Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell five cars; nineteen generally sell six cars; twelve generally sell seven cars; nine generally sell eight cars; eleven generally sell nine cars. Calculate the following. (Round your answer to two decimal places.)Data Value (# cars) Frequency Relative Frequency Cumulative Relative Frequency

Answers

Answer 1

Answer:

Step-by-step explanation:

From the information given:

We can compute the required calculations into a table as shown below.

[tex]\mathbf{Data \ value }[/tex]       [tex]\mathbf{ Frequency }[/tex] [tex]\mathbf{Relative \ frequency}[/tex]   [tex]\mathbf{Cumulative \ relative }[/tex]

                                                                                              [tex]\mathbf{Frequency}[/tex]

5                                     14                14/65 = 0.22                           14  

6                                     19                19/65 = 0.29               19+14 = 33

7                                      12                12/65 = 0.19               33+12 = 45

8                                       9                 9/65 = 0.14               45 + 9 = 54

9                                     11                11/65  = 0.17              54 + 11 = 65

                                        65

Note: that the relative frequency is determined by  dividing each value in the frequency by the total of the frequency.

Corey, Billy, and Shea own a house repair and update business. The number of hours that each person spent painting and doing repair work on the same house is listed below.
• Corey: 4.25 hours
• Billy: 7.75 hours
• Shea: 10.5 hours
They earned a total of $1,100 for the job and put 25% of the money earned in an account for future expenses. If they divide the money proportionally based on the number of hours each worked, how much money did Shea receive?
A.$385
B.$412.50
C.$413.33
D.$641.77
Please show ALL of your work.

Answers

Answer:

The correct answer is A. $385.

Step-by-step explanation:

Since Corey, Billy, and Shea own a house repair and update business, and the number of hours that each person spent painting and doing repair work on the same house is listed below.

• Corey: 4.25 hours

• Billy: 7.75 hours

• Shea: 10.5 hours

And since they earned a total of $ 1,100 for the job and put 25% of the money earned in an account for future expenses, to determine how much money Shea received if they divided the money proportionally based on the number of hours each worked is owed perform the following calculation:

1100 x 0.75 = 825

10.5 + 7.75 + 4.25 = 22.5

22.5 = 100

10.5 = X

10.5 x 100 / 22.5 = X

1050 / 22.5 = X

46.666 = X

825 x 0.4666 = X

384.99 = X

Therefore, Shea received $385.

rachel is 1.35 m tall her friend pita is 179 cm tall who is taller and by how much give your answer in centimeters

Answers

Answer:

Pita, by 44 cm

Step-by-step explanation:

1,35 m = 135 cm

179 cm > 135 cm, so Pita is taller than Rachael

The difference is:

179 cm - 135 cm = 44 cm

solve for the missing angle measurement

Answers

The total sum of angles in a trapezium is 360°.

x + 80° + 75° + 105° = 360°

x + 260° = 360°

x = 360° - 260°

x = 100°

The missing angle measurement is 100°.

A utility company charges $0.12 per kilowatt-hour for energy a customer uses.They give a credit of $0.0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves.A customer has a charge of $82.04 and a credit of -$4.10 on this mouth bill. How many kilowatt-hours did they use (Nearest-whole number?

Answers

Answer:

2,324.

Step-by-step explanation:

Given that a utility company charges $ 0.12 per kilowatt-hour for energy a customer uses, and they give a credit of $ 0.0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves, if a customer has a charge of $ 82.04 and a credit of - $ 4.10 on this mouth bill, to determine how many kilowatt-hours did they use the following calculation must be performed:

(82.04 / 0.12) + (-4.10 / - 0.0025) = X

683,666 + 1,640 = X

2,323.66 = X

Thus, rounded to the nearest whole number, users used 2,324 kilowatts per hour.

Sarah lives in Ruthin and works in Oswestry for 5 days a week. each day she travel to and from work. Work how many miles does she commute a week​

Answers

Answer: 330 miles

Step-by-step explanation:

The distance provided for the question is:

Wrexham

18 Ruthin

21 12 Cornwen

15 33 23 Oswestry

What this means is that Ruthin and Oswestry are 33 miles apart.

Each day, Jane travels back and forth for a total of:

= 33 * 2

= 66 miles

In 5 days she would have travelled:

= 5 * 66

= 330 miles

The profit function P(x) is the revenue function R(x) (how much it takes in) minus the cost function C(x) (how much it spends). In economic models, one typically assumes that a company wants to maximize its profit, or at least make a profit!
Part A: Answer the following questions about the cost function C(2) and the revenue function R(x).
1. What is the domain and range of C (x)?
2. What is the meaning of the slope and intercept of C(x)?
3. At what production level 2 will the company receive the most revenue?
Part B. Answer the following questions about the profit function P(x).
4. Assuming that the company sells all that it produces, what is the profit function?
5. Why is finding the range of P(x) important?
6. The company can choose to produce either 60 or 70 items. What is their profit for each case, and which level of production should they choose?
7. Can you explain, from our model, why the company makes less profit when producing 10 more units?

Answers

Solution :

a).

1. The domain of C(x)

   [tex]$x \in [0, \infty)$[/tex]

Range of c(x) is [tex]$[0, \infty)$[/tex]

Since the negative value do not make any sense.

2. C(x) =  Ax + b

  Intercept here denotes the fixed cost (that is when x = 0)

  The slope indicates the marginal cost (that is increase in cost per unit of quantity)

3. Revenue is maximum marginal revenue = 0

(that is when at the top of the parabola)

4. Profit = R(x) -C(x)

5. Range of P(x) is important so that we have the idea in mind about the maximum loss and the maximum profit for a particular quantity.

Answers

Answer: $4.40

Step-by-step explanation:

Trust me did the assignment

Answer:

$26.40.

Step-by-step explanation:

Find 20% of 22.

20% x 22 = 22/5 = 4 2/5 = 4.40.

So the tip costs 4.40, so let's add that to 22 to find the total cost. 4.40+22=26.40, so the entire meal costs: $26.40.
