Answer:

Product – Attributes of an organization or offering within this segment include delivery system design, technology, quality, services provided and their availability.

Price – This silo of the marketing mix includes costs to users/supporters, payment periods, arrangements and terms. Note: Some have also argued “costs” are more than dollars … a full cost analysis should include emotional (for those seeking greater purpose, advancements, victory), sacrificial (for people giving time, energy, focus) and relational (what does one’s association with an organization do for their relationships … will people think more or less of them).

Place – An often-overlooked part of the marketing mix, this “P” covers strategy and executional elements surrounding service distribution channels, coverage, locations, logistics and e-services.

Promotion – Likely the most known aspect of the marketing mix, this piece considers strategies and tactics related to advertising, logo/identity and promotions. But it also covers development/fundraising, communications, events and public relations as they are all tools to be considered and deployed as part of the greater marketing and branding strategy.

Question 7
A cylindrical water tank carries a volume of 150 L when it is full. The water tank has a base surface
with a diameter of 140 cm. What is the height of the water tank? Round your answer to three decimal
digits.​

Answers

Answer:

Volume of a Cylinder:

In geometry, a cylinder is a three-dimensional shape with a circular base, a circular top and straight sides. It is the solid figure that you get when you rotate a rectangle about one of its sides. In most cases when we talk about the volume of a cylinder, we are talking about how much liquid it can hold.

The strictly correct way of saying it is "the volume surrounded by a cylinder" - the amount of liquid it holds. But many textbooks simply tell "the volume of a cylinder" to mean the same thing.

Remember that the radius and the height must be in the same units - convert them if necessary.

The resulting volume will be in those cubic units. So if the height and radius are both in centimeters, then the volume will be in cubic centimeters.

The volume of a cylinder is found by multiplying the area of its top or base by its height and is defined as: V = π· r2· h

Example 1: A cylindrical water storage tank has an inside base radius of 7m and depth of 11 m. Find the capacity of the tank in kiloliters (1kl = 1m3).

Solution:

Base radius: r = 7 m

Height: h = 11 m

The water storage tank is in the shape of the cylinder. So using the volume of cylinder formula we can find the volume of it.

V = π· r2· h

V = π· 72· 11

V = 1692.46 m3 = 1692.46 kl

Example 2: Find the volume of a cylinder whose base radius is 6 cm and height is 4 cm.

Solution:

Base radius: r = 6 cm

Height: h = 4 cm

V = π· r2· h

V = 3.14· 62· 4

V = 452.16 cm3

Example 3: If the capacity of a cylindrical tank is 1848 m3 and the diameter of its base is 14 m, find the depth of the tank.

Solution:

Let the depth of the tank be h metres. Then we have:

V = π· r2· h

h = V / π· r2

h = 12 m

Example 4: A conical vessel, whose internal radius and height is 20cm and 50 cm respectively, is full of liquid. Find the height of the liquid if it is put into a cylinder whose base radius is 10 cm.

Solution:

The volume of the vessel is:

V = π ∙ r2 ∙ h / 3

V = π · 202· 50 / 3

V = 20944 cm3

The volume of the liquid is the same no matter it is in the vessel or in the cylinder, therefore we have:

V1 = V2, where V1 is the volume of the vessel and V2 is the volume determined using the formula for a cylinder.

20944 = π · 102 · h

Thus:

h = 20944 / (π · 102)

h = 66.67 cm

Example 5: Find the volume of a right circular cylinder whose curved surface area is 2640 cm2

And the circumference of its base is 66 cm.

Solution:

To begin with we need to determine the base radius using the formula for circular perimeter (circumference).

P = 2 · π ·r

r = P /(2 · π) = 66 / (2 · π) = 10.50 cm

Now we will find the height of the cylinder using the formula for surface area of a cylinder.

SA = P · h

h = SA / P = 2640 / 66 = 40 cm

The volume of the cylinder is therefore:

V = π· r2· h

V = π· 10.502· 40

A company would like to advertise that their new fishing line has an average breaking strength greater than 15 kilograms. The lines breaking strength is known to vary in the population on average 2.8 kilograms. To test the breaking strength of their new product the company takes a random sample of 50 lines, the average strength measure is 16.1 kilograms. What type of procedure should they use to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.

Answers

Answer:

A right-tailed test should be used to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.

Step-by-step explanation:

Type of procedure:

We want to test if the breaking strength is greater than a value, which means that the type of procedure used to solve this question is a right-tailed test, which is when we find the probability of having a mean higher than the sample mean found.

Other types of procedures:

Not related to this question speficially, but to similar problems.

To test if a measure is less than another measure, the procedure used is a left-tailed test.

To test if a measure is different from another measure, the procedure used is a two-tailed test.

The owner of Maumee Ford-Volvo wants to study the relationship between the age of a car and its selling price. Listed below is a random sample of 12 used cars sold at the dealership during the last year.

Car Age (years) Selling Price ($000) Car Age (years) Selling Price ($000)
1 9 8.1 7 8 7.6
2 7 6 8 11 8
3 11 3.6 9 10 8
4 12 4 10 12 6
5 8 5 11 6 8.6
6 7 10 12 6 8


Required:
a. Determine the regression equation.
b. Estimate the selling price of a 10-year-old car (in $000).
c. Interpret the regression equation (in dollars).

Answers

Answer:

ŷ = -0.47876X + 11.17724

$6.4

Step-by-step explanation:

Given the data :

Car Age (years) Selling Price ($000) Car Age (years) Selling Price ($000)

1 9 8.1 7 8 7.6

2 7 6 8 11 8

3 11 3.6 9 10 8

4 12 4 10 12 6

5 8 5 11 6 8.6

6 7 10 12 6 8

The estimated regression equation using a linear regression calculator is :

y = -0.47876X + 11.17724

With - 0.47876 being the slope ; and 11.17724 being the intercept

y = predicted variable (price of car) ; x = predictor variable (Age of car)

Selling price of a 10 year old car : x = 10

ŷ = -0.47876(10) + 11.17724

Price = 6.38964

About 6.4(000) dollars ($6,400)

According to the regression equation : The starting price of cars is about $11.18 (intercept) with the proved of cars declining by a value of $0.479(negative slope value) each year.

According to the Oxnard College Student Success Committee report in the previous year, we believe that 18% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class. For this year, you would like to obtain a new sample to estimate the proportiton of all Oxnard students who struggle in their classes because they don't study enough outside of the classrooms. You would like to be 99% confident that your estimate is within 5% of the true population proportion. How large of a sample size is required

Answers

Answer:

A sample size of 392 is required.

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].

The margin of error is:

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

18% of students struggle in their classes because they don't spend more than 8 hours studying independently outside of a 4-unit class.

This means that [tex]\pi = 0.18[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

You would like to be 99% confident that your estimate is within 5% of the true population proportion. How large of a sample size is required?

A sample size of n is required.

n is found when M = 0.05. So

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

[tex]0.05 = 2.575\sqrt{\frac{0.18*0.82}{n}}[/tex]

[tex]0.05\sqrt{n} = 2.575\sqrt{0.18*0.82}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.18*0.82}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575\sqrt{0.18*0.82}}{0.05})^2[/tex]

[tex]n = 391.5[/tex]

Rounding up:

A sample size of 392 is required.
