3h+18 is the correct answer:)
Answer:
what do I need to do to answer
Step-by-step explanation:
A non-response bias is when subjects are selected to participate in a survey but some choose not to respond. This would lead to a portion of the population being misrepresented leading to inaccurate results. For example, those who returned the survey might be more likely to do something than those who did not complete the survey.
Answer:
a
because 1 1/2 * 1 1/2 *1 = 2 1/4
I'll do the first two to get you started
===============================================
Problem 1
A = 3 = starting value
B = 10 = ending value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (10-3)/3 ] * 100%
C = (7/3) * 100%
C = 2.3333333 * 100%
C = 233.33333%
C = 233.3%
The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.
<h3>Answer: 233.3% increase</h3>
===============================================
Problem 2
A = 9 = start value
B = 20 = end value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (20-9)/9 ] * 100%
C = (11/9)*100%
C = 1.2222222222*100%
C = 122.22222222%
C = 122.2%
<h3>Answer: 122.2% increase</h3>
