A) Choosing a stratified random sample might be preferable to an SRS because;

Stratified random sampling would divide the population into stratas but the

SRS would not do so. The strata would be the type of room namely those

with water view and those with golf view.

B) The reason why a cluster sample would be a simpler option is because;

It will divide the population into multiple clusters that makes it easier to

work with unlike the SRS that generalizes. The clusters would be each of

the 30 floors.

We are told that the manager wanted to select 120 rooms and carry out a survey on each registered guest by asking how satisfied they were with the hotel. He decided to use a sampling method called SRS which means Simple Random Sampling.

Simple random sampling is defined as a sampling method where individuals or objects are selected randomly from a population thereby given each person or object an equal chance of selection.

A) Stratified Random sampling is a method of sampling that divides the population into smaller groups known as objects/stata. In this case Stratified random sampling would be preferred to SRS because the hotel rooms are divided into two types namely those that can view the water and those that can view the golf course and as such the Stratified random sampling would divide the population but the SRS would not do so.

B) Cluster sampling is when the population is divided into multiple groups known for assessment. The reason why it would be a simpler option is because there are 30 floors and they can be classified as clusters and surveyed per floor.

Answer:

slope = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x - 4y = 7 ( subtract 3x from both sides )

- 4y = - 3x + 7 ( divide terms by - 4 )

y = [tex]\frac{3}{4}[/tex] x - [tex]\frac{7}{4}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{3}{4}[/tex]

Answer:

1: less

2: lesser

Step-by-step explanation:

We can complete the statement as -

Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.

The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.

We have a inequality statement that compares the magnitude of two lowest balances as -

|−300| > |−100|

For a number [x], such that [x] < 0, the absolute value would be -

v[a] = -x

So -

for x = |- 300| = 300

and

for x = |- 100| = 100

On comparing -

300 > 100

We can complete the statement as -

Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.

Therefore, we can complete the statement as -

Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.

Answer:

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

Step-by-step explanation:

18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )

= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term

= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )

= (3² - x²)(2x + 1)

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

Answer:

The normal cost would be $11.50

The normal cost for an individual will be $11.50 per person.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Angie and her companions are making a beeline for the Ice sheet Levels snow park. They intend to buy the Glacial mass gathering bundle, which costs $76 for 8 individuals.

The cost of individuals will be given as,

⇒ $76 / 8

⇒ $9.50

That's $2 less per person than the normal cost for an individual. Then the normal cost is given as,

⇒ $9.50 + $2

⇒ $11.50

The typical expense for a singular will be $11.50 per individual.

The required amount that Jonathan needs to pay to move in the apartment is $3472.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Jonathan is signing a lease for an apartment that rents for $1240/month.

According to the condition, he must pay the first and last months’ rent and a security deposit equal to 80% of his monthly rent.

So,
Total amount to pay = sum of the first and last month rent + 80% of a month rent
Total amount to pay = 1240 + 1240 + 80% of 1240
Total amount to pay = 2480 + 0.80[1240] = $3472

Thus, the required amount that Jonathan needs to pay to move in the apartment is $3472.

Answer:

Step-by-step explanation:

Given:

Convert parsec to km:

Find the radius of Segue 2 in parsecs:

>= means greater than or equal to

<= means less than or equal to

---------------------------------------------

Part A

The graph of y >= -3x+3 will have a solid boundary line and the shading will be above the boundary line.

The boundary line y = -3x+3 has a negative slope so it moves down as you read it from left to right. It goes through the points (0,3) and (1,0)

--------------

The graph of y < (3/2)x - 6 will have a dashed or dotted boundary line. The shading is below the boundary.

The graph y = (3/2)x-6 goes through the two points (0,-6) and (2,-3)

--------------

If you graph both y >= -3x+3 and y < (3/2)x - 6 together, you get what you see in the attached image. This solution shaded region is the result of the overlapping prior shaded regions.  

---------------------------------------------

Part B

Plug (x,y) = (-6,3) into each inequality to see if we get a true inequality or not

For the first inequality we have

y >= -3x+3

3 >= -3*(-6)+3

3 >= 18+3

3 >= 21

which is false. The value 3 is not larger or equal to 21. So right off the bat we know that (-6,3) is NOT a solution. It is NOT in the solution region.

Let's check the other inequality just for the sake of completeness

y < (3/2)x - 6

3 < (3/2)*(-6) - 6

3 < -9 - 6

3 < -15

this is also false. The value -15 is smaller than 3, since it is to the left of 3

We're given more evidence that (-6,3) is NOT in the solution area. It is outside of both shaded areas.  

Answer:

Step-by-step explanation:

Length = 4 * width

L = 4 * w

70 = Perimeter = 2*Length + 2* width = 2(4w) + 2w = 8w + 2w = 10w

so w=7 --> length is 28.  Note that perimeter is 28+28+7+7 = 56 + 14 = 70

Then the area is 28 x 7 = 196 square inches

Answer:

107

Step-by-step explanation:

Angle 1

When a line is passes through a straight line, the two angles must equal 180 degrees.  Since you know the one angle is 81, then angle 1 is 180 - 81 or

99 degrees.

Angle 2

You can determine the angle that is opposite of the 91 angle.  These two angles must add up to 180.  So the angle to the right of 91 must be 89.

89 + 91 = 180

You were told lines c and d are parallel.  Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.

Angle 3

Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.

So angle 3 is equal to the angle marked as 81 degrees.

Angle 1 + Angle 2 - Angle 3 = 107

-2 both sidea

-42=k(14)

divide by 14 both sides

k=-3

k = -3

Step-by-step explanation:

y = kx + 2 through the point a(14, -40)

Subtitute…

y = kx + 2

-40 = k(14) + 2

-40 = 14k + 2

-40 - 2 = 14k
