Hi, Laura! ;)
<h2>The answer to the first question is 5,62.</h2><h2><em>Here is the step by step solution</em>: </h2>They want to know the center of a distribution. Another word for center is middle. When you have a set of numbers, you can find the middle by calculating the mean, the "average" of the data set.
1) Add all the numbers: 12,8 + 5,7 + 7,9 + 1,3 + 3,2 + 2,8 = 33,7
2) Divide the sum by the quantity of numbers, which is 6: 33,7 / 6 = 5,616
The closest number to 5,616 is 5,62.
==========================================================
Now let's answer your second question.
<h2>The correct answer is, indeed, 0,14.</h2><h2><em>How do we get to this number? Here is the step by step solution:</em></h2>1) First step is to find out how many possible outcomes you have. It is the
number of raffle tickets in the box: 200.
2) Then, let's define the number of tickets that are prizes: 4 + 8 + 16 = 28.
The probability of selecting a prize ticket is the number of prize tickets divided by all the raffle tickets in the box: 28 / 200 = 0,14.
Now, let's practice Probability with another Brainly problem:
Good luck, Laura! :)

We need to find mean of given integers.
We have -16,39,-10,-16,12,31.
In order to find mean, we need to add all the given inetgers.
Therefore, putting plus sign in between integers.
-16+ 39+ (-10)+(-16)+12+31 .
We will add all positive number 39+12+31 = 82
We will add all negative numbers by negative numbers, -16-10-16 = -42.
Therefore, -16+ 39+ (-10)+(-16)+12+31 = 82 - 42 = 40.
We have given total 6 integers.
So, in order to find the mean, we need to apply following formula
Mean =
We get,
Mean = 40/6 = 6.66666......
We can round it to 6.67.
Therefore, mean of the given integers = 6.67 (approximately) .
