Answer:

Step-by-step explanation:

The median is the middle value of a set of data, and the mode is the value that appears most often.

For example:

1. The values given are: 6, 9, 2, 4, 3, 6, 5

To find the median, we have to list the numbers in order from smallest to largest.

2, 3, 4, 5, 6, 6, 9

Then, cross out a number on the left and on the right. Repeat this process until only one or two numbers are not crossed out.

In this case, all of the numbers except for 5 are crossed out.

This means that 5 is the median.

To find the mode, all we have to do is see which number appears the most. In this set of number, the number 6 appears twice, more than any other number.

So, the mode is 6.

You can do the same thing for the other problems.

To find the mean of a set of values, you have to add all of the numbers together and divide them by the total amount of numbers in the set.

For example:

7. There are 8 numbers in this set. These numbers are:

21, 23, 27, 28, 32, 32, 34, 43

First, we have to add all of the numbers together.

21 + 23 + 27 + 28 + 32 + 32 + 34 +43 = 240

Now, we have to divide 240 by 8(the total amount of numbers in the set)

240/8 = 30

The mean is 30.

Answer:

Step-by-step explanation:

A and B are both equal (corresponding parts)

A = B

5x - 5 = 3x + 13               Add 5 to both sides

5x = 3x + 13 + 5              Combine

5x = 3x + 18                    Subtract 3x from both sides

5x - 3x = 18                     Combine

2x = 18                            Divide by 2

2x/2 = 18/2

x = 9            

Angle B

B = 3x + 13                      Let x = 9

B = 3*9 + 13

B = 27 + 13

Angle B = 40

Answer:

First on is 0.75

Second is 22/52 (not sure about this one though)

Step-by-step explanation:

For the first one:

P(aUb) = p(a) + p(b) - p(a^b)

0.6 = 0.4 + 0.5 - p(a^b)

p(a^b) = 0.3

P(a/b)= p(a^b)/p(a)

P(a/b)= 0.3/0.4

P(a/b)= 0.75

For the second one:

Total of the cards are 52

Diamonds are 13 out of that 52

Face cards are 12 out of that 52

Diamond OR face cards means p(aUb)

And that equals p(a)+p(b)-p(a^b)

p(a^b) means the intersection between the two, there are three common cards between diamonds and face cards, so p(a^b)=3

13/52 + 12/52 - 3/52= 22/52
