Answer:
0.03
Step-by-step explanation:
Percentage of americans with diabetes = 10.5% = 0.105
Percentage of americans without diabetes = 89.5% = 0.895
Adults over 40 with diabetes tested positive = 95% = 0.95
Adults over 40 with diabetes tested negative = 5% = 0.05
Adults over 40 without diabetes tested positive = 3.5% = 0.035
Adults over 40 without diabetes tested negative = 96.5% = 0.965
The probability of selecting an adult over 40 without diabetes but positive diagnosis;
= 0.895 * 0.035
= 0.031325
= 0.03

3x2 + -6x + c = 0
Reorder the terms:
c + -6x + 3x2 = 0
Solving
c + -6x + 3x2 = 0
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '6x' to each side of the equation.
c + -6x + 6x + 3x2 = 0 + 6x
Combine like terms: -6x + 6x = 0
c + 0 + 3x2 = 0 + 6x
c + 3x2 = 0 + 6x
Remove the zero:
c + 3x2 = 6x
Add '-3x2' to each side of the equation.
c + 3x2 + -3x2 = 6x + -3x2
Combine like terms: 3x2 + -3x2 = 0
c + 0 = 6x + -3x2
c = 6x + -3x2
Simplifying
c = 6x + -3x<span>2</span></span>
