Need help with a simple problem 2^x=3^x+1

KiRa [710]

For $x\ \textgreater \ 0$ , $2^x\ \textless \ 3^x$ , all the more $2^x\ \textless \ 3^x+1$ , therefore no solution.

For $x=0$ , we have $2^0=3^0+1 \Rightarrow 1=1+1 \Rightarrow 1=2$ . Obviously that' false.

For $x\ \textless \ 0$ both $2^x$ and $3^x$ , where $2^x\ \textgreater \ 3^x$ , belong to the range $(0,1)$ , then $3^x+1$ belong to the range $(1,2)$ .
Those ranges don't have a common part, therefore, again, no solution.

So, the equation $2^x=3^x+1$ doesn't have a solution.

It is estimated that approximately 10.5% of Americans are afflicted with diabetes. Suppose that a new diagnostic test is being c

Alla [95]

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
