It is estimated that approximately 10.5% of Americans are afflicted with diabetes. Suppose that a new diagnostic test is being checked for its accuracy. When the test is given to adults over 40 who have diabetes, it marks 95% positive for the disease (this is a correct diagnosis). When the test is given to adults over 40 who do not have diabetes, it marks 3.5% positive for the disease (this is an incorrect diagnosis). Round your final answers to three decimal places. (a) Find the probability that a randomly selected adult over 40 does not have diabetes, and is diagnosed as positive for diabetes by the ne

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

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
