Let 1st integer be x and next consecutive be x+1
1/2•x + 1/5•(x+1) = 10
x/2 + x/5 + 1/5 = 10
-1/5 -1/5
x/2 + x/5 = 49/5
(x/2)•5/5 + (x/5)•2/2 = 49/5
5x/10 + 2x/10 = 49/5
7x/10 = 49/5
•10 •10
7x = 98
÷7 ÷7
x = 14 --> 1st integer
x+1 = 14+1 = 15 --> next consecutive integer
There is evidence of non-response bias in the survey results because only a fraction of the people that were mailed responded.
<h3>What is a survey?</h3>
A survey is a type of research which seeks to obtain information from a specific group of people called respondents. The research is normally in form of a questionnaire the reflects the honest opinion of the respondent.
From the result of the survey, it is possible to conclude that there is evidence of non-response bias in the survey results because only a fraction of the people that were mailed responded.

The rate of change of a given function is given by f'(x)=dy/dx
given that the function is:
f(x)=12+2^(-2x)
f'(x)=2*(-2)e^(-2x)
f'(x)=-4e^(-2x)
the relative rate of change will be the ratio of the derivative to the original function:
f'(x)/f(x)
=(12+2^(-2x))/(-4e^(-2x))
