In interpreting a boxplot of a data set we note that the median is to the left of the center of the and the right line is longer than the left line. We can conclude that:. A) The data is skewed right.
B) The data is symmetric.
C) Skewness or symmetry cannot be determined by a box plot.
D) The data is skewed left.

Option A

Step-by-step explanation:

When the median is to the left of the center of the distribution with the right line longer than the left, we can conclude that the data is skewed to the right. Here the mean is larger than the median thus skewing the distribution to the right.

Representing this on an histogram including data will show a better description and also indica the longer right line.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
