Sauron [17]

Answer:

the probability of an adult getting a NEG result and truly having tuberculosis is 0.0127

Step-by-step explanation:

S = the adult really has tuberculosis.

S' = complement of S = the adult does not has tuberculosis.

POS = the test gives a positive result

P(S)= 0.05

P(POS | S)=0.746

P(NEG | S')= 0.7653

this is an intersection because the "and" word

P(NEG ∩ S) =  P(NEG| S)*P(S)=(1-P(POS | S))*P(S)=(1-0.746)*0.05=0.0127

padilas [110]

Answer:

D

Step-by-step explanation:

The y axis is the vertical axis; the one going up and down.

A reflection means that a point is an equal distance away from its reflector as the basis was.

A was a reflection across the line y=x.

B was a reflection across the x axis with a 90 degree rotation.
