Ahelicopter is hovering 100 meters above the ocean. directly below it, a submarine is at a depth of 200 meters. the altimeter on the helicopter reads meters, which means it is 100 meters sea level. the altimeter on the submarine meters, which means it is 200 meters sea level

1. 100

2. Above,

3. ,

4. Below.

Step-by-step explanation:

We have been given that a helicopter is hovering 100 meters above the ocean. Directly below it, a submarine is at a depth of 200 meters. We are supposed to fill in the given blanks.

We know the helicopter is 100 meters above the sea level, so its altitude will be positive 100.

The altimeter on the helicopter reads 100 meters, which means it is 100 meters above sea level.

We know the submarine is at depth of 200 meters, which means that it is 200 meters below the sea level, so its altitude will be negative 200.

The altimeter on the submarine reads meters,which means it is 200 meters below sea level.

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

ratio is 2 : 9

the answer is three

13.5 : 3
