I already try, please help clarify correct answer, thx

The value of x = 13

The value of KN = 23.5

Step-by-step explanation:

Here are some of the characteristics of a rectangle.

Given the diagonals of a rectangle

KM = 4x-15

KL = 9x-80

We know that the diagonals of a rectangle are equal, so

KL=KM

9x-80=4x-15

9x-4x= -15+80

5x = 65

divide both sides by 5

5x/5 = 65/5

x = 13

Therefore, the value of x = 13

as

KM = 4x-15

so substitute x = 13

KM = 4(13) - 5 = 52 - 5 = 47

From the diagram, it is clear that N is the midpoint of the diagonal KM.

so

KN = 1/2 KM

substitute KM = 47

KN = 1/2 × 47

KN = 23.5

Therefore, the value of KN = 23.5

Summary:

The value of x = 13

The value of KN = 23.5

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

c is the correct answer
