Y ^-7 / y ^-13 20 POINTS PLEASE HELP

Answers

Answer 1

Answer:

Answer:

The answer is

${y}^(6)$

Step-by-step explanation:

$\frac{ {y}^( - 7) }{ {y}^( - 13) }$

To solve the expression we use the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

$\frac{ {a}^(x) }{ {a}^(y) } = {a}^(x - y)$

So we have

$\frac{ {y}^( - 7) }{ {y}^( - 13) } = {y}^( - 7 - - 13) = {y}^( - 7 + 13)$

We have the final answer as

${y}^(6)$

Hope this helps you

The difference between 4,632 and 20,000 is what number

Answers

When finding the difference between you will need to subtract. So lets subtract
4632-20000
And you get -15368.
So the differences between 4,632 and 20,000 is -15368

Difference means to minus which will get our difference.

4632 - 20000 = -15368

SO 4632 - 20000 is equal to negative(-)15368 (-15368)

Describe how a statistical question yields an answer with variability. Give a example.

Answers

Statistics is not an exact science, meaning that with any answer, there will be variance. This is because the sample size used to obtain values is always smaller than the population being studied.

Explanation:

A question with variability is a question that does NOT have one definitive answer. Instead, it has a range of different answers.

A statistical question is one that can be answered by collecting data. By nature, there will be variability in that data, because no two people will necessarily respond the same way.

An example of a statistical question would be asking a classroom of students how many hours they studied that week. After collecting the data, there will be multiple answers instead of just one.
