Ronald rents a car from Cheap Rent-a-Car for $25 plus $0.05 per mile. Dixon rents a car
from Great Cars for S40 plus $0.03 per mile. How many miles must they both drive for
their rental fees to be the same?
Answers
Answer:
750 miles
Step-by-step explanation:
Ronald
Rental fee = fixed cost + variable cost
= $25 + $0.05x
Where x = number of miles
Dixon
Rental fee = fixed cost + variable cost
= $40 + $0.03x
How many miles must they both drive for their rental fees to be the same?
Equate the two equations
$25 + $0.05x = $40 + $0.03x
Collect like terms
0.05x - 0.03x = 40 - 25
0.02x = 15
Divide both sides by 0.02
x = 15 / 0.02

Answers
The independence assumption says that all sample respondents must do so independently, meaning they are not coerced into responding. Thus, option C is the right answer.
What is the independence assumption? The independence assumption is a term used in statistical surveys that refers to the idea that survey participants' responses are not influenced by each other. As a result, data is seen as independent because it is not influenced by any other data in the same sample. This assumption is critical since it aids in the development of statistical analysis, which is used to understand how variables relate to one another. A, B, D, and E options are not correct because:
A. Each sample needs to have a sample size of 30 or more. This is not correct because it's a condition used in the Central Limit Theorem.
B. All observations have to be drawn from the same distribution: This is not correct because the assumptions depend on the study.
C. All sample respondents must do so independently, meaning they are not coerced into responding: This is the right option because the independence assumption says that all sample respondents must do so independently, meaning they are not coerced into responding.
D. Non-response must be kept to a minimum. This is not correct because it is about survey sample bias, not independence.

The height (perpendicular line segment) of an isosceles triangle from a vertex to the base is 4 inch long.If the base of this triangle is 6 inch long, how long will the legs of this triangle be (in inches)?
Answers
Given:
Height of the isosceles triangle = 4 inches
Base of triangle = 6 inches
Let's find the length of the legs of the traingle.
Let's sketch a figure which represents this isosceles triangle.
Since the triangle is an isoceles triangle, the length of the legs will be equal.
a = b
To find the length of the legs, apply Pythagorean Theorem:
\(c^2=a^2+b^2\)Where:
a = 4 in
b = 3 in
Thus, we have:
\(\begin{gathered} c^2=4^2+3^2 \\ \\ c^2=16+9 \\ \\ c^2=25 \end{gathered}\)Take the square root of both sides:
\(\begin{gathered} \sqrt[]{c}^2=\sqrt[]{25}^2 \\ \\ c=5 \end{gathered}\)Therefore, the length of the legs of the isosceles triangle is 5 inches.
The owner of the Good Deals Store opens a new store across town. For the new store, the owner estimates that, during business hours, an average of 90 shoppers
Answers
The correct option is (A) 60 as the estimated average number of shoppers in the original store at any time is 45.
What is an average?In layman's terms, an average is a single number chosen to represent a set of numbers, usually the sum of the numbers divided by the number of numbers in the set. The average of the numbers 2, 3, 4, 7, and 9 is 5, for example.To find the estimated average number of shoppers in the original store at any time:
In the new store, the manager estimates that an average of 90 shoppers per hour enter the store, which is equivalent to 1.5 shoppers per minute. The manager also estimates that each shopper stays in the store for an average of 12 minutes. Thus, by Little’s law, there are, on average, N=rt = (1.5)(12) = 18 shoppers in the new store at any time. This is (45-18)/45 × 100 = 60 percent less than the average number of shoppers in the original store at any time.Therefore, the correct option is (A) 60 as the estimated average number of shoppers in the original store at any time is 45.

(b) Determine if w is in Span{u, v}
(c) Give a description of Span{u, v, w}. Justify your answer. (Hint: Consider the matrix A whose columns are u, v, and w.)
Answers
The span of {u, v} represents a plane in three-dimensional space. w is not in the span of {u, v}. the span of {u, v, w} is the entire three-dimensional space.
(a) The span of {u, v} represents a plane in three-dimensional space. Geometrically, this plane can be visualized as a flat surface extending infinitely in all directions. It includes all possible vectors that can be obtained by scaling and adding u and v. Any vector lying on this plane can be expressed as a linear combination of u and v.
(b) To determine if w is in the span of {u, v}, we need to check if w can be expressed as a linear combination of u and v. We can write w as follows:
w = a*u + b*v
Solving the system of equations formed by equating corresponding components, we have:
-2 = 3a - 2b
2 = -a + 2b
6 = -2a - 6b
Solving this system, we find that there are no values of a and b that satisfy all three equations simultaneously. Therefore, w is not in the span of {u, v}.
(c) The span of {u, v, w} is the entire three-dimensional space. To justify this, we consider the matrix A whose columns are u, v, and w:
A = [u v w] = [1 3 -2; -1 1 2; -2 -6 6]
We can row-reduce matrix A to its echelon form:
[1 3 -2; -1 1 2; -2 -6 6] -> [1 3 -2; 0 4 0; 0 0 0]
The echelon form shows that the columns of A are linearly independent, and they span the entire three-dimensional space. Therefore, any vector in three-dimensional space can be expressed as a linear combination of u, v, and w, indicating that the span of {u, v, w} is the entire three-dimensional space.

