Of people who died in the United States in a recent year, 86% were white, 12% were black, and 2% were Asian. (We will ignore the
Marianna [84]

Answer:

To three decimal place  = 0.030

Step-by-step explanation:

Let probability of death in white p (WH) = 86%

Let probability of death in black p(B) =12%

Let probability of death in Asian p(A) = 2%

Probability of death caused by diabetes among white will be 2.8% of p (WH) = 0.86 x 0.028 = 0.02408

Probability of death caused by diabetes among black will be 4.4% of p (B) = 0.12 x 0.044 = 0.00528

Probability of death caused by diabetes among Asian will be 3.5% of p (A) = 0.02x 0.035 = 0.0007‬

If a sample is chosen and the cause is diabetes then the probability will be

Probability of death caused by diabetes among white or Probability of death caused by diabetes among black or Probability of death caused by diabetes among Asian  

0.02408 +0.00528 +0.0007 = 0.03006

To three decimal place  = 0.030

PLEASE HELP ASAP ): 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
eimsori [14]

Answer:

  c.  25

Step-by-step explanation:

(f ∘ g)(-2) = f(g(-2)) = f(-2-3) = (-5)² = 25

For this problem, it seems to work best to evaluate g(-2), then evaluate function f on that. (In other cases, it might be useful to simplify the composite function first.)

balu736 [363]

Answer:

2 years 5 months

Step-by-step explanation:

TO solve, convert everything to months

1 year has 12 months, so 5 years would have 60, because we multiply by 5.

Then we add the remaining 2 months, 60+2 =62

Then we can convert 2 years to 24 months. Then we add the remaining 9 months to get 24+9, 33

Then we subtract the 2, and get 62-33= 29, and we divide by 12 to convert to years and months. 29 divided by 12 is 2 and 5 months

so your answer is 2 years and 5 months
