What is the slope of the line that’s contains the points (-2, 5)and (6,-3)?

Step-by-step explanation:

A rental car agency charges $30.00 per day  plus per mile $0.15.

Let x be the number of miles travelled by car

Their total cost = 30 + (0.15x)   ... (1)

Another rental car  agency charges $36.00 per day plus $0.10  per mile

Their total cost = 36 + (0.10x)   ... (2)

Equating (1) and (2), we get

30 + (0.15x) = 36 + (0.10x)

36 - 30 = 0.15x - 0.10x

6 = 0.05x

x = 120 miles

They should travel 120 mils in one day for both rental agencies  to cost the same amount to rent

Final answer:

To find the number of miles that would have to be driven in one day for both rental agencies to cost the same, set up an equation and solve for the number of miles ,  The two rental agencies would cost the same amount to rent if 120 miles were driven in one day.

Explanation:

Let's denote the number of miles driven in one day as x. The total cost for the first rental car agency would be $30.00 + $0.15x, and the total cost for the second agency would be $36.00 + $0.10x. In order for both rental agencies to cost the same amount, we can set up the equation:

$30.00 + $0.15x = $36.00 + $0.10x

Simplifying the equation, we get:

$0.05x = $6.00

Dividing both sides of the equation by $0.05, we find:

x = $120.00

Therefore, the two rental agencies would cost the same amount to rent if 120 miles were driven in one day.

Answer:

The length of side AB is 9 units.

Step-by-step explanation:

In order to find this answer, you must use the distance formula.

[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

x2 = 0

x1 = 0

y2 = -3

y1 = 6

Since both x values are equal to zero, we do not need to plug these into our formula. It will just cancel out. Therefore, just plug in the y values.

[tex]\sqrt{(-3-6)^2}[/tex]

-3 - 6 = -9

(-9)^2 = 81

sqrt(81) = 9 units

Step-by-step explanation:

let y be the value of the gift card and x be the cost of a pair of jeans

The equation for Pablo

y-2x=36    Add 2x to both sides

y=36+2x

The equation for Greg

y-5x=0      Add 5x to both sides

y=5x

Now that we have isolated y in both equations, lets set them equal to each other

36+2x=5x      Subtract 2x from both sides

36=3x            Divide both sides by 3

12=x                x=12, which means that 1 pair of jeans costs $12

Final answer:

The cost of one pair of jeans is $12.

Explanation:

To find the cost of one pair of jeans, we can set up an equation using the information given.

Let's say the cost of one pair of jeans is x. Pablo bought 2 pairs of jeans, so he spent 2x.

He has $36 remaining on his gift card, which means the total amount he spent is the original amount on the gift card minus the remaining balance, which is 2x = original amount - $36.

Greg bought 5 pairs of jeans, so he spent 5x.

He has no money left on his gift card, so the total amount he spent is 5x = original amount.

We can write these two equations:

2x = original amount - $36 ... Equation 1

5x = original amount ... Equation 2

To solve this system of equations, we can substitute Equation 2 into Equation 1:

2x = 5x - $36

3x = $36

x = $12

Therefore, the cost of one pair of jeans is $12.

Concert marketing: The college’s performing arts center wanted to investigate why ticket sales for the upcoming season significantly decreased from last year’s sales. The marketing staff collected data from a survey of community residents. Out of the 110 people surveyed, only 7 received the concert brochure in the mail.

The college's performing arts center should not calculate a confidence interval for the proportion of community residents who received the concert brochure by mail because there is no information on the randomness of the sample, and both n(p-hat) and n(1 minus p-hat) are less than 10.

The college's performing arts center should not calculate a confidence interval for the proportion of all community residents who received the concert brochure by mail based on the collected survey data for a few reasons. First, the sample needs to be random to provide a representative subset of the population, and there is no information provided to confirm that the sample used was random. Secondly, n(p-hat) is not greater than 10, which refers to the number of successes (7 residents received the brochure) not meeting the minimum requirement for the normal approximation to be valid. Lastly, n(1 minus p-hat) is also not greater than 10, indicating that the number of 'failures' (103 residents did not receive the brochure) also does not meet the condition for the central limit theorem to apply. Both the latter points touch upon the requirements for constructing a confidence interval for a proportion which is that np-hat as well as n(1-p-hat) should both be greater than 10 to approximate the binomial distribution with the normal distribution.

