The numerical expressions represent the final depth of the diver will be the negative 200 + 12 1/3 (4.5). Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A diver begins at sea level and dives down 200 feet.
He ascends at a steady rate of 12 1/3 for 4.5 minutes.
Then the numerical expressions represents the final depth of the diver will be
Let the negative sign for the downward and the positive sign for upward.
Then we have
⇒ - 200 + 12 1/3 (4.5)
Then the correct option is C.

Answer:
It is an Observational study. The population of interest is fifth-grade boys and girls in your school district.
Step-by-step explanation:
Consider the provided information.
Observational study is the study in which observer only observe the subjects, and measure variables of interest without allocating treatments to subjects.
Experiment study is the study in which the researchers are applying treatments to experimental units in the research, then the effect of the treatments on the experimental units is observed.
Now consider the provided survey.
Here, students are randomly selected form the population of fifth-grade boys and girls.
The aim of the study is to observe the subjects and no treatment was administered to the students.
Thus. it is an Observational study.
The population of interest is fifth-grade boys and girls in your school district.
The study is to observe who is faster fifth-grade boys or fifth-grade girls at solving Ken-Ken puzzles.
Answer:
A.
Step-by-step explanation:
π/4 radians = 45°
In a 45-45-90 degree angle, the ratio of the lengths of the sides is
1 : 1 : √2
x = y = 1/√2
x = y = √2/2
Answer: A.
