The mean is the average. To find this, we add up all the numbers, then divide by the number of numbers there are.
12+23+17+20+14+14+18+16+17+18+18= 187
187/11=17
The mean is 17.
The median is the middle number. To find this, line up all the numbers, smallest to largest.
12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23
You then cross off numbers from both sides, until you have 1 number remaining.
Your median is 17.
The mode is the number that occurs most frequently.
Your mode is 18.

the correct answer is yes
because yes.
Answer: an = 9n + 23
Step-by-step explanation:
The formula for determining the nth term of an arithmetic sequence is expressed as
an = a1 + (n - 1)d
Where
a1 represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 32
d = 9
Therefore, the equation or rule for the given arithmetic sequence would be
an = 32 + (n - 1)9
Expanding the brackets, it becomes
an = 32 + 9n - 9
an = 9n + 32 - 9
an = 9n + 23
This will never be proportional since the line in the graph never goes through the origin
Not proportional
