Mean is another word for  average; average number of a data set.

Problems with steps:

---------------------------------------------------------------------------------------

1) 9, 3, 6

Average =  Sum/Count

Sum =   18/6

Count = 3

2) 14, 12, 17, 9

52/4

Mean = 13

3) 15,8,10,5,7

= 45/5

Mean = 9

4) 18,19,11

= 48/3

Mean = 16

5) 4,20,16,4

= 44/4

Mean = 11

6) 12,11,12,20,15

= 70/5

Mean= 14

7) 19,8,3

= 30/3

Mean = 10

Mean = 7

9) 12,15,17,2,14

60/5

Mean = 12

= 36/3

Mean = 12

11) 5,2 ,0,1

= 8/4

Answer:

4.5 inches

Step-by-step explanation:

We are given the formula:

V = \pi r^{2}h

Plug in the the radius (3) and volume (127.23):

127.23 = 3.14(3)^{2} h

Square the 3 :

127.23 = 3.14(9)h

Multiply the pi & volume:

127.23 = 28.26h

Divide both sides by 28.26:

127.23 ÷ 28.26 = 28.26h ÷ 28.26

h = 4.5021231...

I hope this helps!

Can somebody help me with this? I'm bad at this stuff <.
Sladkaya [172]

Answer:

Prime numbers are whole numbers that has factors of 1 and itself.

Example: 2 is a prime because there is no way you could factor it except 1 and 2.

Composite numbers have more factors which also include 1 and itself.

Example: 50 is composite because it has factors more than 1 and itself.

5 is a factor of 50; 10 is a factor of 50.

So let's begin sorting.

<em>Prime: 7, 11, 31.</em>

Composite: 4, 8, 10, 27.

Hope this helps! :)

A store marks up the price of a sweater by $7.35. The total cost of the sweater is 25.65. How much does the store pay for the sw
UNO [17]

Answer: the store paid $18.3 for the sweater

Step-by-step explanation:

Let x represent the amount that the store paid for the sweater.

A store marks up the price of a sweater by $7.35. This means that the new or current price of the sweater at the store would be

7.35 + x

The total cost of the sweater is 25.65. Therefore, an equation to represent the problem would be

7.35 + x = 25.65

Subtracting 7.35 from the left hand side and the right hand side of the equation, it becomes

7.35 + x - 7.35 = 25.65 - 7.35

x = $18.3
