Many service companies collect data via a follow-up survey of their customers. For example, to ascertain customer sentiment, Delta Air Lines sends an e-mail to customers immediately following a flight. Among other questions, Delta asks:
How likely are you to recommend Delta Air Lines to others?
The possible responses are:
1. Definitely will
2. Probably Will
3. May or May Not
4. Probably Will Not
5. Definitely Will Not
Required:
a. Are the data collected by Delta in this example quantitative or categorical?
b. What measurement scale is used?
Answer:
The answer is "Categorical and Ordinal scale"
Step-by-step explanation:
Categorical factors affect data types that can be grouped. This analysis is the examination of data in which the answer variables are grouped in a series of reciprocal classifications, like the age group or even the unordered groups of eye colors.
An ordinal chart is a form of the category with such a specific order or scale. It is the 2nd assessment level that provides the ordering and order of data, without really measure the extent of variability. The first of the four measuring scales is the ordinal scale of listening.

What is the solution of system of equations
Answer:
i don't know if it is correct or not, sorry if i were mistaken
The value of x and y for the given system of equations is 1 and 6 respectively.
What is system of equations?
A system of equations is a collection of two or more equations with a same set of unknown variables.
What is solution to the system of equation?A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously.
What is substitution method?The substitution method is a method to solve simultaneous linear equations. In which the value of one variable from one equation is substituted in the other equation.
According to the given question
we have a system of equations
[tex]6x + 3y = 24..(i)[/tex]
and, [tex]3x -4y = -21..(ii)[/tex]
From equation (i)
[tex]6x + 3y = 24[/tex]
⇒ [tex]2x + y = 8[/tex]
⇒ [tex]y = 8-2x[/tex]
Substitute the value of y in equation (ii)
⇒[tex]3x - 4(8-2x)=-21[/tex]
⇒[tex]3x-32+8x =-21[/tex]
⇒[tex]11x = 32-21[/tex]
⇒[tex]11x = 11[/tex]
⇒ [tex]x =1[/tex]
Substitute, x = 1 in either the equations (i) and (ii)
⇒[tex]3(1)-4y =-21[/tex]
⇒[tex]3 -4y=-21[/tex]
⇒[tex]-4y = -21-3[/tex]
⇒-4y = -24
⇒[tex]y =6[/tex]
Hence, the value of x and y for the given system of equations is 1 and 6 respectively.

A farmer finds that if she plants 55 trees per acre, each tree will yield 25 bushels of fruit. She estimates that for each additional tree planted per acre, the yield of each tree will decrease by 4 bushels. How many trees should she plant per acre to maximize her harvest
Answer:
31 trees per acre will maximize the harvest
Step-by-step explanation:
Given
[tex]Plant \to 55[/tex] trees/acre
[tex]Yield \to 25[/tex] bushels
[tex]x \to trees[/tex]
Required
Number of trees to maximize harvest
From the question, we understand that:
Yield will decrease by 4 i.e. 25 - 4x
For every additional tree planted, i.e. 55 + x
So, the function is:
[tex]F(x) = (25- 4x)*(55+x)[/tex]
Open bracket
[tex]F(x) = 25 * 55 -4x * 55 + 25 * x -4x*x[/tex]
[tex]F(x) = 1375 - 220x + 25x -4x^2[/tex]
[tex]F(x) = 1375 -195x -4x^2[/tex]
Rewrite as:
[tex]F(x) = -4x^2 -195x +1375[/tex]
The maximum of a quadratic function is calculated as:
[tex]Max = -\frac{b}{2a}[/tex]
In the above equation:
[tex]a = -4; b =-195; c = 1375[/tex]
So:
[tex]x = -\frac{-195}{2 * -4}[/tex]
[tex]x = -\frac{195}{8}[/tex]
[tex]x = -24.375[/tex]
Recall that the number of trees to be planted is: 55 + x
So, we have:
[tex]Trees = 55+x[/tex]
[tex]Trees = 55-24.375[/tex]
[tex]Trees = 30.625[/tex]
Approximate
[tex]Trees = 31[/tex]
The Fighting Hens' record has improved every year. The 2016 team won 3
more games than the 2015 team, and the 2017 team won 2 more games
than the 2016 team. If the 2017 team won 20 games, how many did the 2015
team win?
Answer:
15
Step-by-step explanation:
just calculate backwards
20 -2 -3
Answer:
The answer would be 15.
Step-by-step explanation:
I agree with the previous answer, in these cases you just calculate backward.
You start out with 20, then it states 2017 team won 2 more games, so you subtract 2. So now we know the 2016 team won 18 games.
Next we subtract 3 to get how many wins the 2015 team got. 18 - 3 is 15.
The answer would be 15.

