What is the difference between quantitative data and qualitative data? in what situations could the number 42 be considered qualitative data? what are the characteristics of a relational database?
The number 42 could be qualitative if it is a designation instead of a measurement, count, or calculation.
Qualitative data describes qualities or characteristics. It is collected using questionnaires, interviews, or observation, and frequently appears in narrative form. For example, it could be notes taken during a focus group on the quality of the food at Cafe Mac, or responses from an open-ended questionnaire. Qualitative data may be difficult to precisely measure and analyze. The data may be in the form of descriptive words that can be examined for patterns or meaning, sometimes through the use of coding. Coding allows the researcher to categorize qualitative data to identify themes that correspond with the research questions and to perform quantitative analysis.
Quantitative data is numbers-based, countable, or measurable. Quantitative data is numeric, the result of a measurement, count, or some other mathematical calculation. Qualitative data is descriptive. The number 42 could be qualitative if it is a designation instead of a measurement, count, or calculation.
The seven characteristics that define relational database are:
Accuracy and Precision
Legitimacy and Validity
Reliability and Consistency
Timeliness and Relevance
Completeness and Comprehensiveness
Availability and Accessibility
Granularity and Uniqueness

Continuation of Qn on part ii)
Answer:
Step-by-step explanation:
below is a sequence of numbers:
0.5, 3, 5.5, 8, …
Calculate:
(a) the 8th term,
Answer: ______________
(b) the 100th term,
Answer: ______________
(c) which term has a value of 148.
Answer:
a) 18
b)248
c) 58
Step-by-step explanation:
The formula is:
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1)d
[tex]a_{n}[/tex] Is the number at the n term
[tex]a_{1}[/tex] Is the first number in the sequence
n Is the number for the term
d is the common difference. How much is added each time in the sequence. In this case, 2.5
Put in the numbers that you know and solve for the unknown.
A:
[tex]a_{8}[/tex] = 0.5 + (8 -1)(2.5)
[tex]a_{8}[/tex] = 0.5 +(7)(2.5)
[tex]a_{8}[/tex] = 0.5 + 17.5
[tex]a_{8}[/tex] = 18
B:
We follow the same pattern, but we are now looking for [tex]a_{100}[/tex].
[tex]a_{100}[/tex] = 0.5 + (100-1)(2.5)
[tex]a_{100}[/tex] = 0.5 + 247.5
[tex]a_{100}[/tex] = 248
C:
This time we know the value of the number in the sequence, we do not know which term it is.
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1)d Put in what we know
148 = 0.5 + (n -1)2.5 Distribute the 2.5
148 = 0.5 + 2.5n - 2.5 Combine like terms
148 = 3 + 2.5n Subtract 3 from both sides of the equation
145 = 2.5n Divide both sides by 2.5
58 = n

Angle DEF is an inscribed angle on a circle, and m
O 48°
O 96°
O 132°
O 24°
∠24°
What is an inscribed angle in a circle?
Inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc.
given that intercepted arc = ∠48°
The intercepted arc is the arc that is inside the inscribed angle and whose endpoints are on the angle.
If the intercepted arc is twice the size of the inscribed angle, then the inscribed angle is half the size of the intercepted arc. So if the intercepted arc is 48 degrees, the inscribed angle is 48 / 2 = 24 degrees.

A 19-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is three inches more than five times the length of the first piecefind the lengths of the pieces. 3 + 5x
Using algebraic expressions and equations to solve this problem, a 19- inch piece of steel is cut into three pieces measuring 2 inches, 4 inches, and 13 inches.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
If the second piece is twice as long as the first piece, we can write this as an algebraic expression "2x" where x is the length of the first piece.
If the third piece is three inches more than five times the length of the first piece, we can write this as an algebraic expression "3 + 5x" where x is the length of the first piece.
If the three pieces were cut from a single piece of steel 19-inches long, we can write the equation for the sum using the algebraic expressions.
let x = length of first piece
2x = length of second piece
3 + 5x = length of third piece
x + 2x + 3 + 5x = 19 inches
Solving for x,
8x = 19 -3
8x = 16
x = 2 inches
length of first piece = 2 inches
Substitute the value of x in the expressions for the second and third piece.
length of second piece = 2x
length of second piece = 2(2)
length of second piece = 4 inches
length of third piece = 3 + 5x
length of third piece = 3 + 5(2)
length of third piece = 3 + 10
length of third piece = 13 inches

a. 26 or more rides
b. 24 or more rides
c. 25 or more rides
d. 27 or more rides
Number of train rides to make the frequent-rider pass a better deal than standard train tickets is 26 or more rides.
As given,
Cost of standard train ticket = 3 per ride
Price of frequent rider pass= 18.75 each month
Cost of ticket using rider pass = 2.25 per ride

9990000 are 7 digit phone number combinations are possible.
what is permutation and combination?
In mathematics, there are two additional methods for dividing a set of components into subsets: combination and permutation. The elements of the subset may be mixed in any order. The subset's elements are listed in a permutation in a certain order.Find every 7-digit phone number combination that exists first.
Given that the digit can be repeated, a total of 107 combinations are available.
The next step is to identify all conceivable combination of seven-digit numbers that begin with "911."
since it begins with "911" Therefore, there are just 4 digits left. 104 combinations are thus feasible in total.
The total number of potential combinations that begin with "911" is then subtracted.
We finally get
10⁷ - 10⁴
= ( 10³ - 1 ) × 10⁴
= 999 × 10⁴
