Answer:
the probability of having sickle cell anemia given that you are African-American is P( B|A) =0.288
Step-by-step explanation:
Using Bayes's theorem
P( B|A) = P( A∩B)/P(A)
where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A
if B= probability of having sickle cell anemia and A= probability of being African-American
then
P( A∩B) = 0.13
P(A) = 0.45
then
P( B|A) = P( A∩B)/P(A) = 0.13/0.45 = 0.288
P( B|A) =0.288
Answer: 1/4x + 1/2x = 12
x = 16
Step-by-step explanation: combine the 1/4x and 1/2x to 3/4x because they are like terms then divide 12 by 3/4 or 0.75 to get 16
X will equals -5 because 2-(-5)=3
Answer:
55 ft
Step-by-step explanation:
Perimeter is the distance round a given shape. For an hexagon, since it has six equal sides, xomsidering that it is regular, its perimeter is given by
P=6a
Where P is the perimeter and a is the length of its sides.
Considering that a is given as 9ft 2 in then
P=6(9ft 2 in)=54 ft 12 in
Since 1 ft is equivalent to 12 inches then the perimeter is 54+1=55 ft
