Answer:

Variable A and variable B have a negative linear association.

Step-by-step explanation:

We are asked to find which best describes the association between variable A and variable B.

From the scatter plot we could clearly see that as the value of variable A are increasing the corresponding value of variable B is decreasing.

Also we could see that the points are linear.

Hence, the relationship that best describes variable A and variable B is:

Negative linear Association

Answer:

B) a negative linear association

Step-by-step explanation:

Before answer this question.

Let me explain the types of correlation.

There are three types of correlation: positive, negative, and no correlation.

Positive Correlation: As one variable increases, the dependent variable also increases.

Negative Correlation: As one variable increases, the dependent variable decreases.

No Correlation: There is no apparent relationship between the variables.

In the given scatter plot, As the value of the variable A increases, the value of variable B decreases.

Therefore, it is a negative linear association.

Hope you will understand the concept.

Thank you.

You are a loan officer at the West Elm Savings and Loan. Mr. and Mrs. Brady are in your office to apply for a mortgage loan on a
Leno4ka [110]

Answer:

West Elm Savings and Loan

a) The amount of the down payment is:

= $34,000

b) The amount of the mortgage for which the Bradys are applying is:

= $170,000.

c) The amount of the principal of $136,000 ($170,000 - $34,000) and the interest portion of the monthly payment by the Brady's is:

= $730.32

d. The total amount of interest that will be paid over the life of the loan is:

= $126,915.20

e) Total monthly payment = $994.32

f) No, they will not qualify.

g) The monthly income that would be required to qualify for this size of mortgage payment is:

= $3,977.28

Step-by-step explanation:

a) Data and Calculations:

Market value of mortgage house = $170,000

Required down payment = 1/5 or 20%

a) The amount of the down payment = $34,000 ($170,000 * 20%)

b) The amount of the mortgage for which the Bradys are applying is = $170,000.

c) Interest on the loan = $5.37 for every $1,000

The amount of the principal of $136,000 ($170,000 - $34,000) and interest portion of the monthly payment by the Brady's = $730.32 ($5.37 * $136,000/$1,000)

d. The total amount of interest that will be paid over the life of the loan is:

= $126,915.20 ($262,915.20 - $136,000)

Sum of all periodic payments = $262,915.20 = ($730.32 * 12 * 30)

e) Annual Property tax =         $1,710

Annual Property insurance     1,458

Total additional annual pyts $3,168

Monthly additional costs = $264 ($3,168/12)

Total monthly payment = $994.32 ($730.32 + $264)

f) Bradys' combined monthly income = $3,750

Qualification threshold = $937.50 ($3,750/4)

No, they will not qualify.

g) The monthly income that would be required to qualify for this size of mortgage payment is:

= $3,977.28 ($994.32/0.25)

Solve the system by elimination. − 2 x + 2 y + 3 z = 0 − 2 x − y + z = − 3 2 x + 3 y + 3 z = 5
taurus [48]

Answer:

x=1, y=1, z=0

Step-by-step explanation:

we have

-2x+2y+3z=0 ----> equation A

-2x-y+z=-3  -----> equation B

2x+3y+3z=5 ----> equation C  

adds equation A and equation C

-2x+2y+3z=0\\2x+3y+3z=5\\-------\\2y+3y+3z+3z=0+5

5y+6z=5 -----> equation D

adds equation B and equation C

-2x-y+z=-3\\2x+3y+3z=5\\--------\\-y+3y+z+3z=-3+5

2y+4z=2 -----> equation E

we have the system

5y+6z=5 -----> equation D

2y+4z=2 -----> equation E

Multiply equation E by -1.5 both sides

-1.5(2y+4z)=-1.5(2)

-3y-6z=-3 -----> equation F

adds equation D and equation F

5y+6z=5\\-3y-6z=-3\\---------\\5y-3y=5-3\\2y=2\\y=1

<em>Find the value of z</em>

substitute the value of y in equation E (or substitute in equation D)

2(1)+4z=2

2+4z=2

4z=0

z=0

<em>Find the value of x</em>

substitute the value of y and z in equation A (or equation B or C)

-2x+2(1)+3(0)=0

-2x+2=0

-2x=-2

x=1

therefore

The solution of the system of equations is

x=1, y=1, z=0
