One real-world application of ratios that affects many people involves measuring cholesterol in blood. The ratio of total cholesterol to HDL cholesterol is one way doctors assess a person's overall health. A ratio of less than
to
is considered good.
Hector's total cholesterol is
mg/dl and his HDL cholesterol is
mg/dl.
ⓐ Find the ratio of his total cholesterol to his HDL cholesterol.
ⓑ Assuming that a ratio less than
to
is considered good, what would you suggest to Hector?
Solution
ⓐ First, write the words that express the ratio. We want to know the ratio of Hector's total cholesterol to his HDL cholesterol.
Write as a fraction.
Substitute the values.
Simplify.
ⓑ Is Hector's cholesterol ratio ok? If we divide
by
we obtain approximately
so
Hector's cholesterol ratio is high! Hector should either lower his total cholesterol or raise his HDL cholesterol.
To find the ratio of two measurements, we must make sure the quantities have been measured with the same unit. If the measurements are not in the same units, we must first convert them to the same units.
We know that to simplify a fraction, we divide out common factors. Similarly in a ratio of measurements, we divide out the common unit.
The Americans with Disabilities Act (ADA) Guidelines for wheel chair ramps require a maximum vertical rise of
inch for every
foot of horizontal run. What is the ratio of the rise to the run?
Solution
In a ratio, the measurements must be in the same units. We can change feet to inches, or inches to feet. It is usually easier to convert to the smaller unit, since this avoids introducing more fractions into the problem.
Write the words that express the ratio.
Ratio of the rise to the run
Write the ratio as a fraction.
Substitute in the given values.
Convert 1 foot to inches.
Simplify, dividing out common factors and units.
So the ratio of rise to run is
to
This means that the ramp should rise
inch for every
inches of horizontal run to comply with the guidelines.
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
