Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,029 feet. The lowest feature on Earth is the Challenger Deep with an elevation -35,797 feet. What elevation does sea level represent in this scenario? Which feature is farther from sea level?

The farthest point is the Challenger Deep

Step-by-step explanation:

Given

Solving (a): The sea level

Both elevations had signs in front of them.

The sea level is the point at the neutral level, neither positive nor negative.

Hence:

Solving (b): Farthest Point.

The farthest point is the one with the highest magnitude.

Comparing

 to  

-35,797 ft has the highest magnitude.

Hence:

The farthest point is the Challenger Deep

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
