Answer:
1.5
Step-by-step explanation:
Attached to this answer is the diagram of the box plot described in the question, and the means from the plot are calculated thus;
Students; no. of siblings
student 0 2
student 1 4
student 2 7
student 3 5
student 4 2
Total 20
Mean no. of siblings = (total number of siblings) ÷ (total number of students)
Note that number of students here are the once that had at least one sibling, others without siblings are not used in the calculation, hence 5 students (student-0 to student-4) make up total number of students, while the remaining 4 students (student-4 to student-9) are disregarded.
Therefore, mean = 20 ÷ 5 = 4 siblings.
The general term is

(a sub n; n is a subscript)
The first term is a1
The second term is a2
The third term is a3
and so on...
The first term starts at n = 1. We replace the n in

with 1 to get

. A similar thing happens with n = 2 and onward
The domain is therefore the set {1, 2, 3, 4, 5, ...} which is the set of...
* Counting numbers
* Positive Whole numbers
* Natural numbers
Those are three ways to express the same set
We can also say

where n is an integer or whole number
A similar inequality would be

which is effectively the same as idea as the last inequality (n is also an integer or whole number).
Answer:
so it would be (7x-4)+(5x+8) = 160
x=13
Prime numbers can only be divisible by 1 and itself.
2 prime factors of 24= 1 and 2, 1×24=24, 2×12=24
composite have more than 2 factors.
2 composite factors of 24= 4 and 8, 4×6=24 3×8=24
hope this helps.....
