Answer:
10
Step-by-step explanation:
we know that y=sqrt(7), so just plug it into the expression y^2 +3. now we have (sqrt(7))^2 +3, (sqrt(x))^2=x, so (sqrt(7))^2 +3= 7+3=10
That's the same thing as saying 2/3 multiplied by 7/6.
So, the answer is 7/9.
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
