Explain how the percent equation relates proportional quantities

the percent equation being
PART = PERCENT * WHOLE

Answers

Answer: This is the best I could find for you

Step-by-step explanation:

"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."

7y+5z-2y+z

grade 7 math

Answers

Answer:

Step-by-step explanation:

7y+5z-2y+z

Group the two y and the two z together

7y-2y = 5y

5z+z= 6z

(a variable with out a number is = to 1)

so it would be  5y+6z

Hope this helps

The answer would be 5y+6z.
The reason for this is because only like terms can be added and subtracted.

Step-by-step explanation:

How do you find the probability of two events A and B when A and B are independent? dependent?

A.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

B.For independent events, find the probability of the first event, find the probability of the second event, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply.

C.For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add. For dependent events, find the probability of the first event, find the probability of the second event, and then add.

D.For independent events, find the probability of the first event, find the probability of the second event, and then add. For dependent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then add.

Answers

Answer:

I think it is A, but i am not sure, sorry

Step-by-step explanation:

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

A. For independent events, find the probability of the first event, find the probability of the second event after the first event occurs, and then multiply. For dependent events, find the probability of the first event, find the probability of the second event, and then multiply.

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.
