Hey! All you have to do is divide mass by volume.
42.5/5.4=7.87
28.8/2.55=11.29
69.5/3.6=19.3
46.4/6.5=7.14
61/5.4

Answer:

2 miles 2 yards

Step-by-step explanation:

There are 1760 yards in a mile, so you are effectively performing the division ...

(9185 380/1760) ÷ 4590

where the number in parentheses is a mixed number of miles.

You do this division the same way you do any mixed-number division. There are different possible methods you can use. One of them is to convert the mixed number to an improper fraction, then divide.

9185 380/1760 = 9185 19/88 = (88·9185 +19)/88 = 808299/88

Then this is divided in the usual way:

$\dfrac{808299}{88}\div4590=\dfrac{808299}{88\cdot4590}=\dfrac{808299}{403920}=2\dfrac{459}{403920}=2\dfrac{1}{880}$

Finding the quotient and remainder is straightforward. Reducing the fraction involves finding common factors in the numerator and denominator. As it turns out, 459 is a factor of 403920, so the fraction reduces as shown.

Now, we need to convert 1/880 miles back to yards.

((1/880) mi) × (1760 yd/mi) = 2 yd

So, the quotient you seek is ...

2 miles 2 yards

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