Step-by-step explanation:

The simplified result of the given mathematical expression (16 – 1.42 + (–1.5)) is 13.08. This is achieved by following the order of operations for addition and subtraction.

To answer this question, we need to simplify the given expression which includes subtraction and addition of numbers.

The expression is 16 – 1.42 + (–1.5). To simplify, we follow the order of operations, which for this question is just addition and subtraction from left to right.

First, subtract 1.42 from 16, which gives us 14.58.

Next, we need to add -1.5 to 14.58. When we add a negative number, it's the same as subtracting that number. Therefore, 14.58 - 1.5 = 13.08.

The simplified result of 16 – 1.42 + (–1.5) is 13.08.

The probability of getting a tail on the next coin flip remains at 50 percent, regardless of the previous series of outcomes because each coin flip is an independent event.

The question is concerned with the probability of getting a tail after having tossed a coin 100 times and obtaining 67 heads and 33 tails. Despite the past results of these tosses, the coin still has a 50 percent chance of landing on heads or tails on any given flip. This concept is based on the idea that each coin flip is an independent event with its own probability, unaffected by previous outcomes.

To answer the student's question directly, the probability that the next flip results in a tail is still 50 percent because past results do not change the probability of future coin flips. This is supported by the law of large numbers, which states that as the number of trials increases, the relative frequency of results will get closer to the expected probability.

The price of the menu item should be increased by $2.04.

Let's begin by calculating the new cost per package after the price increase. If the original cost per package was $12 and it increased by 17%, we calculate the increase as follows:

Increase = 12 * 0.17 = 2.04

The new cost per package will be:

New cost = 12 + 2.04 = 14.04

To maintain the same dollar profit margin on your menu item, you need to increase the price by the same amount as the cost increase, which is $2.04.

The question involves creating a network representation for multiple-source, multiple-destination distribution, for which nodes represent suppliers and counties, arcs represent the paths with capacities and costs, depicting the logistics of natural gas distribution by Tri-County Utilities, Inc.

Explanation:

The student is asking for a network representation for a supply and distribution problem faced by Tri-County Utilities, Inc. This is related to operations research within the business field, specifically dealing with the optimization of supply chain logistics. The company must distribute natural gas, supplied by Southern Gas and Northwest Gas, to three different counties with varying demand and distribution costs. The aim is to represent this scenario using a network graph that visualizes the routes between the suppliers (Southern Gas and Northwest Gas) and the counties (Hamilton, Butler, and Clermont) along with the distribution costs for each route.

To create a network representation, start with two nodes representing the suppliers and add three additional nodes representing the counties. Then, six directed arcs are drawn from the suppliers to the counties. The capacities of the arcs emanating from Southern Gas should be labeled with 500 units, and those from Northwest Gas should be labeled with 400 units. Likewise, the demand at each county node should be assigned (Hamilton with 400 units, Butler with 200 units, and Clermont with 300 units). Lastly, the costs should be labeled on each of the arcs as provided: from Southern Gas to Hamilton, Butler, and Clermont, the costs are 10, 20, and 15 (in thousands of dollars) respectively, and from Northwest Gas, the costs are 12, 15, and 18 (in thousands of dollars).

Final answer:

The detailed answer explains how to create a network representation for the gas supply problem.

Explanation:

Network Representation:

To develop a network representation of this problem, we can create a graph with nodes representing the counties and the suppliers, and edges representing the distribution costs per unit between them. Here's a simple representation:

Mean of sampling distribution = 25 inches

Standard deviation of sampling distribution = 4 inches

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 25 inches

Standard Deviation, σ = 12 inches

Sample size, n = 9

We are given that the distribution of length of the widgets is a bell shaped distribution that is a normal distribution.

a) Mean of the sampling distribution

The best approximator for the mean of the sampling distribution is the population mean itself.

Thus, we can write:

[tex]\bar{x} = \mu = 25\text{ inches}[/tex]

b) Standard deviation of the sampling distribution

[tex]s = \dfrac{\sigma}{\sqrt{n}} = \dfrac{12}{\sqrt{9}} = 4\text{ inches}[/tex]

Using the Central Limit Theorem, it is found that:

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

The requried total cost of filling her three bottles with olive oil is 2250 x $0.0084 = $18.90.

Simplification is the process of using rules of arithmetic and algebra to eliminate extraneous terms, factors, or operations from an expression, with the objective of obtaining a more manageable, manipulable, or solvable expression. One approach to simplification involves combining like terms, factoring, or utilizing the distributive property when simplifying an algebraic expression.

