Answer:

30

Step-by-step explanation:

JL comprises of JK & KL. So ,

JL = JK + KL

Here the length of :-

KL= 9x + 3

JL = 55

JK = 7x + 4

So putting all the values above gives ,

7x + 4 + 9x + 3 = 55

=> 16x + 7 = 55

=> 16x = 55 - 7

= 48

=> x = 48/16 = 3

Using the value of x in finding the length of KL ,

KL = 9 × 3 + 3 = 27 + 3 = 30

What is the difference between discrete and continuous data? (Bar charts)
grandymaker [24]

Discrete data
This data set shows a group of discrete data.
This is called discrete data because the units of measurement (for example, CDs) cannot be split up; there is nothing between 1 CD and 2 CDs.

Continuous data
The data set shows a group of continuous data.
This data is called continuous because the scale of measurement - distance - has meaning at all points between the numbers given, eg we can travel a distance of 1.2 and 1.85 and even 1.632 miles.
Continuous data can be shown on a number line, and all points on the line have meaning and are different, but with discrete data only certain values have meaning.
