In 2005 the U.S. Census Bureau reported that 68.9% of American families owned their homes. Census data reveal that the ownership rate in one small city is much lower. The city council is debating a plan to offer tax breaks to first-time home buyers in order to encourage people to become homeowners. They decide to adopt the plan on a 2-year trial basis and use the data they collect to make a decision about continuing the tax breaks. Since this plan costs the city tax revenues, they will continue to use it only if there is strong evidence that the rate of home ownership is increasing. a) In words, what will their hypotheses be

Answer:

36.9°

Step-by-step explanation:

As shown in the diagram attached,

θ is the acute angle formed at the intersection of the diagonals of the rectangle.

From the diagram,

tan(θ/2) = 10/30

tan(θ/2) = 1/3

θ/2 = tan⁻¹(1/3)

θ/2 = 18.43

Therefore,

θ = 18.43×2

θ = 36.87

θ = 36.9°

Hence the acute angle formed is 36.9°

Answer:

n – 1,400 = 7,437

Step-by-step explanation:

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

Let us represent :

Weight of the mother elephant = x

Weight of the baby elephant = y

A baby elephant weighs 1,400 pounds, which is 7,437 pounds less than her mother.

y = x - 7437 pounds

Hence,

1400 pounds = x - 7437 pounds

The weight of the mother elephant =

x = 1400 pounds + 7437 pounds

Therefore, the equation that expresses the weight of the mother where, the weight of the mother = n is:

n – 1,400 = 7,437

Answer:

<1 and <5

Step-by-step explanation:

<5 and <2 are vertically opposite. They are not complementary but they are equal

<3 is a right angle. <2 is an acute angle. They are not complementary.

<3 and <6 are both right angles. They are also vertically opposite angles and are are therefore equal. They are not complementary.

Answer: <1 and <5

<1 and 2 are complementary. <2 and <5 are vertically opposite and equal.

<1 and <5 are complementary.

Answer:

Step-by-step explanation:

parell lines have same slopes

perpendical line slope product is -1

Answer:

5

Step-by-step explanation:

(5x + 10) + 55 = 90

5x + 10 + 55 = 90

5x + 65 = 90

5x + 65 - 65 = 90 - 65 (the 65 crosses off)

5x = 25

5x/5 = 25/5

x = 5

Answer:

the cost for the large popcorn and the small drink is $4 and $3 respectively

Step-by-step explanation:

The computation of the cost for the large popcorn and the small drink is shown below:

Let us assume the cost of the large popcorn be x

ANd, the small drink cost be y

Now as per the question

2x + 4y = $20

2x + 2y = $14

Now subtract equation 2 from equation 1

2y = $6

y = $3

Now for x it is

2x + 12 = $20

2x = $8

x = $4

Hence, the cost for the large popcorn and the small drink is $4 and $3 respectively

Answer:

GHK = 28

Step-by-step explanation:

Angle GHK and angle JHI are vertical angles

Vertical angles are congruent so

Because angle JHI = 28 then angle GHK also equals 28

Answer:

The GHK is 28

Step-by-step explanation:

Answer:

Here is the step: Area of triangle = 1/2 (height x base) = 1/2 (9 x 18) = 81

Step-by-step explanation:

Then the Area of the rectangular = 12 x 18 = 216

So the  total Area of the figure is = 81 + 216 = 297

Answer:

x = 3

Step-by-step explanation:

Using the geometric mean for altitude:

x + 9 = √18 *  8 = √144,

x + 9 = 12,

x = 3

Solution: x = 3

Answer:

29.6 - 0.2 = 29.4

29.4 divided by 24 = 1.225 km

Answer:

1.225

Step-by-step explanation:

24/29.4=1.225

Answer: -36

Step-by-step explanation:

13, 6, -1

to get from 13 to 6 and 6 to -1, you would subtract by 7 so keep subtracting by 7 until you get 8 different terms

13, 6, -1, -8, -15, -22, -29, -36

the eighth term would be -36

i hope that makes sense

Answer:

Hey mate....

Step-by-step explanation:

This is ur answer......

Hint: We will multiply and divide a same number greater than 2 to both the given numbers, say 3 as 3>2. When we will multiply and divide by 3, the numbers 2 and 3 will be equivalent to 63 and 93. Now, we can easily write two rational numbers between 2 and 3.

Hope it helps!

mark me brainliest plz......

Follow me! ;)

Answer:

x= -1, y= 5

Step-by-step explanation:

Please see the attached picture for the full solution.

Matrix A is called the coefficient matrix. This means that its elements are the coefficient of x and y. In matrix X, write the unknown variables. Then write the constants in matrix B.

Theorem:

[tex]{A}^{ - 1} A = I[/tex]

☆ I is an identity matrix and can be treated as 1 when multiplying.

[tex] {A}^{ - 1} = \frac{1}{ |A| } adj(A)[/tex]

☆ [tex] |A|[/tex] is the determinant of A

☆ adj(A) is the adjoint of matrix A