Here,
Each bottle holds 0.75 liters, which is equivalent to 750 milliliters. So, Jane fills a total of 3 x 750 = 2250 milliliters of olive oil.

The cost of the olive oil is $0.21 for every 25 milliliters, which means the cost per milliliter is $0.21/25 = $0.0084.

It costs Jane $18.90 to fill her three bottles with olive oil, each holding 0.75 liters.

Calculating the Cost of Olive Oil

Jane has three bottles that each hold 0.75 liters. To find out how much it costs her to fill these bottles with olive oil, we need to make a few calculations.

Step-by-Step Calculation:

→ Total volume Jane needs:

= 3 bottles x 0.75 liters

= 2.25 liters

→ Convert liters to milliliters:

= 2.25 liters x 1000

= 2250 milliliters

→ Cost of 25 milliliters of oil: $0.21

→ Number of 25 milliliter increments in 2250 milliliters:

= 2250 / 25

= 90 increments

→ Total cost:

= 90 x $0.21

= $18.90

Therefore, it costs Jane $18.90 to fill her three bottles with olive oil.

Answer:

The 95% confidence interval for the proportion is (0.2824, 0.3672). The upper limit of the interval is higher than 32% = 0.32, which means that the confidence interval does not support this claim.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

[tex]n = 468, \pi = \frac{152}{468} = 0.3248[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3248 - 1.96\sqrt{\frac{0.3248*0.6752}{468}} = 0.2824[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3248 + 1.96\sqrt{\frac{0.3248*0.6752}{468}} = 0.3672[/tex]

The 95% confidence interval for the proportion is (0.2824, 0.3672). The upper limit of the interval is higher than 32% = 0.32, which means that the confidence interval does not support this claim.

In this problem, we apply mathematical concepts related to statistics to determine whether a campaign claim is supported by a survey. The calculation of a 95% confidence interval supports Mayor Waffleskate's claim that no more than 32% of voters want her defeated.

The subject in question refers to confidence intervals and population proportions, both of which are topics in statistics. To answer it, we need to construct a 95% confidence interval for the proportion of voters who wish to see Mayor Waffleskate defeated in the election, based on a sample size of 468 voters, of which 152 express this sentiment.

The first step is to calculate the sample proportion (p), which is the number of 'successes' over the sample size, or in this case 152/468, which equals approximately 0.325.

Next, we apply the formula for the confidence interval for a population proportion, which i

Because the confidence interval (0.278, 0.372) includes the value of 0.32 stated by the Waffleskate campaign, it can be concluded that the claim that no more than 32% of registered voters wish to see her defeated is plausible or supported by this survey at the 95% confidence level.

Answer:

•A c-chart is the appropriate control chart

• c' = 8.5

• Control limits, CL = 8.5

Lower control limits, LCL = 0

Upper control limits, UCL = 17.25

Step-by-step explanation:

A c chart is a quality control chart used for the number of flaws per unit.

Given:

Past inspection data:

Number of units= 100

Total flaws = 850

We now have:

c' = 850/100

= 8.5

Where CL = c' = 8.5

For control limits, we have:

CL = c'

UCL = c' + 3√c'

LCL = c' - 3√c'

The CL stands for the normal control limit, while the UCL and LCL are the upper and lower control limits respectively

Calculating the various control limits we have:

CL = c'

CL = 8.5

UCL = 8.5 + 3√8.5

= 17.25

LCL = 8.5 - 3√8.5

= -0.25

A negative LCL tend to be 0. Therefore,

LCL = 0

The appropriate control chart for the textile mill is the p-chart. The center line is 8.5 flaws per unit, and the control limits can be calculated using the formula LCL = p - Z * sqrt((p(1-p)) / n) and UCL = p + Z * sqrt((p(1-p)) / n).

The appropriate control chart for the textile mill to establish a control procedure on flaws in towels is the p-chart. This chart is used to monitor the proportion of defects in a process. The center line of the p-chart is calculated using the formula p = defects / units inspected. In this case, the center line is 850 / 100 = 8.5 flaws per unit. The control limits are calculated using the formula:

Where p is the proportion of defects, Z is the Z-score corresponding to the desired level of significance (such as 0.06), and n is the number of units inspected. The Z-score can be calculated using a Z-table or a statistical software. The control chart is used to determine if the process is in control or if there are any special causes of variation that need to be addressed.
