Jane completes several example problems that ask her to the find the opposite of the opposite of a number, and for each example, the result is a positive number. jane concludes that when she takes the opposite of the opposite of any number, the result will always be positive. is jane correct? why or why not?

Jane is not correct.

Step-by-step explanation:

Jane must have complete several examples using positive numbers. That conclusion does not apply for negative numbers.

Let's see an example:

Given the number 5:

Note that is the same number and it is positive.

However, if we check the same situation with a negative number:

Given the number -3:

In conclusion, Jane's conclusion is wrong. The opposite of the opposite number is not always a positive number.

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
