Answer:

Step-by-step explanation:

The median is the middle value of the data in ascending order. If there is no exact middle then it is the average of the two values either side of the middle.

Arrange in ascending order

12, 15, 15, 18, 20, 29, 33, 42

The middle is between 18 and 20

median = $\frac{18+20}{2}$ = $\frac{38}{2}$ = 19

Answer:

Step-by-step explanation:

Hey diddle diddle the medians in the middle you add then divide for the mean. the mode is the one that appears the most and the range is the difference in between.

Median: you have to organize the numbers from least to greatest then eliminate one by one.

12, 15, 15, 18, 20, 29, 33, 42

eliminate 12, and 42

15, 15, 18, 20, 29, 33

eliminate 15, and 33 ... so on

once you get to the median you end up with two numbers.

18, 20

because you can only have one median you find the number between, which in this case would be 19

The Ramos family wants to buy a Play Station 4 for $299.00, along with accessories and games. A wireless controller costs $44.99

Lilit [14]

Answer:

Part A: 299 + 45A + 30B + 50c

Part B: 569 (or 570 if you round it up)

Step-by-step explanation:

Part A:

Because there is no variable for the number of PlayStation 4s, let's assume that there is only one. That will be 299.

If A is the number of wireless controllers and each wireless controller is worth 45 dollars each, the price for the wireless controller(s) is 45A.

If B is the number of wireless controller charging stations and each wireless controller charging station cost 30 dollars, then the price of the wireless controller charging station(s) is 30B

If C is the number of games and each game cost 50 dollars, then the price of the game(s) is 50C

Put that all together, and we get 299 + 45A + 30B + 50c.

Part B:

Let's plug the numbers into the formula.

A = 2

B = 1

C = 3

$299 + 45A + 30B + 50c = 299 + 90 + 30 + 150 = 569\ dollars$

I need help I don't understand this

Naddik [55]

Answer:

x = 2

Step-by-step explanation:

-3 +6x = 25 -8x

Add 8x to each side

-3 +6x+8x = 25 -8x=8x

-3+14x = 25

Add 3 to each side

-3+3+14x = 25+3

14x = 28

Divide by 14

14x/14 = 28/14

x = 2

Xelga [282]

$\frac{16}{200} = \frac{2}{25}$
is the proportion of tires that are defective so
$\frac{2}{25} \times 20000 = 1600$
so we would expect around 1600 tires to be defective
