Answer:
Part A
The table is filled in based on given data.
- Total = 160
- Snake = 160*0.4 = 64
- No snake = 160 - 64 = 96
- Snake and lizard = 64*0.25 = 16
- Snake no lizard = 64 - 16 = 48
- No snake lizard = 96*0.75 = 72
- No snake no lizard = 96 - 72 = 24
<em>See attached</em>
Part B
- 88 out of 160
- 88/160*100% = 55%
Part C
- 16 out of 160
- 16/160*100% = 10%
Answer:
21a + 9
Simplifying
21a + 9
Reorder the terms:
9 + 21a
Factor out the Greatest Common Factor (GCF), '3'.
3(3 + 7a)
Final result:
3(3 + 7a)

The relative frequency of the marked elks are:
- Male Elk = 7/30
- Female Elk = 4/15
- Adult Elk= 173/450
- Baby Elk = 26/22
<h3>How to determine the relative frequency?</h3>
From the complete question, we have:
- Male = 105
- Female = 120
- Adult = 173
- Baby = 52
- Total = 450
The relative frequency of each is then calculated as:
Male Elk = 105/450
Male Elk = 7/30
Female Elk = 120/450
Female Elk = 4/15
Adult Elk= 173/450
Baby Elk = 52/450
Baby Elk = 26/22
<h3>The number of Elks in the park</h3>
Using the data in (a), we can conclude that:
There are 105 male, 120 female, 173 adult, and 26 baby in the park
