Answer below :)
Step-by-step explanation:
To determine which bus is the most consistent, we need to look at the measures of variability for each bus. The two measures of variability that are commonly used are the range and the interquartile range (IQR).
The range is the difference between the maximum and minimum values in a dataset. It gives an idea of how spread out the data is but can be affected by extreme values or outliers. The IQR is a better measure of variability as it is not affected by extreme values and is a more robust measure of variability.
Looking at the given data, Bus 47 has a range of 8 and an IQR of 8, while Bus 14 has a range of 6 and an IQR of 6. This indicates that Bus 14 has less variability in its travel times than Bus 47.
Therefore, we can conclude that Bus 14 is the most consistent in terms of travel times.

The area of triangle XYZ when using YZ as the base, can be found to be 24 square units.
How to find the area ?To find the area of triangle XYZ, we can use the Shoelace Theorem (also known as the Surveyor's Formula). Given the coordinates of the vertices, the area of the triangle is:
Area = (1/2) x |(x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2))|
Plugging in the coordinates:
Area = (1/2) x |(2(9 - 1) + 10(1 - 5) + 6(5 - 9))|
Area = (1/2) x |(2(8) - 10(4) + 6(-4))|
Area = (1/2) x |(16 - 40 - 24)|
Area = (1/2) x |-48|

Brody has pulled 27 marbles from a large bag, and 12 of them are red. What is the experimental probability that the next marble selected from the bag will be red?
Answer:
Step-by-step explanation:
4/9
By the number of red marbles taken out, we expect that 12/27=4/9 of the marbles are red. Therefore, the probability of the next marble being red is 4/9.
use the given degree of confidence and sample data to construct a confidence interval for the population proportion p.when 319 college students are randomly selected and surveyed, it is found that 120 own a car. find a 99% confidence interval for the true proportion of all college students who own a car.
The required 99% confidence interval representing the true proportion of all college students owns a car lies between the range of 0.3253 and 0.4283.
Sample size n = 319
Students who own a car represents the number of successes x = 120
Confidence interval = 99%
True proportion p of all college students who own a car.
The formula for the confidence interval for a population proportion is,
p1± zα/2 × √(p1(1-p1)/n)
where p1 is the sample proportion,
zα/2 is the z-score corresponding to the desired level of confidence interval 99%.
First, we find the sample proportion,
p1 = x/n
= 120/319
≈ 0.3768
z-score corresponding to a 99% confidence level.
This is a two-tailed test,
Split the alpha level evenly between the two tails.
α/2 = (1 - 0.99) / 2
= 0.005,
The z-score that encloses 0.005 in each tail of the standard normal distribution.
Using a standard normal table ,
zα/2 = 2.576.
Substituting the values into the formula, we get,
p1 ± zα/2 × √(p1(1-p1)/n)
= 0.3768 ± 2.576×√(0.3768(1-0.3768)/319)
= 0.3768 ± 0.0515
99% confidence interval for the true proportion p of all college students who own a car is,
0.3253 ≤ p ≤ 0.4283
Therefore, 99% confidence interval that the true proportion of all college students who own a car lies between 0.3253 and 0.4283.

as the sample size becomes larger, the sampling distribution of the sample mean approaches a . a. binomial distribution b. poisson distribution c. hypergeometric distribution
As the sample size becomes larger, the sampling distribution of the sample mean approaches a normal distribution. Correct option is D.
This is known as the central limit theorem, which states that the sampling distribution of the sample mean is approximately normal regardless of the underlying population distribution, as long as the sample size is sufficiently large.
The central limit theorem is a fundamental result in statistics and has many practical applications. For example, it allows us to use the normal distribution to make inferences about population parameters based on sample statistics, such as constructing confidence intervals or conducting hypothesis tests.
On the other hand, the binomial distribution describes the number of successes in a fixed number of independent trials with a constant probability of success, while the Poisson distribution describes the number of rare events that occur in a fixed interval of time or space.
The hypergeometric distribution describes the probability of drawing a specified number of objects of interest from a population of known size without replacement. These distributions are not related to the sampling distribution of the sample mean and do not converge to a normal distribution as the sample size increases.
Therefore, the correct option is D.

