If x=7, determine which lines must be parallel?
1 answer:
Answer: All the lines which are parallel to Y-axis including Y-axis must be parallel to the line x=7.
Explanation:
We can understand it by drawing the line x=7 on the graph.
In the graph, it has shown that x=7 is parallel to Y-axis.
And if we talk about a set of lines x=n, where n is a real number then these lines are parallel to y-axis.
since, we know that if one line is parallel to another line and that line is also parallel to a third line then these three lines must be parallel.
so we can say that, All lines which are parallel to y-axis as well as y-axis are parallel to x=7.

2. Find the five boundary values
Step-by-step explanation:
When drawing a dot, the steps are;
i) The data set (the list of numbers to be presented in the dot plot) are arranged in increasing order from left to right, with thee lowest value on the left and the highest value located at the right of the list
ii) The five boundary values are listed as follows;
The Minimum and Maximum Values
1) The minimum value is the lowest number in the list, which is the first number from the left
2) The maximum value is the final number on the right of the list
3) The Median, Q₂
The median number is the number which divides the data arranged in increasing number, into two equal parts
The First Quartile and Third Quartile
The numbers are divided from the median, such that the Lower half is to the left of the Median, and the Upper half is to the right of median
4) The First Quartile, Q₁ = The median of the Lower half
5) The Third Quartile, Q₂ = The median of the Upper half
iii) The box plot is then drawn with the five boundary values found above
