The life span of a battery is the amount of time the battery will last. The distribution of life span for a certain type of battery is approximately normal with mean 2. 5 hours and standard deviation 0. 25 hour. Suppose one battery will be selected at random. Which of the following is closest to the probability that the selected battery will have a life span of at most 2. 1 hours?.

Answers

Answer 1

The probability that the selected battery will have a life span of at most 2.1 hours is 5.48%.

z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x\ is\ raw\ score, \mu\ is\ mean,\sigma\ is\ standard \ deviation[/tex]

Given that μ = 2.5, σ = 0.25.

For x < 2.1:

[tex]z=\frac{2.1-2.5}{0.25}=-1.6[/tex]

From the normal distribution table, P(x ≤ 2.1) = P(z < -1.6) = 0.0548 = 5.48%

The probability that the selected battery will have a life span of at most 2.1 hours is 5.48%.

Which statement best explains a difference between a character vs. Self conflict and a character vs. Character conflict?.

Answers

Answer: A character vs. Self conflict and a character vs. Character conflict are two different types of conflicts commonly found in literature. Here's an explanation of the difference between the two:

Character vs. Self Conflict:

Character vs. Self conflict, also known as internal conflict, occurs when a character struggles with their own thoughts, emotions, beliefs, or decisions. It is a psychological or emotional struggle within the character's mind. The conflict arises from a moral dilemma, self-doubt, guilt, fear, or any internal obstacle that the character must overcome.

Example: A protagonist who is torn between following their principles and doing what is morally right, even if it puts them in danger or conflicts with their personal desires, is experiencing a character vs. Self conflict.

Character vs. Character Conflict:

Character vs. Character conflict, also known as external conflict, involves a struggle between a character and an external force, typically another character. This type of conflict arises from opposing goals, interests, or ideologies between two or more characters. The conflict is usually more overt and may involve verbal or physical confrontations.

Example: In a story, the hero and the villain engage in a battle of wits and physical confrontation. This conflict is an example of character vs. Character conflict.

In summary, the key difference lies in the source of the conflict. Character vs. Self conflict is internal, involving the character's own thoughts and emotions, while character vs. Character conflict is external, involving clashes between different characters and their opposing objectives or viewpoints. Both types of conflict play essential roles in developing the plot and character arcs in a story.

From the complete information, the standard cost for the backpack is calculated thus:

Materials = $9540

Direct labor = $5936

Variable manufacturing overhead= $1484

Total standard cost = $16960

Since the number of backpacks is 530, the standard cost for a single backpack will be:
