A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property. The manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view. What type of sample was obtained
Answers
Answer: Stratified Random Sample
Step-by-step explanation: The type of sampling exemplified by the manager's selection is Stratified Random Sampling whereby the entire population (guests in the hotel) are divided into subpopulation(independent subgroups) called strata; those with rooms facing the golf course and those facing the water view. The sample this have two strata based on the view in which the rooms are facing. Taking a simple random samples from each sub group of the entire population may lead to less bias since the customers may experience different level of satisfaction based on this condition.
The type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.
What is sampling?
Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population.
Now here, the manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property.
So, here cluster sampling would be preferred because there are 30 floors and they can be classified as clusters and surveyed per floor.
Thus, the type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.

In ΔUVW, \overline{UW} UW is extended through point W to point X, \text{m}\angle UVW = (3x+4)^{\circ}m∠UVW=(3x+4) ∘ , \text{m}\angle VWX = (8x-12)^{\circ}m∠VWX=(8x−12) ∘ , and \text{m}\angle WUV = (x+20)^{\circ}m∠WUV=(x+20) ∘ . What is the value of x?X?
Answers
Answer:
The value of x is 9°
Step-by-step explanation:
The given parameters are;
ΔUVW with side UW extended to X
m∠UVW = (3x + 4)°
m∠VWX = (8x -12)°
m∠WUV = (x + 20)°
We have that m∠UVW + m∠WUV + m∠VWU = 180° (Sum of the interior angles of a triangle theorem)
∴ m∠VWU = 180° - (m∠UVW + m∠WUV)
Also we have that m∠VWX and m∠VWU are supplementary angles, (The sum of angles on a straight line)
∴ m∠VWX + m∠VWU = 180° (Definition of supplementary angles)
m∠VWU = 180° - m∠VWX
∴ m∠VWX = (m∠UVW + m∠WUV)
Substituting the values, gives;
(8x -12)° = (3x + 4)° + (x + 20)°
8x - 3x - x = 4 + 20 + 12
4x = 36
x = 36/4 = 9
x = 9°.

Which expression would be easier to simplify if you used the commutative property to change the order of the numbers? A. 30+(-12)+70 B. -10 +(-20) + 1/2 C. 60+40+(-25)
Answers
Answer: A
Step-by-step explanation:
Ok, some that we always try to do in math is to look for "nice" numbers.
The nice numbers are numbers that are easy to work with.
Examples of these are numbers like 10, 100, etc.
suppose the next example:
9 + 3 + 1 + 7
That may seem a long addition, but we can rearange the numbers in such a way to get:
(9 + 1) + ( 3 + 7) = 10 + 10 = 20
This is specially useful when doing mental calculus.
In the given options, we have:
A) 30 + (-12) + 70
Doing it straightforward, we must:
Subtract 12 from 30, which will give us a not nice number.
30 - 12 = 18
And now add 70 to that:
18 + 70 = 88.
Now, we could use the commutative properety and get:
30 + (-12) + 70 = 30 + 70 + (-12)
in this way, in the first addition we get to 100, and then we subtract 12 units.
(30 + 70) + (-12) = 100 - 12 = 88.
Then the correct option is A.
Logan is 8 years older than 4 times the age of his nephew. Logan is 32 years old. How old is his nephew?
Answers
Answer:
the nephew is 6.
Step-by-step explanation:
4n+8=32
n=6
Answer:
6 years old
Step-by-step explanation:
We can create an equation for Logan's age using the given information. Let's set the age of Logan's nephew to be x. The expression for Logan's age will look like:
Logan = 4x + 8This expression tells us that Logan is 4 times the age of his nephew, plus 8 years.
Now, we are given Logan's actual age: 32. We can substitute this value into "Logan" in our equation for Logan's age.
32 = 4x + 8To finalize this problem we will solve for "x" to find the age of Logan's nephew.
Subtract 8 from both sides of the equation.
24 = 4xDivide both sides of the equation by 4.
6 = x x = 6Therefore, we know that Logan's nephew is 6 years old.

