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.

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?
Answers
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

How do you find the area under a curve?
Answers
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.

Sum the terms (x - 2) for x = 2 to 5 then square the result
[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²
= ( 0 + 1 + 2 + 3 )²

Answer:

Step-by-step explanation:
The Rational Root Theorem says that any rational root has
1. a numerator that is a factor of the constant term
2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)
Numerator: [tex]\pm 1[/tex]
Denominator: [tex]\pm 2[/tex]
That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]
Try them both by plugging them into the polynomial.
[tex]2\left(\frac{1}{2}\right)^3 + 3\left(\frac{1}{2}\right)^2 -1= \frac{1}{4}+\frac{3}{4}-1 =0[/tex]
