Answer:
It could be because it shows trends and shows outliers and all the data in a way that makes sense
Step-by-step explanation:
The relative frequency for the class with lower class limit 31 is 8.57%.
<h3>How to calculate the frequency?</h3>
It should be noted that the lowrr class frequency is 31 in this case.
Therefore, the relative frequency for the class with lower class limit 31 will be:
= 3/(6+4+4+9+3+9) × 100
= 3/35 × 100
= 8.57%
Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.

Answer:
B and C work. A and D do not.
Step-by-step explanation:
This is one of those questions that you have to go through each answer to see what the results are. You don't have to go far to eliminate A and D so let's do that first.
A]
5n + 6
Let n = 1
5(1) + 6
5 + 6= 11
However there is trouble beginning with n = 2
5*2 + 6
10 + 6
16 All you need is one wrong answer and the choice is toast. So A won't work.
================
Try D
6(n - 1)+ 5
n=0
6*(-1) + 5
-6 + 5
- 1
And D has been eliminated with just 1 attempt. n= 2 or n = 1 would be even worse. D is not one of the answers.
=============
B
Let n = 1
6(1) + 5
6 + 5
11 The first term works.
n = 2
6*(2) + 5
12 + 5
17 and n = 2 works as well. Just in case it is hard to believe, let's try n = 3 because so far, everything is fine.
n = 3
6*(3) + 5
18 + 5
23 And this also works. I'll let you deal with n = 4
========
C
n = 0
6(0 + 1) + 5
6*1 + 5
6 + 5
11
n = 1
6(1 + 1) + 5
6*2 + 5
12 + 5
17 which works.
So C is an answer.
A= -81 + square root of 113