Find the zero of the function f(x)=4x^2-12x+9
Answers
Answer:
x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
f(x) = 4x² - 12x + 9
To obtain the zero let f(x) = 0 , that is
4x² - 12x + 9 = 0 ← in standard form
(2x - 3)² = 0 ← in factored form , then
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
The zero of the function f (x) = 4x² - 12x + 9 will be 3/2.
What is Quadratic polynomial?
A polynomial which has highest power 2 is called a quadratic polynomial.
Given that;
The function is;
f (x) = 4x² - 12x + 9
Now, To find zero of the function we equate the function to zero.
We get;
f (x) = 4x² - 12x + 9
4x² - 12x + 9 = 0
Solve the function by quadratic formula we get;
x = - (-12) ± √12² - 4 × 4 × 9 / 2 × 4
x = 12 ± √144 - 144 / 8
x = 12 ± 0 / 8
x = 12/8
x = 3/2
Thus, The zero of the function f (x) = 4x² - 12x + 9 will be 3/2.

Giving the following information:
Monthly deposit= $35
Number of periods= (65 - 23)*12= 504 months
Interest rate= 0.08/12= 0.0067
To calculate the future value, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i

Dave and Steve are 700 meters apart from each other on a straight path. Both start walking toward each other and meet each other after 7 minutes. Dave covers a distance of x meters in one minute, which is 20 meters less than the distance Steve covers in a minute. Which of these equations can be used to find the rate at which Steve and Dave walk?
Answers
Options :
A. 7x -(7x+20)=700
B.7x + 7(x+20) =700
C. 7x + (7x-20)=700
D.7x - 7(x-20) =700
Answer:
B.) 7x + 7(x+20) =700
Step-by-step explanation:
Given that :
Dave and Steven are 700m apart
They start walking towards each other and meet after 7 minutes
Distance covered by Dave per minute = x
Distance covered by Steven per minute = x + 20
rate = distance per minute
Dave's rate = x / minute
Steven's rate = (x + 20) / minute
Distance = rate * time
Distance covered by DAVE :
X /min * 7 = 7x
Distance covered by STEVEN :
(x + 20) * 7
= 7(x + 20)
Hence, the sum of distances covered by both Dave and Steven should add up to the total distance :
7x + 7(x + 20) = 700

Susan has a collection of 50 nickels and dimes. If the number of nickels is four times the number of dimes, how many nickels and how many dimes does she have?
Answers
Answer:
Susan has:
40 nickels & 10 dimes
Step-by-step explanation:
Since she has a total of 50 nickles and dimes I knew that it could be separated into 5 sets of 10. Knowing that 4(10) is equal to 40+10 is equal to 50, I used the 10 for the amount of dimes and used 40 for the amount of nickles. So the nickles (40) are 4 times the dimes (10). We can prove this by multiplying the dimes by 4 (4(10)) and you get 40 and add on the 10 you get the total amount of 50.
I hope this helps:)
There are 40 nickels and 10 Dimes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let N be the number of nickels
Let D be the number of dimes
Susan has a collection of 50 nickels and dimes.
N + D =50...(1)
Number of nickels is four times the number of dimes
N = 4D
Substitute N in equation 1
4D+D=50
5D=50
Divide both sides by 5
D=10
Now put D value in equation 1
N+10=50
Subtract 10 from both sides
N=40
Hence, there are 40 nickels and 10 Dimes.

Step-by-step explanation:
The rate of change for a vertical line is undefined.
The rate of change for a HORIZONTAL line is 0
Theoretically, the rate of change for a vertical line is not zero it is undefined.
What is the average rate of change?It is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.
Zero rates of change refer to a quantity that does not fluctuate over time.
But bear in mind these two separate circumstances: Horizontal lines have a slope of 0 since the vertical change is 0.
As 0 cannot be split into any integer, there is no slope for vertical lines since there is no horizontal change.
Because of this, the rate of change for a vertical line is not zero but rather is unknown.