Answer:
[tex]\frac{1}{324632}[/tex] probability of picking the winning combination
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Since the order is not important, the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
The correct five numbers from a set of 5. So
[tex]D = C_{5,5} = \frac{5!}{5!0!} = 1[/tex]
Total outcomes:
Five numbers from a set of 35. So
[tex]T = C_{35,5} = \frac{35!}{5!30!} = 324632[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{324632}[/tex]

B: x ≤ 5
C: 5 ≤ x ≤ 31/3
D: There are no solutions
E: All values of x are solutions
Answer:
B: x≤5
Step-by-step explanation:
Hi there!
We're given two inequalities; 3x−8≤23 and −4x+26≥6
We need to find the values of x that make BOTH of the inequalities true (which is the intersection of the two inequality graphs)
First, let's solve for x in both of them
taking the first inequality:
3x−8≤23
add 8 to both sides
3x≤31
divide by 3
x≤31/3
now solve for x in −4x+26≥6
subtract 26 from both sides
-4x≥-20
divide both sides by -4 and remember to FLIP the inequality sign since we have a negative number
x≤5
now let's graph these two inequalities to find the intersection, and that is below with the answer

The sum of two integers is 33. The larger is 6 more than twice the smaller. Find the two
integers.
Answer:
24 and 9
Step-by-step explanation:
Hi there!
Let x be equal to the larger integer.
Let y be equal to the smaller integer.
1) Construct equations
[tex]x+y=33[/tex] (The sum of two integers is 33)[tex]x=6+2y[/tex] (The larger is 6 more than twice the smaller)2) Solve for one of the integer
Isolate x in the first equation
[tex]x+y=33\\x=33-y[/tex]
Plug the first equation into the second
[tex]33-y=6+2y[/tex]
Combine like terms
[tex]33-6=2y+y\\27=3y\\9=y[/tex]
Therefore, the smaller integer is 9.
3) Solve for the other integer
[tex]x+y=33[/tex]
Plug in y (9)
[tex]x+9=33\\x=33-9\\x=24[/tex]
Therefore, the larger integer is 24.
I hope this helps!

What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
The similarity of triangles on the other hand is when the corresponding angles are equal but the corresponding sides are not equal but they have the same common ratio.
From the given diagram a quadrilateral ABCD is given,
Line segment AC divides quadrilateral ABCD into two triangles namely
ABC and ADC, and both have a common side AC.
m∠BAC ≅ m∠DAC and m∠BCA ≅ m∠DAC.
Therefore, Triangle ABC and ADC are congruent by ASA, with two angles and a side included between them.

PREVIOUS ANSWERS MY NOTES Calls to a customer service center last on average 2.8 minutes with a standard deviation of 1.4 minutes. An operator in the call center is required to answer 75 calls each day. Assume the call times are independent. What is the expected total amount of time in minutes the operator will spend on the calls each day
Answer:
The expected total amount of time in minutes the operator will spend on the calls each day is of 210 minutes.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
n-values of a normal variable:
For the sum of a sample of n values, the mean is of [tex]M = n\mu[/tex] and the standard deviation is of [tex]s = \sigma\sqrt{n}[/tex]
Average 2.8 minutes
This means that [tex]\mu = 2.8[/tex]
75 calls each day.
This means that [tex]n = 75[/tex]
What is the expected total amount of time in minutes the operator will spend on the calls each day?
[tex]M = n\mu = 75(2.8) = 210[/tex]
The expected total amount of time in minutes the operator will spend on the calls each day is of 210 minutes.
