The probability tests to detect the presence of hepatitis B:
P (presence)= 0.97 (true) 0.03 (false)
P (absence)= 0.99 (true) 0.01 (false)
P(infected)=0.0055
P(not infected)= 0.9945
To have an incorrect result:
P[infected and false from P(presence)] + P[not infected and false from P(absence)]
=0.0055*0.03+0.9945*0.01= 0.01011
The answer is<span> 0.01011 </span>

Answer:
Step-by-step explanation:
(5x^3+4x^2)−(6x^2−2x−9)
To find the opposite of 6x^2−2x−9 find the opposite of each term.
5x^3+4x^2−6x^2+2x+9
Combine 4x^2 and 6x^2 to get −2x^2.
5x^3-2x^2+2x+9
Answer: 36.47
Step-by-step explanation:
36.4725 = 36.47
It is rounded to 36.47 because 2 isn't greater or equal to 5, so it turns into 36.47
