The ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.
What is proportional?
A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)
To find the cost of hiring a taxi to drive 1, 2, 3, and 4 miles, we can use the formula:
C = 4 + 1.25m
For m = 1, we have:
C = 4 + 1.25(1) = 5.25
For m = 2, we have:
C = 4 + 1.25(2) = 6.5
For m = 3, we have:
C = 4 + 1.25(3) = 7.75
For m = 4, we have:
C = 4 + 1.25(4) = 9
So the table of costs for driving 1, 2, 3, and 4 miles is:
Miles (m) Cost (C)
1 5.25
2 6.5
3 7.75
4 9
To determine whether the cost of the taxi is proportional to the number of miles driven, we can check whether the ratios of cost to distance are equal. If they are, then the cost is proportional to the number of miles driven.
Let's check the ratios:
C(1)/1 = 5.25/1 = 5.25
C(2)/2 = 6.5/2 = 3.25
C(3)/3 = 7.75/3 = 2.58333...
C(4)/4 = 9/4 = 2.25
Hence, the ratios are not all equal, we can conclude that the cost of the taxi is not proportional to the number of miles driven.

Which equation is represented by the graph?
y = 2x2 + 1
y = 2x2 − 1
y = 1/2x^2 + 1
y = x2 − 1
Answer:
y = x^2 − 1
Step-by-step explanation:
By the look of each graph, it looks like y = x2 − 1 is the answer.

Who has the most money based on the table below?
A marathon is 26.2 miles long. Jarrod is running a marathon and has completed 17.75 miles. How
many more miles to the finish line?
Answer:
Jarron has 8.45 more miles to get to the finish line.
Step-by-step explanation:
All we have to do is subtract the total number of miles by the number of miles Jarron has completed.
So: 26.20 - 17.75 = 8.45
26.2 - 17.75 = 8.45
All you need is subtraction because you are finding what is left.
You can find 8.45 by using a calculator or solving in your head, it would just take longer.

The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (Time.com). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars.
Private Colleges
53.8 42.2 44.0 34.3 44.0
31.6 45.8 38.8 50.5 42.0
Public Colleges
20.3 22.0 28.2 15.6 24.1 28.5
22.8 25.8 18.5 25.6 14.4 21.8
(a) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for private colleges. (Round the standard deviation to two decimal places.)
(b) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for public colleges. (Round the standard deviation to two decimal places.)
(c) What is the point estimate (in thousand dollars) of the difference between the two population means? (Use Private − Public.)
We estimate that the mean annual cost to attend private colleges is $ more than the mean annual cost to attend public college
(d) Develop a 95% confidence interval (in thousand dollars) of the difference between the mean annual cost of attending private and public colleges. (Use Private − Public. Round your answers to one decimal place.)
A 20-foot string of lights will be attached to the top of a 12-foot pole for a holiday display. How far from the base of the pole should the end of the string of lights be anchored?

–x + 5y = 14; (–5, –2)
A. y = 5^x – 27
B. y = -1/5x – 27
C. y = -1/5x – 15
D. y = -5^x – 27
Answer:
D. y = -5^x – 27
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula y − y 1 = m ( x − x 1 ) to find the line perpendicular to − x + 5 y = 14 .
y = − 5 x − 27 PERPENDICULAAR

Benny the Barber (see Question 1) is considering the addition of a second chair. Customers would be selected for a haircut on a FCFS basis from those waiting. Benny has assumed that both barbers would take an average of 20 minutes to give a haircut, and that business would remain unchanged with customers arriving at a rate of two per hour. Find the following information to help Benny decide if a second chair should be added: Part (a): The average number of customers waiting. Part (b): The average time a customer waits. Part (c): The average time a customer is in the shop.
According to the information presented, Benny should decide not to add a second chair because the average number of clients waiting is 1 (very low), the average waiting time for a client is 10 minutes (very low), and the average time a customer is in the store is 20 minutes (very low).
According to the information, an average of 2 clients arrive at the hairdresser for every hour (60 min) and each cut takes a maximum of 20 minutes. Therefore, the hairdresser would have an average of 40 minutes busy and 20 minutes free for each hour.
Additionally, customers who must wait do not have to spend a long time waiting in the store because the maximum waiting time is 10 minutes (in the case that both customers arrive at the same time).
Below is a graph where the information of both cases is compared (with an additional chair and without an additional chair) and it is inferred that an additional chair is not necessary because the number of clients waiting and the waiting time is not high.
