Answer:
The relative frequency of mammals in the survey is 30%.
Step-by-step explanation:
Relative frequency is the ratio of the occurrence of a singular event and the total number of outcome
Amphibians Insects Fish Reptiles Birds Mammals
12 30 9 25 22 42
Relative frequency = 
Total number of wildlife animals = 12+ 30 +9 +25+22+42 = 140
Now the relative frequency of mammals in the survey = 
the relative frequency of mammals in the survey =
= 0.3
Converting into percentage , we get
=
= 30 %
Sure, here are what I got for those 2 questions:
16.
