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).
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.

What is the total surface area of a pyramid with a square base with sides of 12 cm, where the faces
have a slant height of 15 cm?
15 cm
On this side.
A
= 0.3333333
12 cm
O A 144 cm?
OB 234 cm
OC 360 cm
OD 504 cm?
Answer: 504
Step-by-step explanation:
Area: 4 triangles + square
Triangle area = 1/2 x b x h
Square = side x side
4(1/2 x 12x 15) + 12x12
= 504
How do you find the area under a curve?
Answer:
The area under a curve between two points can be found by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. Areas under the x-axis will come out negative and areas above the x-axis will be positive.

Answer:
Step-by-step explanation:
Problem 1
g(-23) = 3
g(0) = 5
2 = g(10)
1 = g(34)
Problem 2
No, because g(x) = f(-x). For g(x) to inverse of f(x), g(f(x)) = x
Problem 3
tan(50) = 1.19
Height of statue = 250*1.19 - 150
= 147.9 ft
Problem 4
cosθ = 9/12
θ = 41.41 deg.
Answer:
Step-by-step explanation:
g(x) is inverse of f(x)
so g(f(x))=x
g(-23)=3
g(0)=5
g(10)=2
g((34)=1
no, it is an inverse
4 inverse fn, g(r(x))=x
but here g(x)=r(-x)
so g(r(x))=r(-r(x)) n NOT =x
pedestal + statue = 250*tan(50degree) = 297.94
statue ht = 297.94-150 = 147.94 ft
cos(theta) = 9/12
theta = 41.41 deg.

Name the 4Ps of marketing.
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.
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
Omar, Hala and Lujain got paid a total of $240 for cleaning neighborhood cars. They split the money in the ratio of 5: 9: 10. How much money did Omar earn?
Answer:
Total amount Omar earn = $120
Step-by-step explanation:
Given:
Total amount Omar, Hala and Lujain got paid = $240
Ratio of money Omar, Hala and Lujain got paid = 5:9:10
Find:
Total amount Omar earn
Computation:
Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]
Total amount Omar earn = [240][5 / (5+9+10)]
Total amount Omar earn = [240][5 / (24)]
Total amount Omar earn = [24][5]
Total amount Omar earn = $120
