The district manager of four different restaurants wanted to investigate whether the four restaurants differed with respect to customers ordering dessert or not based on family classification (with children or without children). Independent random samples of 100 customers who ordered dessert were selected from each restaurant, and the customers were identified as either being with children or without children. After verifying the conditions for the appropriate hypothesis test, the manager calculated a chi-square test statistic of 6.45 with an associated p-value of 0.092. Based on the p-value and a = 0.05, what conclusion should the manager make regarding the proportion of customers who order dessert at each restaurant and the customers' family classification?
A. There is convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is the same based on family classification.
B. There is convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification.
C. There is not convincing statistical evidence to prove that the proportion of customers who order dessert at each restaurant is not the same based on family classification.
D. There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is the same based on family classification.
E. There is not convincing statistical evidence to suggest that the proportion of customers who order dessert at each restaurant is not the same based on family classification.

marks lawn care company charges a flat fee of $15, plus $9 per half hour for every job. which equation can be used to find the amount Y that marks lawn care company would charge for a lawn job that takes X hours to complete?
A. Y=15x+18
B. Y=18x+15
C. Y=15x+9
D. Y=9x+15

Answers

Answer:

y= 18x + 15

Step-by-step explanation:

If its 9 dollars per hour than it would be 18 per hour. The independent variable is the how long itll take, and the 15 would be without starting. So it results into B) y=18x+15

Answer:

D. (Y=9x+15)

Step-by-step explanation:

This one was pretty easy to find out using common sense, it can be solved via knowing that the only variable being multiplied is 9, so find 9x+15 and there is your answer.

m<P = 48°

m<Q = 132°

Step-by-step explanation:

Given:

m<S = (14x + 6)°

m<R = (5x + 3)°

Required:

m<P, m<Q

Solution:

✔️First, find the value of x

m<S + m<R = 180° (consecutive angles are supplementary)

14x + 6 + 5x + 3 = 180 (substitution)

Collect like terms

19x + 9 = 180

19x = 180 - 9

19x = 171

x = 171/19

x = 9

✔️m<P = m<R (opposite angles are congruent)

m<P = (5x + 3)° (substitution)

Plug in the value of x

m<P = 5*9 + 3

m<P = 48°

✔️m<Q = m<S (opposite angels are congruent)

m<Q = (14x + 6)°

Plug in the value of x

m<Q = 14*9 + 6

m<Q = 132°

Answer: 3 1/3

Step-by-step explanation: You change 8 1/6 to improper fraction which is 49/6 and change 4 5/6 to improper fraction which is 29/6. Next you take 49/6 and subtract 29/6 which is 20/6.After that you simplify 20/6 by divide both sides by 2 which gives you 10/3.Lastly change 10/3 to a mixed number which is 3 1/3.

The relative growth rate for a certain type of bacteria population is 78% per hour. A small culture has formed and in just 5 hours the count shows to be 34,820 bacteria in the culture. What is the initial number of bacteria in the culture? us this formula to solve it and show all work A(t) = Pe^(rt).

Answers

Step-by-step explanation:

A(t)=P(e^(rt))

Insert the values as follows:

The equation for "continual" growth (or decay) is A = Pe^(rt), where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).

34820=P(e^((.78)(5)))

Answer:

r = 16 cm ; l = 34 cm ; LA = 544π cm^2 ; SA = 800π cm^2

Step-by-step explanation:

The volume of the cone can be find with this formula

V = (base area x height)/3

thanks to this formula we can find the base surface

base surface = (V x 3)/height

base surface = (2560π x 3)/30 = 256π cm^2

the formula of the base surface is

base surface = radius^2 x π

so we can find the radius in this way:

radius = √base surface/π

radius = √256π/π = 16 cm

slant height = [tex]\sqrt{radius^2 + height^2}[/tex]

[tex]\sqrt{16^2 + 30^2} =\sqrt{256 + 900} = \sqrt{1156} = 34[/tex] cm

lateral surface = radius x slant height x π = 16 x 34 x π = 544π cm^2

surface area = base area + lateral surface = 256π + 544π =800π cm^2

Creating Your Fashion ProjectOnce you have determined which piece of the ensemble you will be creating, it is time to get down to business and make it. The steps in the process will vary depending on what you have chosen to create, so record the steps of your process as they apply to your project. This can be done either in writing or a video journal. Make sure that you include information about the following steps in the process of creating your item:Defining the ProjectExplain what you will be making. Provide a detailed description of the object and explain how it contributes to the overall outfit that you are creating. It should be visible in the sketches from the brainstorming project, so you should already have a good idea of what the final project will look like.List of Materials and Estimated CostA pen and a calculator on top of a sheet with calculations.Proper estimates from the beginning can make your project go smoothly.Create a list of all of the materials that you will need to create your project and the anticipated budget. You should have already calculated the budget for this item in the planning phase. When planning, you need to use materials that are comparable to those that were the basis for your estimates. If you will need to purchase a pattern to complete your object, that should be included in your materials list so that you can account for that cost. When creating the budget, dont forget additional expenses like sales tax and shipping. Your list of materials should also include the quantities of the material that you need and the equations that you used to calculate them. If you are using fabric, dont forget to allow for seams and other aspects that require additional fabric. In general, when buying supplies it is better to get a little more than you need in case you make a mistake.Actual CostOnce your list is complete, it is time to go shopping. You can get the materials wherever it is most convenient, which might mean a trip to the local craft or fabric store or some online shopping. Once you have gathered all the supplies that you need, record the actual cost of the supplies on your material list and see how well you did. Staying on budget is a challenge for fashion designers because items can become unavailable or costs can unexpectedly go up. You could also luck out and find a sale, bringing your cost down. You will need to keep the whole project on budget, so keep a record of whether you are under budget, on budget, or over budget, which means that you will have to cut some costs from elsewhere in your project.Making Your ItemNow that you have planned your item and gathered your materials, it is time to get to work! As you create the item, keep either a written or video journal of the steps in the process describing how you constructed it. If you keep a written journal, include photographs of the steps in the process. If there are skills that you are bringing to your project, be sure to highlight them and explain the techniques that you are employing.ConclusionWhen you have concluded the project, be sure to take a picture of your item. Your final entry for this section of the journal should be a description of this project and an overview of the process required to create it. If there were glitches in production (as there almost always are), explain what happened, what you would do differently next time, and how you worked around it for this project. If you had to go back and buy additional materials, make sure that you make a note of that and adjust your budget accordingly. Also include what the most rewarding part of the project was and where you were most frustrated when working on it.
