where n represents number of sides.

In a quadrilateral there are four sides,

So, plugging 4 in the formula :

What is the difference between mean and median

Answers

The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.

But the median is the number in the middle Number.

What if you have 2 medians, though?

Well, that’s easy to solve IMO.

F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25

The median is either 23 or 24, right?

Okay. That’s simple. But what exactly do we do?

Let me show you:

So get the sum of 23 and 24, which is 47.

Now divide 47 by 2. And what do we get?

23.5.

Now round that, and you get 24. So 24 is the median!

Hope that helps!

Answer:

mean is the AVERAGE of all numbers

Step-by-step explanation:

because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!

and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

hope this helps

Answers

i think it’s c if i’m not wrong

Probability is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability of Nancy picking a purple marble is 1/12

Option A is the correct answer.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

There are three different colors- blue, red, and purple.

The probability of choosing a blue marble is 0.25

The probability of picking a red marble is 2/3

The total probability of always 1.

The probability of Nancy picking a purple marble.

= 1 - (0.25 + 2/3)

= 1 - (1/4 + 2/3)

= 1 - (3 + 8)/12

= 1 - 11/12

= 1/12

Thus,

The probability of Nancy picking a purple marble is 1/12

Option A is the correct answer.
