Brent count to 10 red cards 10 Blackhearts and 20 blue cards in a deck of cards what is the radio of red cards to other cardsj

1/4

Step-by-step explanation:

10+10+20=40

10 of those are red cards which makes it 10/40 which is simplified to 1/4.

10:30 (simplified- 1:3)

Step-by-step explanation:

there are 10 red cards so the first number would be 10

the other cards are black hearts and blue cards, if you add them together that is 30 cards, therefore, the answer is 10:30

There are two ways to find the median, depending on what situation it is.

The first, is to simply arrange the number set into proper numerical format (least to greatest), then count from both sides towards the middle to find the median or middle number.

The latter, is when we have a number set that has an equal amount of numbers. For this, we would again, arrange it into proper numerical format, and the count from both sides up. However, there will be two numbers at the middle. So, what we do, is that we have to add them up and then divide by 2 since there are only those two numbers at the middle. Once, the numbers are added up and divided by 2, you will get the resulting median.

Example: Find the median of the data set below.

1,2,3,4,5,6,7,8,9,9

There are 10 numbers in this data set.

It's already been arranged into proper numerical format.

So, all we have to do is, find the two middle numbers and then add them up and divide.

The two numbers at the middle are: 5 and 6.

Add them up.

5 + 6 = 11

Divide by 2.

11/2 = 5.5

Thus, the median of the data set is 5.5
