Antigone tells her sister, "’tis thine to show / if thou art worthy of thy blood or base." the word or tells you that base is being contrasted with worthy of thy blood. given that, what do you suppose base means? write your ideas here.

Answers

The word "base" as used in the passage refers to; loyalty to the family, to the family bond that Ismenia has.

What is the meaning of the word in the passage?

Antigone speaks the words in the given passage to her sister Ismenia. Now, in these words, Antigone questions Ismenia's loyalty and commitment to the family by the use of the word "base" to mean family loyalty.

The reason for use of that word is because their brother was banned from receiving a decent funeral, which prevented his soul from being able to rest in peace. The king then ordered that whoever made a feneral for the brother of Ismenia and Antigona would be condemned to death. However Antígona, in loyalty to her brother, was willing to take that risk and wanted to know if Ismenia had the same loyalty.

Suppose that we have this spinner. what is the probability of landing on 4 after landing on 4?

Answers

The probability that the spinner lands on 4 is its likelihood

The probability of landing on 4 after landing on 4 is 1/n^m

How to determine the probability?

Assume that the numbers on the spinner are not repeated, the probability that a spinner lands on 4 is:

P(4) = 1/n

Where n represents the number of sections on the spinner

The probability that the spinner lands on 4 again is the same for the number of times the spinner is spun

Hence, the probability of landing on 4 after landing on 4 is 1/n^m where m represents the number of spins

Target profit is $100,000; total fixed costs are $120,000, and total variable costs are $500,000, the markup percentage is

Answers

The markup percentage to the variable cost using the variable cost method is 40%.

What is markup percentage?

The markup percentage to the variable cost using the variable cost method can be obtained by dividing the addition of the target profit and total fixed cost by the total variable cost as follows.

We know that:

Total fixed cost

= Fixed overhead costs + Fixed selling and administrative costs

= $120,000 + $50,00

= $170,000

The markup percentage to the variable cost

= (Target profit + Total fixed cost) / Total variable cost

= ($100,000 + $170,000) / $675,000

= $270,000 / $675,000

= 0.40, or 40%.

Answers

The length of the end of the banjo string when the fundamental frequency is 330Hz will be 0.61m.

How to calculate the length?

The fundamental frequency will be given as:

f = v/2L

Let the required length be represented as L2.

Therefore, f1/f2 = L1/L2

L2 = (294 × 0.69)/330

L2 = 0.61m

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven?
