1. Data: is referred to as the collection of facts such as values and measurement. It include but isn't limited to attributes, names, fields and definitions that are being used in a computer database system.
2. Quantitative: this nature of data can be classified as discrete or continuous data. It is typically based on numerical values such as mathematical or statistical analysis of data gathered or collected from various sources e.g questionnaires, polls, surveys etc.
3. Sample: it is a sub-collection of elements coming from a certain population. Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

5. Juan conducted his research using a survey method because he created a questionnaire so as to gather data from his participants.
#1,
The domain is all of the x-values.
The x-values of the set are: 2, 15, 21, 24
Your answer is C.
#2,
Part A)
Yes, the data in the table represents a function because each x-value has exactly one y-value. Also, the function passes the vertical line test.
Part B)
f(x) = 5x - 21
f(11) = 5(11) - 21
f(11) = 55 - 21
f(11) = 34
The table has a y-value of 8, when x = 11.
Therefore, f(x) = 5x - 21 has a greater value than the table when x = 11
Part C)
f(x) = 99
f(x) = 5x - 21
5x - 21 = 99
5x = 120
x = 24
The value of x is 24.

I might be wrong but here you go. Hope this helps!
Answer:
triangles are half a rectangle/square. So thats why you divide by 2. diving by 2 is also multiply by 1/2.
pyramids are in 3 dimensions, so since they are like half, but in three dimensions, you divide by 3, in other words multiply by 1/3.
Step-by-step explanation:
By applying the definition of product between two <em>square</em> matrices, we find that is equal to the matrix . (Correct choice: D)
