Identify the five important values from this box-and-whisker plot. explain how you got your answers.

1.  median = 58

2. Upper quartile = 63

3.  Lower quartile = 55

4.  right whisker = 66

5.  left whisker = 46

Step-by-step explanation:

1. The most important item in the box and whisker plot is the median.

It is the middle line in the box .  The median is 58

2.  The upper quartile is the right end of the box.  It = 63  

3.  The lower quartile is the left end of the box.  It equals 55

The upper quartile and lower quartile are upper and lower edges of the middle 50 percent of the data.

4.  The largest data point, or the right whisker end point is 66

5.  The smallest data point, or the right whisker end point is 46

From these points we can find the range.  66-46 =20

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
