Answer:
Karina is 2 years younger than triple Yuri’s age
Step-by-step explanation:
two subtracted from 3 times yuri's age
Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
Given:
Consider the below figure attached with this question.
To find:
The perimeter of the polygon UVWXYZ.
Solution:
All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.
From the figure it is clear that,
UV = 9 units
VW = 2 units
WX = 3 units
XY = 3 units
YZ = 6 units
ZU = 5 units
Now, perimeter is the sum of all the sides.



Therefore, the perimeter of UVWXYZ is 28 units.