The pentagon ABCDE has been divided into six isosceles triangles, which all have the same perimeter. The triangle ABC is even equilateral. What is the ratio of the perimeter of the triangle ABC to the perimeter of the pentagon ABCDE?
A) 1:3
B) 4:9
C) 3:7
D) 9:16
E) 5:8
Answer:
Unfortunately, none of the answer choices match. A correct ratio would be 1:2.
Step-by-step explanation:
Let the perimeter of each isosceles triangle be "2x". Since ABC is equilateral, each of its sides is also "2x".
The perimeter of the pentagon is the sum of the perimeters of the triangles, which is 6(2x) = 12x.
Since ABC is equilateral, its perimeter is 6x (since it has three sides of length 2x).
Therefore, the ratio of the perimeter of ABC to the perimeter of ABCDE is (6x)/(12x) = 1/2, simplifying this ratio gives 1:2.
Therefore, the correct answer is not given in the options.

1Which equation shows a way to solve ⅚ / ⅔ ?
Answer:
To divide fractions, we can use the reciprocal (or multiplicative inverse) of the second fraction and then multiply the two fractions.
So to solve ⅚ ÷ ⅔, we can write it as:
⅚ ÷ ⅔ = ⅚ × (⅔)⁻¹
where (⅔)⁻¹ is the reciprocal of ⅔, which is 3/2.
So we have:
⅚ ÷ ⅔ = ⅚ × (⅔)⁻¹ = ⅚ × 3/2
We can simplify this expression by canceling out a common factor of 2 in the numerator and denominator:
⅚ ÷ ⅔ = ⅚ × (⅔)⁻¹ = ⅚ × 3/2 = (⅚ × 3) / 2 = 9/12
Therefore, another way to solve ⅚ ÷ ⅔ is the equation:
⅚ ÷ ⅔ = 9/12

a survey asked 215 people what alternative transportation modes they use. the results are below. 144 walk 102 use the bus 105 ride a bicycle 78 walk and use the bus 65 walk and ride a bicycle 45 ride the bus and ride a bicycle 34 said they use all three modes of transportation. how many people don't use any alternate transportation
The number of people who don't use any alternative transportation mode is 18 people.
To find the number of people who don't use any alternative transportation mode we can use the principle of inclusion and exclusion (PIE) method.
adding the number of people who use each mode:
walk = 144
bus = 102
bicycle = 105
Next, subtract the number of people who use two modes:
walk and bus = 78
walk and bicycle = 65
bus and bicycle 45
adding people who use all three modes:
all three modes of transportation = 34
Therefore, the total number of people who use at least one alternative mode of transportation is:
= 144 + 102 + 105 - 78 - 65 - 45 + 34
= 197
To find the number of people who don't use any alternative transportation. we need to subtract the number of people who use at least one alternative mode of transportation from the total number of people in the survey:
= 215 - 197
= 18
Therefore, The number of people who don't use any alternative transportation mode is 18.

(b) what is the necessary sample size for future surveys such that a 99% confidence interval for p has an interval width of no more than 6%? is this sample size the same as, or smaller or larger than that from problem 4.6-21 (b)?
a) The necessary sample size for a 95% confidence interval with an interval width of no more than 6% is 147.
b) The necessary sample size for a 99% confidence interval with an interval width of no more than 6% is 263.
(a) To find the necessary sample size for future surveys such that a 95% confidence interval for p has an interval width of no more than 6%, we use the formula:
n = (Zα/2/ME)² × p(1-p)
where Zα/2 is the Z-score for the desired confidence level (1.96 for 95% confidence), ME is the margin of error (0.06), and p is the estimated proportion of patients with pain relief from the pilot survey (14/20 = 0.7). Substituting these values into the formula, we get:
n = (1.96/0.06)² × 0.7(1-0.7) = 146.95
Therefore, This sample size is larger than the sample size in problem 4.6-21(a), which was 100.
(b) To find the necessary sample size for future surveys such that a 99% confidence interval for p has an interval width of no more than 6%, we use the same formula as above but with a Z-score of 2.576 for 99% confidence:
n = (2.576/0.06)² × 0.7(1-0.7) = 262.43

