The probability that a patient with a negative result is truly HIV-free is 0.999.
<h3>How to find the probability that the negative result is correct?</h3>
To find the probability that confirms that the result of the HIV test is negative, we must take into account the information provided in the information and perform the following mathematical operation.
The probability that No HIV and test positive is:
P = 0.85 * 0.985
P = 0.8372
The probability that HIV and test negative is:
P = 0.15 * 0.003
P = 0.00045
The probability that No HIV and negative test of HIV and negative test is:
P = 0.00045 + 0.8372
P = 0.8377
P = (NOT HIV / Test)
P = 0.8372 / 0.8377
P = 0.999
According to the above, the probability that a patient with a negative result is truly HIV-free is 0.999.

Answer:
it is a 10% increase.
Step-by-step explanation:
3,036 - 2,760 = 276
276/2,760 · 100 = 10%
Answer:
-2265
Step-by-step explanation:
First, we replace x with 20.
![f(20)=-5*20^2-13*20-5](https://tex.z-dn.net/?f=f%2820%29%3D-5%2A20%5E2-13%2A20-5)
Then, we evaluate.
The * stands for multiplication.
![f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265](https://tex.z-dn.net/?f=f%2820%29%3D-5%2A20%5E2-13%2A20-5%5C%5C-5%2A400-260-5%5C%5C-2000-260-5%5C%5C-2265)
Answer:
f^-1(x) = 4x^2 -3 . . . . x ≤ 0
Step-by-step explanation:
Interchange x and y, then solve for y.
x = -1/2√(y+3)
-2x = √(y +3)
4x^2 = y +3
4x^2 -3 = y
Note that the range of the function f(x) is f(x) ≤ 0, so this will be the domain of the inverse function. Then the inverse function is ...
f^-1(x) = 4x^2 -3 . . . . for x ≤ 0
___
The attached graph shows this inverse function is a reflection of the function across the line y=x, as it should be.
35 plus 17.5 equals 52,5 then 52.5 plus 14 equals 66.5
