B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
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
Step-by-step explanation:
Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
...
Simple Interest Example:
Simple Interest
1 Year S.I = (1000 ×5 × 1)/100 = 50
2 Year S.I = (1000 × 5 × 2)/100 = 100
3 Year S.I = (1000 ×5 × 3)/100 = 150

Step-by-step explanation:
this is because standard form of numbers are supposed to be 1 and 9
15/hr
15x5 = 75 dollars. you can build the ratio table using the rate of change.
