Travka [436]

Answer:

Report the length as x inches to the nearest quarter of an inch.

See the example below

Step-by-step explanation:

Report the length as x inches to the nearest quarter of an inch.

E.g : If the actual length is 2.4 inches then the reported length would be 2.5 in

Similarly if the actual length is 2.3 inches then the reported length would be 2.25 in

\\ \rm\rightarrowtail 5x^2-5x-4x+4=0

\\ \rm\rightarrowtail 5x(x-1)-4(x-1)=0

\\ \rm\rightarrowtail (5x-4)(x-1)=0

\\ \rm\rightarrowtail x=4/5,1

A certain virus infects one in every 200 people. a test used to detect the virus in a person is positive 70​% of the time when t
V125BC [204]

We're told that

P(A)=\dfrac1{200}=0.005\implies P(A^C)=0.995

P(B\mid A)=0.7

P(B\mid A^C)=0.05

a. We want to find P(A\mid B). By definition of conditional probability,

P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}

By the law of total probability,

P(B)=P(B\cap A)+P(B\cap A^C)=P(B\mid A)P(A)+P(B\mid A^C)P(A^C)

Then

P(A\mid B)=\dfrac{P(B\mid A)P(A)}{P(B\mid A)P(A)+P(B\mid A^C)P(A^C)}\approx0.0657

(the first equality is Bayes' theorem)

b. We want to find P(A^C\mid B^C).

P(A^C\mid B^C)=\dfrac{P(A^C\cap B^C)}{P(B^C)}=\dfrac{P(B^C\mid A^C)P(A^C)}{1-P(B)}\approx0.9984

since P(B^C\mid A^C)=1-P(B\mid A^C).
