Answer:0.789

Step-by-step explanation:

  20 % person smokes and 80 % don't smoke

Probability that a smoker gets lung cancer=15%

Probability that a non smoker gets lung cancer is =1%

Thus

Probability if a person is diagnosed with cancer he/she is a smoker

P=\frac{Smoker}{Given he gets cancer}

P=\frac{0.2\times 0.15}{0.8\times 0.01+0.2\times 0.15}

P=\frac{0.03}{0.038}=0.789

dexar [7]

Answer:

2h-2=92 and h-2=92-h.

Step-by-step explanation:

Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.

The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.

 

Combining like terms we would have the first correct choice, 2h-2=92.

Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.

What ones are functions and which are not pls help
Fantom [35]
Functions: the chart with number values, the dot graph, and the middle graph on the right

Not functions: the top graph on the left with the vertical line, the graph with the circle, and the bottom right graph

Any graph that doesn’t pass the vertical line test is not a function. You can do this by starting at the top of the graph and drawing a line straight down through what you are testing. If you pass through the line or circle more than once it is not a function.
If you look at the number values if the x value repeats more than once it is not a function.
