The diver's depth is indicated by a value of -5.875 feet before he or she swims to the surface. This is further explained below.
<h3>What is a diver?</h3>
Generally, A person who can breathe underwater for extended periods of time without returning to the surface, any of several species of birds that feed mostly by diving into bodies of water.
In conclusion, It has been shown that a diver must swim upwards of 5.875 feet in order to reach the water's surface. The diver is rising because they are approaching the surface of the water. Since the diver began his journey below the water's surface, his elevation was negative until he reached the surface.
For this reason, a number of -5.875 feet is used to represent the diver's depth just before surfacing.

There is a 0.9968 probability that a randomly selected 50-year-old female lives through the year (based on data from the U.S. Department of Health and Human Services).
-------------------
A Fidelity life insurance company charges $226 for insuring that the female will live through the year. If she does not survive the year, the policy pays out $50,000 as a death benefit.
From the perspective of the 50-year-old female, what are the values corresponding to the two events of surviving the year and not surviving?
----
Ans: -226 ; 50,000-226 = 49774
-------------------------
If a 50-year-old female purchases the policy, what is her expected value?
WORK TRIED:
In the event she lives, the value is -$226. In the event she dies, the value is $49,774.
----
E(x) = 0.9968*(-226) + 0.0032(49774) = -$66

We can make everything have the same denominator so we can add, subtract, and compare them:
The common denominator between 2, 4, and 8, is 8.
7/8 = 7/8
1/2 = 4/8
1/4 = 2/8
The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:
Laura : 7/8
Daniel: 4/8
Annabelle: 2/8
4/8 + 2/8 = 6/8
So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:
7/8 > 6/8.
This means that Laura rowed more than Daniel and Annabelle.
