Z = (x -μ)/σ
.. = (99 -88)/5
.. = 11/5
.. = 2.2
The z score is 2.2.
Answer
x = 59.5
Explanation
Based on the given conditions, formulate:
Rearrange unknown terms to the left side of the equation:
Calculate the sum or difference:
Divide both sides of the equation by the coefficient of variable:
Calculate the product or quotient x = :59.5
Answer x = 59.5
A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.

Objectivist Epistemology is a college of thinking that states the real world is independent of the individual conscious mind.
<h3>What is Objectivist Epistemology?</h3>
Objectivist Epistemology is a branch of epistemology aimed at understanding the real validity of natural phenomena beyond the human conscious mind.
Objectivist Epistemology and critical thinking are analyzed by Ayn Rand in the authored book 'Introduction to Objectivist Epistemology'.
In conclusion, Objectivist Epistemology is a college of thinking that states the real world is independent of the individual conscious mind.

According to the research, Dr. Smithe should use naturalistic observation to investigate aggressive preschoolers.
<h3>What are naturalistic observations?</h3>
It is a method used in research and whose basis is to observe the subjects in the place where they live, without the researcher being disturbed in the least.
This allows detailing the behavior of the subjects that we record is what, in fact, the behavior that should happen in their habitat, under those conditions, obtaining real results, without any type of alteration.
Therefore, we can conclude that according to the research, Dr. Smithe should use naturalistic observation to investigate aggressive preschoolers.
