Which statement describes the symmetry of the data in the two box plots?

inysia [295]

Answer:

The data in country B are more symmetric than the data in country A.

Step-by-step explanation:

The following information is missing:

<em>The box plots show the average wind speeds, in miles per hour, for various cities in two different countries. Average Wind Speeds of Cities in Country A 2 box plots. The number line goes from 1 to 11. For the average wind speeds of cities in country A, the whiskers range from 1 to 9.5, and the box ranges from 3 to 7. A line divides the box at 4. For the average wind speeds of cities in country B, the whiskers range from 1.2 to 11, and the box ranges from 4 to 9. A line divides the box at 6. Average Wind Speeds of Cities in Country B</em>

Country A

minimum: 1

quartile 1: 3

median: 4

quartile 3: 7

maximum: 9.5

Country B

minimum: 1.2

quartile 1: 4

median: 6

quartile 3: 9

maximum: 11

We can see that the difference between quartile 1 and minimum, median and quartile 1, quartile 3 and median, and maximum and quartile 3 is more homogeneous in Country B than Country A, then Country B is more symmetric.

Miss larner had a bowl of jolly ranchers sitting on her desk. One day sean decided to grab a handful of the candies and took 1/3

soldier1979 [14.2K]

Answer: 36 candies were in the bowl when the day started

Step-by-step explanation:

Let x represent the number of candies in the bowl initially.

One day sean decided to grab a handful of the candies and took 1/3 of the candies. This means that Sean took x/3 candies. Number of candies left would be x - x/3 = 2x/3.

Since he decided to return 4 of them, the remaining number of candies would be

2x/3 + 4 = (2x + 12)/3

Tracy also helped herself and took 1/4 of the candies in the bowl. This means that she took

1/4(2x + 12)/3 = (2x + 12)/12

The number of candies left would be (2x + 12)/3 - (2x + 12)/12

= 4(2x + 12) - (2x + 12)/12 = (8x + 48 - 2x - 12)/12 = (10x - 36)/12

Since she put down 3, the number remaining would be

(10x - 36)/12 + 3 = (10x - 36 + 36)/12 = 10x/12

Eugene grabbed 1/2 of the candies in the bowl. This means that he took

1/2 × (10x)/12 = (10x)/24

The amount remaining is

(10x)/12 - (10x)/24 = [2(10x) - 10x)]/24

= [20x - 10x]/24 = 10x/24

He put those two back. It means that amount left would be

(10x)/24 + 2

At the end of the day, there are 17 candies left. This means that

10x/24 + 2 = 17

10x/24 = 17 - 2 = 15

10x = 24×15 = 360

x = 360/10 = 36