why are the mean and standard deviation used to compaer the center and spread of two symmetrical distributions and why are the five number summary used to compare
The mean and standard deviation are used to compare the centers and ranges of two symmetric distributions because they provide a measure of position and variability that are consistent with normally distributed data.
When the data are approximately normal, the mean is a good measure of the center of the distribution, and the standard deviation is a good measure of the spread of the distribution.
By comparing the means and standard deviations of two symmetric distributions, we can know their similarity or difference in terms of central tendency and variability.
On the other hand, a five-digit summary (minimum, Q1, mean, Q3, maximum) is used to compare the center and difference of two skewed or outlier distributions.
The five-digit summary provides a way to summarize the key characteristics of a distribution, and it is more robust for outliers than for mean and standard deviation.
By comparing the median and interquartile range (IQR) of two skewed or outlier distributions, we can tell their similarities or differences in terms of central tendency and variability.
In summary, mean and standard deviation are suitable for comparing centers and ranges of normally distributed data, while five-digit summaries are more suitable for comparing centers and ranges of skewed distributions.

a 10 foot tall ladder makes an angle of 60 degrees with the ground as it leans against a wall. how far up the wall does the ladder reach?
The ladder reaches the wall at a height of 8.66 from the ground. We solve this problem with an understanding of trigonometry.
From the given situation, we can construct a right-angled triangle where the base is the distance between the ladder and the wall, the hypotenuse is the length of the ladder i.e. 10 feet and the height up to which it reaches is perpendicular (let's assume that to be x).
We can use trigonometry's sine relation to solve this problem, according to which,
sine(60°)=perpendicular/hypotenuse
sin(60°)=x/10
0.866=x/10
so,
x=10×0.866
x=8.66

The absolute value expression in this situation is -(3x - 0.5), which is equivalent to -3x + 0.5. We thus have:
-3x + 0.5 > 1.5
The result of solving for x is: x -0.333
Example 3: (3x - 0.5) = 0
The equation for the absolute value in this situation is |0|, which equals 0. The result is either 3x - 0.5 = 1.5 or 3x - 0.5 = -1.5.
The results of each equation's x term are: x = 1 or x = 0.
As a result, the answer to |3x - 0.5| > 1.5 is either x -0.333 or x > 1.
x = 0 or x = 1 is the answer to the equation |3x - 0.5| = 1.5.
The answer to the equation |3x - 0.5| 1.5 is: -0.333 x 0.833

What are the dimensions of the existing patio?
Therefore , the correct option is A Dimension of exisiting patio is 6feet by 8feet.
Ms. Khan wants to add x feet onto each side of an existing patio, then the area of the existing patio is (x-2)² square feet.
Define square feet?
In the United States, Canada, China, and the United Kingdom, the square foot is a commonly used imperial measure of area. Its emblem is a straightforward square with a vertical line cutting it in half .
The Imperial system uses a combination of feet, inches, miles, and gallons.
So,
we can write (x-2)² = x²+14x+48.
Expanding the left side gives us x²-4x+4 = x²+14x+48.
Simplifying gives us 18x = 44.
Therefore, x = 11/4.
The dimensions of the square patio are (11/4 - 2)×2 feet by (11/4 - 2)×2 feet which is equal to( 3/4)×2 feet by 6/8

On average, Carson spends $2 of his $20 monthly allowance on library fines. When creating a circle graph of what Carson does with his money, what fraction of the circle will represent the amount he spends on library fines?
Answer:
1/10 of the circle (36° central angle).
Step-by-step explanation:
2/20 = 1/10
A circle has 360 degrees, so the central angle will be 1/10 × 360° = 36°.
Triangle A and Triangle B have the same base. The height of Triangle B is twice the height of Triangle A. How many times greater is the area of Triangle B?
The area of Triangle B is 2 times greater than the area of Triangle A.
What is are of triangle?
The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.
Area of the triangle = 1/2 h*b
For Triangle A, the area is:
Area_A = 1/2 * b * h
For Triangle B, the area is:
Area_B = 1/2 * b * 2h = b * h
So, the area of Triangle B is twice the area of Triangle A.
Therefore, the area of Triangle B is 2 times greater than the area of Triangle A.
