Error Analysis! Answer Both Parts Of The Question.Kaitlyn Solved The Equation 5y = 15 And Found The Answer

Answers

Answer 1

Answer:

Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side

so you would do 5/5 - cancels out

15/5=3

y=3

Step-by-step explanation:

have a great day :D

Answer 2

Answer:

y = 3

Explanation (Part A):

She was supposed to divide five both sides. However, she divided one side by five and multiplied five on the other side, which makes her answer incorrect. She got confused that if any side is divided by a number, the other side must be divided by that same number.

Solution (Part B):

5y = 15=> 5y/5 = 15/5=> y = 3

The correct answer must be 'y = 3'.

What is the probability that an international flight leaving the US is delayed in departing given that the flight is a transpacific flight?  

Answer:

[tex]P(D|P) = 0.50[/tex]

Step-by-step explanation:

Given

[tex]P(D) = 0.26[/tex]

[tex]P(P) = 0.50[/tex]

[tex]P(D\ and\ P) = 0.13[/tex]

The question illustrates conditional probability and it is represented as:

P(D|P)

This is then calculated as:

[tex]P(D|P) = \frac{P(D\ and\ P)}{P(D)}[/tex]

So, we have:

[tex]P(D|P) = \frac{0.13}{0.26}[/tex]

[tex]P(D|P) = 0.50[/tex]

Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum

Answers

Answer:

Step-by-step explanation:

x+y = 175

y = 175 - x

f(x) = (x+3)(y+4)

= x(175-x) + 3(175-x) + 4x + 12

= 175x - x² + 525 - 3x + 4x + 12

= -x² +176x + 537

f'(x) = -2x + 176

maximum when x = 88

y = 175-x = 87

Answer:

  y = 3x -6

Step-by-step explanation:

The three turning points of the terms divide the graph into 4 pieces. We can consider what functions apply in each piece.

x < -2

All terms are negated:

  y = (3 -x) -(x +2) -(5 -x) = -x -4

-2 < x < 3

The first and last terms are negated:

  y = (3 -x) +(x +2) +(x -5) = x

3 < x < 5

The last term is negated:

  y = (x -3) +(x +2) +(x -5) = 3x -6

5 < x

No terms are negated:

  y = (x -3) + (x +2) -(x -5) = x +4

_____

In the region of interest, the equation simplifies to y = 3x -6.

The ratio of the lengths of its sides is:

short leg   :   long leg  :   hypotenuse

The short leg measures half the hypotenuse.

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? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which words from the text describe what our brains use to fill in gaps in memory?
