride card.
So,
\(-$42.15/$2.85 = 14.79 \\≈ 15\)
This means that a commuter must take the train 15 times to make it worth purchasing an unlimited-ride card rather than paying for each individual ride.
