Answer:
The survey is meaningless because of nonresponse bias.
Step-by-step explanation:
The sample who responded (567) is less than half of Hayden's blog readers (1200). So, in this case, the results were really invalidated, because of the great absence of response, and the survey cannot be taken seriously at least statistically speaking.
567---100
x------35
x≈199 people said No
y= 368 said yes

Depreciation Formula: A = P(1 - rt)
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 36001
<em>r</em> = 16% = 0.16
<em>t</em> = 3
<u>Step 2: Find Cost</u>
- Substitute in variables [Depreciation Formula]: A = 36001(1 - 0.16 · 3)
- (Parenthesis) Multiply: A = 36001(1 - 0.48)
- (Parenthesis) Subtract: A = 36001(0.52)
- Multiply: A = 18720.5
2+2 = 4 therefore four as a fraction would just be four wholes —-> 4/1