Answers
A customer would be charged $ 52 for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day.
Charge for first 5 charged = $ 4.50
Charge for additional time = $ 0.50 per minute
Starting time = 9:35 p.m.
End time = 11:15 p.m.
Total minutes = 100 minutes
Total charge = 4.50 + (95 x 0.50)

An ABS (Australian Bureau of Statistics) employee wishes to test the speed (in minutes) with which different online survey designs can be completed. Three different online survey designs have been proposed. One complication in assessing the surveys is the notion that individual differences might influence the speed with which the online forms are completed. To account for individual differences an experiment is arranged so that a survey from each design is completed by each individual. The following results are extracted from a randomised block experiment with three treatment levels (i.e. three types of online survey designs) and five blocks (i.e. 5 individuals). SSBL (sum of squares between blocks) = 3738, SSB (sum of squares between groups) = 1048.93 and SST (sum of squares total) = 5391.33. Based on this information, what is the critical value used to test if there is evidence of an effect due to blocks at the 5% level of significance? Use our textbook statistical table to answer the question.
Answers
The critical value used to test if there is evidence of an effect due to blocks at the 5% level of significance is 10.76.
The critical value can be determined using a statistical table.
The degrees of freedom for the blocks is 4 (df_b = 5 - 1 = 4) and for the treatments is 2 (df_t = 3 - 1 = 2).
The critical value for a 5% level of significance is 10.76.
This value can be found in the statistical table given in the textbook.
The critical value used to test if there is evidence of an effect due to blocks at the 5% level of significance can be calculated by using the F-test statistic.
The F-test is used to compare the variance between the blocks (SSBL) and the variance between the groups (SSB).
The F statistic is calculated by dividing the variance between the blocks (SSBL) by the variance between the groups (SSB).
In this case,
The F statistic is 3738/1048.93 = 3.56.
The critical value for a 5% level of significance can be found using a statistical table.
According to the table,
The critical value for an F statistic of 3.56 with four degrees of freedom in the numerator and four degrees of freedom in the denominator is 10.76

A student who was skeptical about this value decided to conduct a survey by randomly sampling 29 students. On average, the sampled students slept 5.2 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.
Answers
The sample mean of 5.2 hours represents the average sleep duration observed in the sampled group of 29 students, while the claimed population mean of 6.2 hours represents the average sleep.
In the context of statistical inference, the term "sample mean" refers to the average of a subset of data taken from a larger population, while the "population mean" represents the average of the entire population.
In this scenario, the value 6.2 hours represents the claimed population mean. This is the average sleep duration stated in the college newspaper article,
which claims to represent the average sleep time of all college students. It is an estimate of the population mean based on available information.
On the other hand, the value 5.2 hours represents the sample mean. It is the average sleep duration observed from a randomly sampled group of 29 students.
The student who conducted the survey wanted to test the claim made in the newspaper article by collecting data from a smaller subset of the population.
The sample mean serves as an estimate of the population mean. By calculating the average sleep duration from the sampled students, the student aimed to make an inference about the larger population of college students.
The sample mean provides insight into the sleep habits of the sampled students, but it may or may not accurately reflect the population mean.
In summary, the sample mean of 5.2 hours represents the average sleep duration observed in the sampled group of 29 students,
while the claimed population mean of 6.2 hours represents the average sleep duration stated in the college newspaper article for all college students.

Answers
The correct answer is B. The graph of h is the graph of g vertically shifted up 1 unit.
The correct answer is:
B. The graph of h is the graph of g vertically shifted up 1 unit.
Explanation:
The original function g(x) = x² represents a basic quadratic function, which is a parabola that opens upward and has its vertex at the origin (0, 0).
When we consider the function h(x) = g(x) + 1, we are adding a constant value of 1 to the output (y) values of the function g(x). This results in a vertical shift of the graph of g(x) by 1 unit upward.
In other words, for every x-value, the corresponding y-value of the function h(x) will be 1 unit higher than the corresponding y-value of the function g(x).
Visually, this means that the graph of h(x) will be the same shape as the graph of g(x), but it will be shifted upward by 1 unit. The vertex of the parabola, which was originally at the origin, will now be at (0, 1).
The statement "The graph of h is the graph of g horizontally shifted left 1 unit" (Option A) is incorrect because there is no horizontal shift in this transformation.
The statement "The graph of h is the graph of g vertically shifted down 1 unit" (Option B) is incorrect because the transformation results in a vertical shift upward, not downward.
The statement "The graph of h is the graph of g horizontally shifted right 1 unit" (Option D) is incorrect because there is no horizontal shift in this transformation.
Therefore, the correct answer is B. The graph of h is the graph of g vertically shifted up 1 unit.
