dlinn [17]

Answer:

0.15N

Step-by-step explanation:

Given data

Mass= 0.0056kg

distance=  4.85m

Velocity= 11.4m/s

The expression for the force is

F= mv^2/r

substitute

F=  0.0056* 11.4^2/4.85

F=  0.0056*129.96/4.85

F= 0.727776/4.85

F= 0.15N

Hence the force is 0.15N

Grumpy Corp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines
Vedmedyk [2.9K]

Answer:

Hence, the probability of a Negative test is P(T^C)=0.5904.

Step-by-step explanation:

(a)

Let D= Drug user and T= Test positive

Probability of drug users P(D)=36\%=0.36

                                    P(\frac{T}{D})=96\%=0.96

                                   P(\frac{T^c}{D^c})=90\%=0.90

(b)

Find the Probability of a Negative test,

     P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)

\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36

\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36

\Rightarrow P(T^C)=0.576+0.0144

\Rightarrow P(T^C)=0.5904
