If you would like to write <span>(-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:

</span>(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (<span>√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i
</span>
The correct result would be -18 * i.

Answer:

See explanation below.

Step-by-step explanation:

The definition of Type I error is the rejection of a true null hypothesis, the type I error is also known as "False positive". Remember that a null hypothesis states that two variables are not related and that there is no association between these hypothesis. Therefore, if the Type I error rejects a true null hypothesis it means that because of this error, the findings indicate that there is actually a relation between two variables when there really isn't one.

In the case of this problem, the researcher made the claim that most middle school students that are bullied have low self-esteem. This means that<u> the researcher concluded that there's a relation between being bullied and having a low self-esteem. </u>

If Anton is concerned that the researcher made a type I error, it means that Anton thinks that the study gave some "false positives", leading the researcher to believe there's a correlation between bullying and low self-esteem when there really isn't a correlation between them.

Answer:

  120

Step-by-step explanation:

The function C(n, k) can be written in terms of factorials:

  C(n, k) = n!/(k!(n -k)!)

Then ...

  C(16, 2) = 16!//(2!(16 -2)!) = (16·15)/(2·1)

  C(16, 2) = 120
