The value of x=10.5 units

Step-by-step explanation:

Here you should have in mind that in a parallelogram, opposite sides are congruent. In this case, AB=DC

Given the expressions, AB= 5x+7 and CD=7x-14 then you can equate the two for the value of x

5x+7 = 7x-14

collect like terms

7+14=7x-5x

21=2x

21/2=2x/2

10.5 =x

How do you determine the range and median of a Box And Whisker Plot??

lapo4ka [179]

The median ( Q2 ) divides the data set into two parts, the upper set and the lower set. The lower quartile ( Q1 ) is the median of the lower half, and the upper quartile ( Q3 ) is the median of the upper half. Example: Find Q1 , Q2 , and Q3 for the following data set, and draw a box-and-whisker plot.
