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

Answer:
y = 2x - 1
Step-by-step explanation:
(4,7) (2,3)
slope = (7-3)/(4-2) = 4/2 = 2
y = 2x + c
when x=4 , y=7
7 = 2(4) + c
c = 7-8 = -1
y = 2x - 1
