We have three sides in a triangle;
The third side is : x
The second side is:2x
The first side is : 2x+4
Then we have the following equation.
x+2x+(2x+4)=44
5x=40
x=40/5
x=7
The third side is x=8
The second side is 2x=2*8=16
The first side is: 2x+4=2*8+4=20
The sides of the triangle would be: 8 cm, 16 cm and 20 cm

{13, 17, 12, 21, 18, 20} has the greatest spread for the middle 50% of its data.
Step-by-step explanation:
Given:
Set 1={18, 13, 22, 17, 21, 24}
Set 2={17, 19, 22, 26, 17, 14}
Set 3= {13, 17, 12, 21, 18, 20}
Set 4= {18, 21, 16, 22, 24, 15}
To find :
Data set has the greatest spread for the middle 50% of its data=?
Solution:
Step 1: Re arranging the data sets in ascending order
Re-arranging data-set 1 we get,
{13, 17, 18, 21, 22, 24}
Re-arranging data-set 2 we get,
{14, 17, 17, 19, 22 , 26}
Re-arranging data-set 3 we get,
{12, 13, 17, 18, 20, 21}
Re-arranging data-set 4 we get,
{15, 16,18, 21, 22, 24}
Step 2 : Finding the interquantile region:
Interquantile Range(IQR) = lower median-upper median
For data-set 1
IQR=22-17=5
For data-set 2
IQR=22-17=5
For data-set 3
IQR=20-13=7
For data-set 4
IQR=22-16=6
Hence the data set 3 = {13, 17, 12, 21, 18, 20} has greatest spread for the middle 50% of its data .
