Answer:
C: 3/4x + 3/4 + 3/4 + 2/4x
Step-by-step explanation:
The various expressions simplify to ...
given: 5/4x +6/4
A: 46/4x
B: 2/4x +6/4
C: 5/4x +6/4
D: 2/4x +11
Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive
We are given
P(A)=0.75 [ probability that Nathan is allergic ]
P(T|A)=0.98 [probability of testing positive given Nathan is allergic to Penicillin]
We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)
From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735
The equation (X-4)2 + (y+1)2 = 25 best describes the circle.
