Answer:
i think its y = 2.5x ?
Step-by-step explanation:
for every 5 units of black paint, there are 2 units of white paint,, this can be represented as
2y = 5x
divide everything by 2 to isolate y and you get
y = 2.5x
5+3z=___
5+3(7)=26
How? Multiply 3x7=21
add 21 and 5 which will equal 26
answer: 26
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:
Because it is a mixed fraction and it should be renamed in order to solve your problem, for the other one CAN NOT be converted into a mixed fraction.
