Question:
<em>A research center poll showed that 78% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief? </em>
<em>The probability that someone does not believe that it is morally wrong to not report all income on tax returns is . (Type an integer or a decimal.)</em>
Answer:

Step-by-step explanation:
Given
Let p represent the given proportion
p = 78%
Required
Determine the probability that someone holds a contrary belief
Start by converting the given proportion to decimal



In probability, the sum of opposite probability is equal to 1
Represent the probability that someone holds a contrary belief with q
So;

Make q the subject of formula

Substitute 0.78 for p


<em>Hence, the probability that someone does not believe is 0.22</em>
The answer is: " 8 " .

Explanation:
________________________________
Let "x" represent the "original number".
2(x - 3) = 6 + (1/2)x ; Solve for "x" ;
______________________________________
Multiple the ENTIRE EQUATION (both sides) by "2" ; to get rid of the fraction:
2*{2(x - 3) = 6 + (1/2)x} ;
to get:
4(x - 3) = 12 + x ;
___________________________
Let us expand the "left-hand side" of the equation:
_____________________________________________
Note the "distributive property of multiplication" :
_____________________________________________
a(b - c) = ab - ac ;
a(b +c) = ab + ac ;
______________________________________________
So; "4(x - 3)" = 4*x - 4*3 = 4x - 12 ;
______________________________________________
Rewrite the equation:
_______________________________________________
4x - 12 = 12 + x ;
Subtract "x" from EACH side of the equation; and Add "12" to EACH SIDE OF THE EQUATION;
______________________________________________
4x - 12 - x + 12 = 12 + x - x + 12 ;
to get:
______________________________________________
3x = 24 ;
_____________________________________________
Now, divide EACH side of the equation by "3" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_____________________________________________
3x/3 = 24/3 ;
_____________________________________________
x = 8 .
