In the late 18th century, a decimal clock was proposed, in which there were 100 'minutes' in one 'hour' and 10 'hours' in one da
Marrrta [24]

Answer:

2:50

Step-by-step explanation:

On an ordinary clock, there are 24 hours.

1)  6/24 = 0.25   (The percentage in which the day has passed)

2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50

3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50

Assume that the probability of having sickle cell anemia is 0.15 and the probability of being African-American is 0.45 in a give
irina1246 [14]

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
