What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
The rule is given in the question, as follows:
y is 3 less than x
For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.
For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).
Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).
The table for the given rule can be completed as follows:

1. Is the following question a statistical question? " During which month did your family take a vacation?"
2. What is the statistical variable represented by the following question, and is it categorical or quantitative? "How many TV sets are owned by families?"
Answers
Problem 1
Answer: No, it is not a statistical question
Explanation:
This is because the question is directed at a specific family, your family in particular. If the surveyor is only asking one person, then there's no need for statistics since a sample isn't formed.
If the question is posed to many people taking a survey, then it would be statistical in nature. However, no further context or clarification is given, so I'll assume that the question is directed at one person, or one family, only. I think your teacher would say "During which month do families take vacation?" to be more general and involve statistics.
==============================================================
Problem 2
Answer: The statistical variable is the number of tv sets owned, and this variable is quantitative
Explanation:
The variable is what we want to figure out, and it's random in nature. Hence the name "random variable". It takes on nonnegative whole numbers 0,1,2,3,... so we can see the data set is discrete. The term "discrete" in math means that there aren't infinitely many numbers between two values. For example, if we pick 2 and 5, we can see the values 3,4 are between them and that's it. Contrast this with a continuous data set and there are infinitely many real numbers between 2 and 5 (eg: 2.78912 and 3.412)
While it might be tempting to think of a discrete number set as finite, that's not entirely true. We have infinitely many nonnegative whole numbers to work with. Though of course, there's a realistic limit that we arrive to and someone having 277 televisions is completely out of the ordinary, if not impossible.
The data variable "Number of TV sets owned" is not only discrete, but it's also ordinal, interval and ratio data as well. Here's a breakdown of what I mean
Ordinal = The data values 0,1,2,3,... can be ordered and it makes sense to do so. Usually the order is from smallest to largest.Interval = Gaps between any two values make sense. So going back to 2 and 5, the gap here is 3. Meaning that if family A has 2 tvs and family B has 5 tvs, then we can say that family B has 3 more tvs compared to family A. Such a statement is valid which means interval data applies.Ratio = Not only can we subtract, but we can also divide. If family A has 2 tvs and family B has 6 tvs, then we can see that the second family has 6/2 = 3 times as many televisions compared to the first family. Again, you have to ask if such a statement makes sense for this type of data to apply.Since we have many terms apply to this, it sometimes helps to pick just one and try to have it describe the others implicitly. So we go for ratio data since that encapsulates interval and ordinal data types as well. If something is ratio, then automatically it must be ordinal and interval. Division depends on the numbers being well ordered, and that gaps between values make sense and are consistent.
To recap, the data type is quantitative, discrete, and we have a ratio scale.
The variable "number of tv sets owned" is not categorical since the choices to pick from 0,1,2,3,... aren't names; instead they are numbers in which we can perform math operations on and have it make sense. So that's why we go for quantitative data instead of categorical. If it asked "what brand of TV are owned by families?", then the categories of the various brand names would be the answer choices, and lead to categorical data.
Side note: categorical data is always qualitative

Enter your answer in the box.
Answers
Answer:
The artist can make six batches of orange paint and it remains one cup of yellow paint
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of red paint for one batch of orange paint = 1/3 of a cup
Amount of yellow paint for one batch of orange paint= 1/3 of a cup
Amount of red paint available = 2 cups
Amount of yellow paint available = 3 cups
2. How many batches of orange paint can she make?
2 cups of red paint = 6/3 = 6 batches of orange paint
3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint
The artist can make six batches of orange paint and it remains one cup of yellow paint

Step-by-step explanation:

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given three data sets.
All the samples have 10 data points.
Number of data points = 10
Mean of sample 1 = 9.1
Mean of sample 2 = 9.4
Mean of sample 3 = 8.9
We can see that the mean of the three samples is so close to each other.
So the data is reliable.
Hence the option is A.

plzz help me solve this question i need correct question i will mark you as a brainliest and I will give 5.0 rating anf thanks if ur answer will be correct
Answers
Answer:
I. p = 7
II. 17 litres
Step-by-step explanation:
I. Determination of the value of p
Mean = 17.7
p =.?
Let the number of litre be L
Let the number of motorist be M
Mean = summation LM / summation M
Summation of LM = (16×11) + (17×10) + (18×p) + (19×4) + (20×8)
= 176 + 170 + 18p + 76 + 160
= 582 + 18p
summation M = 11 + 10 + P + 4 + 8
= 33 + p
Mean = summation LM / summation M
17.7 = 582 + 18p / 33 + p
Cross multiply
17.7(33 + p) = 582 + 18p
584.1 + 17.7p = 582 + 18p
Collect like terms
584.1 – 582 = 18p – 17.7p
2.1 = 0.3p
Divide both side by 0.3
p = 2.1 / 0.3
p = 7
II. Determination of the median number of litre.
Let the number of motorist be M (i.e the frequency)
summation M = 11 + 10 + P + 4 + 8
p = 7
summation M = 11 + 10 + 7 + 4 + 8
summation M = 40
The median is the middle term i.e
Median = (summation M / 2)ᵀʰ motorist
Median = (40 / 2)ᵀʰ motorist
Median = 20ᵀʰ motorist
Considering the table in the question above, the 20ᵀʰ motorist has 17 litres.
Therefore, the median number of litres is 17 litres.
