Suppose that 8% of the general population has a disease and that the test for the disease is accurate 70% of the time. what is the probability of testing positive for the disease?

33.2%

Step-by-step explanation:

Suppose that 8% of the general population has a disease. (True positive)

So 92% of the general population has not a disease (false positive)

the test for the disease is accurate 70% of the time (true positive)

so test for the disease is not accurate 30% of the time (false positive)

Now we calculate the probability

8% × 70% + 92% × 30%  

0.08 × 0.7 + 0.92 × 0.3  = 0.332 or 33.2%

The probability of testing positive for the disease is 33.2%

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

i dont know what you want me to answer for this but im guessing 2: 11?
