Answer:
Step-by-step explanation:
Area of square = side * side
= 4 * 4
= 16 sq.ft
Area of triangle =
Area of the figure = area of square + area of triangle
= 16 + 4
= 20 sq.ft
Answer:
So 13 x 3= 39
Step-by-step explanation=
your just gonna multiply 13x3 to get your answer
Hope this helped :D
Answer
a) 0.035
b) 0.14
Step-by-step explanation:
Let J be the event that Joe has the disease.
Let The be the event that Joe's test is positive.
Pr(J) = 1/2%
= 0.5/100 = 0.005
Pr(J') = 99.5%
= 0.995
Pr(T|J) = 98%
= 0.98 since 2% if the time if a person having the disease is omitted ("false negative ")
Pr(T|J') = 3% = 0.03 since there are 3 false positives
a( Pr(T) = us the probability that Joe tests positive
Pr(T) = Pr(T|J)* P(J) + Pr(T|J')*Pr(J')
= (0.98*0.005) + (0.03*0.995)
= 0.00049 + 0.02985
= 0.03475
= 0.035
b) Pr( J|T) = Pr(JnT) / Pr(T)
= (Pr(T|J)*Pr(J)) / Pr(T)
= (0.005*0.98) / 0.035
= 0.0049/0.035
= 0.14
