Answer:
11) A=84.7m²
12) A=75.2km²
13) A=28.05ft²
14) A=48yd²
Step-by-step Explanation:
11) A = 1/2(bh)
A = 1/2(14×12.1)
A = 1/2(169.4)
A = 84.7m²
12) A = 1/2(bh)
A = 1/2(16×9.4)
A = 1/2(150.4)
A = 75.2km²
13) A = 1/2(bh)
A = 1/2(5.1×11)
A = 1/2(56.1)
A= 28.05ft²
14) A = 1/2(bh)
A = 1/2(16x6)
A = 1/2(96)
A = 48yd²

From the information, it would be a good idea to rotate the candidate choices A. Yes, to avoid response bias.
<h3>
Response bias</h3>
From the complete question, it should be noted that a good idea to rotate the candidate choices in order to avoid response bias.
When conducting any survey that has multiple choices, the respondents have a tendency to quickly finish up the survey by answering the survey questions quickly.
In this process, this can lead to bias towards the first and last choice. Since the sample of 20 registered voters was surveyed, it is wise to rotate the candidate choices.

24.75 feet was the initial height of the bird. We can use definitions and corresponding addition here:
The word descending is denoted as something or someone that moves or slopes downward. Our equation will look like so, with x representing the initial height of the bird:
x - 8.25 = 16.5 (or in other words, 16.50)
Now that we have our equation set up, we can use inverse operations to solve.
16.50 + 8.25 = 24.75
Since doing addition gave us a total of 24.75, we know that the initial height of the bird is 24.75 feet. To check our work, we can plug this number in for x:
24.75 - 8.25 = 16.50
When calculating, this equation is true. Therefore, the initial height of the bird is 24.75 feet. If you need extra help, do not hesitate to let me know and I will gladly assist you.
