Answer:
A: 2
B: -1/3
Step-by-step explanation:
A: We are looking for the common ratio between the terms of the sequence, which is essentially what you are multiplying by to get from one term to the next. To find this, we just have to divide the second term by the first term.
-4 / -2 = 2, therefore our common ratio is 2.
We can check this by continuing to multiply the next terms by 2 - -4 x 2 = -8, -8 x 2 = -16, so the pattern works.
B: For B, we will do exactly the same method as before: 3/-9 = -1/3, so our multiplier is -1/3.
To check: 3 x -1/3 = -1, and -1 x -1/3 = 1/3, which both follow our rule.
Hope this helps! Let me know if you have any questions.

See below for the steps to the two-way relative frequency table
<h3>How to create the two-way relative frequency table?</h3>
The table of values is given as:
Communication Gender Male Female Total
Text 150.0 82.0 232.0
Talk 72.0 36.0 108.0
Social Media Apps 28.0 32.0 60.0
Total 250.0 150.0 400.0
Start by dividing each cell by the column total
Male Female Total
Text 150.0/250 = 0.6 82.0/150 = 0.55 232/400 = 0.58
Talk 72.0/250 = 0.288 36.0/150 = 0.24 108/400 = 0.27
Social Media Apps 28.0/250 = 0.112 32.0/150 = 0.21 60/400 = 0.15
Rewrite properly as:
Male Female Total
Text 0.60 0.55 0.58
Talk 0.288 0.24 0.27
Social Media Apps 0.112 0.21 0.15
Total 1 1 1
The above represents the two-way relative frequency table

Answer: Infinite
Odd numbers are of the form 2n+1, where n is an integer
Solving 2n+1 > 19 leads to n > 9. There are infinitely many integers that make the inequality n > 9 to be true.
